These safety standards are set by the International Civil Aviation Organization (ICAO), based on an assessment of each country’s civil aviation authority.
As a result, the FAA has assigned both Curaçao and Sint Maarten an International Aviation Safety Assessment (IASA) Category 2 rating. With a Category 2 rating, Curaçao and Sint Maarten air carriers will not be allowed to establish new service to the United States, but can continue existing service. Both countries were previously part of the Netherlands Antilles, which had a Category 1 rating.
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 procedures.
As part of the FAA’s IASA program, the agency assesses the civil aviation authorities of all countries with air carriers that operate or have applied to fly to the United States and makes that information available to the public. The assessments determine whether or not foreign civil aviation authorities are meeting ICAO safety standards, not FAA regulations.
Countries with air carriers that fly to the United States must adhere to the safety standards of ICAO, the United Nations’ technical agency for aviation that establishes international standards and recommended practices for aircraft operations and maintenance.
