THE RIGHT MAIN GEAR "IN TRANSIT" LIGHT REMAINED ON AFTER GEAR RETRACTION ON A TRAINING FLIGHT. VARIOUS METHODS OF REMEDIAL ACTION DID NOT CURE THE PROBLEM. A LANDING ON RUNWAY 21 WAS EXECUTED WITH THE NOSE AND LEFT MAIN GEAR IN THE DOWN POSITION. THE RIGHT GEAR REMAINED IN TRANSIT. DIRECTIONAL CONTROL WAS MAINTAINED NEARLY THROUGHOUT THE LANDING ROLL. PRIOR TO THIS FLIGHT, COMPANY MAINTENANCE PERSONNEL HAD INSPECTED THE GEAR IN COMPLIANCE WITH A TELEGRAPHIC MESSAGE FROM THE MANUFACTURER. THE INSPECTION WAS INITIATED BY ONE MAINTENANCE SHIFT AND COMPLETED BY ANOTHER. INSUFFICIENT INFORMATION WAS PASSED BETWEEN THE SHIFTS TO ENSURE THAT GEAR DOOR WAS PROPERLY RE-RIGGED. DURING GEAR EXTENSION, THE DOOR JAMMED PREVENTING COMPLETE EXTENSION OF THE GEAR.
