Read the full NTSB narrative

ON DOWNWIND TO LAND, BOTH ENGINES LOST POWER DUE TO FUEL STARVATION. CONTROL OF THE AIRPLANE WAS NOT MAINTAINED AND THE AIRPLANE IMPACTED IN AN OPEN CLEARING AT A STEEP ANGLE. THE FUEL SELECTOR VALVE HANDLES INDICATED OPPOSITE (180 DEGREES OUT) OF THE ACTUAL FUEL VALVE POSITION SELECTED. NO FUEL WAS EVIDENT IN THE LEFT AUXILIARY TANK AND THERE WAS EVIDENCE OF FUEL IN THE OTHER 3 TANKS. NO INDICATION OF FUEL OR PROPELLER ROTATION WAS FOUND AT THE LEFT ENGINE. FUEL AND SOME ROTATION WAS EVIDENT AT THE RIGHT ENGINE. NEITHER PROP WAS FEATHERED, FLAPS WERE UP AND LANDING GEAR WAS DOWN. THE MANDATORY SERVICE BULLETIN (MSB) RECENTLY INSTALLED INVOLVING THE FUEL SELECTOR VALVE HANDLES COULD NOT BE PERFORMED AS PER THE INSTRUCTIONS. THE MECHANIC MODIFIED THE KIT PROCEDURES, RESULTING IN THE SELECTOR HANDLES BEING INSTALLED OPPOSITE OF THE FUEL PORT POSITION.
