## Discrepancy

LEFT SIDE INBOARD FLAP FAIRING WAS DANGLING AFTER FLAP RETRACTION.  *S/D*  THE NUT AND BOLT COMBINATION THAT SECURES THE CANOE FAIRING DRIVE ROD TO THE INBOARD MIDFLAP DISLODGED.  ONCE THE BOLT AND NUT DISLODGED, THE FAIRING WAS ABLE TO DROP DOWN.  THE CORRECTIVE ACTION WAS TO REPLACE THE BOLT, NUT AND COTTER PIN COMBINATION THAT ATTACHES THE FAIRING CONTROL DRIVE TO THE MIDFLAP.
