What was found
DURING VISUAL INSPECTION, FOUND FUEL TANK BAFFLE SPOT WELDS BROKEN LOOSE, ALLOWING BAFFLE TO MOVE AROUND FREELY INSIDE FUEL TANK. COULD CAUSE FUEL STARVATION DURING DECENT WITH A LOW FUEL QUANTITY AND COULD CAUSE ERRONEOUS FUEL QUANTITY INDICATIONS DUE TO INTERFERENCE WITH TRANSMITTER FLOAT. PROBABLE CAUSE: THE FRONT FACE OF THE BAFFLE IS APPROXIMATELY 1 INCH BEHIND FUEL TANK FILLER PORT. DURING REFUELING PROCESS, IF FUEL NOZZLE IS RELAXED, NOZZLE CONTACTS BAFFLE AND APPLIES EXCESSIVE PRESSURE TO BAFFLE EVENTUALLY BREAKING SPOT WELDS LOOSE. PREVENTATIVE MEASURES: DURING THE REFUEL PROCESS, DO NOT INSERT FUEL NOZZLE MORE THAN 3 INCHES INTO THE FUEL TANK. THIS DEFECT WAS FOUND IN 4 OUT OF 8 A/C.
