What happened
During a scheduled maintenance period at Tunis-Carthage Airport, an aircraft was undergoing engine testing under the supervision of ground engineers and mechanics. The procedure involved performing an engine run-up to verify operational performance. As the power was increased to 80% of the engine's capacity, the aircraft moved unexpectedly, overcoming the stability provided by its maintenance blocks.
This movement caused the aircraft to strike a nearby hangar. While the impact resulted in the aircraft being damaged beyond repair, there were no injuries reported during the incident.
Findings
- The incident occurred while the aircraft was stationary for maintenance purposes.
- The collision was triggered when the engine power reached 80% during the run-up.
- The primary factor in the collision was the aircraft running over its maintenance blocks.
