Since October 19, the FAA is conducting a technical audit of the AFAC (Mexican Federal Agency of Civil Aviation), it is being done remotely. Back in 2010, this audit degraded Mexico to category 2, which means, Mexican air carriers cannot establish new service to the United States, although they are allowed to maintain existing service.
As part of the FAA’s International Aviation Safety Assessment (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.
If Mexico has improved the standards and recommended practices since then, a category 1 rating could be awarded, which means, AFAC complies with ICAO standards and recommended practices for aircraft operations and maintenance.
