A Category 1 rating means the country’s civil
aviation authority complies with ICAO standards.
A Category 2 rating means a country either lacks
laws or regulations necessary to oversee air
carriers in accordance with minimum
international standards, or that its civil
aviation authority equivalent to the FAA for
aviation safety matters is deficient in one or
more areas, such as technical expertise, trained
personnel, record keeping or inspection
With the International Aviation Safety
Assessment (IASA) Category 1 rating, Israeli air
carriers can add flights and service to the
United States and carry the code of U.S.
With the Category 2 rating, Israeli air
carriers were allowed to maintain existing
service to the United States, but could not
establish new services.
The United States Federal Aviation
Administration (FAA) established the IASA
program through public policy in August of 1992.
FAA's foreign assessment program focuses on a
country's ability, not the individual air
carrier, to adhere to international standards
and recommended practices for aircraft
operations and maintenance established by the
United Nation's technical agency for aviation,
the International Civil Aviation Organization
