(Pilot) Switched To The Left Reserve Fuel Tank, When The Engine Began To Sputter
Analysis: The pilot reported that during the flight to his return airport, his cruise altitudes had varied from 4,000 ft to 8,000 ft mean sea level (msl) due to mountainous terrain. About an hour into the flight, he switched to the left reserve fuel tank, when the engine began to sputter. Despite switching back to the right fuel tank, the engine lost all power. The pilot initiated a forced landing to an open field and during the landing, the airplane impacted a covered dirt berm, substantially damaging the forward fuselage and left wing.
