engine identification question

Ask for the logs from the seller. Better yet, get a thorough pre buy inspection done by a professional.  Those type of basic questions should be readily answered. 

Hi Timothy,

The problem is that the seller does not have any precise doc about the engine and no logs at all. The aircraft Identification sheet says Rotax 912 ULSFR, nothing more.

I just wanted to get a little idea about the engine before engaging any money.

Do you know how much such a pre buy inspection will cost?

Hello Manfred

interesting problem.  The 912 ULSFR is a special french version of the 100 HP experimental Rotax.  (the letters UL are for experimental only and the S is for the 100 HP. The FR is for the French release with different data sheet) The only differences were it had a different data sheet and restrictions on RPM for normal operation to comply with French regulations at the time.  

A look at the only data I could find show it was sold in France in 2006 and installed in a French aircraft that was not the Zenair.  This suggests it has a history you will not be able to verify.  Without any log books to check adjust your price accordingly.  This engine would have  had blue valve covers and a serial tag with a blue background.  

Cheers

Hi Rotax Wizard,

Thanks a lot for your answer!

The engine has blue valve covers Indeed and the serial tag corresponds, too!

The zenair was built from a kit in 2013 by a French company named Grimm.

Its probably this company who put this engine into the zenair, as the seller tells me that he purchased the plane from Grimm with the engine.

Any chance to get more info through the name Grimm?

Thanks again for your help!!!

 best regards

Manfred
