## Discrepancy

DURING TAKEOFF OF FLIGHT, THE CREW REPORTED LOW PRESSURE BLEED SOV FAIL CAS MESSAGE AFTER POWER UP FOR TAKE OFF.  THE CREW ABORTED THE TAKEOFF AND RETURNED TOT HTE GATE.  MECHANIC INSPECTED THE SYSTEM AND REPLACED LT PACK FLOW CONTROL VALVE BUT THE SYSTEM STILL OPS CHECKED BAD.  MECHANIC THEN SWAPPED THE LT AND RT LOW PRESSURE VALVES (PRSOV) AND OPS CHECKED GOOD.  MECHANIC RETURNED THE AC TO SERVICE.  AS OF 05/11/05, PROBLEM HAS NOT RETURNED.  (K)
