The private pilot had not flown the accident airplane for almost 1 year while it underwent repairs following a gear-up landing. The purpose of the accident flight was to ferry the airplane to a nearby airport to receive an annual inspection after completion of the repairs. On the morning of the accident, a mechanic taxied the airplane and performed an engine run-up; he did not note any anomalies. The pilot fueled the airplane and started the engine for the flight. Upon starting, the engine went immediately to full power, where it remained as the airplane taxied at high speed about 1,000 ft into a tree. Witnesses reported that the pilot was awake and alert after the accident; thus, there was no evidence of pilot incapacitation. Examination of the wreckage did not reveal any preimpact mechanical malfunctions or anomalies. Based on the positions of the throttle and mixture control, and the high speed taxi after engine start, it is likely that the pilot started the engine with the throttle lever accidently in the full-forward position. After the engine started, the pilot could have reduced or ceased engine power by retracting the throttle, retracting the mixture, or turning the magnetos off.
Probable Cause: The pilot's improper engine start procedure, which resulted in a loss of control on the ground and collision with a tree.
