Another Service Bulletin from Rotax. This one for the expansion tank on both the 912iS and the 912ULS engines. The non-certified SB downloads and includes all of the serial numbers but refers to the certified SB for full information and I can't get it to download. The date on the SB is 12/19 so they must have just released it. It is an inspect/replace SB but without the certified SB I'm not sure what the issue is.
