## Discrepancy

(CAN) AC HAD THE FLAP STUCK FULL DOWN. INSP REVEALED THAT FLAP ACTUATOR SEAL HAD COME LOOSE AND INTERFERED WITH THE NR5 FLAP SWITCH. A/C WAS IN MAINT FOR A TOTALLY UNRELATED DEFECT, TROUBLESHOOTING DECIDED, THAT WE TAKE THE ACTUATOR FROM IT TO USE ON A/C. INSP REVEALED THAT THE SEAL ON A/C HAD COME LOOSE TOO, BUT HAD NOT YET CONTACTED THE SWITCHES AND THEREFORE WE RE-GLUED SEAL IAW MFG INSTRUCTIONS AND INSTALLED THIS UNIT ON MFB. THEREAFTER UNIT WHICH WAS REMOVED FROM MFB WAS FURTHER INSPECTED, SEAL RE-GLUED AND TAB OF NR5 SWITCH WAS STRAIGHTENED.  UNIT INSTALLED IN OTHER A/C AND GROUND TESTED SERVICEABLE.
