## Discrepancy

ON DEPARTURE OUT OF SAN, AFTER GEAR RETRACTION, THE NOSE GEAR DID NOT COME UP. WE RECEIVED MULTIPLE EICAS MESSAGES  AS WELL AS AN AMBER GEAR CONTROL FAULT. WE RAN THE GEAR CONTROL FAULT CHECKLIST AND LOWERED THE GEAR AS PER THE CHECKLIST. THE GEAR THEN SHOWED DOWN AND LOCKED.  WE SPOKE WITH MX AND FODM AND CONTINUED TO VNY WITH THE GEAR IN THE DOWN POSITION.  REPEAT WRITE UP - EXCEPT THE GEAR DID NOT COME UP AFTER A MINUTE AND A HALF.  INSPECTED RT PROX SWITCH & FOUND PROX SENSOR WAS AT .026, RIGGED RT PROX SWITCH TO .015. REF AMM 32-60-06, ACCOMPLISHED RT PROX SWITCH RIGGING CHECK THROUGH MAINTENANCE DATA SCREEN ON MFD AND CONFIRMED CORRECT PROX SENSOR SIGNAL AT 4973. REF AMM 32-60-00.
