## Discrepancy

WHILE INSTALLING ACTUATOR IN RT FLAP OTBD POSITION, FOUND STOP ON END OF JACKSCREW LOOSE.  FURTHER INVEST REVEALED THAT PIN WHICH HOLDS EXTEND STOP ON END OF JACKSCREW WAS SHEARED OFF.  APPROX  .1875 INCH OF PIN REMAINED ON ONE SIDE OF STOP ATTACHING IT TO JACKSCREW.  EXTEND STOP MAY BE CONTACTED UPON EMERGENCY FLAP EXTENSION.  PIN APPEARED TO BE CORRODED.  ONLY VISUAL CHECK OF ACTUATOR IS REQUESTED.  ACTUATOR IS NOT FIELD REPAIRABLE PER GULFSTREAM TECH OPS.  UNIT SENT TO GULFSTREAM FOR REPAIR.
