## Discrepancy

AFTER TAKEOFF & LG RETRACTION, PILOT NOTICED HYD POWER PACK RUNNING EXCESSIVELY, THEN LOW HYD WARNING LIGHT CAME ON.  MANUALLY EXTENDED THE LG & RETURNED TO ORIGINAL AIRPORT FOR AN UNEVENTFUL LANDING.  AFTER LANDING, HYD FLUID WAS OBSERVED LEAKING FROM THE HYD POWER PACK WING PANEL & ON THE BACK OF THE WING.  LOCATED THE SOURCE OF THE FLUID LEAK TO THE FWD B NUT ON LG RETRACT SOLID LINE, PN 114-580047-1.  THIS FITTING WAS TIGHTENED & A CONICAL SEAL WAS INSTALLED TO ELIMINATE LEAKAGE.  THE LG WAS MANUALLY CYCLED, THE SYS SERVICED & THE ACFT WAS RETURNED TO SERVICE.  INVESTIGATION CONTINUES THROUGH THE COMPANY SMS REPORTING & ANALYSIS SYS.
