What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Flight attendant reported smoke in the cabin during taxi. Aircraft was stopped, main cabin door opened. Fire/rescue was called and inspected the aircraft inside and out. Nothing was noted. Since the fumes persisted, the passengers were deplaned via the main cabin door and bussed to the terminal. Comair maintenance discovered that the right air cycle machine had seized, resulting in the smoke and fumes.
