Seattle - The US Federal Aviation Administration (FAA) certified 737 MAX 9, Boeing announced on Friday, February 16. Commercial commissioning of the aircraft is planned with Indonesian carrier Lion Air.

Less than a year after the MAX 8, the MAX 9 becomes the second member of the MAX family to be declared suitable
for service by the FAA. The certification marks the culmination of a flight test campaign conducted with two prototypes.

The first prototype made its maiden flight on April 13, 2017. At a length of 42.16 meters, the MAX 9 measures 2.64 meters longer than the MAX 8. Its 35.9 meters wingspan is identical to all other members of the family.

The standard configuration in two-class provides 178 to 183 seats, but the single-aisle is designed to carry a maximum of 220 passengers in a single class configuration.

With three additional rows of seats compared to the 737 MAX 8, the MAX 9 offers operators an additional capacity while maximizing profitability within their network,
specifies the manufacturer.

The radius of action might be extended to 3.550 NM thanks to the additional fuel tank. Like all other MAXs, the MAX 9 is powered by CFM International's LEAP-1B engines and is
equipped with marginal winglets. The cabin is equipped with the Boeing Sky Interior

Boeing is now preparing to deliver the first MAX 9 series to Lion Air. The Indonesian low-cost operator has ordered a total of 201 MAX in various variants and has already received eight 737 MAX 8s.

In addition to the MAX 8 and 9, the MAX family also includes the MAX 7, which made its first factory roll-out at Renton earlier this month, of which commissioning is scheduled for 2019.

Last week, Boeing also completed the final configuration of the fourth and largest variant of the family, the MAX 10, whose first commercial flight is not expected earlier than 2020.

Launched in 2011, the MAX program has so far accumulated more than 4,300 firm orders from 93 customers.
