NTSB narrative
The student pilot reported that the purpose of the solo flight was for him to practice soft-field takeoffs from a hard surface runway. During the takeoff roll, the airplane encountered a sudden gust of wind and the student pilot was unable to maintain directional control. The airplane veered to the left of the runway centerline and continued off the surface, colliding with several signs before coming to rest in a grassy area. The airplane sustained substantial damage to the left wing. The student pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. The student pilot further reported that the accident could have been prevented if he was more vigilant of sudden gusts of wind even in reported calm wind conditions.
Probable cause
The student pilot's loss of directional control during takeoff from a runway, which resulted in a collision with a sign.

- 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, coordinates. 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.
