NTSB Narrative Summary Released at Completion of Accident

While descending through 2,000 feet, the Mooney M20E's Lycoming IO-360-A1A engine stopped operating. The pilot switched fuel tanks and activated the fuel boost pump without success, and then executed a forced landing to rough/uneven terrain in an agricultural field. On site examination revealed fuel in both fuel tanks. The FAA inspector assigned to the accident reported that in a post-crash examination and test run of the engine the 'fuel control servo appeared to be blocked for unknown reason' and that 'fuel pressure going in the fuel servo was considerably/extremely low at [the] outlet and would not sustain engine operation.' The fuel servo was removed and flow checked with no discrepancies noted. The servo was then re-installed in the aircraft and the FAA inspector observed a second test run during which the engine successfully operated with no discrepancies noted.

NTSB Probable Cause Narrative

A loss of engine power for undetermined reason(s). A factor was the rough/uneven terrain.
