What was found
RETURN TO FIELD DUE TO A FUEL QUANTITY ISSUE. OPERATED BOTH ENGINES TO OBSERVE ENGINE FUEL BURN AND THE POSSIBILITY OF FUEL LEAKS. VISUALLY CHECKED MFLI (MAGNETIC FUEL LEVEL INDICATORS) FOR VERIFICATION OF FUEL QUANTITY INDICATIONS. ALSO, FQIC (FUEL QUANTITY INDICATING COMPUTER) WAS REPLACED AND OPERATIONAL TEST OF FUEL TRANSFER SYSTEM WAS PERFORMED. NO SIGNS OF EXTERNAL LEAKS AND MFLI'S MATCHED FUEL QUANTITY INDICATIONS. FUEL TRANSFER SYSTEM OPERATIONAL CHECK WAS NORMAL. ENGINEERING WILL CONTINUE TO MONITOR BUT NO ISSUES NOTED SINCE INCIDENT.
