Uh ... he's flying at a flight school, so TBO - both flight and calendar time - certainly does apply to his commercially-registered aircraft in Canada!
Colonel, my humble apologies. My reference to "private" was mis-placed and not apropriate to an FTU question. Guess I should read more before opening mouth.
from his original post, DAZED stated this engine was operated "on condition". If this is the case, the Maintenance Schedule Approval will show NO hard time OR calendar time. It will show "On Condition". (But still not Fly to Failure, as some think)
If the engine was NOT on condition and still commercially operated, then I agree TBO time certainly applies (plus whatever tolerance the MSA allowed, if any) but I believe the "12 year thing" is only via an SB from the manufacturer which means it isn't mandatory, at least not in Canada. (not sure about U.S.) If I recall correctly (and my memory's not as good as it once was), both Lycoming and Continental tried to impose this limitation by way of SB's only , and that doesn't impose an airworthiness limitation, even for a comercially operated engine. ("Manufacturer's recommendations" still doesn't require an operator to comply with SB's) I'd be interested to see if this could be tied into something concrete, 'cause that would help clear things up!
Hey man, just trying to keep things lively!
