it was getting over 200 hrs a year that could be a red flag.


I flew my plane 275 hours the first year I had her. I'm thinking a red flag should go up on the order of 500 or more. There are simply too many pilots who fly their airplane often, particularly 150s.

And the 'official' TBO, calendar-wise is 12 years. My engine has just passed 10 years. Continuous operation overrides the 12 year suggestion in my book!

Everything else is spot on.
