Summary
A pilot reported mechanical issues with the aircraft prior to departure but decided to fly to another airport for repairs. During the flight, the right engine was shut down due to an oil leak. While attempting to crossfeed fuel, the pilot inadvertently activated the left engine firewall fuel shutoff valve, causing a loss of power in the left engine. The aircraft subsequently performed a forced landing on rough tundra, resulting in substantial damage.
Details
According to the pilot, the aircraft had preexisting mechanical problems, yet the decision was made to return it to a different airport where repairs could be performed. En route, the pilot observed an oil leak from the right engine and decided to shut it down. Later, while trying to crossfeed fuel between the engines, the pilot accidentally moved the left engine firewall fuel shutoff valve. This action cut off fuel supply to the left engine, leading to a complete loss of power. With both engines inoperative, the pilot was forced to land on uneven tundra terrain. The aircraft sustained substantial damage during the landing. No other information about the aircraft, location, or occupants was provided in the source.
