DWF Posted June 30, 2016 Share Posted June 30, 2016 At the eleventh hour (almost literally) CASA have reviewed the Instrument on Jabiru engines. See CASA 65/16 I looks like many (most?) Jabiru engined aircraft will now NOT need to comply with the restrictions - depending on type of operation and maintenance program. The latest newsletter from RAAus explains it. But it is still a crock! 7 Link to comment Share on other sites More sharing options...

Geoff13 Posted July 8, 2016 Share Posted July 8, 2016 Very interesting slant on it. I would hope the the call for help was not classed as an in flight failure. Link to comment Share on other sites More sharing options...
DonRamsay Posted July 8, 2016 Share Posted July 8, 2016 That presentation looked pretty accurate to me. A few minor details not quite right but overall he hit the nail on the head. Very interesting stuff about Casting and nikasil barrels. Should make owning a Jab engine a lot easier. Link to comment Share on other sites More sharing options...
jetjr Posted July 8, 2016 Share Posted July 8, 2016 Maybe, but similar was said about hydraulic lifters. The new setup does look good. Jabiru arent short on ideas to improve the engines, just seems quality, execution and testing let them down Link to comment Share on other sites More sharing options...
coljones Posted July 8, 2016 Share Posted July 8, 2016 You could say the same about RR Merlin engines. RR weren't short on ideas but the Merlin's only seemed to have a TBO of only 25 hours - sufficient, it seems, to make a mess of the Axis powers. Perhaps it was the well trained and dedicated engine fitters the allied workforces had. Mind you these engines weren't doing the circuits and bumps that seem to be the lot of Jabiru engines. 1 Link to comment Share on other sites More sharing options...
facthunter Posted July 9, 2016 Share Posted July 9, 2016 Military applications run higher output figures , hence the often reduced service life and I think the Merlin ran about 200 hours when used in a civilian application which was quite rare. Only a few countries certified them for civil use, Canada being one, as the drive to the two magnetos was not duplicated and both went through one SKEW gear which had a fairly high failure rate. Some of the views of the Berlin airlift show quite a few merlin engined aircraft arriving there with engines feathered. They were probably rushed back into service, but still the reliability of the P&W R-1830 and R-2000 twin row Wasp engines was far better.
