Roger Lee Posted April 16, 2011 Report Share Posted April 16, 2011 Hi All, Here is a new mandatory Rotax service bulletin. All the SW's are safe and most likely most of the LS's, but the new LS's within the last year will need to take a very close look at the engine serial number. It only applies to engines with serial numbers starting with 677****. Just look under the engines effected, section 1.1, at the 912ULS serial numbers. Then look at the compliance time line in section 1.5. Rotax Mandatory SB-912-058-UL.pdf Link to comment Share on other sites More sharing options...
