## Discrepancy

(CAN) WHILE CONDUCTING DISASSEMBLY OF NOSE GEAR FOR OVERHAUL, THE PISTON TUBE WAS FOUND TO HAVE SUBSTANTIAL DAMAGE TO THE UPPER THREADED END BY WHAT APPEARS TO BE ELECTRICAL ARCING. THIS HAS RESULTED IN MATERIAL LOSS AND PISTON TUBE DEEMED UNSERVICEABLE. OTHER AREAS OF NOSE GEAR WERE INSPECTED, BUT FURTHER DAMAGE WAS NOT FOUND.
