Singapore has this week approved the operation of the once-troubled Boeing 737 MAX jets

Singapore’s aviation regulator confirmed it would approve the return to service of the Boeing 737 MAX jets after more than two years of the aircraft being grounded.

Singapore’s approval makes the nation latest country in the Asia Pacific region to approve the planes return to service.

The approval is based on operators including Singapore Airlines complying with airworthiness directives and additional flight crew training requirements, the Civil Aviation Authority of Singapore confirmed in a statement.

Singapore grounded the 737 MAX in March of 2019 following two fatal crashes of the aircraft with operated by other airliners

The approval for its return comes months after the model returned to service in the United States and Europe, and follows more recent lifting of grounding orders in other countries, including Australia, Fiji, Japan, India and Malaysia.

China is the biggest market in the region that has yet to approve the return of the 737 MAX, though Boeing last month conducted test flights in the country.
