What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
After descending below 10,000 feet on arrival into mci, the flight attendants reported smoke and fumes in the cabin. Shortly thereafter, the crew began to smell very strong fumes on the flight deck. The flight deck crew donned oxygen masks. The flight attendants were informed that the aircraft would be landing immediately and to prepare for a possible evacuation. The captain declared an emergency and landed at mci. While running checklists and after turning off the recirc fans, the crew received a "pack 2 fail" eicas message followed by a "pack off" message. The flight attendants informed the crew that the smoke stopped and that the fumes were dissipating. The aarf crew inspected the aircraft and observed no unusual smoke. They detected no high temperature reading with their thermal equipment. The crew obtained taxi instructions and began to move. The flight attendants reported increasing fumes. At that point, the crew initiated an emergency evacuation via the slides.
