Boeing employees in Renton, Washington, have started final assembly on schedule of the first 737 MAX 8, the first member of Boeing's new, more efficient single-aisle family.

"We continue to meet our plan on the 737 MAX program thanks to the dedication of our employee team and our suppliers," said Keith Leverkuhn, vice president and general manager, 737 MAX program, Boeing Commercial Airplanes. "We have a lot more work still ahead of us but we're very pleased with our progress to date."

After the first fuselage arrived on August 21 from Spirit Aerosystems in Wichita, Kan, mechanics began installing flight systems and insulation blankets.

"It's an honor. There is only one crew that gets to be that first crew that builds that airplane. I'm really excited," said Sean Christian, 737 MAX Electrical team lead. 

Crews next moved the fuselage to the wing-to-body join position on the new production line where the first MAXs will be built. Mechanics then attached the wings to the body of the airplane.

The wings feature Boeing's new Advanced Technology winglets. Designed exclusively for the 737 MAX, they will give customers up to 1.8 percent additional fuel-efficiency improvement over today's inline winglet designs.

"Seeing the new winglet design we validated in the wind tunnel years ago now on the first new airplane is incredible," said Leverkuhn. "It's just one of the features that differentiate the 737 MAX and make it an amazingly fuel-efficient machine."
