Analysis

The pilot stated that he was flying a search and rescue mission for a missing aircraft when he noticed that his airspeed indicator was not working. He landed on a lake in gusty wind conditions to correct the problem. During the ensuing takeoff attempt, a gust of wind lifted the left wing and the right wing contacted the water, causing the airplane to nose over. Pilot stated he would not have flown in wind conditions except that the mission was to help search for fellow pilot.
