Mandatory Service Bulletin: Inspection and/or replacement of expansion tank assy. for ROTAX® 912, 914, 912 i, 915 i and 916 i (Series) Aircraft Engines

Thank you, Alan.  Please post updates when you have them. I think I will call Lockwood and send them my photos.  Mike

Hi Alan, was your engine serial number within the ranges that were possibly affected?  My serial number is 9144585--not in the ranges on the SB--I believe that means that the SB does not apply to my engine.  I spoke with Dean at Lockwood and he said he would look at the photos even though my engine appears to be exempt from the SB.

Yes, my S/N is 10000912. 

Alan
