## Discrepancy

BEFORE FLIGHT, THE CREW NOTED A CAS MESSAGE FOR LT BLEED SOV FAIL AND LT PACK FAIL.  THE CREW ABORTED THE TAKEOFF AND RETURNED TO THE GATE.  MX INSPECTED AND OPERATED THE SYSTEM BUT COULD NOT DUPLICATE THE DISCREPANCIES.  MX REPLACED THE LT PRESSURE REDUCING VALVE (BOV) FOR TROUBLESHOOTING AND RETURNE THE AIRCRAFT TO SERVICE. (K)
