A poll like this tell us a great deal about what people THINK about the failure rate of a product.

Unless everyone who answered this poll all work for NTSB and conducts a thorough investigation into each crash to determine the actual cause, I personally would only give it as much credibility as it deserves.

When you have the majority of people having very rare to no CA failure, and some that experience repeated failures - plane after plane - I'm much more inclined to believe either one of two things:

1. The air where you live contains high concentration of diethylmethalglycolisopropylene, which attacks the mylar CA hinges, or...

2. Ah... never mind.
