## Discrepancy

FLIGHT TURNED BACK DUE TO AN UNIDENTIFIABLE ODOR IN THE COCKPIT AND A SMOKE SMELL IN CABIN DURING CLIMB.  DECLARED EMERGENCY BY ATC.  MAINTENANCE FOUND EVIDENCE OF A BIRD STRIKE IN THE NUMBER 1 ENGINE.  ENGINE WAS BORESCOPED AND NO RESTRICTIVE ITEMS FOUND.  RAN BOTH ENGINES TO TAKEOFF POWER, ONE AT A TIME, TO ISOLATE SMELL.  RAN PACKS HOT, WITH NO ODOR FROM EITHER SIDE.  AIRCRAFT OKAY FOR SERVICE.
