National Aviation Preparedness Plan Act of 2022 This bill directs the Department of Transportation (DOT) to develop a national aviation preparedness plan for communicable disease outbreaks, including to (1) create a process to identify appropriate personal protective equipment to reduce the likelihood of exposure to a communicable disease that has the potential to cause an epidemic or pandemic of infectious disease that would constitute a public health emergency of international concern (i.e., a covered communicable disease); and (2) improve coordination between airports, air carriers, and governmental entities with respect to preparing for and responding to communicable disease outbreaks. In developing the plan, DOT must consult with aviation industry and labor stakeholders such as air carriers. The Government Accountability Office must conduct a study assessing the plan, including (1) whether the plan meets the obligations of the United States under international conventions and treaties, and (2) the extent to which the U.S. aviation system is prepared to respond to an outbreak of a covered communicable disease.
