On 9 May 2015, Airbus A400M Atlas MSN023 crashed near Seville, Spain, during its first pre-delivery test flight, killing four of its six Airbus Defence and Space crew members and seriously injuring two. The aircraft was intended for delivery to Turkey and was one of only 12 A400Ms delivered from 174 ordered at the time. After takeoff, engines one, two, and three failed to respond normally to power commands; the aircraft struck an electricity pylon while attempting an emergency landing. Spain suspended Airbus test flights, San Pablo Airport closed temporarily, and the United Kingdom, Germany, Malaysia, France, and Turkey paused or restricted A400M operations.
Airbus Chief Strategy Officer Marwan Lahoud said on 29 May that incorrectly installed engine-control software caused the crash, while Airbus executive Fabrice Bregier acknowledged a possible weakness in aircraft testing or procedure implementation. Investigators examined a scenario in which torque-calibration data for three engines was accidentally erased during software installation, preventing their full-authority digital engine controls from operating correctly. On 19 May, Airbus ordered one-time electronic-control-unit checks across the fleet and added procedures for engine or ECU replacement. A Spanish military investigation agency led the inquiry, with France’s BEAD extracting recorder data. Flight suspensions were gradually lifted from June through July 2015, while government monitors criticized Airbus for lacking an integrated approach to production, development, and retrofits.
