But as he didn't appear to have used it, is it relevant pertaining to the accident.
As I mentioned on the other thread, this is not about the seat use
per se but the organization and culture surrounding the accident. Following an accident, the regulatory and supporting documentary evidence are key pieces of the puzzle in establishing how the aircraft was flown and operated. What the CAA are saying here is that enthusiasm and good intentions are no substitute for regulation and control. But as others have noted, what the CAA have actually revealed is that for these omissions and oversights to have been quite as systematic across vintage FJ operations as they appear to be, nobody at the CAA was paying attention until 2 tragic accidents occurred in a short space of time.
