Boeing begins final assembly of the first 737 MAX

Boeing (Chicago, Seattle and Charleston) 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.

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

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.

Boeing will build the first 737 MAXs exclusively on the new production line in the Renton factory. Once mechanics prove out the production process, the team will extend MAX production to the other two final assembly lines in Renton.

The 737 MAX team remains on track to roll out the first completed 737 MAX by the end of the year and fly it in early 2016. Launch customer Southwest Airlines is scheduled to take delivery of the first 737 MAX in the third quarter of 2017. In total, the 737 MAX family has 2,869 orders from 58 customers worldwide.

Boeing brings the first 737 MAX fuselage to Renton

Boeing 1st Boeing 737 MAX Fuselage

Boeing (Chicago, Seattle and Charleston) on Friday (August 21) brought the first 737 MAX fuselage to the Renton, WA plant. The fuselage was built in Wichita, KS and transported by rail to the Washington State plant.

Boeing explains the production of the Boeing 737 over the years:

Boeing logo (medium)

The first 271 737s were built in Seattle at Boeing Plant 2, just over the road from Boeing Field, (BFI). However, with the sales of all Boeing models falling and large scale staff layoffs in 1969, it was decided to consolidate production of the 707, 727 and 737 at Renton just 5 miles away. In December 1970 the first 737 built at Renton flew and all 737s have been assembled there ever since.

However not all of the 737 is built at Renton. For example, since 1983 the fuselage including nose and tailcone has been built at Wichita and brought to Renton by train. Also much of the sub-assembly work is outsourced beyond Boeing.

Production methods have evolved enormously since the first 737 was made in 1966. The main difference is that instead of the aircraft being assembled in one spot they are now on a moving assembly line similar to that used in car production. This has the effect of accelerating production, which not only reduces the order backlog and waiting times for customers but also reduces production costs. The line moves continuously at a rate of 2 inches per minute; stopping only for worker breaks, critical production issues or between shifts. Timelines painted on the floor help workers gauge the progress of manufacturing.

When the fuselage arrives at Renton, it is fitted with wiring looms, pneumatic and air-conditioning ducting and insulation before being lifted onto the moving assembly line. Next, the tailfin is lifted into place by an overhead crane and attached. Floor panels and galleys are then installed and functional testing begins. In a test called the “high blow”, the aircraft is pressurised to create a cabin differential pressure equivalent to an altitude of 93,000 feet. This ensures that there are no air leaks and that the structure is sound. In another test, the aircraft is jacked up so that the landing gear retraction & extension systems can be tested. As the aircraft moves closer to the end of the line, the cabin interior is completed – seats, lavatories, luggage bins, ceiling panels, carpets etc. The final stage is to mount the engines. There are approximately 367,000 parts on a 737 NG.

The present build time is now just 11 days (5,500 airplane unit hours of work) with a future target of 6 days (4,000 airplane unit hours of work). In Dec 2005 a second production line was opened to increase the production rate to 31 aircraft a month. By 2007 there was a three year waiting list for new 737s, and an order backlog of over 1,600 aircraft. A third production line is under construction dedicated to the MMA order.

After construction they make one flight, over to BFI where they are painted and fitted out to customer specifications. It takes about 200ltrs (50USgallons) of paint to paint a 737. This will weigh over 130kg (300lbs) per aircraft, depending on the livery. Any special modifications or conversions (eg for the C40A, AEW&C or MMA) are done at Wichita after final assembly of the green aircraft. Auxiliary fuel tanks and specialist interiors for VIP aircraft are fitted by PATS at Georgetown, Delaware.

The fuselage is a semi-monocoque structure. It made from various aluminium alloys except for the following parts.

  • Fiberglass: radome, tailcone, centre & outboard flap track farings.
  • Kevlar: Engine fan cowls, inboard track faring (behind engine), nose gear doors.
  • Graphite/Epoxy: rudder, elevators, ailerons, spoilers, thrust reverser cowls, dorsal of vertical stab.

Different types of alluminium alloys are used for different areas of the aircraft depending upon the characteristics required. The alloys are mainly aluminium, zinc, magnesium & copper but also contain traces of silicon, iron, manganese, chromium, titanium, zirconium and probably several other elements that remain trade secrets. The different alloys are mixed with different ingredients to give different properties as shown below:

Fuselage skin, slats, flaps – areas primarily loaded in tension – Aluminium alloy 2024 (Aluminium & copper) – Good fatigue performance, fracture toughness and slow propagation rate.

Frames, stringers, keel & floor beams, wing ribs – Aluminium alloy 7075 (Aluminium & zinc) – High mechanical properties and improved stress corrosion cracking resistance.

737-200 only: Bulkheads, window frames, landing gear beam – Aluminium alloy 7079 (Aluminium & zinc) Tempered to minimise residual heat treatment stresses.

Wing upper skin, spars & beams – Aluminium alloy 7178 (Aluminium, zinc, magnesium & copper) – High compressive strength to weight ratio.

Landing gear beam – Aluminium alloy 7175 (Aluminium, zinc, magnesium & copper) – A very tough, very high tensile strength alloy.

Wing lower skin – Aluminium alloy 7055 (Aluminium, zinc, magnesium & copper) – Superior stress corrosion.

Outsourcing

Many components are not built by Boeing but are outsourced to other manufacturers both in the US and increasingly around the world. This may be either for cost savings in production, specialist development or as an incentive for that country to buy other Boeing products. Here is a list of some of the outsourced components:

  • Fuselage, engine nacelles and pylons – Spirit AeroSystems (formerly Boeing), Wichita.
  • Slats and flaps – Spirit AeroSystems (formerly Boeing), Tulsa.
  • Doors – Vought, Stuart, FL.
  • Spoilers – Goodrich, Charlotte, NC.
  • Vertical fin – Xi’an Aircraft Industry, China.
  • Horizontal stabiliser – Korea Aerospace Industries.
  • Ailerons – Asian Composites Manufacturing, Malaysia.
  • Rudder – Bombardier, Belfast.
  • Tail section (aluminium extrusions for) – Alcoa / Shanghai Aircraft Manufacturing, China.
  • Main landing gear doors – Aerospace Industrial Development Corp, Taiwan.
  • Inboard Flap – Mitsubishi, Japan.
  • Elevator – Fuji, Japan.
  • Winglets – Kawasaki, Japan.
  • Forward entry door & Overwing exits – Chengdu Aircraft, China.
  • Wing-to-body fairing panels and tail cone – BHA Aero Composite Parts Co. Ltd, China.
