NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot reported that shortly after takeoff, about 400 feet above the ground, he sensed that the airplane was not climbing normally and that the engine was not producing takeoff power. The pilot stated that he made a forced landing after he was unable to restore takeoff power or maintain altitude. The airplane impacted a tree and descended a hill before coming to a stop. A postaccident engine examination revealed that the No. 3 cylinder exhaust valve was stuck in the full open position. No visible debris was noted under the valve seat that would have prevented the valve from closing. A stuck exhaust valve would have resulted in a loss of engine power. No additional malfunctions or failures were revealed during the engine examination that would have prevented normal operation. The engine had accumulated about 698 hours since its last major overhaul.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The partial loss of engine power due to an exhaust valve that was stuck in the open position. Full narrative available
