Preflight and Run-Up
During the engine run-up, a right magneto check revealed an excessive RPM drop. In an attempt to clear the condition, the pilot leaned the mixture to burn off any deposits. This action inadvertently resulted in an engine shutdown. After restarting the engine, the pilot continued to operate with a lean mixture. A subsequent magneto check then showed readings within acceptable limits.
Loss of Power and Forced Landing
After departure, during the initial climb at approximately 300 feet above ground level, the engine began to lose power. The pilot assessed that safe flight could not be maintained and shut down the engine. A forced landing was executed to a nearby area. Upon touchdown on rough terrain, the landing gear collapsed.
Post-Accident Investigation
Investigators examined the aircraft and engine but were unable to determine the reason for the power loss during the climb. The cause of the excessive RPM drop during the initial run-up and the subsequent shutdown and restart operations were noted, but no definitive link to the in-flight power loss could be established.
