The pilot stated that he had decided to return to his originating airport after having been advised by air traffic control of an inbound thunderstorm during a local flight. The pilot obtained an instrument flight rules clearance and headed towards the airport, which was in the direction of the storm. During the first landing attempt on runway 30, the pilot noted strong wind gusts and "extreme precipitation," but elected to continue the landing. About 30 feet above the runway, a "strong windshear" forced the airplane onto the runway, which resulted in substantial damage to the left wing. The airplane subsequently lifted off the ground again and the pilot initiated a go-around. The pilot circled the runway and aborted three more attempts before he successfully landed the airplane. He reported that there were no preimpact mechanical malfunctions or anomalies that could have precluded normal operation. The pilot stated that he had obtained some weather information prior to his departure, but was not aware of the thunderstorm. A review of weather radar revealed the presence of strong winds and heavy precipitation over the pilot's originating airport at the time of the accident. Winds reported at the accident site about 10 minutes after the accident were from 320 degrees at 16 knots, gusting to 27 knots. There were also area forecasts for convective activity and Convective Sigmets that had been issued for the pilot's route of flight about one hour and thirty minutes prior to his departure.
