Probable cause

The pilot’s inadequate compensation for crosswind conditions during initial climb, which resulted in an impact with trees and terrain.

Findings · 3

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

According to the pilot’s statement, just before takeoff, he noted that the windsock was “still” and initiated his takeoff roll. About 15 to 20 feet above ground level (agl), the flight encountered a left crosswind causing the airplane to go to the right. The pilot corrected by immediately applying left aileron and left rudder control inputs, then removed the aileron and rudder control inputs. The flight continued and about 30 feet agl, the flight encountered another wind gust that pushed the airplane to the right “faster” than the pilot could apply corrections. The right wingtip impacted a treetop causing the airplane to reverse its direction, descend rapidly, and impact the ground. The airplane sustained substantial damage to the wings and fuselage. The pilot reported no preimpact mechanical failures or malfunctions that would have precluded normal operation. Weather data recorded around the time of the accident at the nearest observation facility indicated wind from 30 degrees at 9 knots. A representative of the airplane designer reported that a 5- to 10-knot crosswind is well within the airplane’s maximum demonstrated crosswind limitation.

Factual narrative

The pilot was attempting to depart the airport to return home in the experimental light sport aircraft. According to the pilot’s statement, just before takeoff, he noted that the windsock was “still” and initiated his takeoff roll. About 20 feet above ground level (agl), the flight encountered a left crosswind causing the airplane to go to the right. He corrected by immediately applying left aileron and left rudder control inputs, then removed the aileron and rudder control inputs. The flight continued and about 30 feet agl, the flight encountered another wind gust that pushed the airplane to the right “faster” than he could apply corrections. The right wingtip impacted a treetop causing the airplane to reverse its direction, descend rapidly, and impact the ground causing structural damage to the wings and fuselage. The pilot reported no preimpact mechanical failures or malfunctions. A representative of the airplane designer reported to NTSB that a 10 knot crosswind is well within the airplane’s maximum demonstrated crosswind limitation.
