Accident Sequence
During the takeoff roll, the airplane deviated to the left of the runway centerline. The pilot applied right rudder input to correct the path. Subsequently, the airplane moved to the right side of the runway. When the pilot attempted to apply left rudder, the pedal would not depress. The aircraft continued off the right side of the runway and entered a ditch, resulting in an overturn.
Pilot's Observations
After the accident, the pilot noticed that the right front passenger's right foot was extended onto the right rudder pedal. In a written statement on an NTSB form, the pilot indicated that future pre-flight preparations would include instructing passengers to keep their hands and feet away from the controls.
Examination Findings
A post-accident examination of the wreckage did not reveal any pre-impact malfunctions. The engine, airframe, and flight controls were all found to be free of anomalies. No mechanical issues were identified that would have contributed to the accident.
