NTSB narrative

The pilot reported that he was returning from a local area flight and made a normal approach with a 3 point touchdown. After touchdown, the left wing lifted and the airplane veered to the left. He was unable to maintain directional control so he initiated a go-around. The airplane briefly became airborne before the right wing dropped and struck the ground and the airplane came to rest facing towards the east. According to the weather station located on the airport, the wind was reported as calm at the approximate time of the accident. However, during the time period from an hour before the accident to an hour after the accident wind conditions were reported as varying from 254 to 294 degrees with speeds of 7 to 9 knots.

Probable cause

The pilot's failure to maintain directional control during a go-around.

  • 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.
