My Jabiru must have ABS, as there is no way it will ever lock up!

sorry this link http://www.dailyadvertiser.com.au/multimedia/41729/584773/picture-oscar-colman.aspx?Start=15&page=1

This link shows a clearer picture, so very sad, thoughts go out to family and friends, Tom http://www.dailyadvertiser.com.au/news/local/news/general/man-dies-in-plane-crash/2584881.aspx

Thanks OME good to hear about things we should look out for. Tom

the attachment at the wing root? or wing /strut attach? if the wing root, does the attachment lug move or does it seem loose in the lug? just curious . Tom

Maj,Yes that is why I thought I would ask about the interest for a 912 mount perhaps I could make one up if there is enough interest. A friend of mine is just converting his J200 now with a 912S. Tom

You are correct it is a good plane, I also have a J400 and am very happy with it, but mine does have a 914 in it what an impressive performer!

What model Jab do you have, why a 914?

Just out of interest, how many out there would be interested in a 912 engine mount for the Jabiru?

It is up to Jabiru to address the serious issue, we can talk all we want but if the manufacturer has deaf ears, then we are a little limited as to what we can actually change to improve the engine particularly in a school invironment! Jabiru if you read these forums, time to act! Tom

Hey, just an aside and to add a little lighthearted post, probably a little off topic, I had a mazda rotary one time that, due to a faulty radiator cap, did a water seal. Just for fun, a mate and I decided to get it going again and drive it till it stopped ,well we drove and drove and drove, ended up driving it back home, mind you is was not putting out much power and running real sick, but got us home. Where upon we decided to cool it down with the hose and I kid you not, it sizzled more than 10 minutes with the hose on it :-))) Surprised both of us that we could not kill it, we really tried hard! Jabiru make great aeroplanes, affordable and strong, now if they can get their engines more bullet proof, it would make us all happy. It may mean the price for engines may have to rise, let them get the engineering right and fully tested on the test bench or factory test plane before making it available to the public, Time to rise to the occasion Jabiru!

David, yes you are correct in that the photo I posted shows very mild detonation, just wanted to put it up so that others can see the result of detonation.Yes the ring lands were close to broken and the rings were jammed in. If the Jabirus are detonating then there should be evidence of it. I am not saying they are not but there should be telltale signs. Tom

here it is, sorry a little finger trouble uploading

I don't really think the Jab engine is detonating, I have attached a photo of a piston that has experienced detonation,(on take off) as you can see it is destructive, any Jab pistons out there with similar damage?

Yes the rotax Jabiru is definitely the go. The Jabiru airframe is a strong low maintenance airframe coupled with the reliable low maintenance Rotax it really is a good machine. Tom

SF, no worries I just read your other post, seems a rare occurrence having a gudgeon circlip dislodge. how many hours? Tom

Sunrayisa Flyer, was it a thru bolt that failed on you too? Same type of engine, ie hydraulic lifter with the spacers under the barrels? how many hours since new or o/h? was the cylinder base cracked as well? just want to see if there is a pattern to these failures. Good you got it down safely. Tom

How can fitting hydraulic lifters break thru bolts?

I could be wrong but yes jetjr is right in saying it is a relatively recent problem (thru bolts) early Jab engines did not have this problem, Jabiru need to go back and see what they changed (gosh that would take forever) that now causes the thru bolts to break. Eg have they changed the bolt manufacturer, the timing, the mixture? or something else that is causing this problem. I believe they are claiming a few more horsepower over the older 2200 engines is this adding to the problem? just my thoughts Regards Tom

Great job on the training side of things, so good no injuries, suggest when you get it repaired ask Jabiru to make up a Rotax mount for it, might make them think about finally fixing the ongoing problem. Fantastic aeroplane with a rotax.

Thanks Mike, I have received it, will suit my purposes perfectly, Thank you

Hi Mike, not sure how to PM so here is my address [email protected] I very much appreciate your help in this matter, cheers Tom

Mike,It has the aeropower engine Regards Tom

Sue , do you happen to have a copy of CA 21 flight manual, I recently purchased a skyfox which unfortunately has the flight manual missing Regards Tom

I fail to see how a sticky intake valve would prevent the engine producing enough power for at least level flight. Tom
