Seattle - Boeing plans to assemble 57 Boeing 737 jets per month from June to meet the soaring global demand for its best-selling airliner. The company also invests in new technologies to ramp up its 787 production.

Boeing aims to increase its production rate from 52 single-aisle jets to 57 per month from June 3rd. The manufacturer suffered from engine delivery delays from suppliers last year, which forced the company to postpone aircraft deliveries to its customers.

The delayed engines from the Franco-American engine manufacturer CFM International caused the assembled 737s to remain parked on the Renton factory for months.

This year, Boeing has sent more of its employees to the CFM International to help the engine supplier to speed up the delivery of the Leap-1B engines for the 737 Max program.

We still have work to do to get CFM to be supporting our 52-a-month production rate and having those systems synchronized; and even more work to do to get them to 57 a month,

said Boeing CEO Dennis Muilenburg.

By us getting deeper into their factories, it’s going to give us better insights on long-lead items and frankly to help us do best practice sharing between Boeing and them, which is part of how we operate,

he also added.

Spirit AeroSystems, which produces about 70 percent of the Boeing 737 airframe, was also mentioned by Boeing as the cause of delays last year. On February 1st, the supplier said that it has been preparing its lines to support the assembly of 57 Boeing 737 per month.

The Boeing 737 Family is the top-selling product line of the company. The extra five aircraft means more profit for the manufacturer.

Boeing feels the pressure from its European rival Airbus, which is about to assemble 60 aircraft per month of its best-selling single-aisle jets from the A320 Family.

On the other hand, Boeing is also preparing to boost the production of its new generation 787 jets from 12 aircraft to 14 per month. For this, the manufacturer is equipping its mechanics with new tools, which transforms them into half-man, half-robot bionic workers by increasing their strength and speed.

“You have the capability of a robot and the capability of a human being melded together,” said Christopher Reid, a Boeing associate who was previously designer of NASA's spacesuits.

Boeing expects to complete the production increase on the 787 FAL in the second quarter of the year.
