My mechanic finally has carburetor circlips in stock, and I'm now trying to determine whether SB-912-073 applies to my plane.
I'm puzzled because SB-912-073 appears to apply only to "912 A," "912 F" and "912 S" engines. The engine identifying information in my Engine Logbook simply says "912ULS" and does not indicate that it is an A, F or S model.
I've searched online, and it appears that 912 A, F and S models all are certified engines, and that a 912 ULS engine is an entirely different model (https://en.wikipedia.org/wiki/Rotax_912#Variants) to which SB-912-073 would not apply.
My engine Serial Number is 6785876. Can this Serial Number be used to determine whether SB-912-073 applies to me?

912 ULS is indeed the UL (non-certificated) version of the 912S (100HP) engine.
Check the SB-912-073UL bulletin for applicability:
