Aircraft: Cessna 140. Injuries: None. Location: Winnsboro, S.C. Aircraft damage: Substantial.
What reportedly happened: The pilot of the tailwheel-equipped airplane allowed his pilot-rated passenger to make a wheel landing. During the landing roll, the airplane drifted to the right and in response the pilot took control and attempted to correct with left rudder input. The airplane continued to veer and he applied left brake.
Both pilots braced themselves, and both inadvertently depressed both sets of brake pedals at the same time. The excessive brake pressure made the brakes lock and the airplane nosed over, resulting in substantial damage to the wings, fuselage, and vertical stabilizer.
The pilot reported there were no pre-impact mechanical anomalies with the airplane.
Probable cause: The excessive brake inputs by both pilots during the landing roll resulting in the airplane nosing over.
