Of course my experience is mostly from the 80s when they were killing pretty regularly.
I flew MU 2Bs back in the late 60s when they were marketed by Mooney. I was a flight Instructor for the Cessna/Mooney dealer in Orlando. We only had one incident where one of those Garret grenades locked up on the boss fortunately he was at altitude and not on takeoff or approach. I always thought it was a great handling airplane and wondered why all the accidents started happening. Did anyone ever figure out what the problem was?
