And the evidence to Haddon-Cave included reference to Airworthiness Review Team reports by the RAF Director of Flight Safety. That of August 1992, on Chinook, criticised Boeing for not understanding how to act as a Design Authority. Two years later, Chinook ZD576 crashed with a FADEC controlled by Safety Critical Software which had not been certified. Nor did the instructions to aircrew describe adequately its operation.
