An Endeavor Air Canadair CRJ-200 on behalf of Delta Airlines, registration N8847A performing flight 9E-5370/DL-5370 from Columbus,GA to Atlanta,GA (USA) with 34 passengers and 3 crew, was enroute when the crew received indication of a possible oil leak at the APU. Descending through 8000 feet into Atlanta an odour described like a sweet alcoholic sanitizer followed by visible smoke developed on board, soon after the crew reported smoke in the cockpit telling ATC there was quite a bit of smoke at the interior of the aircraft, they would stop on the runway for an inspection by emergency services. The aircraft landed on Atlanta’s runway 28 a few minutes later and stopped on the runway. The crew told ATC they believed the source of the smoke was in the aft area possibly the APU, emergency services reported there was no smoke or other hazard visible from the outside. The crew subsequently decided to taxi to the apron. A number of crew were taken to a hospital.
