| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that during 'the mid stage of the takeoff roll...I experienced one or two asym[m]etrical surges that caused the plane to yaw to the right.' The pilot stated he corrected these with nosewheel steering (the pilot's operating handbook states not to use nosewheel steering during takeoff). The pilot stated, 'As I approached rotation speed, there was a strong yaw to the right....I believed...the nosewheel [had deflected]...full right....I then pulled back on the yoke to pull the nosewheel off....I became airborne...I heard the stall warning. The plane then veered sharply to the right, going off the runway....' Post-accident examinations of the aircraft's right engine and propeller revealed no evidence of pre-impact engine or propeller mechanical malfunctions. Directional control on the ground is available in the accident aircraft via differential braking, differential power, and rudder, if nosewheel steering is not available. While the pilot reported he had recently flown the accident aircraft with another pilot (not an instructor) to 'review aircraft systems and check my pilot competencies', his last documented flight review was 6 years before the accident.
Probable Cause: The pilot's selection of an improper remedial action for an unanticipated yaw excursion during takeoff roll, resulting in the aircraft becoming airborne with inadequate airspeed and consequent loss of aircraft control.
