Incident Summary
During the landing rollout on runway 09, the aircraft departed the right side of the runway and nosed over. The pilot shut down the aircraft, and both the pilot and passenger egressed from the inverted airplane.
Examination
Post-incident inspection revealed a 300-foot skid mark left by the left main landing gear and a 150-foot skid mark left by the right main landing gear. The aircraft sustained substantial damage to the propeller, rudder, and left wing.
Sequence of Events
As the aircraft decelerated on the runway, the pilot applied rudder to align the aircraft with the centerline. During this maneuver, the foot of the occupant in the front seat pressed the opposite brake pedal, which caused the aircraft to react slowly. The harder the pilot applied rudder, the more force was applied to the opposite brake. When the aircraft began to depart the runway, the pilot applied left brake. Inertia then nosed the aircraft over.
