I have noticed that Jabiru have updated their Service Bulletins yesterday with the Aircraft Control Cable Bulletin released last month by CASA .
http://www.casa.gov.au/wcmswr/_assets/m ... 27/001.pdf
It is also on the RAA website
SB-002-15-08-2012-All-Aircraft-Control-Cables.

This affects all GA and RAA aircraft.

It clearly states that "An inspection is to be performed before next flight on all aircraft fitted with these types of cables to determine their current condition.

Cables that have a life of more than 15 years MUST BE REPLACED BEFORE NEXT FLIGHT"

Jabiru states that they don't use the exact fittings mentioned in the Bulletin but uses the same materials in a similar manner therfore it is applicable to Jabirus.

Make sure you have this inspection carried out before your next flight.

Safe Flying

Thanks, dak!

Does not make sense. How much dirt must enter to get to the washer? The oil must be clean sand/grinding paste and how does the sleeves, pistons, rings, bearings, oil pump etc look before the washer collapses :shock: :shock:

Hi
The two aircraft that suffered this fate were training aircraft at Rhino park when is had a gravel runway.
Way more than average time on a dusty gravel runway.
Maybe other parts of the engine have a higher oil flow which is the filtered, more of a cleaning effect ?
Have not heard of any other cases ?
Cheers

Thanks Len, it does make perfect sense, odds are that if one leg has got visible damage, the other will also have, even if invisible. Although I would have liked to keep the old ones. As a momento in the pub or somewhere. But rules are rules. :(

I believe especially the 4 cylinder engines used in training schools are more affected.

Interesting to note the recomendation to rather have a "cruise climb" setting, with more speed and less rate of climb to assit with cooling, and also interesting to note their recommendation that during climb higher RPM is preferrable, as it places less stress on the engine.

Its has been discovered that my Jab did not have this done. Is it normal to have the rings replaced as well as this is whats happening on my J400.

Trough bolt replacement is a must.

Keeping the engine at higher RPM (Cruise climb) not only gets you quicker to your destination, but puts less stress on the engine, as it does not "Labour" (low RPM at Wide Open Throttle (WOT)

Will also keep your CHT's cooler 8)

I dont think that this could have had an effect on the rings, but being a J400 the rings in your engine is probably a bit old, and it would make sense to replace them, as the barrels have to come off in any case. Bit silly not to do rings if the barrels are off :wink:

Dis you replace the rings on your J400? I just did mine at 370 hours and now the alternator wires burnt :shock: Now with the new rings the plane has much more ompressions and flies like a dream. Now to get the alternator and charge thing sorted. Seems I even have to get a new battery and the battery I had was only 3 months old

Not a service bulletin, but a published procedure for putting those pesky CHT probes in a better place:

After a meeting with Len at Jabiru today, I now have a very good understanding of what is required to get my Jabi flying again. Lack of communication and Lack of understanding is a B****CH. Thanks Len.... :D
