Yes it is, if you go back to the original question posed by the OP, he was
asking about the root cause of accidents. It is a fact (links at the end)
that Jet/turbine and piston engines have different MTFB's Of course it is
not the only factor in an accident, but engine failure is a fairly serious
matter and not normally something a pilot can do much about (assuming he is
operating the equipment by the book).

To paraphrase the report:-
The in-flight shutdown (IFSD) rate, a measure of reliability, for gas
turbine engines in large commercial aircraft is 0.5 shutdowns for every 105
hours of flight. For single-engine military jet aircraft, the IFSD rate is 2
for every 105 hours. The IFSD rate for light aircraft piston engines is
considerably worse, about 5 to 10 for every 105 hours.

Barney,

Another part of the equation is the reliability of piston engines vs
turbines....


Is it? How many piston accidents are due to engine failure? Is that a
major factor in accidents? In fatal accidents?
