## Discrepancy

THE LANDING GEAR WOULD NOT RAISE AFTER TAKEOFF FROM RDU. THE GEAR HANDLE WOULD NOT MOVE PAST THE OFF POSITION. THE AIRCRAFT WAS RETURNED TO RDU WHERE IT LANDED WITHOUT INCIDENT. MAINTENANCE FOUND THAT JUMPER, DIODE M416, ON BACK OF THE GEAR LEVER ASSEMBLY WAS POPPING LEVER LATCH CIRCUIT BREAKER WHEN HOOKED INTO SYSTEM. THE DIODE WAS FOUND MIS-CONNECTED. THERE WAS NO HISTORY OF WORK IN THIS AREA AND NO PREVIOUS WRITEUPS FOR THIS PROBLEM. THE DIODE WAS RECONNECTED IAW WIRING DIAGRAM 31-31-01 AND ALL GROUND OPERATION WAS NORMAL.
