Probable cause

The pilot’s loss of directional control during the landing roll and subsequent excessive brake application, which resulted in a nose-over.

Findings · 5

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot in the tailwheel-equipped airplane reported that the purpose of flight was to meet takeoff and landing requirements necessary to carry passengers. During the pilot's second landing, during the landing roll, the airplane veered right, and he attempted to correct with left rudder. The rudder input was ineffective, and he attempted to gain directional control using differential braking. However, during the brake applications, the airplane nosed over and came to rest inverted. The airplane sustained substantial damage to the horizontal stabilizer and the rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
