## Discrepancy

PILOTS REPORTED THAT THE RT PACK PRODUCED SMOKE AND A BURNED ODOR ONLY WHILE ON THE GROUND.  IN THE AIR IT WAS NORMAL. MAINTENANCE FOUND THAT THE GROUND COOLING FAN WOULD WORK FOR A MINUTE AND THEN QUIT. ORIGINALLY PLACED ON MEL AND THEN MAINTENANCE REMOVED AND REPLACED THE RECIRCULATING FAN PN AE1711AA0 SN ON 224 SN OFF 711. IAW MM 21-25-02. THE OPERATIONAL CHECK WAS GOOD.
