The pilot landed short and nosed over in shallow water during an attempt to land on a sandbar. The inspector reported that the tubular wing support structure and left wing sustained substantial damage. When asked by the inspector what might have caused the engine to fail, the pilot responded, "I think I loaded it up when I added power and the engine quit." The inspector stated that attempts to meet with the pilot to discuss the accident further were unsuccessful. The pilot failed to submit a NTSB Form 6120.1, Pilot/Operator Aircraft Accident/Incident Report as requested. ## Factual narrative In a telephone interview with a Federal Aviation Administration inspector, the non-certificated pilot reported that while descending to land the engine failed to respond to throttle input and lost power.
