An Airbus Group Defence & Space statement, concerning the black boxes of the A400M which crashed in Seville (Spain), on May 9, has led to some speculation. The Spanish investigation commission (CITAAM) in charge of the inquest confirms that there had been a power problem on three of the four engines just after take-off.
"Engines 1, 2 and 3 experienced power frozen after lift-off and did not respond to the crew’s attempts to control the power setting in the normal way, whilst engine 4 responded to throttle demands. When the power levers were set to “flight idle” in an attempt to reduce power, the power reduced but then remained at “flight idle” on the three affected engines for the remainder of the flight despite attempts by the crew to regain power."
According to the preliminary analyses of the Digital Flight Data Recorder and Cockpit Voice Recorder, the aircraft’s other systems "functioned normally" and no other anomalies were identified during the flight. Airbus Group Defence and Space have not added any other recommendations to those of the 19 May warning note, which asked A400M operators to inspect the aircraft engines’ control systems following the discovery of a potential anomaly on the engines’ management computer system.
