## Discrepancy

ON TAKEOFF FROM DSM, THE LT PACK TRIPPED AND THE LT DUCT OVERHEAT LIGHT ILLUMINATED.  THIS WAS ACCOMPAINED BY THE USUAL ODOR OF A PACK OVERHEATING  AND SMOKE IN THE COCKPIT.  QRH PROCEDURES ELIMINATED THE SMOKE & REESTABLISHED THE LT PACK.  GIVEN THE OUTSIDE AIR TEMPERATURE AT DSM OF 21 DEGREES C, FOUND COOLING FAN GETTING POWER  BUT FAN NOT OPERATING JUST HUMMING WITH A BURN SMELL COMING FROM FAN.  R & R LT PACK COOLING FAN REF AMM 21-56-091-4.
