  1. Also, most aircraft manufacturers seem to have long waiting lists at the moment. If customers are buying as many aircraft as you can produce, at the list price, why would you lower the price? Good old supply and demand. Special deals are usually offered to sell surplus stock, but most aircraft are manufactured in low volume, and only built to order, so there is rarely any surplus. In this age of "just-in-time" manufacturing and supply logistics there is less chance of stock surpluses in any industry, but manufacturers might offer deals if their factory is operating below full capacity. I bought a mid-range farm tractor last year, which is still a relatively low volume product but still many times that of aircraft, and it didn't start on the assembly line until I signed on the dotted line.
  2. Jabiru 3300 engine- Our price from Jab Australia= A$20,900 (~US$14,600 @ 0.70 exchange) US price from Jab USA = US$18,900 Not sure if that supports my point or not. That's the Oz retail price so Jab USA would surely get it cheaper than that..but maybe not. ?
  3. Getting back to SDs original point, that the Rotax prices are the same everywhere and therefore must be rigged...I think it's good old economics 101...Supply and Demand. Rotax engines are a specialist low volume item, so no supplier around the world ever buys an amount that would attract a discount. Rotaxes aren't that big in the USA either so there is not the competition to drive prices lower there either. So I'm guessing the Rotax price around the world is pretty much set by the factory price (no volume discounts) plus exchange, freight and a profit/warranty margin. I wonder how Jabiru engine prices compare around the world? There are plenty of Aussie products that are sold cheaper in the USA than they are here on our shelves. We are a low volume market and are used to paying higher prices so we get charged more, even for our own products.
  4. I can't believe it either...and yet it seems to be all too common. What is it about aviation that seems to attract dodgy operators? I don't know how these people live with themselves. It makes doing a build myself more and more attractive. Is it time to name and shame?
  5. Thanks Garfly. I accidentally copied a truncated link and didn't check it. Annoying that you can't edit posts after a certain time.
  6. I apologise if this has been posted elsewhere, but I just came across the Coroner's report for this accident...released back in July 2018. Interesting to note that the Coroner is himself an RAA member and pilot and also holds a PPL. Coroner's findings into the death of Ross Millard
  7. I always understood Va (or probably Vb is more accurate) to be the speed at which the wing will stall as a result of an excessive vertical gust (turbulence) therefore unloading the wing before it reaches its maximum G-load. This speed gives you an automatic safety valve against excessive G forces. Interestingly the lower your weight is the lower the safe Va speed is if I remember rightly.
  8. Ethical or not, exclusivity deals are all around and standard practice. Businesses want a return for their sponsorship or advertising dollar. I don't know why Restriction of Trade doesn't apply...but it happens all the time. Coke or Pepsi give milk bars flashy fridges at no cost on the proviso that the competitor's product is not sold there. Do we kick up a fuss if we can't buy Pepsi at a certain store because of restrictions? When Bose put their audio products into retail stores the stores got the advantage of the slick marketing of Bose displays...but those displays had to put somewhere where they could not be demo'ed or directly compared with any other audio products. Marketing. Aviation is such a small market in Australia with only a few players and small consumer base. Perhaps the mistake made by AVA is that there is not room or tolerance for marketing ploys like this in a such a small and close-knit consumer group as aviation is.
  9. Yeah sorry...typographical brain-fade..meant 99 not 89.
  10. I fly REX fairly often and have found them to be a good airline that usually keeps a good schedule. I haven't seen anything (so far!) to cause me concern about maintenance. The SAAB 340 airframes are getting on in age (production finished 1989) but apparently have a lot of hours/cycles left in them to last quite a lot of years yet. Talking to a REX pilot a while back, he doesn't know what they'll do after that as the REX business model is very much built on the efficiency of the SAABs. Apparently they are far better on fuel than any of the competing turboprops such as the Qantas Dash 8 or Virgin's ATR 72. Without REX a lot of regional cities would be left to the mercy of Qantaslink or have nothing at all. I have no interest or shares in REX.
  11. As far as the risks go RPT airlines are the safest form of transport and the well known adage that you're more likely to get hurt driving to the airport is true. However private flying is a different story. It is not safer than driving a car. Depending on how you measure it, stats from the USA show that, per mile travelled, private flying is about 10 times more dangerous than driving. If you use hours instead of miles flying is about 20 times more dangerous per hour than driving. This is the average over all non-commercial flights. So don't fool yourself that flying is as safe as driving a car....but it's better than a motorcycle (26 times worse than a car per mile). Recognise the risks, do your best to reduce them, fly safe!
  12. Perhaps I am a bit cynical. This is the first time (I think?) the RAA have come out with a preliminary accident report like this, so soon after an accident, and as an email to members...despite the number of accidents that have happened recently. It does not pinpoint any safety concerns. It is, however, quick to point out that the engine was running at impact. So it looked like the motivation for the email was attempting to quell any concern that the accident was a fatality caused by a Jabiru engine failure. Not that there's anything wrong with that. I'm happy if the RAA helps out Jabiru like that (if that's what happened). I just hope this wasn't a one-off report for the benefit of an aircraft company rather than the first of many reports to benefit members.
  13. Interestingly the NRMA is now bribing their members to vote in board elections with a chance to win a new car. You'd get 10,000 votes in RAA board elections if you could win a plane!
  14. Of necessity, in any organisation or Government, the members elect their representatives to make decisions on their behalf. Members then decide, after the fact, if the representative has done a good or crap job and vote accordingly at the next election. I voted for DonR because I trust him to make decisions that are in the best interests of RAAus. It may be that my trust is misplaced and if so I'll vote against him next time. I do NOT want an email from him before every board meeting asking me (and his other members) how he should vote on a particular issue. How would I know which way to vote? I haven't been involved in the discussions nor can I know all the facts. I don't want to read a 100 pages of information, financials and budgets to see if a certain decision is affordable or not, or if it fits in with the organisation's strategic plans or goals. My life is busy enough. But I can't make an informed decision without knowing all the above. So I'm happy to leave it to the guy who represents me and has read all this stuff (hopefully). We do however need to be kept informed on the performance and solvency of our organisation. If the Board are making a complete dog's breakfast of things we need to know about it and we have the right to call a special meeting at any time, in between elections, and sack the lot of them if we wanted to.
  15. On the subject of regional representation... Thinking through it, I too think that the makeup of the RAAus board should be purely skills based rather than regionally based. Being basically a national aviation regulator operating under national laws I'm struggling to think of any way that they could favour a certain state or region with what they do. If for example a SE Qld power-block developed in a skills based board is there any way they could favour Qld pilots? Is there any way a board could funnel money into a certain region and what possible advantage could that be?
  16. The demo plane here in Oz crashed too didn't it?
  17. I'm betting the price will be approaching the cost of the rest of the aircraft, but EFI and intercooled turbo are mature technologies. Despite the much higher parts count, modern turbo efi engines are more reliable and efficient than the old carburetted engines in ground based vehicles. More to go wrong does not necessarily translate into less reliable (and rarely does these days). More parts are often needed to increase reliability.
  18. Using local time instead of Zulu would be a bit like using AGL instead of AMSL for height. Local time and AGL are a constantly moving target while Zulu and AMSL stay the same. Stick to the standard and everybody is on the same page....no confusion.
  19. I was taught: "If it's written down it's true!"
  20. While it's all very well to say there are no safety issues with the hardware and therefore make no comment on a death, seeing that the majority of accidents are the result of human factors I believe it's worth giving us all a wake-up call now and then. This unfortunately sometimes makes an example of someone that has died, but it is always more real for me to learn that people can die from fuel mismanagement, or a stall/spin, or flying into IMC, or low level flying or whatever, and makes me more vigilant. Human factors are something we should have learnt and all be aware of....but since we are human we need a reminder of our humanity now and then. I appreciate that the law at present prevents it, but we really need to know the human factors as well as the aircraft issues that lead to an accident so we can learn. I've said it before....if I go in, especially if it's from my own stupidity, feel free to speculate and learn from my mistake. There was a ppl pilot around here that died in a crash from a wire strike. I didn't know him at all, but heard time after time from pilots who knew him, or even from non-pilots that had gone for a ride with him, that he liked low flying. Now and then we all need a wake-up call.
  21. I dunno Maj. Found a USB memory stick washed up on a Sunshine coast beach (in the water) earlier this year. Washed it in fresh water, gave it a week to dry out, and works fine. I was hoping to find some interesting files or photos....but instead got a couple of movies I hadn't seen With a bit of luck memory cards should last a little while in the water.
  22. Going back to the actual Morgan design....what do others (including builders) think of pop rivets going into FRP ribs? Is the fibreglass strong enough to hold a rivet over time...especially with the uneven temperature expansion/contraction of the metal skin over the plastic ribs? Also, the stabilator appears to have all the FRP ribs epoxied to a single metal torque tube (is that the right term?). Again, it seems to me in the long term that epoxy might lose adhesion to the metal due to uneven expansion/contraction. Of all the joints in a plane they are the ones I would most hate to fail. Comments?
  23. I would never buy an aircraft that didn't have proper maintenance paperwork. Not only for my own safety and peace of mind but when it comes time to sell it I need to be able to prove to the next buyer that everything is above board. Otherwise I may find myself with an unsaleable aircraft or at least take a big hit on the resale price before the next buyer is willing to take the risk.
  24. I don't know the origin of the CASA SD reports (I guess submitted voluntarily?), but I often browse through them because it is an interesting cross-section of all engine and airframe faults. The Jabs reported are mostly RAAus registered according to the notes in each report. Yes, there are rarely any other RAA style engines. One was an HKS. It's just another source of data that CASA may have taken note of in this debacle, and when you compare Jabs to other engines, even in the small samples of Jabs, there is a trend of specific faults which often caused (according to the reports) forced landings. Browsing through other engine types most faults are not catastrophic and were picked up on the ground. Comparing Lycs and Contis the Continentals seem to have more than their fair share of cracked cylinders or crankcases.
  25. Call me an idiot.... but I have just read through all the 33 pages here in the spirit of discovery. I don't own any aircraft. I admit I have a negative view of Jab engines gleaned through a lot of reading, some perhaps biased, but am always willing to be swayed by new evidence. This thread has gone on a lot of tangents. I get that CASA is like many Govt departments and has various fiefdoms within it all vying for relevance and power (after all, the relevant and the powerful are the ones who get the funding). I agree that CASA's actions are counterproductive. However, suddenly in this thread there was a time when fellow Jab owners started discussing oil usage, blow-by and various methods of modifying the engine for catching oil and preventing it going out over the aircraft. Another was having to enlarge oil feed holes to prevent wear. Now, I know that the one of the basic tenets of Recreational Aviation is the ability to experiment and modify. But really, a discussion on catching oil and enlarging oil feeds is something I'd expect to see in a discussion about a Gipsy Major engine or some first generation experimental engine rather than a mature modern technology aero engine from a reputed manufacturer. If you were me which camp would you put Jab engines in....experimental or (certified) mature technology? Secondly, I don't know what evidence CASA is basing their action on. But step back and have a look at CASA's own service difficulties and reports on piston engines for the past 5 or more years. I assume these are contributed in good faith. In amongst the heaps of reports about Lycs and Contis you will find 5-10 reports or more about Jab engines every year. Look closely at the causes of engine failures in Jabs according to failure causes for all other engines. Be honest, if you were somebody looking at those reports for the first time, can you identify a trend? Would it raise question marks in your mind that there is a specific problem? I don't know if this adds or detracts from the discussion. Feel free to flame me. I try to be balanced. One day I will decide which aero engine I will own and fly behind. Based on this thread which would you choose?
