Analysis

After touchdown, the airplane departed the runway about 300 feet from the landing end of runway 25. Winds were 180 degrees at 7 knots. The pilot reported the winds as being 250 degrees at 10-15 knots, gusting to 15-20 knots. The pilot stated that she was landing on a narrow runway. She stated that when the wheels touched down, she realized an apparent wind gust had forced the aircraft to the left of the centerline. As she attempted to steer back to the right, the left wing tip struck adjacent shrubbery.
