What happened
A local skydiving operation departed from Triengen Aerodrome in a single engine airplane carrying nine people, including one pilot and eight passengers. The flight was intended for local jumps. During the mission, at an altitude of approximately 3,000 meters, seven skydivers successfully exited the aircraft. Shortly after these jumps, the left ailerons became detached from the airframe.
Following the loss of control, the aircraft entered a steep dive. The pilot and the one remaining passenger managed to abandon the plane before impact. The aircraft subsequently struck a house within the village of Triengen. The collision resulted in the total destruction of both the aircraft and the residential structure. Despite the severity of the crash, there were no injuries and no fatalities reported among the occupants or those on the ground.
Findings
Investigations into the incident identified that the left ailerons detached while in flight. The primary factor was the failure of the aileron control cable. This cable had sustained prior damage, though the specific circumstances leading to that initial damage could not be determined by investigators.
