Probable cause

The pilot's failure to maintain bank control during takeoff in gusting crosswind conditions, resulting in a loss of control in flight and subsequent impact with terrain.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel equipped airplane reported that prior to departure, while he refueled the airplane and taxied to the runway, the wind was "picking up and gusting" but "were comfortably within [his] personal and aircraft limits." During takeoff, as he "rolled on the power," the right wing started to lift so he corrected with full control input left but the airplane rolled to the right and impacted terrain. The pilot added that he did not get a wind check The airplane sustained substantial damage to both wings and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The airport's automated weather observation station reported that, about the time of the accident, the wind was 220° at 24 knots, gusting to 38 knots. The airplane was departing from runway 26. According to the manufacturer's Pilot's Operating Handbook for an unmodified airplane, the maximum demonstrated crosswind is 11.7 knots. The steady state crosswind component for the accident flight was 15 knots, with gusting winds, the crosswind component for the accident flight was 24 knots.
