## Discrepancy

DURING TAKEOFF ROLL THE RIGHT GEAR RED LIGHT CAME ON AFTER GEAR RETRACTION THE RED GEAR LIGHT REMAINED ON WITH ALL OTHER GEAR LIGHTS EXTINGUISHED (GEAR WAS RE-CYCLED).  REPLACED RT MAIN GEAR UPLOCK SENSOR PER M/M 32-61-081-4.  ALSO REPLACED THE LANDING GEAR ACCESSORY UNIT PER M/M 32-09-121-4.  ALL CHECKS OK.
