Round Engines Posted November 24, 2016 Share Posted November 24, 2016 Another day, another jabiru engine failure. A mate contacted me to tell me that his Jabiru engine failed while flying. A piston left the engine then it seized. Lucky to land unscathed in a freshly ploughed field somewhere north of Perth. 3 Link to comment Share on other sites More sharing options...

facthunter Posted November 25, 2016 Share Posted November 25, 2016 Oh well the problem will be over soon. There will be no jab engines flying. Is that what everybody wants? I am sure the current owners would like facts and details. Pistons don't leave engines generally, and I'd be very interested as to just HOW that could happen, and does a jab engine fail every day? Really? Nev 1 9 Link to comment Share on other sites More sharing options...
JEM Posted November 25, 2016 Share Posted November 25, 2016 Lets wait until the full details of the cause are available. Cause could be nothing to do with the engine itself. (oil loss etc) 8 Link to comment Share on other sites More sharing options...

ave8rr Posted November 25, 2016 Share Posted November 25, 2016 Lets wait until the full details of the cause are available. Cause could be nothing to do with the engine itself. (oil loss etc) Problem is that the cause will probably not be published. Need ATSB to investigate for this to happen... Link to comment Share on other sites More sharing options...
facthunter Posted November 25, 2016 Share Posted November 25, 2016 It is unlikely the engine would be examined by ATSB as there was no loss of life, and they use their resources carefully.. Under the circumstances if it is the later engine particularly, it would be of some interest to know exactly what happened. Nev Link to comment Share on other sites More sharing options...

DrZoos Posted November 25, 2016 Share Posted November 25, 2016 Thanks for the heads up, but let's all wait n see. If it is at 261 and no apparent reason that won't be good for anyone. Link to comment Share on other sites More sharing options...

Geoff13 Posted November 25, 2016 Share Posted November 25, 2016 Pistons don't leave engines generally, and I'd be very interested as to just HOW that could happen, I have seen it happen on 3 separate occasions. Admittedly not on aero engines. I have had one engine that you could put your head in the hole that the piston had punched through the block on the way out. It also poked a hole through a Bonnet and took out a steer tyre at the same time. Link to comment Share on other sites More sharing options...

ozbear Posted November 25, 2016 Share Posted November 25, 2016 You would think there would have been a catastrophic failure for a piston to be ejected such as a broken Conrod this isn't the usual type of failure I would be very interested in what caused this.

geoffreywh Posted November 25, 2016 Share Posted November 25, 2016 even a broken conrod is not going to let a piston out. How about broken cylinder ? Cylinder off, then the piston is set free! At least thru, bolts would have been ok? Link to comment Share on other sites More sharing options...
JEM Posted November 25, 2016 Share Posted November 25, 2016 Riley, how come my engine has gone 15 years now and never missed a beat in the air? My Jabiru 2200 engine has been running happily since 2003. A very reliable engine 4 1 Link to comment Share on other sites More sharing options...
facthunter Posted November 25, 2016 Share Posted November 25, 2016 Rods may come out the side and blocks may break. Pistons are not able to do much but go up and down unless something very drastic has happened. Pistons can break into parts and then the rod does a lot of damage. The block (or cylinder) guides the piston and is substantially built. Piston speeds are around 40 MPH max. Hardly having a lot of energy they weigh about 700 grams.
