Jabiru engine failures
I'm confused and also not surprised.
The latest version of this instrument was released on Saturday December 20th saying that it needed to go before Parliament, however would be enforced by Christmas, but we all know parliament doesn't sit till late January. It has been suggested to me that CASA do not have the power to enforce such actions without parliamentary approval.
I then check the website today and find out that the instrument came into effect on 23rd December (practically Christmas Eve as we all predicted).
Does anyone else remember the reference to parliament? I should have screen captured it, doh
How is an owner expected to know this and not break the law? I've seen no emails about it, nothing from CASA, zip. Is an owner / operator expected to check the latest media release section on the CASA website considering this instrument bans Jabirus operating into Bankstown for example. Too bad if you landed there and didn't know !

It's in force and remains in force unless:
- it's not tabled in parliament when it has to be - months away - or
- it's disallowed - unlikely.
Nobody knows what the combination of regulations, orders, exemptions, directions, MOSs etc means anymore.

Here you go squawkie, From the 20th Dec Explanatory Statement:
I did save it.
Legislative Instruments Act
Under paragraph 98 (5A) (a) of the Act, regulations made for that provision may empower CASA to
issue instruments in relation to matters affecting the safe navigation and operation of aircraft. Under
subsection 98 (5AA) of the Act, an instrument issued under paragraph 98 (5A) (a) is a legislative
instrument if expressed to apply in relation to a class of persons or aircraft.
The instrument applies to classes of persons and aircraft. The instrument is, therefore, a legislative
instrument, subject to registration, and tabling and disallowance in the Parliament, under sections 24,
and 38 and 42, of the Legislative Instruments Act 2003.

Head in the sand.
Apparently Jabiru have been aware of the issue with their engines for years and have chosen to ignore it.. Looking at their website there is no acknowledgment of what has been imposed by CASA on their engines. I guess 'ignorance is bliss'..

They havent ignored it, but brought in a heap of changes which have helped cloud the real cause. Some rushed and ill thought out. This might spawn a few more.
Contrary to what many home engineers think, it osnt an easy fix.
Some attitudes at the company sure havent helped.
CASA have worked with unverified raw data, even the source, RAA, think it is badly misrepresented. It applies to all aircraft even those in experimental catagory which is plain wrong.
Based upon comparisons to competitor brand, with no acceptable failire rate established. Some engines limited dont even have comparative engine offering.
There needs to be improvements but tis isnt the way to make it happen.

It's an interesting approach by CASA.
If I were to operate a GA registered Jabiru powered aircraft, I would have no way of knowing that this has even happened. I happened to check the CASA Media Release section and noticed that this instrument came into effect on 23rd of December, but nothing has been sent out to operators by CASA so one could be blissfully unaware of this whole thing and then "illegally" fly into one of the prohibited areas or take flight without a passenger waiver in place.

How is an inflight breakup related to engine problems ? One positive thing Jabirus are noted for is their structual strength. This is the first inflight breakup of a Jab that I've ever heard of.
Once when I visited Bundaberg I was fortunate enough to see them being structually tested to destruction in big hydraulic presses with gauges all over the place.Jabaru would be one of the few companies that go to the trouble and expense to thoroughly test aircraft sold in this class.

This is well worth a watch if you are interested in the plight of Jabiru. It gets serious at the 11 minute mark. Makes you realise that you need your ducks in a row if you are intending to face such an inquiry.

Theres some porkies being submitted there - pretty serious place to discuss details you arent sure of
Good to see CASA under pressure for damage it has inflicted on Aust aviation businesses and aircraft owners

A bit more fun for the outsider, though, who can be a bit more adventurous if well prepared and briefed.
The ATSB have weighed in to the debate;
Engine failures and malfunctions in light aeroplanes 2009 - 2014

This graph would suggest the VH-registered maintenance regime is seriously inferior to that overseen by RAAus...
Perhaps the regulator of regulators should prevent one of the regulators from regulating above populated areas and without the regulated indemnifying the regulator from irregularities and failures in regulation...?

Andy…..From the ground, the numbers do not stack up. ATSB do not have the REAL data. Even from anecdotal evidence I can tell that.
The secret here is knowing if your data looks and feels right to ensure the collective sensors are fully functional.
I put it to you that the reporting culture in the VH arena is far better (not perfect by any means) that it s in the RAA area.

It appears you are reading that graph incorrectly perhaps.
Very few RA-Aus aircraft have Lycoming and Continental engines and likewise fewer GA aircraft have Rotax engines so the numbers do appear to stack up correctly in that graph. The heights of the bars appear to be largely meaningless.
16 Jab failures in GA.
114 Jab failures in RA-Aus.
The ratios seem about correct.
To Jabba's point, as for whether the total numbers are too high and should or shouldn't include certain events for example, remains to be seen.
Taking these statistics to use for comparative purposes between manufacturers seems to be the go versus trying to analyze the validity of the total numbers, under the assumption that all injustices are applied equally.

Graph comes from ATSB website from link in spinex's post directly above.
Whether or not the data is bullshďt or real doesn't really make the regulator's position a happy one, either way...

The height of the bar is the rate per 10,000 hours. So lycomings at 1.2 (VH), and RAA rego contis (but such low numbers that you can't really tell.
I wonder if the conti numbers only include things like the C85 in the super cub.
