What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) While in cruise-descent to FL210, right after the "eicas" "icing" caption illuminated, the cockpit and cabin filled up with smoke and soot. The captain declared an emergency, and landed uneventfully in roa, VA. The oxygen masks were not deployed, and there was no emergency evacuation. There was no evidence of fire, and no immediately apparent source for the smoke and soot. Maintenance personnel later determined that the left air conditioning machine (acm) had seized, causing the smoke and soot. The system was deferred, and the #1 acm was later changed at a maintenance base.
