Talking lifetime of relays, cb's?
Everything on any plane built needs fixing from time to time. It is up to well trained pilots and mechanics to spot problems and get them fixed PROPERLY>
I have seen enough to say: it sure seems that the pilots and mechanics at this airline were not up to snuff on the systems involved. it also seems the airline wasn't up to snuff on a boeing/douglas recommendation. it also seems that the airline did not train pilots in takeoff/departure stall recognition and recovery.
now, is anyone out there really going to argue the above?
I don't want to seem calous over the loss of life, but well maintained airplanes with well trained pilots rarely crash!
