| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot of the tailwheel-equipped, experimental, amateur-built airplane, who was also an airframe and powerplant mechanic, reported that, during approach to a sandbar, he side-slipped the airplane and that the engine then lost power because he was "too aggressive with the throttle and pulled it enough to bend the [carburetor] idle stop screw bracket." The engine was normally quiet, the airplane was sound proofed, and the pilot also used a noise-cancelling headset, which prevented him from being aware of the power loss until he attempted to add power to no avail. He did not have enough time to restart the engine, so the airplane settled onto the water about 15 to 20 ft short of the sandbar. Subsequently, the airplane hydroplaned and then came to rest on the sandbar inverted. The pilot reported that the reason he was aggressive with the throttle was because of a lean mixture that tended to overheat the engine during takeoff or cruise on hot days.
The airplane sustained substantial damage to the left wing lift strut, left wing, and rudder.
Probable Cause and Findings
The pilot's improper engine modification and operation, which resulted in a total loss of engine power due to fuel starvation, and the pilot's failure to maintain an adequate approach path, which resulted in the airplane landing short of the runway.
