Default Engine Failures per Million Hours

Jamie,

You aren't going to like this... In about 140,000 hours
of flying *at* BPPP (BPPP.org) clinics, there have been
7 engine failures. Real stuff busting, not running out
of fuel or anything like that. IO470s, 520s and 550s.
Shiny looking airplanes. Fortunately, only one with
injuries.

You wouldn't have to figure this in ppm!

I personally was involved in one of them where a 470
threw a rod on downwind. Fortuantely there was a spare engine. It's
all made me more conservative.
