At the time of the crash, new FADEC (Full Authority Digital Engine Control) equipment was being integrated onto all RAF Chinooks, as part of an upgrade from the Chinook HC.1 standard to the newer Chinook HC.2 variant. The Ministry of Defence was given a £3 million settlement from Textron, the manufacturers of the system, after a ground-test of the FADEC systems on a Chinook in 1989 resulted in severe airframe damage. Contractors, including Textron, had agreed that FADEC had been the cause of the 1989 incident and that the system needed to be redesigned.
