Forced Landing After Loss of Engine Power During Cruise (N313W)

Forced Landing Following Engine Power Loss

A pilot executed a forced landing after a loss of engine power during cruise flight. The airplane was part of a formation flight at the time of the initial loss of engine power.

Pilot's Account

The pilot stated that about 10 minutes after takeoff, the engine "began to hesitate during large throttle excursions and faltered upon [application of] full throttle." He left the formation with the intention of returning to the departure airport. However, "the engine began making loud noises and the RPM sagged to 2,000," with the manifold pressure approximately 10 inches. He subsequently executed a forced landing to a cornfield.

Post-Accident Engine Examination

A post accident engine examination did not reveal any anomalies associated with a pre-impact engine failure. The engine assembly was subsequently run on a test stand for approximately 30 minutes. No anomalies were detected during the engine run.
