The flight crewmembers were not injured, but the aircraft received damages on the left nose part of the fuselage and the left brace strut of the nose gear was broken.
Causes:
On the grounds of the analysis made the Commission points out that the accident is most probably a result of the following cause:
Probable technical failure of the nose wheel steering of the aircraft after touchdown and the following errors made by the flight crew during the roll phase after landing at Bourgas airport:
- Not deploying spoilers to maximum position;
- Delayed in engaging reverse thrust of both engines;
- Ineffective differential braking;
- Failure to perform the emergency procedure prescribed in the FCOM in the case of malfunction of the nose wheel steering system.
