The flight instructor reported that about 4 miles from the airport they attempted to contact the airstrip on the Common Traffic Advisory Frequency to obtain wind and airport advisories, but were unsuccessful in raising anyone. They then overflew the airport and looked for wind indicators, but did not find any. The instructor then used a nearby lake to judge the winds and decided to land on runway 36. Applying wind correction on final approach, the instructor landed on the center of the runway. A sudden and very strong wind gust turned the airplane to the right. The instructor said she attempted to correct with left rudder but was unable to maintain control and both wing tips contacted the ground, structurally damaging both wings. The instructor stated that there were no pre accident mechanical malfunctions or failures with the airplane. An aviation weather reporting station, located 9 nautical miles west, listed the winds as from the west at 15 knots with gusts to 25 knots. ## Factual narrative On February 14, 2007, at 1430 eastern standard time, a Cessna 172S, N289SP, drug both wing tips while landing at the Chalet Suzanne Airstrip, Lake Wells, Florida.

Applying wind correction on final approach, the instructor landed on the center of the runway. A sudden and very strong wind gust turned the airplane to the right. The instructor said she attempted to correct with left rudder but was unable to maintain control and both wing tips contacted the ground, structurally damaging both wings.
