NTSB narrative
The student pilot stated that he applied takeoff power, and the airplane accelerated along the centerline of the runway. As the airplane accelerated through about 50 to 55 knots, it suddenly yawed to the left. Despite the student pilot's control inputs, the airplane continued to the left and exited the runway. Examination of the airplane's flight control system and nose wheel steering system revealed no mechanical failures or malfunctions that would have precluded normal operation.
Probable cause
The student pilot's failure to maintain directional control during takeoff.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
