## Discrepancy

FLT 4063 - CREW NOTICED SMOKE IN AIRCRAFT DURING TAXI.  THERE WERE NO ASSOCIATED PACK, DUCT, OR BLEED INDICATION WARNING LIGHTS ILLUMINATED.  MAINTENANCE RAN BOTH NR 1 AND NR 2 ENGINES FOR 15 MINUTES, CYCLED BOTH PACKS, AND SHUT BLEEDS ON AND OFF.  MAINTENANCE ALSO INSPECTED ELECTRIC BAY, ACM HOSE AND ENGINE BLEEDS FOR OIL THEN RAN ENGINES NR 1 AND NR 2 FOR 15 MINUTES AGAIN.  MAINTENANCE COULD NOT DUPLICATE DISCREPANCY.  AIRCRAFT RETURNED TO SERVICE.  (X)
