Boeing confirms third final assembly line for 737 in 2015

By:   Stephen Trimble Washington DC  04:16 15 Nov 2012

Boeing has confirmed plans to open a third final assembly line in 2015 to
boost 737 production capacity even beyond the increase to 42 per month
planned in two years.

The third line will initially be used to build the first four flight test
aircraft to support the 737 Max 8 programme in 2015, but will be retained as
a growth line for overall production.

"Eventually we'll use the third line for future rate increases," says Boeing
vice president and general manager Beverly Wyse.

Boeing has previously hinted that it could increase 737 production as demand
continues to surge for single-aisle aircraft.

For example, the company is opening a second line to build wings for the 737
in Renton, Washington, with overall capacity expected to be about 60 shipsets
per month. In September, Spirit AeroSystems chief executive Jeff Turner said
that his existing 737 fuselage factory in Wichita, Kansas, could support
building up to 60 shipsets per month as well.

Boeing also announced that the final design of the 737 Max will include
Rockwell Collins 15.1in-cockpit displays and eliminate a "bump" in the nose
gear door.

The changes were added as the 737 Max cleared the company's "firm concept"
milestone, meaning the configuration and capability of the aircraft defined
in broad terms. Boeing is now working to complete a detailed design of the
737 Max in mid-2013, or shortly after the scheduled engine design freeze of
the CFM Leap-1B in April.

Boeing expects the 737 Max to consume 13% less fuel than the original version
of the next-generation 737NG delivered in 1997.

Replacing the CFM56-7B for the Leap-1B engines offers the most significant
fuel improvement. Other significant changes includes the addition of
split-tip winglets, a redesigned tail cone, electronic bleed air system and
fly-by-wire spoiler controls.

The larger diameter of the Leap-1B engines forced Boeing to extend the nose
gear by 20cm, resulting in a "bump" in the nose gear door. Boeing, however,
adopted narrower radial tires for the nose gear and deepened the wheel well,
allowing the bump to be eliminated, says Michael Teal, chief project engineer
for the 737 Max.

The programme remains on track to deliver the first 737 Max 8 in 2017, but
"there may be opportunity" to accelerate the schedule, Wyse says.

Boeing adds tweaks to final 737 Max configuration

By:   Stephen Trimble Washington DC  04:08 15 Nov 2012

Boeing has finalised the design and production plan for the 737 Max several
months before beginning the detailed design phase of the re-engined and
updated single-aisle.

The "firm concept" milestone adds three new tweaks to the final configuration
- large format cockpit displays, an electronic bleed air system and the
elimination of a blister fairing in the nose gear door, Boeing says.

Of the changes, the electronic bleed air system may have the most impact on
the performance of the 737 Max. It is usually adopted to optimise the cabin
pressurisation and de-icing systems, leading to better fuel efficiency.

Boeing has promised up to a 13% reduction in fuel burn on the 737 Max, with
the integration of the CFM Leap-1B turbofan making the largest contribution.
The improvements also include a split-tip winglet, redesigned tail cone and a
fly by wire spoiler system.

The larger diameter of the Leap-1B fan, which measures 175cm (69.4in),
required extending the nose gear by 20.3cm. Boeing initially designed a small
"bump" in the nose gear door to accommodate the extension, but subsequently
found ways to remove it.

Boeing also has decided to add a 737 Max transition line to assemble the
first several aircraft. Assembly will then shift to the existing 737
production lines in Renton, Washington, Boeing says.

The 737 Max, which has amassed a backlog of 909 orders, is on track for first
delivery in 2017, Boeing says.
