NTSB narrative
The pilot reported that during the takeoff roll, he attempted to close a window vent and the airplane veered off the left side of the runway. He aborted the takeoff and taxied back for takeoff; he examined the airplane before takeoff and did not see any damage. After landing, he secured the airplane in the club hangar. During a flying club meeting 4 days later, the pilot observed damage to the right wing; subsequent examination revealed substantial damage to the wing spar. The pilot reported that there were no mechanical malfunctions or anomalies with the airplane before the runway excursion.
Probable cause
The pilot’s loss of directional control during the takeoff roll, which resulted in a runway excursion.

- 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.
