## Discrepancy

15 MINUTES AFTER DEPARTURE, CREW REPORTED THAT THE NR 1 HYDRAULIC SYSTEM FLUID QUANTITY DROPPED TO LESS THAT ONE US QUART, AND PRESSURE WENT TO ZERO.  THE AIRCRAFT RETURNED TO BASE UPON WHICH MAINTENANCE DISCOVERED THAT THE RT INBOARD FLIGHT SPOILER ACTUATOR HOUSING HAD CRACKED ON THE BODY SURROUNDING THE FORWARD END OF THE ACTUATOR SLEEVE.  A BROKEN PIECE OF THE ACTUATOR BODY WAS DISLODGED AND FELL INTO THE AFT SECTION OF THE REAR SPAR ON THE RT WING.  MAINTENANCE REPLACED THE SPOILER ACTUATOR AND FUNCTION CHECKED IT PER AMM 27-14-05.  SYSTEM WAS BLED AND LEAK CHECKED SERVICEABLE.
