What happened
The airplane departed the paved surface approximately 300 feet from the landing threshold of Runway 25 shortly after touchdown. Environmental conditions at the airport indicated winds from 180 degrees at 7 knots. However, the pilot reported receiving wind information indicating a direction of 250 degrees with speeds between 10 and 15 knots, gusting up to 15-20 knots.
The pilot noted that the runway was narrow, which likely contributed to the difficulty in maintaining alignment. Upon initial contact with the ground, an apparent wind gust pushed the aircraft to the left of the centerline. In an effort to correct the drift and steer back toward the right, the pilot lost control of the lateral direction. Consequently, the left wingtip struck adjacent shrubbery located just off the runway edge.
The investigation
No mechanical failure or pre-impact anomaly was identified that would have prevented controlled flight. The primary factor was the loss of directional control during the landing roll on a narrow surface under crosswind conditions.
Findings
The deviation from the runway centerline was caused by a combination of wind shear and the limited width of the landing area. The pilot's attempt to correct for the leftward drift resulted in the wingtip impacting ground vegetation.
