Incident Description
During the preflight inspection, the pilot added a quart of engine oil. Shortly after liftoff, the oil access door on the cowling came open. The pilot elected to continue the takeoff on the 3,100-foot runway due to a concern that he did not have enough runway remaining to stop.
Witness Observations
Witnesses observed the airplane turn to the left, enter a steep descent, and impact the ground.
Pilot Statement
The pilot stated that he 'must have became fixated on the flopping door.'
Engine Examination
Examination of the engine did not reveal evidence of any pre-impact mechanical discrepancies that would have resulted in a power loss.
Investigation Findings
The investigation determined that the pilot's decision to continue the takeoff after the oil access door opened was influenced by his concern about insufficient runway remaining. The pilot's fixation on the door likely diverted his attention from flying the aircraft, leading to loss of control.
