Default Cirrus... is it time for certification review?

Average ANNUAL Fleet Accident Rates:
Cirrus: 0.85%
Late-Model 172: 1.72%

However, here's an interesting point: The C172 is used for instruction, while
the Cirrus is not. The NTSB lists none of the 20 Cirrus accidents as occurring
during instruction, while 68 of the late-model 172s are so listed.

If you eliminate the instruction accidents from the late-model 172 accidents,
the 172 rate drops to 0.59% *if* you assume the same fleet size. However, to be
an honest comparison, the fleet size would have to address only those aircraft
flown for personal pleasure or business...an almost impossible task. In any
case, the fleet rate would be higher.

From this data, I don't think the Cirrus rate stands out excessively.


How does the Cirrus rate compare to the late model 182 accident
rate, or the late model Bonanza accident rate? Those are more
likely to be used for travel, like most Cirrus planes.
