"serviceable" aircraft
D246
I think it's worth repeating that the AAIB and, more recently, the MoD have acknowledged the aircraft was NOT serviceable - and named the defective system. (Quite apart from all the other problems that have been recounted here). That this is at variance with a letter received by one member claiming that the aircraft was fully serviceable is yet another example of how the MoD don't know themselves what happened, or the state of the aircraft. The obvious questions, which so far the MoD have refused to answer, is "What did you do about the defective system and how long did you know about it before the crash?"
