One I know of a steel oil fitting cracked in one (chute pull resulted). After a complete loss of oil the engine seized.
I cannot think of a second one where the SC was causal. I do know of one pulled the chute which there is some reason to believe there were pilot operational issues involved.
I know of several that have run for a long time and the owner is quite happy with it.
As others have said, we have over a million posts on the member side that is cheap to access and search. In addition we have perks for things like databases that pay for the dues many times over making COPA the best value in Cirrus aviation.
But in general you won’t get a lot of good insights on the guest column.
