## Discrepancy

(CAN) DURING TROUBLESHOOTING OF A LANDING GEAR PROBLEM WE NOTICED THAT THE NUT ASSEMBLY IN THE NOSE GEAR ACTUATOR COULD MOVE A SMALL AMOUNT FROM SIDE TO SIDE PLAY IN THE HOUSING. THE ACTUATOR WAS REMOVED AND WE NOTICED THAT THE MECHANISM WAS A LITTLE ROUGH WHEN TURNED BY HAND. THE ACTUATOR WAS RETURNED TO THE OVERHAUL SHOP FOR FURTHER INVESTIGATION. THE OVERHAUL SHOP HAS RESPONDED: UNIT FAILED THE END PLAY TEST AND SCREW/NUT ASSEMBLY SEEMED TO HAVE SOME SIDE TO SIDE PLAY. DISASSEMBLED, INSPECTED, NDT, ECT FOUND: SCREW ASSEMBLY / NUT ASSEMBLY OUT-OF-LIMITS. HOUSING HAS DEEP CORROSION PITTING IN BOLT HOLE BOSS .THIS ACTUATOR WAS OVERHAULED IN APRIL 2003 AND ONLY HAD 819 CYCLES SINCE THEN.
