## Discrepancy

PILOT REPORTED THAT THE FLAPS WOULD NOT GO DOWN.  INSPECTION REVEALED THAT THE ROLL PIN WHICH IS USED TO LOCK THE ROD END BEARING AT THE END OF THE FLAP ACTUATOR WAS MISSING ALLOWING THE FLAP ACTUATOR ROD TO ROTATE AND ALLOW FOR MIS-ALIGNMENT OF ALL FLAP CONTROL SWITCHES.  REPAIRED FLAP ACTUATOR INSTALLED.
