Takeoff and Initial Climb
A private pilot initiated a downwind takeoff from a 2000-foot sod runway. The airplane climbed to treetop height. According to the pilot, the airplane exhibited a tendency to roll off to the right, requiring continuous control inputs to maintain straight and level flight.
Passenger Observations
The passenger described the wings dropping alternately—first one side, then the other. This motion was consistent with a loss of lateral control during the climb.
Descent and Impact
The airplane mushed into the ground approximately 300 feet beyond the departure end of the runway. The term "mush" indicates a stalled or near-stalled flight condition with insufficient lift.
Post-Event Examination
No malfunction of the airplane was reported by the pilot or discovered during subsequent inspection. The airplane's systems and structure were found to be operating normally.
Pilot Statement
The pilot stated that he had to "fight" the airplane to keep it straight and level, suggesting significant control difficulty during the takeoff and initial climb phase.
