THE AIRPLANE WAS IN CRUISE FLIGHT WHEN THE PILOT NOTED A RIGHT WING HEAVY CONDITION. HE ATTEMPTED TO CORRECT THE CONDITION BY TURNING THE AIR PRESSURE VALVE FROM BOTH TIP TANKS TO THE RIGHT TIP TANK. AFTER 10 TO 15 MINUTES, THE PROBLEM WAS NOT RESOLVED AND A PRECAUTIONARY LANDING WAS MADE. DURING THE LANDING ROLL, THE LATERAL BALANCE LIMITS COULD NOT BE MAINTAINED BY THE PILOT AND THE RIGHT WING TANK STRUCK THE GROUND. THE WIND WAS GUSTING BETWEEN 20 TO 35 KNOTS AT THE TIME, ACCORDING TO THE PILOT. THE AIRPLANE VEERED TO THE RIGHT AS CONTROL WAS LOST. THE LANDING GEAR COLLAPSED BEFORE THE AIRPLANE CAME TO REST. A SMALL FIRE STARTED AFTER THE PILOT AND HIS PASSENGER EXITED THE AIRPLANE. TESTING WAS ACCOMPLISHED ON THE COMPONENTS FOR THE FUEL SYSTEM UNDER THE DIRECTION OF THE FAA. THE RESULTS OF THE TESTS REVEALED AN INOPERATIVE RIGHT WING BLEED AIR CHECK VALVE. IT WAS FOUND CORRODED WITH THE PLUNGER AND SPRING STUCK
Probable Cause: A CORRODED BLEED AIR CHECK VALVE AND SUBSEQUENT FAILURE OT THE RIGHT WING'S FUEL TRANSFER SYSTEM. A FACTOR WAS THE UNFAVORABLE WIND
