Then I would argue that the term "overhaul" could not be used to describe or
certify the work done on the engine, no matter if part 91 or part 135. The
mechanic certified that the engine had been overhauled according to the
approved overhaul manual. "Overhaul" requires specific compliance with the
approved overhaul manual, if that manual states that in addition to the
current manual, all SBs be complied with, any other action would negate the
official definition of "overhaul". This is not saying that the engine could
have been legally repaired, rebuilt, fixed, or use any other word you want,
but it was not overhauled as the mechanic had certified.

Actually, You're Both incorrect... The only way a manufacturers SB
becomes MANDATORY for a part 91operator is thru an AD note or if it is
referenced in the TCDS. Just because Lycoming puts that statement in
the manual does not make it mandatory....

I think you're dead on TC, and many people have missed this when reading
the
ruling. In that particular case it was the overhaul manual that made
the
SB's mandatory. There was literally no way to comply with the accepted
overhaul manual without complying with the SB's. The SB's became PART
of
the overhaul manual. In all practical purposes "updates" to the manual.
