NTSB narrative
The pilot reported that she made a normal landing on the runway and that the winds were calm. She said that during the landing the airplane swerved to the right. She attempted to correct the swerve, but with no success. The airplane exited the runway and struck a drainage ditch on the side of the runway. Rudder control continuity was established at the accident site. Detailed examination of the aircraft disclosed no preimpact damage or malfunctions on the landing gear, brakes, or nose gear. The student pilot had logged over 49 hours of dual instruction with 6 hours of flight time with the instructor who had approved her solo flights.
Probable cause
Failure of the student pilot to maintain directional control.

- 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.
