Probable cause
A partial loss of engine power due to the No. 4 cylinder’s stuck exhaust valve.
NTSB analysis
The student pilot and flight instructor reported that the engine lost partial power after takeoff, when the airplane was climbing. The instructor assumed control of the airplane, attempted to restore power, and performed a forced landing. The airplane contacted trees and a powerline during the landing.
Postaccident examination of the engine revealed that the exhaust valve in the No. 4 cylinder was stuck in the open position. Based on this finding, it is likely that the partial loss of engine power was the result of the No. 4 cylinder’s stuck exhaust valve.
