MAULE M-4-220C
A MAULE M-4-220C COLLIDED WITH A FOUR FOOT HIGH DIRT BANK AFTER A LOSS OF ENGINE POWER DURING TAKEOFF. THE PILOT REPORTED THE ENGINE POWER WAS SURGING DURING THE INITIAL TAKEOFF CLIMB. AT 75 FT AGL THE ENGINE STOPPED. THE ENGINE STARTED AND RAN WITHOUT ANY MALFUNCTIONS DURING A POST ACCIDENT EXAM. THE PILOT SUSPECTED POSSIBLE WATER IN THE FUEL OR SEDIMENTS TEMPORARILY BLOCKING A FUEL LINE. THE AIRPLANE WAS LAST FLOWN 1 WEEK EARLIER FOR 1 HR AND 15 MIN. FUELING RECORDS ESTABLISHED THAT THE AIRPLANE WAS FUELED WITH 8.9 GALLONS OF AVIATION FUEL AFTER THE FLIGHT. THE FUEL CONSUMPTION FOR THE ENGINE AVERAGES IN EXCESS OF 12 GAL/HR. THE FAA RECOMMENDS THAT THE FUEL TANKS BE COMPLETELY FILLED AFTER EACH FLIGHT, OR AT LEAST AFTER THE LAST FLIGHT OF THE DAY. THE REASON IS THAT WHEN AIR IN THE FUEL TANK COOLS, THE MOISTURE IT CONTAINS CONDENSES INTO WATER, AND CONTAMINATES THE FUEL. PILOTS SHOULD TAKE THE NECESSARY STEPS TO ELIMINATE IT DURING PREFLIGHT INSPECTION.
THE FAILURE OF THE PILOT-IN-COMMAND TO PERFORM AN ADEQUATE PREFLIGHT INSPECTION BY TAKING THE NECESSARY STEPS TO ELIMINATE WATER CONTAMINATION OF THE AIRPLANE'S FUEL SYSTEM.
