Accident Sequence
Approximately 1,000 feet down the runway during the takeoff roll, the airplane began to drift to the left of the runway centerline. The pilot responded by applying right rudder pedal in an attempt to correct the drift. Despite this input, the leftward drift continued and, according to the pilot, "appeared to worsen as aircraft progressed down the runway." The airplane subsequently exited the runway, struck a fence and a ditch, and then flipped over, coming to rest in an inverted position.
Pre-Takeoff and Examination
Prior to the takeoff, the taxi to the runway was uneventful, and an initial brake check performed by the pilot was normal. After the accident, an examination of the airplane's flight controls and brakes by an inspector revealed no anomalies that would have precluded normal operation.
Pilot Experience
The pilot had accumulated a total of 4 hours of flight time in the accident airplane at the time of the event.
