American Champion Aircraft 7GCBC N139PC accident near Montgomery, New York

Probable cause

The pilot’s failure to maintain directional control during landing, resulting in a ground loop and structural damage to the airframe.

NTSB analysis

The pilot reported that he was landing with the tailwheel-equipped airplane in calm wind. Upon touchdown, the airplane veered to the right despite attempts to keep it tracking straight with left brake inputs. The airplane ground looped to the right and came to rest in the grass, adjacent to the runway. The Federal Aviation Administration inspector who examined the wreckage after the accident reported that there was substantial damage to the fuselage near the main landing gear strut attachment points and near the tailwheel. Examination of the wheel brakes, tires, and flight controls showed no indication of a preexisting mechanical malfunction or failure, nor did the pilot report one.
