Aircraft Accident/Incident Report
Washougal, Washington 98671
Thursday, July 23, 2009 19:15 PDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that the airplane’s engine lost power immediately after takeoff from a private airfield. The left wing then struck a large tree and the airplane subsequently crashed into wooded terrain, which resulted in structural damage to both wings and fuselage. Post accident examination of the engine disclosed that the (top) electrode areas of the spark plugs were oil soaked, and severe wear was noted to the ground and center electrodes. Further examination revealed that the number 4 cylinder exhaust valve was stuck in the open position. The valve remained stuck during a functional check and was later removed utilizing a punch and heavy hammer. A dark brown material and smearing was noted along the exhaust valve neck. Comparable material and smearing was observed along the interior surface of the exhaust valve guide. No additional mechanical anomalies were noted with the engine.
NTSB Probable Cause Narrative
A loss of engine power during initial climb due to a stuck exhaust valve.
