## Discrepancy

ON APPROACH PILOT SELECTED FULL FLAPS, HEARD LOUD POP AIRCRAFT WANTED TO ROLL RIGHT.  CORRECTED WITH AILERON, DECLARED EMERGENCY AND LANDED WITHOUT INCIDENCE.  INSPECTED AIRCRAFT FOUND THAT A FLOOR PANEL CLIP NUT HAD BECOME CAUGHT IN FLAP DRIVE GEAR/CHAIN CAUSING INCREASED TENSION ON CABLE CAUSING IT TO SNAP.  REPLACED CABLE WITH NEW AND RIGGED FLAPS.
