After takeoff, the airplane yawed left. The pilot found the right rudder stiff and could not correct. On landing, the right main gear sheared and the wing and fuselage were damaged. Examination showed no pre-impact malfunctions, and rudder travel met specifications. The pilot mentioned a tall passenger who might have placed feet on rudder pedals.

Accident Sequence

During the takeoff roll, the airplane lifted off normally. Immediately after becoming airborne, the airplane yawed to the left. The pilot attempted to correct the yaw by applying right rudder but reported that the right rudder pedal travel was 'short and stiff' and he was unable to counteract the yaw. As the airplane approached trees, the pilot reduced power and attempted to land. Upon touchdown, the right main landing gear was sheared off, and the right wing and fuselage sustained damage.

Examination Findings

Post-accident examination of the wreckage revealed no evidence of any pre-impact malfunctions. Specifically, the rudder system was inspected and found to have travel within the limits specified in the airplane's type certificate data sheet. No mechanical anomalies were identified.

Pilot Statement

After the accident, the pilot stated that the passenger was 6 feet 2 inches tall. While the pilot did not feel the passenger pushing on the rudder pedals, he acknowledged it was possible that the passenger may have had his feet on the rudder pedals. The pilot further stated that he always briefed passengers not to touch the control stick, but he did not brief them about the rudder pedals.
