## Discrepancy

(CAN) AFTER SELECTING THE LANDING GEAR UP ON DEPARTURE, THE RIGHT GEAR DOOR ANNUNCIATOR REMAINED ILLUMINATED. VISUALLY VERIFIED THAT THE RIGHT GEAR DOORS WERE OPEN. MAINTENANCE DETERMINED THE SOLENOID SEQUENCE VALVE WAS AT FAULT AND REPLACED THE PART (WHICH HAD BEEN INSTALLED SINCE NEW AIRCRAFT DELIVERY). THE LANDING GEAR WAS FUNCTION TESTED SERVICEABLE AND THE AIRCRAFT WAS SUBSEQUENTLY RETURNED FOR SERVICE.
