I must be slow today, I don't know who youa re, send me a private message. And you are of course right. Only a complete investigation, which takes a while will uncover the truth. I remember once when we had a plane come out of a mod and the gear hande, when raised, caused a pressurization problem. The mechs in NY found mis-wiring. You never know. I am sure the investigators will get to the root of the problem soon enough, but given the previous comments about the accident in another forum, I doubt it was wiring.
