An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine will examine the air quality and any risk of persistent and accidental fume or smoke events in the cabin of passenger aircraft operated under part 121 of title 14, Code of Federal Regulations.

Specifically, the committee will examine:

• the Federal Aviation Administration report on the feasibility, efficacy, and cost-effectiveness of certification and installation of systems to evaluate bleed air quality, as required in the FAA Reauthorization Act of 2018;
• information about the incidence of fume and smoke events (both regularly and irregularly occurring), and whether such events are more frequent during different phases of operations such as ground operations, taxiing, take off, cruise, and landing;
• the frequencies, durations, and likely causes of the events;
• the air contaminants present during smoke and fume events;
• the health impacts and risks of fume or smoke events on flight crews, including flight attendants and pilots, and passengers.
