Mandatory inspection and/or replacement of the crankcase and/or gearbox housing for ROTAX® engine types 912 iS, 915 iS, and 916 iS fuel-injected engines.

Thanks! These seem to be relatively new engines. Can you give us an idea of the manufacture dates? My 916 (SN:10001691) isn’t on the list and it’s less than two years old (would be great if the date can be looked up, but haven’t found it). 

I have a non-certified 915iS and can not find any serial numbers.  I'm confused.

Good grief, Rotax. A second grounding service bulletin in a little over a month. I am not a happy 916is owner. 

I don’t see a list for the gearbox serial numbers. Just the engine serial numbers are included.

Hi Robert...nothing was said about grounding.  That was not in the SB.

Cheers
