What was found
GSO - FLT 1147 - THE LANDING GEAR WOULD NOT RETRACT AFTER TAKEOFF FROM GSO. 'ABNORMAL' PROCEDURES WERE C/W, BUT, THE GEAR HANDLE WOULD ONLY GO TO THE UPLATCH POSITION AND THE AIRCRAFT WOULD NOT PRESSURIZE. THE AIRCRAFT WAS RETURNED TO GSO WHERE IT LANDED WITHOUT INCIDENT. MAINTENANCE FOUND THE NLG STRUT ALMOST FLAT. THE NOSE STRUT WAS FULLY SERVICED PER MM 32-21-2 AND THE SCHRADER VALVE WAS REPLACED. A NOSE GEAR RETRACTION WAS PERFORMED AND OPERATION CHECKED GOOD. (X)
