Wondering if I need to worry about this or not? Thanks for any input.
Since Rotax bothered to issue the SB it implys that it is possible, but the company airplane that we have that has an engine that was listed, has always passed the test and it has now accumulated enough hrs (1000 if I remember the SB correctly) that the test is no longer required.
I guess the question to ask would be "what is Rotax willing to do to cover the repair if a crack is detected during the 1000 hr period" I don not know the answer.
