  1. I know what you mean Steve.I used to visit many US Sites, and was a little concerned at the lack of English skills shown.

    Sometimes I see similar incoherence here, and realize it is driven by frustration, I agree.

     

    There are good and bad L2's, we just need to maintain a dialogue between all, not so much to name and shame, but to let them know that they should try harder, not cut corners, realize this is NOT a way to make a living (unless you are really good) and that we do it for the enjoyment of working on aircraft.

     

    I did many years in the RAAF, and then as many years working at Bankstown.

     

    If we allow the L2 position to become as complicated as LAME, we have priced ourselves out of existence, just like GA.

     

    If you are an L2, take someone under your wing and teach them (but make sure you know what your talking about first!).

    Yes I agree, and most maintainers will network with other maintainers in search of best practice for task at hand, everyone has a special skill, engines, timber, glue, fabric, list goes on and on. As a group networking is the best tool in the box.

     

    As for making money out of it, not worth the effort for many, It bites into your own flying time. and the older I get the less time I seem to have, strange but true. As for English skills I dont care to much about it now and enjoy making errors, 5 years of writing Court Reports SBR's ECT, has left me somewhat relaxed in that area when I type.

  2. Rubbish. That may be what the rules say. I can assure you they are being floated... If Ra-Aus had of audited they would know.If what you quote is what CASA requires then we really are much deeper in the poo than even I thought. Basically a BIG chunk of the fleet is non-compliant.

    I dont think this type of talk is doing anyone any favors or your priviledge to fly under the current delegated CASA Administrator RAAUZ any good at all, in fact this will damage our right to fly, something that many have worked hard for years to achieve. we will be back to 95-10 single seat and 300ft AGL ALT limit if this type of behaviour continues.

     

    As for LAMES and L2 maintainers both maintain education on types they work on it is a perpectual learning environment. as it should be, methods and materials change as does the faults that are detected, the majority by far are dedicated to safety and good work , they would also read these forums I also suspect they would take note of who says what and black list them for any work, I hope they do as it is Insurance is High cost I am sure this sort of slagging would affect these cost including hull insurance if they believe what they read posted by some. Lets work toward positive improvement ok we failed Audits it is being fixed, humans make errors RAAUZ is ours look after it, This is the only way forward, I hope this will make sence to some or will all will end up with large expensive garden ornaments, bugger the spelling check i will just post it as is. Happy Flying Steve

     

     

  3. The U/L (and other European motors suitable D-Motor, Metalwork etc) would need to be certified before even an STC mod could be considered.Does anyone know if the importers/factories of any are considering Australian certification?

    the D-MOTOR Is a direct fit for the 2200Jab about 16500k to Auz side valve and puts out nearly 100hp @ 3200rpm now same weight nearly slightly lighter fitted, 2000hr TBO fuel injected smooth as safer with side valve if you get a failure fly on 3 without any risk ,has certification in Europe certification data is ok for all the overseas Airframes so why would engines be any different, this engine looks good and is a real contender for the 85 to 100hp needs even the Jab 6 power to weight and tourge output is broad and higher max hp comes on early and remains flat typical sidevalve love low revs which is ideal sorry about typos

     

     

  4. A couple of things:All engine hoses containing rubber-like compounds have to be replaced about every 5 years (for VH aircraft). It's not a bad practice to follow in RAAus planes.

     

    If you use rubber-like compound hoses forward of the firewall, you should cover them with a fire resistant cover called Fyresleeve.

     

    OME

    I must strongly agree with you on this, something that is ignored by many, fire sleeves on all lines engine side of fire wall, RAA auz factory built planes have to have it for certification yet kit built dont, I cannot understand that, totally nuts I have seen video of with and without involved fires huge difference in outcomes and that is why it is mandatory. prefer to see sleeves on both sides of all lines the rubber and all soft types are a fuel sourse in themselves let alone what runs inside, also tapeing the push through end of the hose to stop fibre entry during install, I have removed it from carbs before, and yes scheduled fuel line replacement as with VH rules.

     

    This also includes all rubber oil lines ie to coolers and filter mounts, even the breather line

     

     

  5. Well after only two years of flying the thrill has past, I've decided to hang up the flying jacket & go back to boating. I'm not sure what happened to the need to fly like i used to have, could have been the recent spate of aviation related accidents. Thanks to all the people who offered encouragment while I was getting my pilots certificate.Hopefuly the urge will return.

    Pete

    Oh hec Pete,

     

    Last time i did that mate i got caught in a storm off Kangaroo Island SA, thought i was a gonna for sure got the boat back in to the Cape and sold it the next week. I then purchased an Aircraft again, i love flying over boats in crap weather ha.

     

    Accidents are a fact of life and yes they can have the uncany was of happening in spates, but even during these periods you are at much greater risk of injury or worse each time you drive your car. this is fact.

     

    Do some time with a good bush pilot learn their methods precise landing, off field as well, it all builds confidence choosing tracks that traverse more friendly ground, enroute planning ect forward thinking know where the wind is and take note of paddocks and tracks that maybe useable at all times, then if you do have an issue all the important info is already in mind, just fly the plane , it works and if you get someone experienced to do some of this with you your confidence and enjoyment will return, it unfortunate that these days a lot of students never get to do real off field landings or even learn to read the ground well. hope this helps you bud, give it a try cheers Steve

  6. Im thinking about getting a plane for quicker travel but i cant afford more than $20,000. I was wondering what a good cheap option would be. I dont really care what it looks like etc just as long as it gets me there and hopefully has 100-120knot cruise speed. All advice welcome

    If quicker reliable got to get there travel is needed and cheap Hyundai i30 crdi under 20k, good low level performance, airbags and can do 100kts . serious though if i am in a hurry i take the car.

     

    as for aircraft you may pick up a KR2, That needs a tidy up for that 20k 110kts min a few are around and they come from a good stable,really depends on what sort of strips and conditions you fly, some dont like rough ground or need lots of runway so it pays to think about that first.

  7. I have had some chinnese whispers on the RV 7.It was registered with the smaller lighter engine....

     

    It may or may not have the bigger engine in it at the moment??? Dont know.

     

    It has one seat. It was built with only the necesary requirements. (ie as little as possible weight wise) to meet the required laws to be RAAUS registered.

     

    It has caused a lot of controversy not just here but else where, and RAAUS may not be able to register one again.

     

    This is second third or fourth hand information that is anonymous so I wont back it up in a court of law....

    YEP the RV"s up to spec, it is a pitty others dont just get on with flying and Stop trying to cause or hunt problems for owner builders trying to pioneer new types to our Catagory, I put the first Sonerai 2L on the AUF register Papa 028 , that opened lots of doors, in those days it was encouraged, CASA AND AUF put on the Permit to fly, 1 return trip to the Mangalore Airshow, they wanted it seen and shared with aviators.

     

    These days some pilots are just looking to try and cause trouble if they can or discredit them, why i dont know, maybe evenvy or just spite, who knows the old days of Mangalore and Lake Culleraine , Hopetown, St Arnaurd , Meningie, seem to have dissapeared.

     

    These spite full nasty types, one day be sitting in a paddock wondering how the hec to get there plane and self home again whilst being overflown buy a RV7 or A Sonerai maybe just a Thruster. payback is a bitch but it does happen.

     

    I know some of the guy's with high performance Aircraft and i know if i was stuck miles away out bush, they would be there in a flash and bring a slab and tucker, parts and tools. go figure what goes arround comes arround. PS The complainants never voice their concerns to the owners only to others , behind the bush gossip only, where is their integrity, Hmm

  8. I find it very difficult to understand how runway infringements such as these still exist, especially on a runway such as this where you can see either end. A simple but good look either way will tell you there are or are not aircraft on the runway or approaching or departing. If there is someone already lined up it must be assumed they are going to roll, unless clear and specific informatiom directly from them is assured otherwise. The Mustang used the radio as far as I can see, giving clear intentions. Judy had lined her aircraft up oblique to the runway so as to see aircraft on final and any on the airstrip. Unfortunately, the departing aircraft had to taxi down the last portion(~30metres) of the runway before turning and lining up. This led to a line of other aircraft being down the runway a little and some decided to pull out of line, enter the runway and depart. It seems just as Judy was rolling, the Jabiru decided to pull out of line, enter the runway and takeoff without warning. I believe it was Judy's passenger who saw the aircraft veer in front and immediately notified her. I'm sure the Jabiru pilot has learnt his lesson, fortunately costing little but the embarrassment and an extra nights cost for Judy and passenger who decided it was better to stay the night after such a close call. It's obvious now a marshal is needed when aircraft are not entering from the end of a runway. I think a little lest haste and more planning by some pilots, especially if suffering `get home itis` would alleviate the problem which happens at most airshows. We have held several airshows similar to Jamestown, and trying to minimise risks such as the above is top priority, but things always slip through the loop and are not realised until the day is over. Well done to the organisers for a brilliant day and to ALL the aircraft and pilots who flew in to make it so great. Safe flying

    I think a better procedure would be for all Warbirds to depart first, it will also save them from negotiating the flock of earlier departed Aircraft enroute all heading different directions at a much lower speed and various altitude. This would only add a little time and enhance safety . Lets not bash pilots or GA vs RAA standard operating procedures and Airmanship, this was an Accident I was there as well a great event it was, lets not spoil it , lets learn from it for next time . Thanks Jamestown

  9. Looks very interesting would be great for wooden props as well as providing ice protection for the airframe. oh the polish thing MCGUIRE Have released a marine polish in a blue bottle no silicon boats have the same concerns, very high shine i restored an old boat this gear did wonders for the color it conditions the gel-coat. I spoke to the company rep about the product, also it is fantastic on lexan windscreens ect you pay a bit more for this product but it works give it a try, hope this helps cheers .

     

     

  10. So how many times do you let your Jabiru try to kill you before you cut your losses?

    Ha ha well just fly accordingly height planed track landing areas ect, the old 2 stroke way a lot of us remember the old points type 2 bangers meeting lots of farmers, as for the Jab one of strongest airframes around the engine is great until the bolts break fix the bolts all will be fine , mine is great just want to make it better and as safe as possible, anyway you should anticipate engine failure on every stage of flight no matter what you fly.

  11. Turbo. While I understand and agree with much of what you say, people have to accept that risk is part of life. The only way to be 100% safe is by not partaking in life. Sit inside wearing a faraday suit hoping that a jumbo doesn't land in your lounge room. The threat of litigation is everywhere. Can you point us to any documented evidence where a raa pilot has served 6 years or one day due to a post accident litigation? I'm not saying it's not been done just I'm not aware of it. There's a bloke flying around in a a new r44 in this area, a little over 1 year since he made grave errors in judgment and had an accident which killed his wife.My cooments related to minimizing both sides of the risk equation. If pilots don't accept the risk and do all they can to minimize it, then they should not fly.I've re read all my posts and can't find where I said " be careful" or " I'm always prepared". If your going to quote a statement please be sure the 'statement' was made. Litigation plays no part in the thinking when people's live are at stake, if someone gets killed financial or libertarian consequences are secondary. IMHO.

    Reminds me of that old yarn about a bloke that insisted on getting the train to get to where he was going safely , he was killed during the trip a Plane hit the train.

     

    Risk and accidents are fact, all you can do is enjoy life do your best to be safe and reflect on human factors once and awhile when making decisions, But when things like better safer through bolts are available and our choice to use them is ignored because of certification issues which could be done very quickly, This safety factor is out of our hands, and is an unnecessary risk, why i don't know all things fail but common sense should prevail where a problem is known.

     

     

  12. In terms of the thru-bolt failure, is there any evidence that the new longer bolts and nuts are failing? In my mind this is the real acid test, everything before this upgrade is past events and falls into the history bucket and already known. There was an AD out to upgrade the bolts and/or nuts which had timed out for mandatory completion on the 14th April 2012... this AD also included crankcase dowels in some prescribed circumstances.We know Jab have added 0.5mm to lengthen the barrels or have fitted 0.5mm of spacers on earlier barrels to lower the compression to help manage the detonation .... to the best of my knowledge this has not been mandated to owners but has been a standard process during factory rebuilds since 2010 inclusive of new production engines.

     

    On the current production engine they have increased the thru-bolt dia as well as the longer 12 point nuts, along with a higher interference fit on the crankcase dowels ..... this is a significant improvement but it can't be preformed on old engines easily.

     

    In terms of retrospective upgrades today ... is there any evidence of the new longer thru-bolts with 12 point nuts failing????

     

    Cheers

     

    Vev

    Yes there has been failure, the new nuts fit the thread better than the 12 point nuts which have a better rolled thread, unfortunately the 12 point nut thread is given for the AD nut fix is a poor fit on the old machined threads on the through bolts, guess what a worker from the engine factory said they often had bolts fail during assembly, bigger bolts are not needed just better stronger material grade 8 through bolts as shown on the bolt forum with rolled thread and the 12 point nuts, these handle 2x the set tension of 30 ft ib 32 would be better, and safe but the old system of bolting had you on the failure point or so close its not funny, the quicker we get approved to use these WA grade 8 rolled thread bolts with double the strength the better, hell only $120 or dollars, we need to make some noise and make it happen it is a joke and hard to believe the resistant attitude of the powerheads, put lives at risk unnecessarily.

  13. Yea. I love the aircraft . It's a good solid trainer. I have major issues with the quality control and the service provided by the factory. I have had 3 online for a number of years and have dealt with every conceivable problem that could be imagined. I've given up dealing with them directly. We just get the problem sorted without their help. I could write a long list of QC issues we have had over the years. My favorite was a brand new propellor that let go of it's leading edge after a 5 min ground run.

    great Job guys, those bloody bolts, Andrew JP6 has the fix for that 3 x stronger rolled thread with the 12 point nuts that fit correctly, he is trying to get Rod's attention the supplied bolts are useless as is the AD, ROLLED THREADS STRONGER MATERIAL SIMPLE, the test on standard bolts can fail at the required tension, scary huh 30ft ibs the grade 8 rolled thread hang on to 60 ft ibs go figure, ALL PROVEN DATA.

     

     

  14. You could be right on the money there spacesailor, even if its full of bills etc.My chiro always went crook on me, because i'd drive around all day with my wallet in my back pocket. He said most tradies do it, and it actually twists your pelvis out of alignment. This then needs adjustment before he can loosen the other bits up.

    My backs giving me grief right now, says he who has just removed his wallet from his back pocket again.

     

    Idiots like me don't always heed his advise for more than a week or two.

    YEP WALLET, i have a lower back injury and having a wallet in the back pocket is bad news really quick, put it in the front pocket more secure, also the high density foam under the cover in the J120 works for me done a few 8hr trips without any probs, hope it works for you.

     

     

  15. best thing i have ever purchased, i have all the others and now i will stop subscribing, oz runways rocks, all data at your fingertips full OZ charts ersa aip real time wx radar vertical profiles touch a point for info or goto or add to route, you name it, fast stable app with high definition mapping and if ya get weathered in you can watch a movie and rock on your tie downs ha.

  16. I wonder if there would be any market for a small device that through some magic of materials science could cut or fracture perspex easily with minimal power such as muscle power and batteries.....

    Hiya guy,s what about a cordless angle grinder small and light, you would be out in a jiff as long as no fuel is leaking or you will be a jiffy fire starter, yep escape is a worry i sold my low wing for the same reason i stopped taking the kids in in it, i will stick with the Jab

     

     

  17. Oh hec this subject can get messy, AF picks up what the FED GOV fails to do for AUSTRALIAN TAXPAYERS fails to do for them, whilst spending the $ on illegals without thought of their own people who provided the funds in the first place, as for DUTY OF CARE THE LAW AND LITIGATION, where does mercy flights come in, in the last 10 years i know of 2 unqualified flights to a major town as mercy flights which were not challenged lives saved, but now we seem to focus on law and accountability rather than outcomes, i know if i needed urgent help i wouldn't care if i was flown by Micky mouse in a drifter to get help. oh boy what holes we seem to dig ourselves.

     

     

  18. It is not usually possible to tell if the prop is loose on the ground because the forces you can apply are small compared with what the engine delivers. So I wonder if putting some spots of a hard material (eg polyester resin) as a fillet between the prop and the driver flange would indicate if movement was in fact taking place. The idea being that an unbroken fillet would indicate no movement.This is such an obvious idea, along the lines of the paint spot on nuts and bolts, that it must have been tried before... does anybody know if it works?

    .... Bruce

    NO sorry it wont there is so much that affects your prop, they not only get loose but can get to tight as well , temp , moisture, expansion ect, you just have to keep a regular check of the tension as well as tracking and balance your engine and airframe will appreciate it, as well as your wallet cheers

     

     

  19. You said if you wish to transit these areas do it in a GA aircraft...what exactly makes a GA aircraft safer in these lanes? (at least when talking 4 strokes)I agree it highlights a problem... the problem lies with Airservices and is not GA/RA...

    Both vh reg and raa REG most of the TYPES NOW BEING FLOWN CAN HAVE EITHER REG, so it comes down to experience and qualification and approved equipment for the flight concerned, as for procedures for forced landings and slide rule boys, it comes down to knowing your aircraft practice and a shitload of luck, until you are confronted with it don't pick holes in others actions or decisions hindsight is not an option and a passenger adds to the stress especially kids when on board, GA OR RAA no argument exist, as to transit these areas, we do our best as any pilot does.

  20. How do you do the prop check Steve?Pud

    for tracking set all the hub bolts midrange tightness, place a static marker a telescopic antenna is good behind the blade you can tape to a stand of any sort, the antenna can be extended to a point where it just touches the trailing edge of the prop about 40 mm in from the tip is ok, carefully rotate the prop to the next blade if your lucky it will be the same however if the gap is wider that is the high blade, just add an extra 1 Ib tighter on that half of the hub and check again, the balance check should be done prior to all of that and is better explained off the net Brett Thompson propellers website has some good tutorials on there and diagrams ect, if ever you get a chance to get a dynamic balance done cost about $100 it is done on the plane running with spinner on i intend to get my own balance machine in time does a great job. hope this helps cheers.

  22. Good work Vev, sounds like I'll stick to the Shell Oil. Does anyone here actually wait until 50hrs to change the oil? I change mine every 25 and even by then it looks pretty 'worn'. I'd hate to see it at 50hrs... radioactive.gif.1acc918ae505c8835a1c29d9312871c0.gif

    because of trips overlapping my 25hr changes i have averaged 17hr changes, it is only a bit over 2 ltrs and gets a beating oil is cheaper than spanners keeps the internals very clean, drive em hard keep the oil fresh and service per the manual, stay up to date with the factory recommendations they told me about the shell 100 plus may be the go now, yesterday, so watch this issue from the factory advisory not shell agents as they are conflicting with advice, shell advised Jabiru about the 100 plus. and 25 hrs is max 50 is destruction just like cold oil changes are, hard to believe but dudes do it. And keep the prop in perfect track and balance the energy there is tons on that disk, it seems to be the most overlooked item that provides the performance on your aircraft. i have seen some really bad props, done a balance and track and the owners have been amazed at the difference like i can see the gauges clearly now as they were blurry, yep like Tyres on your car slowly wear until you have new ones you don't really notice; you get used to your environment, i do a prop check each service it is easy and just a bit of time and is kind to the airframe and crank and so on a chain reaction occurs, but hey this is only my view from what i have been told over the years from experienced aviators, and what i have experienced personally i hope this is helpful for some.

     

     

  23. Looks like I have to answer my own question.Weight of Jab 2200 inc exhaust etc 62.8kg

     

    Weight of 912ULS inc Gearbox exhaust etc 63.8kg

     

    So not much in it, still going to have over 270kg carrying capacity inc fuel in a Factory 170 after conversion..........

    DONT FORGET THE EXTRA 2KG FOR THAT 3 BLADE CARBON PROP considering the moment arm position you will need rear ballast.
