Probable cause

A loss of engine power for reasons that could not be determined based on the available evidence.

NTSB analysis

The pilot stated that he conducted a preflight inspection, during which he sampled the fuel and recovered about 4 ounces of water. He then performed an engine run-up and taxied to the runway for departure. During the climbout, when the airplane was about 100 ft above ground level, the engine lost total power. The pilot performed a forced landing, and the airplane collided with trees. The fuselage, wings, and empennage were substantially damaged during the impact. Postaccident examination of the engine revealed a large bird nest in the engine cowling and cabin air intakes. The condition of the engine air intake could not be determined due to impact damage. The propeller was able to rotate and valvetrain continuity and the operation of the magnetos was confirmed. Given the available evidence, the reason for the loss of engine power could not be determined.
