Small piston airplane accidents in 2001 through 2005 attributed by the NTSB to engine failure, by hours (top) and years (bottom) since engine overhaul.
These are only statistics, which as always can be fudged. I would have thought it is pretty obvious though that by spending money on an engine overhaul doesn't automatically guarantee a smooth road ahead.
I realise this is a subject in itself, and probably more orientated at the engineering fraternity. I think it important that pilot's are aware of what they are flying though.
Having said that....... What percentage of aircraft accidents are REALLY due to an engine issue. I would have thought SFA....
IME at least.
I believe the answer to my earlier question was:
Five times more likely in the first 50 hrs TSO.
