## Discrepancy

AFTER TAKEOFF DURING CLIMB PILOT TRIED TO PUT GEAR HANDLE UP ALL LIGHTS INDICATED GEAR UP BUT HANDLE FAILED TO RETURN TO NEUTRAL.  PILOT THEN PUT GEAR HANDLE DOWN, GOT GREEN LIGHTS INDICATING GEAR DOWN AND LOCKED, BUT AGAIN GEAR HANDLE DID NOT RETURN TO NEUTRAL.  HE FLEW BY THE TOWER TO MAKE SURE THAT GEAR WAS DOWN AND LOCKED.  DURING TROUBLESHOOTING, FOUND THAT THE DOORS WOULD NOT GO UP IN FLIGHT.  FOUND THAT THE HYDRAULIC FLUID WAS BEING DUMPED OVERBOARD.  REPLACED THE HYDRAULIC POWERPACK AND GOT THE FLUID TO STOP GOING OVERBOARD.
