Aprx 3 mi further south, other witnesses saw the acft make a 180 deg turn back twd the arpt. They rprtd the eng was running rough & they believed black smoke was trail- ing from the lower eng area. As the acft contd twd the arpt, others heard &/or saw the acft. Some rprtd the eng was running very rough. Others closer to the arpt saw no smoke & svrl thought the eng was not running.
