Synopsis:
On 14 August 2022, the AAII was notified of an accident of Hawker Hurricane Mk IV (hereinafter the “Hurricane”) during an aerial public event “Cheb Airshow 2022” (hereinafter the “Flying Display”). The pilot was a display pilot in the Flying Display programme. During the performance, after a pass towards RWY 23, he continued an aerobatic manoeuvre by a steep climb in the runway axis with transition to a turn with a great roll during which he started descending. During the descending manoeuvre, he tightened a turn, which resulted in asymmetrical flow separation on the wing. In the critical situation, the pilot attempted a counter-manoeuvre to take the aircraft from the steep turn position, but as the altitude above the ground was too low, the aircraft crashed against the ground. The pilot died. The aircraft was destroyed.
The cause of the accident was the pilot’s attempt to make a vertical manoeuvre to quickly reverse the flight direction using a sharp and steep descending turn in a small space when the aircraft stalled and started autorotating. Given the steep aircraft position, the altitude was not sufficient for recovery which the pilot attempted. As a result, the aircraft crash against the ground.
Factors that contributed to the occurrence of the accident:
- Resolving the issue with fastening of safety seat belts;
- Resolving the undercarriage state during the flight before the performance;
- Change in the set of presented manoeuvres after the start of the performance.
