On June 17, 2017, after the flight, the aircraft's pilot reported a problem with the aileron control: in order to fly straight (i.e., without banking), he had to tilt the steering wheel 5° to the right, and in addition, the aircraft responded incorrectly to the rudder. The aircraft was referred for inspection. On June 18, 2017, during the inspection of the aircraft at the LS Technics Base, a tear (effectively constituting destruction) of the inner lower cable of the aileron control system in the left wing P/N 82742408-003 was detected, located between pulleys Y-194 and Y-200. The cable had practically ruptured, and the remaining strands that had not yet ruptured did not provide any tension to the cable. It was verified that the last inspection of this area of the aircraft structure had taken place 3 months earlier (March 19, 2017), and during the inspection no deterioration of the cables was found, and their tension was correct (87LBS).
Cause of aviation incident:
Fatigue destruction of the left aileron control cable in the wing.
