After a review of Thailand’s aviation safety and maintenance practices, the country has failed to secure a US FAA Category 1 rating.
The Civil Aviation Authority of Thailand (CAAT) reported that a four-person team from the US FAA conducted an audit on the oversight of aviation safety and maintenance standards in mid-February, which found 26 deficiencies that need to be rectified before the country’s rating can be upgraded.
Once all the 26 deficiencies are addressed, the CAAT further stated a new audit can be done.
Thailand was initially downgraded to Category 2 status in December of 2015 after an ICAO audit. No new flights can be established between the two countries until it gets upgraded to Category 1.
Within the last few years, Thai Airways was the only airline serving the US-Thailand market direct market with flights to Los Angele. Those flights have since been discontinued in 2015.
The ICAO audit results also impacted the ability of Thai carriers to start flights to regional destination.
