The U.S. Federal Aviation Administration (FAA) announced that the Kingdom of Thailand does not comply with International Civil Aviation Organization (ICAO) safety standards and has been assigned a Category 2 rating based on a reassessment of the country’s civil aviation authority.
A Category 2 International Aviation Safety Assessment (IASA) rating means that the country either lacks laws or regulations necessary to oversee air carriers in accordance with minimum international standards, or its civil aviation authority is deficient in one or more areas, such as technical expertise, trained personnel, record-keeping, or inspection procedures. With a Category 2 rating, Thailand’s carriers can continue existing service to the United States. They will not be allowed to establish new service to the United States.
Thailand was assigned an initial Category 2 rating in 1996 and received a Category 1 rating in 1997. Reassessments of Thailand in 2001 and 2008 continued the Category 1 rating. A reassessment in July 2015 found that Thailand did not meet international standards.
As part of it’s Universal Safety Oversight Audit Programme (USOAP), ICAO audited the Thai civil aviation authority in 2005.
The results of this audit showed that the country scored below world average in their oversight. In March 2015 ICAO identified a significant safety concermn with respect to the ability of the authorities to properly oversee it’s airlines.
