NTSB narrative

The pilot reported that he intended to takeoff in the tai wheel-equipped airplane from runway 12 and remain in the traffic pattern. During the takeoff roll, the pilot put in full right aileron and held the elevator at a neutral position. He reported that he positioned the rudder "to maintain course on the longitudinal axis of the runway." He reported that during takeoff rotation, the airplane encountered a 5 - 7 knot right crosswind gust of wind which lifted the right wing up about 45 - 60 degrees in less than 1 second. The airplane veered to the left 45 degrees. The pilot reported that he attempted to use elevator and rudder inputs, but they "produced little or no response." The airplane veered further left, lost altitude, and impacted terrain. The right main landing gear collapsed and the tailwheel tail spring was bent left, which resulted in substantial damage. The pilot indicated that he had a total of 190 flight hours with 1 hour in make and model. The pilot reported there was no mechanical malfunction or failure.

Probable cause

The pilot's failure to maintain directional control and his inadequate compensation for the crosswind conditions. Factors included the pilot's lack of experience in the make and model of the airplane and the crosswind gust.

  • 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.
