First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

Several witnesses observed the airplane as it was attempting to land on a turf runway, and recalled that it was higher and faster than normal. The witnesses then observed the airplane strike a tree, and descend to the ground. Examination of the accident site revealed that the airplane struck a 50-foot high tree located about 445 feet prior to the runway threshold. According to an FAA Airport Facilities Directory, the runway was a 2,466-foot long, 50-foot wide turf runway, and had a 756 foot displaced threshold, marked with lime. The directory also mentioned trees were located at the approach end of the runway. Examination of the runway revealed large patches of brown grass and tire marks were observed about 10 feet beyond the beginning of the runway surface. No markings were observed identifying a displaced threshold. The pilot was also the owner and manager of the airport. The winds reported at an airport located about 3 miles north of the accident site, about the time of the accident, were from 200 degrees at 13 knots, gusting to 19 knots.

Probable cause

The pilot's misjudgment of altitude/distance and his failure to maintain adequate clearance from trees while landing. Factors related to the accident were the lack runway displaced threshold markings, the trees located at the end of the runway, and the gusting wind conditions.

  • 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.
