## Discrepancy

(CAN) SHORTLY AFTER REFUELING THE AIRCRAFT, A MAJOR FUEL LEAK OCCURRED. INVESTIGATION REVEALED THAT THE INCORRECT SIZE OF CLAMPS WERE INSTALLED ON AN INTERCONNECT FUEL TANK HOSE. THE CLAMP FOUND IN USE WAS AN AN737TW-74. THE PARTS MANUAL SHOWS AN AN737TW-56 CLAMP. THIS PROBLEM IS RELATIVE TO BELLANCA SCOUTS WITH THE 70 GAL LONG RANGE FUEL TANK.
