If one is going to compare statistics than you have to compare comparable numbers.
With respect to the PT6, all of the failures mentioned above would not have been counted in the 80% figure because
1) they were not in light aircraft (FAA definition is less than 6000lbs GTOW)
2) they did not result in an off airport landing or a crashed aircraft
Like most statistics the experience of one particular indivdual is likely to vary from the average of a large group. I pointed out this particular statistic (80% of all light aircraft engine failure accidents were caused by the actions/inactions of the pilot) because it reflects the facts of a large number of actual aircraft accidents over many years. How any particular pilot chooses to use this statistic.... or not, is of course up to them. I posted the information because my experience has been that most PPL's are not aware of the accident statistics and may find the information usefull.
Chuck:
in an earlier post you posted that you had a double engine failure in a Piper Navajo, due to the fuel lines being blocked. What casued the blockage ?
