## Discrepancy

AFTER THE AIRCRAFT TOOK OFF AND THE CREW SELECTED GEAR UP THE 'UNSAFE' GEAR WARNING LIGHTS REMAINED ON.  THE CREW SELECTED DOWN AND OBTAINED 3 GREEN LIGHTS AND RETURNED TO BASE.  MAINTENANCE WAS ABLE TO REPEAT THE PROBLEM ON THE GROUND ON GEAR SWINGS.  THE UPLOCK HOOKS WERE NOT FULLY ENGAGING ON THE UPLOCK ROLLERS.  THE MECHANISMS WERE CLEANED AND LUBRICATED AND THE GEAR SWINGS WERE SERVICEABLE.  AIRCRAFT RETURNED TO SERVICE.
