The NTSB's narrative final · quoted from the NTSB record
After a normal takeoff roll, the airplane lifted off the ground and immediately yawed to the left. The pilot stated he was unable to correct the yawing by applying right rudder, and said the right rudder travel was 'short and stiff.' As the airplane approached the trees, he pulled the power back and attempted to land. During the landing, the airplane's right main landing gear was sheared and the right wing and fuselage were damaged. Examination of the wreckage did not reveal any pre-impact malfunctions with the airplane. Additionally, examination of the airplane's rudder system revealed that the rudder travel was in accordance with the airplane's type certificate data sheet. After the accident, the pilot stated that the passenger was 6-feet 2-inches tall, and while he did not feel the passenger pushing on the rudder pedals, it was possible that the passenger may have had his feet on the rudder pedals. Additionally, he stated he always briefed passengers about not touching the control stick; however, he did not brief passengers about the rudder pedals.
