2015 Seville A400M crash - Wikipedia, the free encyclopedia
Several reports have suggested that as many as three of the aircraft’s four engines failed
during the A400M’s departure from Seville. Airbus is now examining whether the crash
was caused by new management software for the engine-fuel supply, designed to trim the
fuel tanks to permit the aircraft to fly certain military manoeuvres. There appears to have
been a trimming issue, leading to strong banking that was not recoverable and that the fuel
supply was re-established, but not quickly enough for recovery to safe flight.
Interesting, if true.
