Default Engine Failures per Million Hours

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.


Actually, that's pretty good. The FAA estimate provided to a UK
investigative body was somewhere between 1 in 1000 hours to 1 in
10,000. I suspect that the sort of person who will shell out the bucks
for BPPP will also shell out for better-than-average maintenance and
newer-than-average planes.

Only thing is, I can't figure out how you guys racked up 140,000 hours.
The program has been around 25 years or so, for an average of 5600
hours a year. That's 1400 participants per year, average. Seems high.
You really get that many?

I've had one engine failure in about 2150 hours of powered flying
(about 950 of that in twins, so figure 3000+ hours of engine time) when
a component in my fuel servo rusted and plugged up the injectors. I
was IFR, 500 ft above the tops - and the bases were hiding mountains,
it being Arkansas and all. Fortunately there was a spare engine.
