At about 1430 eastern time, a Cessna 172RG, N9673B, was substantially damaged while landing at Floyd Bennett Memorial Airport. The pilot and two passengers were not injured. The pilot said he was on approach to runway 19, when he encountered a thunderstorm cell and was advised by another pilot to use runway 30. The pilot said he made the approach at about 75 to 80 knots in anticipation of crosswinds or wind shear. He said that he was touching down when he encountered a wind gust that picked up the left wing, causing the airplane to land hard. The airplane sustained damage to the propeller, firewall, nose gear and lower portions of the fuselage.
