Boeing has announced that the 737 MAX 9 has received an amended type certificate (ATC) from the US Federal Aviation Administration (FAA), officially certifying the aircraft for commercial service.
This certification marks the culmination of a flight test programme that began in March 2017 with two Boeing flight test airframes.
The manufacturer is now in the final stages of preparing the MAX 9 for its first delivery to launch customer Lion Air Group.
The 737 MAX 9 has three additional seat rows compared to the 737 MAX 8 and is designed for a capacity of up to 220 passengers and a maximum range of 3,550 nautical miles. It also incorporates such notable features as the latest CFM International LEAP-1B engines, Advanced Technology winglets, Boeing Sky Interior, and large flight deck displays.
