@xavierde this should compensate average differences in utilization amongst aircraft types.
Would it still have to be corrected for length of the production run? ie is the 3328 TT average for Mooneys, which have been in production for 71 years, directly comparable to the 1601 hrs TT of DA40’s which have been in production for only 27 years?

Mooneys are mostly privately owned, rarely club airplanes, hence the relatively low TT most of them have.
Antonio one question in this aspect of the timespan of the accidents is: are the pilot skills different today than 70 years ago? Another aspect regards instrumentation: with glass cockpit, GPS and things like AOA indicators there’s much more aid to obtain from the panel than like 50 or even 70 years ago.
So if the accident rate lowered over the years due to better training or equipment, then the accident rates of old planes are not comparable over the whole time.
Could a good proxy for aircraft utilization be to crawl aircraft listings and extract total time?
Summing up the total time for each model listed for sale would give the total flying hours of that “fleet”.
This is a great idea, love the creativity!
