Anyone know if the new Rotax AD effective Nov.8th applies to our RV-12 912ULS ?
This is an amendment to AD 2002-16-26 (crankcase crack inspection) that now includes 912(S) series engines....does ULS mean it is an (S) series engine? This could be real UGLY!

does ULS mean it is an (S) series engine?

The "S" denotes a 100 hp engine. The "non-S" is the 80 hp engine.

There has been a similar service bulletin out there (SB-912-029-UL) since November '06 regarding checking the crankcase for cracks on the 912ULS. I would think that the serial # range would be pre-RV12. My engine came from the second batch of 25 that Vans shipped and was well beyond the serial #s covered by the SB.

But, be sure to check your serial #.

The 912ULS is the non-certified version of the 912S.

you are experimental and not subject to AD's...probably a good idea to be concerned just the same. The 912ULS will be addressed by company Service Bulletins as mentioned above.
