## Discrepancy

DURING FLIGHT, THE RIGHT MAIN LANDING GEAR 'A' GREEN LIGHT ILLUMINATED.  LIGHT REMAINED ON FOR THE REMAINDER OF THE FLIGHT.  LANDING GEAR COULD ONLY BE EXTENDED USING THE EMERGENCY EXTENSION SWITCH.  REPLACED RIGHT MAIN 'A' SYSTEM DOWNLOCK PROXIMITY SENSOR.  CYCLED GEAR.  OPS CHECKS GOOD AT THIS TIME.
