There is another factor here that also came into play in the AA 587 accident. In both incidents, circuit breakers were recycled prior to the failure. In the AA 587 incident, I believe it was the yaw damper breaker that was recycled prior to departure because of an intermittent failure during the preflight. In AS 261, the crew evidently recycled breakers that tripped during trim attempts.
I will go back to a post that I made several months ago about AA 587: resetting breakers should not be allowed until the cause of the either the circuit trip or intermittent problem is determined. Resetting breakers to either fix an intermittent problem or because there is no obvious cause of a trip is just asking for trouble. In fact, I also believe that the crew of SwissAir 111 also reset breakers prior to the loss of that flight. When will the aviation industry figure this out?????
