Aircraft Accident/Incident Report

Wellsville, Kansas 66092
Sunday, November 5, 2006 11:00 CST

NTSB Narrative Summary Released at Completion of Accident

The pilot said the engine made a loud "bang" approximately 10 minutes into the flight and lost power. The airplane was vibrating, so the pilot secured the engine and shut off the fuel supply. The pilot declared an emergency, then attempted to land in a bean field. The airplane had "insufficient speed and altitude" to clear a tree line and struck the trees. Engine disassembly revealed the number 2 intake valve had been completely "swallowed" into the cylinder. The engine had accrued 1,700.49 hours since overhaul. The rated time-between-overhaul for the Continental C-90-12F engine is 1,800 hours.

NTSB Probable Cause Narrative

A loss of engine power due to the ingestion of the number 2 intake valve into its cylinder. Contributing factors included the pilot allowing the airspeed and altitude to drop, making a safe landing not possible.
