## Discrepancy

(CAN) THE ACFT ARRIVED WITH A HYDRAULIC LEAK ON THE OUTBOARD SIDE OF THE LEFT NACELLE.  INVESTIGATION REVEALED THAT THE LEAK WAS COMING FROM THE LT OUTBOARD ROLL SPOILER ACTUATOR, P/N A44700-009, S/N 0377.  THIS PART HAS A TSR OF 8451 HRS AND CSR OF 8462 CYCLES.  TSO/TSN IS 52553 HRS AND CSN/CSO IS 58223 CYCLES.  THE ACTUATOR HOUSING AT THE PISTON END CAP WAS FOUND FRACTURED AND DISLOCATED FROM THE ACTUATOR.  IT WAS HELD ATTACHED TO THE ACTUATOR ONLY BY LOCKWIRE.  THE LT OUTBOARD ROLL SPOILER ACTUATOR WAS REPLACED AND THE SYSTEM CHECKED SERVICEABLE.  IT SHOULD BE NOTED THAT THE OUTBOARD ROLL SPOILERS ARE DISABLED ABOVE 140 KTS AND THE HYDRAULIC PRESSURE SUPPLY IS REMOVED.  THERE IS HOLD DOWN PRESSURE SUPPLIED TO THE ACTUATOR AT ALL TIMES.
