A pilot taxied for takeoff at dusk with strong crosswinds when the left wing tip struck trees. The accident occurred during a period of restricted night flight visibility.
What happened
The pilot reported encountering strong crosswinds while taxiing the aircraft for takeoff on the airstrip. At approximately 45 miles per hour, the left wing tip struck trees. The accident occurred during dusk, with the sun's elevation at -3.5 degrees below the horizon. The pilot had a restriction on his pilot certificate prohibiting night flight.
Findings
The left wing tip struck trees during the takeoff taxi phase. The pilot was operating under a night flight restriction. The strong crosswinds may have contributed to the loss of control or situational awareness during the low-light conditions.
