What was found
WHEN THE CREW WAS DOING THEIR PREFLIGHT CHECKS THEY SMELLED A SMOKE ODOR COMING FROM THE CABIN. THE CREW REPORTED THE ISSUE TO MAINTENANCE CONTROL AND THEY DISPATCHED LOCAL MAINTENANCE TO THE AIRCRAFT. MAINTENANCE COULD NOT DUPLICATE THE SMOKE ODOR BUT DID GET A RIGHT HAND PACK OVERHEAT AND THE RIGHT HAND PACK WAS PLACED ON MEL.
