## Discrepancy

LEFT FLAP OUTBOARD LOWER ACTUATOR COVER PLATE FOUND DISTORTED AND BENT. UPON INVESTIGATION FOUND CIR-CLIP FOR LOWER GIMBLE PIN MISSING. THIS MISSING CLIP ALLOWED GIMBLE PIN TO DROP DOWN. WHILE PIN WAS BACKING OUT AND DURING FLAP OPERATION DAMAGED OCCURRED TO THE FLAP ACTUATOR COVER PLATE AND FLAP STRUCTURE.  REPLACED POWER UNIT-FLAP DRIVE. COMPLETED REPAIRS TO COVER PLATE AND FLAP STRUCTURE PER LEAR INSTRUCTIONS.  SUGGEST INSPECTION FOR CIR-CLIPS AT AN INCREASED INTERVAL.
