## Discrepancy

DURING APPROACH, NOSE GEAR RED LIGHT WOULD NOT EXTINGUISH.  AFTER COMPLETEING ALTERNATE GEAR EXTENSION RED NLG LIGHT STAYED ILLUMINATED AND FINALLY EXTINGUISHED AFTER A FEW MINUTES.  REMOVED AND REPLACED PSEU AND NOSE GEAR DOWNLOCK PROX SENSOR.  PERFORMED EXTENSION AND RETRACTION CHECKS.  OPS CHECK GOOD.
