Probable cause

The loss of engine power due to debris in the engine air intake system.

NTSB narrative

The engine gradually lost power after takeoff, and the pilot executed a forced landing to a field. The airplane sustained substantial damage to the wings and fuselage. A postaccident examination of the airframe and engine revealed debris in the engine air intake system, which significantly reduced the air available for combustion. The engine was subsequently removed from the airframe and run in a test cell. The test run revealed no anomalies with respect to engine operation.

Analysis
