    With over 1000 submissions there will be some considerable change to the proposal and then the next round of submissions.

     

    AGL cannot be legislated as no-one has the ability to determine this with current equipment. It will have to be expressed and specified on the VTC & VNC as AMSL.

     

    They have determined it is to be implemented in the medium & high density areas & the next round they are going to provide proposed maps with these areas drawn in (so they say).

     

    They have stated it is to enhance safety without providing any safety concerns at all or any historical safety related incidents and one of the latest fatals was very much an Airservices failure suitably swept under the carpet in the final ATSB report.

     

    CASA is the authority that will have to legislate and implement any change and they found out about the proposal the same way that GA & RA pilots found out.

     

    I could go on for another 3 or 4 pages but there is no point until the revised proposal is released with hopefully more detailed and sensible changes and a longer industry consultation period.

    Broadly I agree with you.
     

    Couple of points that I disagree.


    AGL: I agree it should be AMSL but Currently anyone with an iPad and OzRunways can read AGL with a reasonable degree of accuracy.  Radar AltImeters have been around for ages and are available but extremely expensive. But there’s  no need for a rad-alt if you are able to accept a small degree  of error in the GPS altimeter. GPS Altitudes are Probably within the limits required. ( with the ground elevation data loaded ) I’m not sure about Avplan but I’d be surprised if it didn’t have it either. 
     

    The point of this though is that it’s another imposition of cost. A grand for an iPad that needs updating every say 4 years, a subscription to OzRunways, maybe they’ll dictate a backup iPad as well and an external GPS antenna. Maybe a SIM card etc for on the on the fly updates.  All a not insignificant cost. 
     

    Step backs in negotiations as a result of the huge negative responses are not cast in stone. They have suggested they will look at modifications but at no point are they either required to look at less onerous proposals nor are they required to actually implement any less onerous versions. 
    My  experience with bureaucracies is that the pushback must be maintained at the level of and against the first level of proposals all the way down to no change until the final proposal  is solidly cast in stone. The slightest relaxation of the defence position will be grasped and some intermediate level will be put forward as a compromise or a “win-win” position but will soon be used as stepping stone to re-approach the original proposal. That’s Negotiation 101!

    Jaba, you refer To Avmed doctors, but the people who over rule the DAME are not doctors, they are clerks reading a checklist and nor necessarily understanding it. I am sure I am not the only one to have a specialist perplexed at their questions and requirements, or have the DAME's decision to issue my medical overruled. 

    Ummm no. As much as I dislike the system and feel I am as highly qualified in some aspects of my specialty that pertain to aviation medicine I have to disagree there. 

    The doctors in AvMed who set the standards by which the clerks copy and tick the boxes  are real doctors. However their qualifications are in a branch of medicine that is somewhat esoteric, whose basis is heavily slanted toward the rigours of military aviation and whose parameters of “normal” often  err on the side of an over abundance of caution.  The  principle being “Safety!   to the point that we throw out anyone who might possibly have even a minimal risk because there’s plenty more where they came from. “
     

    Their concern over the desires  and aspirations of the individual who wants to undertake the far less risky recreational jolly in a weekend are a big fat “zero” 

    As such the doctors set up a set of check lists, whose box ticking can be done by an underling, but they are still the ones who make the final decisions when a pilot appeals because the boxes contain crosses instead of ticks. 
    The  problem is they are out of touch with reality and the levels of fitness actually required and have decreed crosses where many in the real world of managing these patients every day would say that a tick is more appropriate.

    As I understand it NZ PPL's are accepted in Oz. Also as I understand the CASA RPL is not acceptable elsewhere in the world. So the challenge for CASA will be whether to subdivide NZ PPL's on the basis of the medical used or simply admit NZ PPL in total, which means that NZ pilots with basically the same licencing basis as a CASA RPL can jump into a Beechcraft Baron with 5 passengers and tour around Australia at upto 25,000 feet, in and out of controlled aerodromes.

    Given the various treaties with NZ, CASA will have to move carefully.

    I don’t think there’s a problem as you perceive. As far as CASA is concerned a pilot has two qualifications - one an aeronautical licence the other a medical certificate. They are seperate things and a person can have either alone  but you must have both to exercise the privileges  in the aeronautic licence. The issue of an NZ or any other country pilot coming to Aus is already covered. You must have an aeronautic licence that is acceptable to CASA and you must have a medical equivalent to the Australian medical required for what you want to do here. It will almost certainly require a trip to a local doctor to get a local medical.

    Without a demonstrated need for this equipment I do not feel like paying out a fairly big sum of money for the small amount of flying I do.

    I agree it would be safer if airlines could see us, but it would be much safer if we were not there. Every time we go along with these safety items that cost us money we are giving the powers that be encouragement to screw us more.

    That is the real issue here Yenn. 

    here is a new rule carrying considerable cost ( In sorry SplitS but this is not negligible cost. It’s yet another imposition that adds to the other unnecessary costs like ASICs and  medicals, and the necessary costs like insurance, hangarage and fuel etc that gradually squeeze people out bit by bit.
    To someone who is eg. on a pension, flying their beloved ol’ home built,  on cheapest fuel they can buy and paying for hangarage by doing odd jobs and mowing around the airport the requirement to spend a grand extra to fly is a major imposition.
     

    Even more painful if they fly in an area with very little or no RPT (the area ASA are wanting to designate class E is not just around airports where the RPT descend but essentially the whole east coast between airports even where no RPT ever fly. 

    This is not being nasty SplitS, and please take this with the non-judgemental spirit it’s meant,  but your sentiments also carries a bit of impression that it doesn’t affect yourself so as far as you see it doesn’t affect anyone else. This is  ASA/CASA’s modus operandi. Divide and conquer.  Recreational aviators need to always try to see things from everyone’s point of view, especially those who might be affected by something we personally are not. It’s amazing how quickly these things end up being turned on us after the original target is shot down!   
    I don’t know where you are based but I see this potentially directly affecting a very large number of RAAus pilots who live on the east coast. (Doesn’t affect me at all (yet)  - I’m GA and have an allowable transponder set up and a disposable income to buy a new ADSB in or out so I’m not complaining on my own behalf (directly)  I’m not whinging for my own position rather for my fellow aviators who are impacted here in North Queensland and for the lead in issue this creates - see next bit!

     

    The second really important part of it is, here is a new rule being instituted with no case made for its need apart from the hoary chestnut of “enhancing safety and if you question it you must be against safety and therefore you are dismissible”. No case for why it’s needed but it has restrictions placed on those with the least capacity to respond.


    The real question is that this smacks of a lead in restriction that once established will be the precedent for something else. I don’t know what but I can see this being the pre-emptor further restrictive airspace rules - like suddenly Class E will see  RAAus  have same restrictions as current Class D and C. 
     

    The rules about AGL ( vs MSL) clearly require more technology to establish AGL position. Once that’s in law there’s another cost that might get sprung into RAAus as well. 
     

    This sounds like it’s part of an agenda. There’s no reasonable reason for it otherwise.

    Well here is the latest 2021 version of the form that can be completed on line.

     

    https://www.pdffiller.com/en/forms.htm?projectId=659098342&blank=1&transactionId=7579773b7f0c8d39b3e47be6d6025a04&requestHash=907eb05a9ec17b016168c16bf2a6382a4350c457f35f2f4773d9d4d7b60f4025

     

    On page 2 the only reasons for requiring a medical certificate is 1. over age 75, 2. applying for a truck licence, 3. have a medical condition that has affected your ability to drive safely in the past 5 years.

     

    On page 4 it states "You must prove your eyesight is up to standard, You can

    • pass an eyesight screening check at a driver licencing agent, or
    • present a satisfactory eyesight certificate or medical certificate (no more than 60 days old)

    The form is multi use and if you have done everything it can be saved and emailed to NZTA or you can print it off & take it there & do your eyesight test there at the same time.

     

    The eyesight test in NZ is more specific than in NSW. At NZTA they have a binocular tester on the counter & each eye is tested to different levels. I did my last one there in 2004. I did one last week at Service NSW.  I stood at the counter & the girl at reception put a 3 line chart on the TV screen behind her & asked me if I could read the middle line. I read it & she said no worries you don't need glasses to drive. Actually as far as I am concerned I do need glasses to drive and also to fly as I like to be able to read signs and number plates from a long way off not when I am almost on top of them. Flying without my glasses & I can't read the instruments clearly or see clear detail at long distance like other aircraft or eagles.

    Ok The answer here is in the details. 
    ( That link doesn’t work - actually just web service that allows you to fill in PDFs online without having the expensive Adobe or similar version - but no matter it’s not relevant ) 

    I was looking at the legislation from 2018. I assumed it was the latest but maybe the 2021 version has changed. 
     

    but 

    The kicker is your line that says “2. a truck licence. “. So the legislation  says a medical suitable for a class 2,3, or 5 ( with passenger carrying privileges) Vehicle licence. So that immediately means truck ( the classes are outlined in another of the linked publications) licence of one sort another.  So by inference a DL9 for a pilot licence will have to be one where you see a doctor and that is also stated  in the article attached to the original post. 
     

    still better than the Australian Class 2 basic but not as easy or self determined as an Aust RAAUS or a US Basic medical.

    The RPL was introduced in NZ in 2005 largely to allow ageing pilots to continue to fly without a Class 2 medical so is completely different to the RPL introduced in Australia 10 years later. There are actually only 195 RPL licence holders in NZ. With this DL9 drivers licence medical introduction the RPL is being revoked and all holders are being issued with a PPL with a few privileges removed as per the table link above. The DL9 medical is a simple medical to ensure (mostly older) drivers are OK to drive a car. It is used as an endorsement for forklifts, dangerous goods tracked vehicles etc as well. It is largely a self declaration of medical fitness but requires an eyesight test that you can do for free at any NZTA office. Basically it is the same as the RPC self declaration medical with an eyesight test. If you are older than 75 then you have to get it signed off by a doctor, same as for the RPC here.

     

    So it means in effect if you have a car drivers licence, fill in the form on line, take it to NZTA, get your eyes tested, (if over 75 get your GP to sign it) pay the fee & you are good to go GA PPL flying.

    I am not in NZ and only going by the rules I found by googling so may be ( and will happily accept if I’m an) wrong. 
    But the DL9 is not just a stand in line at the traffic office eye test. 
    Nor  is it a self certification. 
    I’ve read the relevant stuff from the NZ government DL9 guidelines for medical practitioners  ( downloadable file 133 pages)

     

    A real drivers DL9 is a formal medical examination that can only  be conducted by a doctor, an (qualified) optometrist, a qualified nurse practitioner or a registered nurse working within a current scope of practice. (According to the Act ) 

    The pilot DL9 sounds like it has to be done by a doctor. Seems like that is the only additional restriction compared to a drivers DL9 but that’s just how it’s written in the publication provided. Might not be absolute. 

     

    The standard ( private driver (Class 1 drivers licence) vs Commercial drivers licence ( Class 2-5) is surprisingly not that different.

     

    Essentially all the same fairly severe medical conditions preclude both and the differences are in just how stable some conditions have to be to maintain the class 2,3,4 or 5 components. 

    For example. The difference between private and commercial having had a mini-stroke is a few months of stability. 
    (In Australia you will be lucky ever to get your pilot  medical back at all. )

     

    The age limitations in NZ are:

    Age less than 40 it is required every 5 years

    Age 40 - 75 ( oops I forget this exactly -could be 70) required every 2 years 

    Age over 70/5 every 1 year. 

     

     

     

     

     

  7. After going through both Aust and NZ standards my opinion  FWIW, is the New NZ standard is somewhere between  the Australian Basic Class 2 and the US Basic Medical. Not  that far ahead of the Australian Basic Class 2 but enough to make a difference to some  pilots. 
    I have gleaned the following comparisons & differences. 
     

    Medical

    NZ (DL9 medical): Basic drivers licence medical with NO use of conditions to further limit gaining a medical. 

    Aust: Commercial licence standard with overriding conditions that can fail the medical even if pass it for an actual vehicle licence ( I know at least one pilot who has and uses a commercial vehicle licence but has been denied a class 2 basic due to the conditions) 

    NZ: The doctor decides if the pilot is fit to fly. There is actually a section on the medical form  where the doctor gives his/her opinion. 

    Aust: AvMed decides if the pilot is fit to fly. The doctor carries no weight, and  is merely a box ticker who looks to see if the pilot reaches predetermined levels and in practical terms passes that information to AvMed. The doctor has no capacity to give an opinion or adjust the conditions which generate a “pass”. ( Even specialists are overridden by the AvMed doctors in every level of licence) 

     

    For both the time intervals are the same. 
    The costs are similar. 

    My opinion:

    Clearly the medical component is the thing that effects more pilots, particularly given our aging pilot population.

    The US ( and our own RAAus medical system) has proved that medicals (beyond those for people with really severe conditions such as uncontrolled epilepsy,  some cardiac and psychiatric conditions), are actually, in practical terms, unnecessary for pilots. The NZ new system is clearly a step toward the US and is to be applauded from that position.
     

    It is clearly more lenient than the Australian Class 2 basic which by virtue of the added  “conditional” limitations has blocked a lot of pilots. I  know of pilots who now fly without a medical ( and have done so for years) because the Class 2 Basic is closed off to them due to “conditions” and it is not time-practical or cost effective to get a class 2.  

     

     

    Privileges of each:

    For most pilots these are comparable but for some pilots it will make a difference and in most cases the Australian  medical is more restrictive than the NZ. 
     

    The only “better” situation in Australia is aircraft weight. ( I forget the exact MTOW but these are close enough) Australian is about 8000kg and the NZ is about 2500 kg. 


    For the rest the NZ situation is either better than the Australian or same.  
    NZ exercising of endorsements

    Acrobatics:

     NZ - yes but only when solo above 3000 ft

    Aust - No. 

     

    Night VFR:

    NZ - Yes but only within 25 nm of a lit airport

    Aust - No

     

    Instruments - No in both

    Passenger numbers - 5 in both

    Engine types - piston both. 
     

    For most people the differences are minimal or not going to change their flying. 

     

    It’s also interesting that all NZ Recreational licences ( now equivalent to Aust RPL) will automatically be granted a PPL. My own opinion is that this removing of multiple licences that cover essentially similar privileges is also a good thing. Streamlining and simplifying makes a lot of sense when trying to set up things like medicals and limitations.

    Ahh! Those Russians!

    I’m assuming you are referring to the urban legend about the US space program spending millions to develop a pen that would work in zero gravity but the russians just used a pencil. 

     

    Just as a bit of interesting side info:

    I heard that it’s apocryphal and that no one, not even the Russians, used a pencil because pencils give off microscopic fine powder of graphite into the air when used.  In zero gravity the graphite powder  floats about in the “air” in the capsule environment and shorts out electrical equipment. 

     

    Can’t vouch for the veracity of this but gives an interesting twist on the urban legend.

    You may find that the labels made by those machines just revert to their base colour when exposed to  (not very) elevated temperatures. I bought a nice one like that and it made great switch labels for the cockpit, but my spark plug lead labels in the cowl  turned completely black very quickly.

    That’s very useful to know. 

    I had a look at the webpage of the device after the first posting above and was thinking that despite the cost  it might still be worthwhile if it makes making the labels quicker. But sounds like back to my old method.

    At the risk of being boring I repeat:

     

    Not sure why you want to label engine compartment cables - they are mostly short runs, that terminate at a point that makes their application obvious.

     

    Behind the instrument panel - different story all -together.

    Without being boring same answer as before. 

    They are  not always short, ( but short doesn’t mean they can’t be convoluted and impossible to follow), they are loomed, they are not always obvious, and there are lots and lots of them. Your statement might be reasonable if it was an accurate description but it is just not correct.  

     

    If one wire disconnects OK it won't be an issue but it is not  helpful especially when multiple wires are disconnected. 

     

    Even following a spark plug lead that came off the distributor can be a one second job with a label on it and a half hour job with out it. 

     

    Eg: Ok -let’s make that 2 leads pop off or are taken off the distributor

    To correctly reconnect them   (:in a jabiru especially) will require removal of the ram air ducts so you can follow the lead all the way to the cylinder, [that may require removal of the bottom cowl in some aircraft ( I have seen a couple where the removal of the front cap screw holding the ram ducts needed the bottom cowl removed,] cutting all the zip ties  of all the wires in the loom to follow and ensure you have the right lead, then check again, then run the engine and if it there’s a problem recheck it all etc etc. 

     

    or

     

    simply pick up the dislocated ends, read the label and reinsert it onto the distributer, followed by repeat for the second lead. 

     

    Same applies to 6 CHT leads, 6 EGTs, an oil pressure sender wire, a back up CHT sender wire, the multiple wires to the regulator, solenoids, master relay, Amp high and low shunt sender, fuel flow sensor wires, Radio wires that go directly to the battery, hard wired strobe light wires.

    To say they are short and obvious is not a factual representation of the state of engine bay in many aircraft these days.

    Maybe, but let's work on the previous 65 units as an example.

     

    If CASA only received reports from 4 owners regarding cracking, there are 65 out there in unknown condition; they might all be OK, or some people may not have got around to checking - too important for a safety issue to just leave it hanging.

    If CASA receives 4 reports indicating cracking, and 61 reports indicating no cracking, it has an accurate assessment of the spread of the problem.

    I've always solved similar issues by phoning every customer - makes a huge different in keeping the fleet working.

     

     

    But the point here is that if any of those 61 forget to contact CASA AND EVERY  owner of the thousands of RAAus and LSA owners don’t contact Jabiru or CASA ( which they will because they are mot required to ) 

    then the very small number of the VH aircraft become meaningless in the mix. 
     

    But to get back to my concern - it’s not the statistical validity  or lack of it I don’t care about reporting a crack if I find one - it’s the fact that if I forget to tell CASA I had NO cracks or if I do tell them but my response gets lost along the chain through CASA then given the Strict Liability function of just about all aviation law then I will be guilty of an “aviation crime.” Without mitigation. 

    That’s what  I said right from the start but everyone seems to have missed that. 

  12. 3 hours ago, RFguy said:

    and when I said
    "there are probably quite a few cracked below the 4000 hours"

     

    - that is purely based on probability.  is a bell curve.  If there are tubes cracking > 4000 hours, there will likely some non zero number cracking 2000-4000 hours.

     

    Nope. That is choosing  the wrong type of statistical analysis for this situation. 
     

    Statistically speaking it is not possible to produce a valid bell curve from a single event. You must have some cases above and below the mean so that a gradient can be made to find the standard deviations etc. A single case can only produce a linear spike on the x axis. No statistical capacity to produce a bell curve. 
    That’s assuming a true single case event and in the entire history of jabiru ( some 30 years) this appears to be the only event ever reported. 
     

    so the single event happened in an aircraft with just over 8500 hrs. ( According to JSB042-1)  Not 4000 hours - that’s the arbitrary selected hours by Jabiru to make the inspections. 

    But Ok - Assuming other cases (?which there is no evidence ) enough to produce a bell curve - there is a reasonable chance the approach to zero line in this fictitious curve may be so flat below 4000 hours that it reaches the near zero Y axis line and therefore for all intends and purposes is zero. ( In this type of statistical analysis you can’t have less than an integer value  of 1 case - you can’t have say 0.5 aircraft having fractured control rods. It has to be 1 or 2 or 3 etc. )  
    So it is entirely  possible, in fact probable that there are  zero cases below 4000 hrs.

    I understand your beef is with the mandatory part of the reporting.

    Thruster said: "non VH report defects only to the manufacturer" For those aircraft the manufacturer might be doing the mandatory reports?

    If the RA owners are not reporting to the Manufacturer or the Manufacturer is not reporting to CASA, then I agree, the system breaks down.

    Nope you miss the point.
    there is no problem with a mandatory report of finding a crack when one is found.  
     

    The AD requires owners to report when NO crack is found and that is mandatory.
     

    There is no requirement in the SB to report that NO Defect has been found when doing the inspection. The manufacturer will NOT be reporting to CASA that owners have not reported when NO crack is found.
     

    The only people who stand to get into trouble and ? be fined and held accountable is owners of VH Aircraft who don’t report that they have NOT found a crack.

    Having worked for manufacturers all my life I know the frustration of having product failures of all types; 

    • Intermittant failures where some products would fail
    • Life cycle failures where every product would have a failure after a certain number of hours or distance
    • Irregular failures where all products would fail, but at different times.

    We will usually fix all problems we can find, but the frustrating thing is only a few customers ever tell us, and we have no means of knowing which of those three types of problem it is unless we get data in.

     

    With life cycle failures, we can replace the suspect part at a regular service under the failure point, or we can call the product in and provide a loan while the faulty product is being replaced - sost the customer nothing.

     

    Irregular failures are handled by stocking up on replacement parts and providing loan products

     

    Intermittant failures are the most difficult because it's so difficult to diagnose what the cause is. 

     

    Air Bags in cars are blown up by the blast from a charge of Ammonium Nitrate, the same material favoured by terrorists. Takata got something wrong in the engineering and metal fragments started killing people. The airbags in our cars were replaced by the dealers during routine service so it never cost us a cent. However maybe ten years after the event there are still about 30,000 Australians who will not bring their cars in for replacement air bags.

     

    So in the automotive and transport industries we have this blind spot where we research as best we can from part of the population, but the rest don't find it necessary to tell us enough to make decisions in there interest.

     

    In the aviation industry we have a Safety Authority which adds another layer and are given tools to compell people to provide this information.

    How much safer is it to be able to look at reports from all the VH Jabirus and know that 0.6% have cracked at 4000 + hours, but 99.4 have not, That tells me that there is no reason for any owners to have to replace the tube under 4000 hours, and more research is required on the 0.6% before committing to replacement at 4000 hours.

     

    Armed with feedback an Engineer has a much better chance of fixing the problem.

     

     

    Nope - too much extrapolation to non-relevant scenarios. 
     

    There are only 65 Jabiru’s on the VH register.  They form a statistically irrelevant cohort in the overall fleet across RAAus, LSA and GA. Any figures collected from them will be irrelevant to the overall statistics and interpretation of those statistics.

    Hi Jaba They say only one aircraft in Australia is affected, is that yours, VH?

     

    I drove past Atherton on Sunday and airfield looks nice, actually stayed overnight at the next door park and now in Cooktown.

    Hi Blue

    Nope mine wasn’t the one that it happened in. That was a training aircraft somewhere in ?NSW that had about ?8500 hours in it. 


    Atherton is a nice airport. Grass strip, no landing fees. Can be a bit gnarly at the northern end in a  cross wind. Pleasant aviation community there.

    Jaba, this AD only applies to VH jabiru's. All  jabiru's are subject to JSB 042-1. The manufacturer has rightly stated that all SB's are mandatory so the AD is a waste of time, another unnecessary duplication.  Only VH jabiru's must report results to casa, non VH report defects only to the manufacturer.  Reporting all results of AD's is not unusual.  

    Actually it’s not usual and it’s never happened before as far as I am aware. 

    I have not seen another AD in 25 years of doing maintenance and owning aircraft where AD  inspections must be reported to CASA that NO DEFECT has been found. The AD being complied with gets written in the aircraft (and engine log book  if applicable) maintenance log book. 
    That’s the bit I interpret as being a problem. 
     

    It says the results of the inspection must be reported, which I read as even when no crack is found.

    Yes, RF this is just a routine CASA safety message, precautionary to the owners and doesn't imply every one is going to crack.

    Probably just CASA wanting to collect data with x number of zero cracking and Y number of cracking.  How long does the inspection take?

    That’s not the point Turbs. The inspection which I have done severally times now since the SB came out takes about 30 seconds. 
    what is the problem is that if I forget to report to CASA that I did the inspection, and found nothing, then next time I go flying I have breached this AD and have committed a crime.

    yeah... Aileron Ctl Torque tube from the rear of the stick. there are probably quite a few cracked below the 4000 hours.

     

    I have looked at two since that P-AD came out last week , both were not cracked, but both aircraft < 1000 h.

     

    There would be some Jabiru maintainers here that would have seen a few, their comments would be interesting.

    What???? 
    No evidence of ANY and you even looked at some and there was no evidence of any but still saying “yeah there probably are quite a few cracked below the 4000 hours.  “
     

    Someone will take this post and say “yeah, some guy on a forum said yep there’s quite a few of them so yeah CASA should be clamping down in bloody Jabirus again! “ 


    No wonder Jab owners feel like a threatened species. For what it’s worth,  where I am there about half a dozen Jabs and I’ve not heard of anyone having the problem. 


    For a touch of reality. 
    CASA have had over a year since the original SB was put out by Jabiru. Since then, if you go by the wording of the PAD,  there has not been any or another incidence of this problem. The report clearly says there has been one case which we can take to be the original case. 

    Now the way I read it, it is a requirement for essentially all Jabirus, depending on how you interpret the convoluted Applicability paragraph. But that’s not the problem. I have no issue with it being part of the 100 hourly. It’s bugger all as far as an inspection goes. 

    But I’m left not being sure about the reporting paragraph.

     

    “2. Report the results of the inspection to CASA via the Defect Report System.”

     

    It seems to me that once the inspection is done, then this AD requires me to report to CASA the outcome of the inspection, whether a crack is found or not. So every year, assuming no problem is found I still have to report to CASA and if I don’t then I am in breach the AD. I stand to be fined or have punitive action taken against me for not reporting that I have not got a problem. 
     

    I’ve  never come across any AD in over 25 years of flying where I am required to report to CASA when there is nothing wrong with an aircraft. 
     

    What’s going on here?

    jim Weir of Kitplanes described using the resistor code colours for marking with shrink wrap. He had a system that had for example all engine wires starting with 1 and all instrument wires with 2 and then a further three numbers. The start end also had to be marked.

    Really unless you have a very complex engine there is not much wiring that is not apparent in its purpose firewall forward.Starter cables are heavy, alternator cables a bit less so, CHT and EGT are lightweight and visibly traceable. Wires going to relays can usually be seen easily.

    Not true anymore I’m afraid. 
    add 1 skyview or any of the many EFIS/EMS now available at cheapish  prices to your aircraft and you can have 20 - 30 wires going through your firewall.

     

    As soon as you loom up wires (especially the EGT and CHT wires or any wires that are similar size) you lose identity of every one of them. One breaks and you have to pull the entire loom apart to identify just one wire and which cylinder etc it’s off. 
    Been there done that! 

    The  colour code system seems a lot of trouble  - write ( or laser print in English on a bit of paper under clear heat shrink.)

    Same fire risk. 

     

  20. Seems the original quest was for something that was fire/flame resistant. 
    None of these ( except maybe  the use of coloured Tefzel - which is  available. ) But doesn’t really  provide a foolproof easy labelling system ( since you need a copy of the code with you. Inevitably  you have a problem at a far off strip and you end up without your code book or you end up in a loom with multiple wires of the same colour etc ) 

    Frankly  I don’t know of one either but I decided to take the risk and just label things in English properly -  use short bits of clear heat shrink with a laser printer printed (size 8 font) paper strip under it. The short bit of heat shrink might be flammable but in the grand scheme of things the heat shrink bits are about a couple of cm long so the risk is small but the gain in labelling immense. 
    Have completely rewired my Jabiru multiple times and worked on parts of the wiring etc many times. And when it comes to working on it easily you really need every wire labelled at both ends with a text label. No need then for codes and records. 
     

    If someone produced a heat resistant heat shrink equivalent I’d use it in a flash  but so far not found anything that works as well as a printed label under clear heat shrink.

    Well the plane crash victim only got 1.5 million, not 15 million, so RAA members with RAA PL Insurance would probably have had that one covered.

    I haven't been following to payouts to make a current judgement, but it would pay to have about $15 million if you take up a passenger to cover the chances of the person becomeing a quadriplegic and requiring lifetime care, and a lot more if you are flying at airports where RPT regional services operate in case you kill multiple passengers.

     

    That incident is complex because several people were suing several other people, and there still could be more cases to be heard involving different plaintiffs and defendants, but there should be a transcript available somewhere so see which points of law were considered and ruled on.

     

    However, with suitable PL Insurance you shouldn't have been ruined in that type of incident.

    Last time the RAAus insurance was raised on this forum  I looked at it and read the actual schedule.
     

    As best I recall the maximum payout for a single incident for personal injury was $250,000.
    The stated $10M in the headings of the cover is for non-personal injury stuff - structures, other aircraft etc. 

     

    so in this case the RAAus member might  be left in financial trouble.

    According to RAAus this Brumby has a Rotax 912iS. That is a least 6 engine power loss incidents involving iS engines in 2020 that I am aware of. 

    Wow. Does this mean CASA are going to do the same as they did to Jabiru a few years back?  
    Somehow  I doubt it. 

  23. Lakeland Downs in FNQ 

    Early Dry season, grass was a bit long but OK, and all brown. Landed a bit fast and had the original Jabiru brakes so not much use. Suddenly I was in among a huge mob of wallabies that had merged into the grass and suddenly they were going in all directions. Suddenly out the other side of the mob. 
    No idea how I managed to avoid hitting any of them.
