What happened
On 28 June 2023, a Pilatus PC-6/B2-H4, registered as EC-LQH, was performing a visual flight rules (VFR) operation at Příbram airport (LKPM) in the Czech Republic. During the landing phase on runway 24R, the pilot encountered crosswind conditions that led to a loss of directional control. As the aircraft veered toward the right, the left wing dropped toward the ground.
The investigation
The investigation established that during the excursion, the left balance rod, which is attached to the outer section of the left aileron, made contact with the grass. This contact resulted in the outer portion of the left aileron being torn away from the wing structure. The impact caused deformation to the wing area. There were no injuries to the pilot and no damage was reported to persons or property on the ground.
Findings
- The primary cause of the incident was the loss of directional control during a landing in crosswind conditions.
- The mechanical damage to the Pilatus PC-6/B2-H4 was specifically caused by the left balance rod catching the terrain.
