The FAA’s International Air Safety Assessment (IASA) program determines whether a country and its airlines will be allowed to fly into the United States.
IASA inspectors determine whether entire countries, rather than specific airlines, meet the international standards set by the United Nations.
Airlines from countries that fail to pass inspections will not be allowed to launch new flights into the US.
Each country is evaluated by the FAA on eight “critical elements” including its primary aviation legislation, specific operating regulations, state civil aviation system and safety oversight functions, technical personnel qualification and training, and resolution of safety concerns.
Countries deemed by the FAA to have failed to comply with ICAO standards will not be allowed to launch new service into the US. Failing countries with existing service will be allowed to continue its US flights but under heightened FAA surveillance. In addition, any expansion or alterations to their US operations will not be permitted.
