## Discrepancy

LANDING GEAR WOULD NOT EXTEND.  RECYCLED,  THEN USED THE MANUAL EXTENSION.   DURING GEAR SWING, ON RETRACTION,  THE NOSE GEAR DOORS STAYED AMBER.  FOUND THE RELAY 62GA TO BE DEAD.  R & R THE RELAY 62GA IAW ESPM 20-46-50. OP CHECKED GOOD.  FOUND THE NLG DOOR SENSOR 31GA HITTING CFDS.  R & R THE SENSOR 31GA IAW AMM 32-31-13.  OPS CHECKED GOOD.  PERFORMED A FUNCTIONAL CHECK OF NORMAL EXTENSION AND RETRACTION OF THE LANDING GEAR IAW AMM 32-31-00-720-002-A,  OPS CHECKED GOOD. ACFT OKAY FOR CONTINUED SERVICE.
