The numbers 1, 2 and 3 engine of the Airbus A400M that crashed on Saturday 9 May in Sevilla, Spain, experienced a power freeze immediately after take off, according to a Accident Information Transmission (AIT) issued by Airbus Defence and Space on 2 June. This AIT informs that the digital flight data recorder and CVR readouts have been successfully completed and that preliminary analysis has been conducted.
Investigators confirm that engines 1, 2 and 3 experienced a stuck power setting 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.
The aircraft crashed a short distance from Sevilla airport, hitting a power line first. Four people died in the crash, while two others were taken to hospital in serious condition. The aircraft was almost totally consumed by fire. An engine problem was suspected soon afterwards, as reported here on Airheadsfly.com.

Preliminary analyses have shown that all other aircraft systems performed normally. Accordingly, Airbus Defence and Space does not have any additional specific recommendations, other than the Alert Transmission Operator (AOT) already issued on 19 May. That AOT told all A400M operators to inspect the Electronic Control Unit (ECU) on all engines.
The problem by have been caused by incorrect installation of software during final assembly of the A400M concerned, which was destined for Turkey. Airbus Defence & Space has stated it is battling quality control issues in the A400M’s final assembly.
According to Airbus, the investigation continues and further updates will be given if significant new information becomes available.
