## Discrepancy

DURING INITIAL CLIMBOUT, CREW REPORTED A HOT HYDRAULIC ODOR BEING EMITTED FROM THE AIR CONDITIONING SYSTEM.  BOTH THE FORWARD AND THE REAR LAVATORY SMOKE DETECTORS SOUNDED.  ODOR DISSIPATED AND ALARMS SILENCED QUICKLY BUT THEN IT ALL REPEATED DURING APPROACH FOR LANDING AT DESTINATION.  MAINTENANCE DISCOVERED THREE HYDRAULIC LINE LEAKS.  THE A SYSTEM RETURN LINE, THE SPOILER SHUTOFF VALVE LINE, AND THE LEFT ANTI-SKID VALVE FITTING, WERE PROVIDING FLUID TO BE INGESTED BY THE APU.  TWO O-RINGS AND A TEMPORARY LINE WERE INSTALLED AND THE ACFT RETURNED TO SERVICE.
