Engine failure


Recommended Posts


I'm an owner of a Pipistrel Taurus, 150 hours of engine Flight ( belt changed at 100 hr )

3 weeks ago I've had an engine failure. Rotax mechanic's found a seize up bearing and an extreme belt tension. 

Has anyone get the same problem ?

Has anyone measured the belt tension ?

Thank you

That is really strange for at least 2 reasons: 1) the belt tensioners are not adjustable, 2) the crankshaft & bearings of the Rotax 503 are very strong. 

What oil are you using?  Are you mixing it 50:1?

Have you noticed unusual engine temperatures?

Thank you, pdrav8r

Yes,mechanic also said me that he never have seen a damage like that in 40 Years

I always use suggested oil ( don't remember the name ) at 2% misture

No unusual temperatures, only sudden propeller block
