## Discrepancy

(CAN) ANTI CHAFE RUBBER STRIPS UNBONDED FROM STRAPS LOOSENING TENSION ON TANK. TANK MOVEMENT IN WING CAVITY CAUSED A FATIGUE CRACK WHERE FILLER NECK WAS WELDED TO TANK SINCE FILLER IS SCREWED TO STRUCTURAL PANEL (UPPER WING SKIN). FUEL LEAK WHEN TANK WAS FILLED (INTERMITTENT LEAK FIRST SUSPECTED AS FUEL GAUGE TRANSMITTER)
