Confidence Rating: Accident investigation report completed and information captured
The student pilot reported that, during takeoff, he felt the airplane dip right. When he reduced the throttle and applied brakes, the airplane suddenly spun left and exited the runway. A witness located adjacent to the accident site reported that he observed the airplane veer left during the takeoff, that he heard the engine power reduce, and that he observed the right main landing gear begin to “flip around” as the airplane exited the left side of the runway. Subsequently, the airplane came to rest adjacent to the runway in the opposite direction of the takeoff; the right main landing gear had separated. Postaccident examination of the airplane did not reveal any preaccident mechanical anomalies that would have precluded normal operation. Skid marks observed on the runway were consistent with all three tires skidding left to the edge of the runway before the right main landing gear separated. Recorded weather information revealed that, about 5 minutes after the accident, the wind was about 10 degrees left of the runway heading at 6 knots.

Probable Cause: The student pilot’s failure to maintain directional control during takeoff.
