A few possible causes of the engine failure have been analyzed based on examination of the wreckage, the history of the airplane and analysis of the airplane technical documentation.
A mechanical failure of the engine. An obstruction of the engine air intake.
A failure of the ECU or of one of its crucial accessories (loom, primary sensor …) A failure of the fuel system to properly feed the injection system (Main fuel pump, main fuel pump relay …). A failure of the electrical source to feed the ECU and the fuel pump
An inadvertent switching OFF of one engine control switch (Master switch, ECU switch …).
The above cause has been categorized as probable for the following reasons:
The engine failure occurred precisely at a stage of the flight when the pilot should retract the landing gear and the analysis of the instrument panel ergonomics shows that an inadvertent switching of the Master switch or the ECU switch is likely to occur when the pilot tries to reach the landing gear switch.
The airplane most probably took off at its maximum take off weight or beyond with the consequence that the airplane would stall at a higher speed than defined in the Flight Manual.
