Renton - Boeing began the final assembly of the 737 MAX 7, the smallest variant of the 737 MAX family.

The US manufacturer said on November 22 on its Twitter account that the final assembly of the first 737 MAX 7 has officially started in the Renton plant. After production of the first wing spar in early October, the nose and fuselage sections arrived at the factory.

The 737 MAX 7 is configured to carry 138 passengers in standard two-class layout, and up to 172 passengers in a single-class.

About 4 meters shorter than the 737 MAX 8, the 737 MAX 7 can carry 138 passengers in standard two-class layout, and up to 172 passengers in a single-class. Equipped with CFM International's LEAP-1B engines, the 737 MAX 7 has a range of 3,825 nm (7,080 km).

The 737 MAX now exceeds 4,000 firm orders, but within this family, the MAX 7 is a modest success. Customers of this variant are Southwest Airlines (30 units), WestJet (23), Canada Jetlines (5) and Air Lease Corporation (5). The first delivery is expected in January 2019 for Southwest Airlines.

In addition to the MAX 7, Boeing also offers the MAX 8, 40 of which have been delivered to date. Currently under development, the MAX 9 is scheduled to come into service in 2018. It will be followed in 2019 by the MAX 200, the high-density version of the MAX 8, and in 2020 by the MAX 10.
