The Ministry of Defence has repeatedly dismissed claims that the Mull crash could have been caused by software. Its argument, in part, is that Chinooks have been flying safely all over the world while fitted with the “Fadec” engine control system.
But Computer Weekly has learned that the contractors responsible for the Fadec software, who had previously resisted making code changes requested by the MoD’s IT experts at Boscombe Down, modified the software after the crash on the Mull of Kintyre – at their own expense.
