Incident Description
According to an FAA witness, the pilot did not execute an engine runup or a pre-takeoff checklist before departure. During the takeoff roll, the airplane began to oscillate to the right and left of the runway centerline. These oscillations increased in amplitude and continued for approximately 1,500 feet down the runway. At that point, the airplane rolled onto its right main wheel and nose wheel. It then abruptly pitched to a nose-high attitude, causing the tail to strike the runway. The airplane became airborne, reaching an altitude of about 10 feet above ground level.
Immediately after becoming airborne, the airplane banked to the right, and the right wingtip struck the runway. The airplane subsequently cartwheeled off the runway, struck a drainage ditch, and a fire erupted in the engine compartment.
Post-Accident Examination
Post-accident examination revealed that the weight and balance of the airplane were within limits at the time of the accident. However, the elevator trim control was found in the full nose-up position.
