  1. 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 i
  2. 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.
  3. 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 h
  4. 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 Liabil
  5. 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 i
  6. Actually now I reread the applicability paragraph they do not include any of the J200 or J400 series aircraft which make up almost all of the current VH fleet. The models named are all those old types like ULs, STs, etc etc. And then only to certified models. So maybe this applies to very few or no aircraft anyway.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. 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 or
  13. 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 s
  14. 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 p
  15. 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.
