Narrative:
The french fighter jet hit the wall of the airport during takeoff under unknown reasons. There was a post fire impact.
The two occupants ejected safely. The navigator (NOSA) was injured to one leg.

3.2 Causes of the event
The causes of the accident are as follows :
- the obstruction of the anemometric system of the total pressure T3 related to a long immobilization of the aircraft having allowed the installation of foreign bodies ;
- an inappropriate interpretation of the maintenance documentation and the absence of specific instructions when the aircraft are operating in dusty environments and particularly equipped with spiders or insects;
- a migration of practices in the procedure for checking instruments during the takeoff run, which does not allow the consistency of speed information to be checked;
- the weak synergy within the crew due to its composition;
- the housing conditions of the crew, which led to a state of fatigue that affected their ability to analyze;
- over-motivation to carry out the mission, linked to the two previous departures cancelled two days earlier, which led to a bias in the analysis of the crew and late decision making;
- the lack of reference points linked to the absence of a distance-to-go sign and the limited number of take-offs made in this direction on this runway, which deprived the crew of a means of alerting them to the excessive distance covered;

- the absence of mechanization of the crew in the simulator on this type of failure, which is impossible to simulate today, which has delayed the decision making process;
- an erroneous awareness of the situation associated with a focus on Jx which delayed the decision to abort takeoff;
- an incomplete analysis and communication of a precursor event, linked to the unit's cyclical organization, which prevented effective awareness of the speed consistency verification procedure;
- an atypical NOSA aeronautical curriculum, which favored a drift in the application of procedures.
