## Analysis

THE ACFT LOST POWER AT ABOUT 200 FT AGL DURING TAKEOFF. THE PLT FEATHERED THE RIGHT ENGINE AND THEN ELECTED TO LAND ON THE REMAINING RWY WHEN THE LEFT ENGINE LOST POWER. THE ACFT WENT OFF THE RWYS END WITH BRAKES LOCKED. WHEN THE ACFT WAS EXAMINED BY FAA ABOUT 2 OUNCES OF WATER WERE FOUND IN THE FUEL FILTER BOWL OF THE RIGHT ENGINE. EACH CARB CONTAINED ABOUT 2 TABLESPOONS OF WATER. THE SPARKPLUGS HAD ACCUMULATED A LARGE AMOUNT OF CARBON. ALL ELSE APPEARED NORMAL.
