NTSB narrative

The commercial certificated pilot/hunting guide was landing at a remote airstrip located on a mountain ridge with an assistant guide. The purpose of the flight was to establish a camp for his hunting clients. The landing strip is oriented north/south at 3,500 feet msl, and is 850 feet long, and 30 feet wide. The pilot had landed on the ridge numerous times in the past. The pilot said he made several low passes over the area to assess the landing area and wind conditions. During the low passes over the ridge, he noted a quartering head wind from the right, of 10 miles per hour. He said he landed on the ridge, but just after touchdown, encountered a wind gust that pushed the airplane to the left. He added engine power to abort the landing. The tailwheel came off the ground, and he turned the airplane downhill to the left to gain airspeed. The right wing, and the main tires struck the ground on the downhill side of the ridge. The airplane received damage to the landing gear, and the right wing spar.

Probable cause

The pilot's inadequate compensation for wind conditions. Factors in the accident were a crosswind, and wind gusts.

  • 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.
