Jabiru limitations

My response to Mr Stiff's indignation is: "Rod, you are going to bankrupt your company. You were in trouble before CASA stepped on your toes. You can jump up and down as much as you like but you aren't going to get your own way this time. Everything comes to an end and your number's up. Talking about numbers, ring Ian Bent - and be nice to him."

Hallelujah ......finally someone who can see the Forrest for the trees.

Our Cuz ‘cross the Tasman called Ornis,

He’s at last seen the light,

 

gone with CAMit, that’s right!

 

he’s gunna be pressed now to scorn us

Trying to get Rod to see anybody else's POV is like trying to get a fish to ride a bicycle... but that doesn't excuse CASA for playing a dirty game. Part of this saga has to do with internal CASA politics and to use Jab. owners and operators as cannon-fodder is an inexcusable abuse of power. The extension of the limitation to experimental aircraft is a clear contravention of CASA's own regulations; neither side is going to come out oif this looking at all good, and in the meantime, the collateral damage is already bad and could get far worse.

Why do you say that CASA is playing dirty games ? I would have thought that you guys would have been very appreciated that CASA turned a blind eye to the Jabiru engine failures that have happened in the last 18 years or so. The old excuse of maintenance surely couldn't last for ever.

Nah the reason Rod doesn't see anybody elses POV is purely because he has so much sand stuck in his ears, he cant hear anything.

• Fatal accident rate (Jabiru’s score was zero in USA); and

I found 2 tornados that had fatals due to engine problems. Typical Jabiru

So here's a company (CAMit) that's doing what some say Jabiru hasn't been doing for the last 20 years: that is research and development into design and structural problems. It has produced a range of upgrades that are being tested in service and the data gained is being used to further develop the product. And still people sneer that there's only 30 in service. Sure that's not a large number but at least the Company is doing something worthwhile to assist the industry and we poor mugs who want to fly RA. And it's 30 more than Jab produced.

 

Do you think, just maybe, CAMit deserves a bit better that. They may not have all the answers but at least they re looking and doing something positive. Ian Bent is, in my opinion, about as genuine as you can get and I think he deserves better than posts that dismiss his efforts because there's "only 30".

 

What happened to the Aussie spirit of giving a bloke a fair go?

 

To many words??

Airbus is having a pretty bad run as well.

Neither your comment or mine is relevant to this thread.

Gandalph, this is not about CAMit, it's about de-railing the outbreak of any commentary that isn't vituperative towards Jabiru. Get with the programme here!

FT ...more ULs flying in one state over there than we have here in the whole country !.....lets stick to our country and keep it simple shall we........

Id have thought if Jabiru go its going to be near impossible for CAE.

Why is that funny Dazza?

Nup, cant be right

Just some numbers manipulated by Jabiru to hide the truth!!

 

Casa have ignored it already

 

Maj is correct, this is 1400 aircraft, 96000? Hrs estimated. Over seven years, AND accident by cause.

 

thats more solid numbers than we have here.

 

For the good of all, RAA needs to deepen its database on accidents/incidents, accurate aircraft and engine version status and maintenance history.

http://flightdesign.com/files/Media/The Aviation Consumer - LSA Accidents.pdfThis is the article that will cause some headaches for CASA.

Jabiru, Skycatcher, Flight Design and Aeropro all show a zero fatal rate; Jabiru shows an accidents/registration rate 1.9 and Fight Design is 9.7 - five times as many or an increase of 500%.

 

Now 500 is a large number but fortunately what the figures really "prove" is it doesn't matter because an accident won't kill you if you fly either aircraft...

 

Hmmm.

 

Even with good data you can get the wrong answer. The police here have been persecuting drivers caught "speeding". Just 1 kph over the limit (100) and you're zapped, the argument being it's bringing the road toll down. Trouble is, this holiday season it doubled, not including three killed and one seriously injured when an Asian in a Range Rover did a U-turn in front of a logging truck/trailer just hours before the arbitrary start time. Being too slow kills? Well we know that.

 

So no, the article shouldn't cause any headaches for CASA. What will cause headaches for CASA will be one or two people who won't accept there is a problem with Jabiru engines. If there'd been less bluff and bluster perhaps CASA wouldn't have been - shall we say - heavy handed.

It is possible to take a problem engine, redesign the basics and produce a successful design. Holden did this when they bought the Buick V 6.

 

The problem with just 30 engines is you need to be dyno testing and running to destruction more than that number to lnow you have a commercial product.

 

This is doubly critical if the original problem is intermittant.

 

Unless this is done you have a consumer issue if you start making reliability claims because you are just guessing.

 

This is not an engine thread, it's about a CASA decision, now in force, which, it seems to me, quite a few people have decided to push on as usual, disregarding the Instrument.

 

The nature of non prescriptive instruments is while nothing happens nothing happens. CASA don't have to come after you.

 

However it's also like musical chairs, when the next Jab goes in, the implications and costs may be huge.

 

I'm surprised this hasn't occured to anyone.

 

For example, do you think your PL insurance company will cover you if you sign off your own children and take them up.

 

Have you even spoken to your Insurance company to advise them of the increased liability to ser what effect this will have on your premium or whether the company will even take the risk?

The RAAus tech and Ops team has been working on improving the data base for some time now. Remember all members have access to the accident and database on the RAA website...this is regularly updated by Ops, Tech and the Safety manager as required. This is a resorce we did not have two years ago, and is the direct result of the likes of myself and others making a constant noise about not having access to accident info for the education of all

But the DataBase should include total elapsed figures so one might ascertain reliability. There is probably no entry for the "Sun Moon Shine" 5 litre engine, either because it doesn't exist, not used in RAA or because there have been no events established. The current DataBase presentation won't tell me anything about the relative reliability of the SMS 5L. There are a range of engines and planes out there where there is no common knowledge of their numbers so that we can establish their reliability other than by, sometime, dubious claims by manufactures, builders or importers or by the shrill claims of various claques

Well there certainly some dubious claims by manufacturers, but that happens in many spheres of aviation. The task is big but it has to start somewhere and be followed up. We aren't good in that area. Many aren't because it is the hard part and not many gongs get awarded for diligence. Nev
