Production 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.
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.

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:

31 Jan 2013 - Boeing ramps up 737 production to 38 airplanes per month
RENTON, Wash., 31 Jan. 2013. Boeing (NYSE:BA) workers are now assembling Next-Generation 737 at a rate of 38 airplanes per month in its Renton, Wash., facility. Boeing has grown production of the 737 by more than 20 percent, from 31.5 to 38 airplanes a month, over the past two years. Boeing’s executive leadership anticipates another increase in 2014, to a rate of 42 airplanes a month. "We have more hard work ahead of us, but we are well on our way to another successful production rate increase," says Beverly Wyse, vice president and general manager of the 737 program. Employee teams have been instrumental in reducing 737 production flow by developing and implementing innovative efficiency improvements, says a spokesperson. The first Next-Generation 737 built at the new rate is scheduled to be delivered in the second quarter of this year.
14 Jul 2011 - Boeing considering production rate of 60 aircraft a month
Boeing is once again contemplating increasing the production of its Renton 737 airliner production lines, its commercial airplanes chief executive says. Jon Ostrower, writing on FlightGlobal.com, says Boeing Commercial Airplanes CEO Jim Albaugh has asked Boeing production executives to gather information about what changes would be necessary at the plant and among suppliers to raise production to 60 737s a month. That's nearly twice the present 31.5 planes a month the plant makes now. Boeing has already scheduled several stepped rate increases to take that production to 42 monthly by 2014. Boeing's two existing production lines in Renton are capable of producing 21 planes a month each when suppliers are able to furnish parts and subassemblies at that rate. The plant has a third 737 production line that is now dedicated to building militarized versions of the 737 for the U.S. and foreign navies. Those planes are equipped with sensors and weaponry to hunt submarines. That third assembly line could theoretically be equipped to also produce commercial airliners. Albaugh told the National Aeronautic Association in a speech this week that if the company can figure out how to build that many planes a month, Boeing could sell them. Albaugh is fresh from a meeting with American Airlines which may order up to 250 single-aisle jets from either Boeing or Airbus. American has been a Boeing-only customer in recent years. At present production rates, the company, however, is sold out through 2016 for the 737. Boeing wants to offer big customers such as American earlier delivery slots to win their business.

Boeing says it will build 500 737NGs annually, beginning in 2014, in a strong endorsement of the strength of its supply chain and airlines to withstand the threat of high fuel prices and economic uncertainty in Europe and the U.S.
The new rate, 42 per month, is the fourth boost in the past two years and will be absorbed by the second final assembly line at Boeing’s Renton facility, south of Seattle. The company’s 737 backlog is more than 2,100 aircraft.
Line One is already carrying its share of that rate at 21 per month, so the second line will absorb the increase from its current 10.5.
For several years, Boeing has been concerned that frustration over long lead times would drive its customers to other products unless it boosts production rates. That concern is not aimed just at Airbus—Bombardier in Canada, Comac in China and Irkut in Russia are developing 737 competitors.
Meanwhile, legacy airlines have learned to manage their way through economies that continue to remain weak so well that order rates for 737s remain strong.
The improvement package includes cabin upgrades of larger baggage bins and better lighting. The combination has helped sustain demand, says 737 General Manager and Boeing VP Beverly Wyse. Sixty-four customers have ordered the upgrades, she says.
Renton went to a 31.5-per-month rate in 2009, or not quite 1.5 airplanes per day, given an average 22 work days per month. The rate is expected to reach 35 per month early next year, 38 per month in the second quarter of 2013 and the 42 rate in the first half of 2014. The 31.5 rate is a record pace, so each increase sets a new standard for Boeing’s commercial production.
Overall, Boeing is boosting total airplane production 40% by 2013, the other big jump coming on its 777 widebody line.
Airbus previously announced a shift to 42 per month. Boeing officials say the Airbus figure was about the equivalent of 38 per month because the Europeans are factoring in that factories are closed in August.
Boeing does not build the 737 fuselage—Spirit AeroSystems does in a factory previously owned by Boeing in Wichita. The 42 rate has been under discussion for months. The big concern was not whether Boeing’s own workers and factories could keep up the pace, but whether the supply chain could do so. “We have worked very closely with our supply chain ... to ensure we can increase rate in an efficient and responsible fashion,” says Wyse. “We believe that many of the capital investments and production system changes made for 38 airplanes per month will already position us to build 42.”
The Renton facility dates to World War II but has been so thoroughly modernized over the past decade that it can support 737 production rates as high as 63 aircraft per month, Wyse says.
31 Aug 2010 - Upping 737 output further may be too costly
Chief Financial Officer James Bell said Tuesday that raising production rates for the 737 jetliner to 40 a month from a planned 35 could be too costly to implement. Speaking at an analyst conference in New York, Bell said the manufacturer can lift monthly 737 output to 35 without a "significant amount of capital expense," but such spending would have to increase if the rate were to go higher. Furthermore, there is concern that current market demand may not be sustainable, Bell said. In other areas, profit margins among Boeing's civil aircraft lines are "as close to what we can do," Bell said. However, if 737 rates are lifted, it could provide a margin benefit for other models. Meanwhile, Boeing said last week it would have to delay the first delivery of the 787 to early next year, but Bell said costs associated with the new delay can be absorbed by the company.
18 May 2010 - Boeing to increase 737 production rate to 34 a/c per month
Boeing today announced that it will increase production rates on the Next-Generation 737 program to 34 airplanes per month in early 2012. The planned rate increase is aimed at satisfying continued strong demand for the Next-Generation 737. In addition, the company continues to study further potential 737 rate increases, given continued customer demand. “With over 5,200 sold to date, the Next-Generation 737 is the workhorse in our customers’ fleets around the world,” said Boeing Commercial Airplanes President and CEO Jim Albaugh. “Even through the global economic downturn, our diverse 737 backlog has remained very strong. Increasing the 737 production rate is the right thing to do to meet the growth and fleet replacement needs of our customers.” The current production rate on the 737 program is 31.5 airplanes per month. Suppliers for the 737 program are prepared to support the rate increase. The production rate decision is not expected to have a material impact on 2010 financial results. “The global economy continues to recover this year and we believe that airlines will return to profitability in 2011,” said Randy Tinseth, vice president of Marketing for Boeing Commercial Airplanes. “We believe that there will be an increased demand for airplanes – especially in the market served by the Next-Generation 737 – in 2012 and beyond.” With more than 2,000 unfilled orders from more than 80 customers around the world, the Next-Generation 737 is the newest and most technologically advanced airplane in its class. Airfinance Journal’s investors’ and operators’ poll consistently ranks the Next-Generation 737 as the most preferred airplane in its class due to its wide market base, superior efficiency and lowest operating costs.
12 Dec 2009 - 737 Production Rate to Remain Same
Good news coming this week from a top Boeing Executive on 737 production rates. Boeing is seeing no reason to change how many of the 737 jetliners they build a month. All year, there's been growing speculation and concern Boeing would reduce how many 737's they build because a drop would likely lead to layoffs at Spriit Aerosystems. "There is no change and let me repeat. There is no change in our assessment that we can hold the 737 at its current build rate of about 31 airplanes per month," Boeing CFO James Bell said. No change on 737 rates could be some of the best news Spirit Aerosystems employees have heard in a while. Spirit is Boeing's largest supplier. The single aisle 737 fuselage then by rail sends it to Renton, Washington for assembly. Bell spoke at a Bank of America Merril Lynch conference this week and answered skeptics who've been predicting a 737 rate cut. "Now while I know that some are skeptical about our ability to hold our single aisle rates, there are several factors that support our rationale around this rate assumption." Bell says Boeing was careful not to ramp up 737 rates too high during the up cycle. Instead, he says the company worked with customers to keep rates steady for a longer time. "We had over committments of delivery positions and a large backlog of over 2,000 737's." So he says Boeing has been able to absorb order deferrals and cancellations on the 737 without cutting production. Boeings had 215 deferrals through the third quarter this year, but says, since then, order deferrals are slowing down. Also, Bell says airlines are replacing older less fuel efficient planes with ones to save money. "And that's helped us to be able to maintain those single aisle rates." Spirit Spokeswoman Debbie Gann says this is good news but also says Spirit is still working to control costs because of other production cuts. Now if the 787 successfully flies next week and gets on track, there will be more to celebrate in the new year.
10 Feb 2008 - Boeing considering increased production rate of 737
Boeing may increase production of its popular 737 line of narrowbody airliners, if domestic carriers place orders soon for the planes.
In comments before Cowen & Co.'s Aerospace/Defense conference last week, Boeing Commercial Airplanes CEO Scott Carson said the planemaker has mulled over whether to increase production of Boeing's best-selling line of aircraft. "It feels like there might be enough solid demand to do it, but we're watching very carefully," he said, according to TheStreet.com.
In addition to the question of whether suppliers could keep up with increased production rates, there's also the matter of whether a number of domestic carriers will soon place orders to justify the increase. During a conference call with investors last month, Boeing CEO Jim McNerney said the planemaker has "been in extended discussions with a couple of the major carriers who have not participated in this order cycle. It wouldn't surprise me if a couple of deals with these folks came to fruition in '08."
Industry analysts think big Boeing orders from American and Delta may soon be forthcoming, as those carriers look to replace their fleets of McDonnell-Douglas MD80-family aircraft. American, for one, has said numerous times it wants to replace its aged MD-82s and -83s. The carrier is slowly replacing its 300-plane fleet of MD-80s with new 737-800s, from a previous order. The carrier is slated to receive 23 -800s through 2009.
This week, Carson (right) noted American's MD-80s "are not very efficient with this fuel price," and will need to be replaced sooner or later. If that order comes 'sooner,' it alone could be enough to support increased production.
Less certain are Delta's plans to replace its own MD-88s and -90s. Both types are somewhat newer than American's models, and have more-efficient turbofans. But airline spokesperson Betsy Talton says Delta has no plans for "a significant fleet replacement order anytime soon.
"The strategy is to improve the fleet we have," she added. "Acquisitions will be limited and strategic in nature."
There is a wild card, however -- a possible Delta merger with Northwest Airlines. If such a merger takes place, the combined carrier -- which many believe will be run by Delta -- may move quickly to replace Northwest's ancient DC-9 fleet. The DC-9s are paid for... but at such high fuel prices, the savings from using more efficient aircraft would likely offset the added cost of making lease payments.
If the decision to step up production comes, Boeing could make as many as 40 737s per month, up from its current level of 32 planes, according to industry analyst Scott Hamilton. "They've been looking at it for quite some time," he said. "The question has been whether the supply chain can do that."
Hamilton adds Carson criticized rival Airbus's plans in 2006 to ramp up production of the A320 narrowbody line. "In this hot market, it would be easy to be consumed with the desire to sell anything to people walking through the door who want to buy and push our production system to the point where you could break it," Carson said in September 2006, as reported by ANN. "It’s much harder to say, 'I’m sorry, we’re sold out.'"
Indeed, Boeing was hamstrung by that very problem in the late 1990s... and the resulting flood of Boeing planes in a cooling market, as it fought to compete with Airbus, almost bankrupted the planemaker.
There's also the question of whether Boeing's current five-year backlog on 737 production may be cut back drastically, as airlines seek to cancel orders due to slackening demand... which, depending on who you listen to, may or may not be coming.
27 Nov 2007 - 737 Flaps to be Built in Vietnam
TOKYO (AFP) — Japan's Mitsubishi Heavy Industries said Tuesday that it aimed to be the world's first manufacturer to open an aircraft-related production plant in Vietnam with a new facility due to open next year.
The production plant, which is due to open in Hanoi in January, will employ up to about 200 people when production picks up assembling flaps for the Boeing 737, a company statement said.
It said the move was in response to growing price competition, praising Vietnam's "diligent labour force, robust economy, stable public security and the presence of overseas transport routes."
Mitsubishi Heavy Industries said it would be "the first manufacturer in the world to locate its aircraft-related production facility in Vietnam."
The Japanese group is looking to shift some of its assembly operations overseas and focus its domestic facilities on high value-added work.
Mitsubishi also manufactures wings for Boeing's next-generation 7E7 Dreamliner jet and is developing what it hopes will be the first passenger jet to be built in Japan.
The announcement coincided with a visit to Japan by Vietnamese President Nguyen Minh Triet, whose country is enjoying rapid economic growth and luring a growing number of Japanese companies to set up production plants there.
Japan is a major market for Boeing, with Japanese carriers buying planes almost exclusively from the US aerospace giant.
28 Apr 2005 - Boeing Looks into Raising 737 Production
By Dan Roberts in New York
Boeing is examining ways to ramp up production of its short-to-medium range 737 aircraft as recent strong demand places strains on manufacturing capacity.
Some analysts believe there is now a 36-month wait for the US manufacturer's single-aisle jet, which has proved popular among budget airlines.
21 Apr 2005 - Boeing may cut back in Wichita
If Boeing Co. doesn't sell its Wichita commercial operation to Onex Corp., the airplane maker will likely reduce its presence there, a Boeing official said this week.
The Wichita site could be divided into fuselage work, strut and nacelle work and support work. The company also could outsource production of smaller parts and explore a sale of its fabrication business.
In short, Boeing would continue its overall strategy of focusing on large-scale systems integration, Morris said.
"We wouldn't be able to continue to invest the money into Wichita to allow it to grow," he said.
And Wichita likely would not receive major portions of future new airplane programs, including any replacement for Boeing's popular 737 or any new plane after the planned 787, Morris said. Boeing Wichita builds the 737 fuselage.
1 Apr 2005 - Asian Composites Manufacturing Selected to Produce Boeing 737 Aileron Components
The Boeing Company and Asian Composites Manufacturing Sdn Bhd (ACM) recently celebrated the selection of the Malaysian company to produce aileron panels and components for the Boeing Next-Generation 737 family of airplanes and the first delivery to Hawker de Havilland this month. During the ceremony, Michael Rufert, managing director, Hawker de Havilland, presented a plaque to Dr. Nazily Noor, general manager, ACM. Nazily, displaying a sample composite aileron panel, then provided information on the components, their importance to ACM's business and ACM's selection for this important work.
Asian Composites Manufacturing Sdn Bhd -- a strategic alliance between Sime Darby Berhad and Naluri Berhad of Malaysia and Boeing and Hexcel Corporation of the United States -- is a world leader in supplying composite materials to the global aerospace industry. Hawker de Havilland, a Boeing subsidiary, headquartered in Port Melbourne, Victoria, Australia, is the integrator for 737 ailerons.
Ailerons are hinged sections on the trailing edge of each wing that are used to help the airplane to bank, allowing the airplane's flight path to curve.. Ailerons typically work in opposition to each other -- the right aileron is deflected in the opposite direction that the left is deflected.
The aileron components are shipped to Hawker de Havilland for incorporation into complete aileron units. Final assembly for the Boeing 737 family is based in Renton , Wash.
"We are delighted to be entrusted with the manufacture of these Boeing Next- Generation 737 aileron components and we look forward to providing the world's airlines with the high quality and reliability that they associate with the 737 family," said Dr. Nazily. "Because of the rapid growth of the global commercial airplane market and the extreme popularity of the 737, this new work will increase our production by about 15 percent."
ACM currently produces advanced composite structures for wings of all Boeing jetliners in production. The ACM facility, located in Bukit Kayu Hitam, commenced production in June 2001 and employs more than 310 skilled Malaysians, along with an all-Malaysian management team.
"The selection of ACM is evidence that the management and production teams have proven their dedication and commitment to excellence," said Dr. Dinesh Keskar, senior vice president, Sales -- Boeing Commercial Airplanes. "This is an excellent example of a growing partnership between Boeing and the Malaysian aviation industry."
2 Mar 2005 - Alcoa has agreed to a multi-year contract with Shanghai Aircraft Manufacturing Factory to provide aluminum parts for the tail section assembly of the Boeing 737, the companies announced Monday.
Alcoa's China Alcoa Global Extruded and End Products business will produce 650,000 pounds of hard alloy aluminum extrusions a year at plants in Lafayette, Ind., and South Korea starting immediately. Alcoa already supplies aluminum sheet and plate and aerospace fasteners to Shanghai Aircraft Manufacturing.
When this first 737-900 enters service with launch customer Alaska Airlines early next year, it will haul up to 177 passengers in a two-class configuration, with the range to go from coast to coast.
"We expect the 737-900 to be very successful," said Steve Ford, Boeing's regional director of product marketing. "When operators begin to see the efficiency this plane brings, the economics will be very compelling."
Boeing has so far landed 45 firm orders for its newest 737, including 10 from Alaska, 15 from Continental, four from KLM and 16 from Korean Air.
The 737-900 is scheduled to roll out of the Renton plant in late July, with first flight near the end of August. After a six-month flight-test program and certification, it should be ready for delivery to Alaska next April.
Begun in November 1997 with the order from Alaska, the 737-900 joins three other smaller siblings in the next-generation family -- the -600, -700 and -800 series.
This is the last offspring, Boeing says.
"We are not expecting any larger family members, and no smaller family members, either," Ford said.
The 737-900 is a stretched version of the 737-800. Boeing added a forward body plug of 62 inches and an aft plug of 42 inches, which increased the overall length by 8 feet 8 inches.
In a two-class configuration, the additional length allows the 737-900 to carry about 15 more passengers than the 737-800. But the increased size and weight mean slightly less range. The 737-900 can fly 2,745 nautical miles, about 200 miles less than the 737-800.
The 737-700 can fly the farthest of the four models -- 3,260 nautical miles.
The maximum seating capacity of the 737-900 is 189, a limit imposed by federal regulation based on the number of exit doors and how quickly passengers can get out in an emergency.
All four next-generation models have the same wingspan.
The -600 series is the shortest of the four, at 102 feet 6 inches. It carries about 110 passengers in a two-class configuration. The 737-900 is 138 feet 2 inches in length.
The 737-900 fuselage, which includes everything but the tail section and the nose radome, is 124 feet 4 inches long. That's 4 feet longer than the Wright brothers' first flight.
It is so long that a secondary railroad track must be used during the short trip through Seattle's downtown railroad tunnel. Boeing discovered last year when it sent a mockup of the 737-900 fuselage on a test run by rail from Wichita to Renton that because of the angle, the fuselage hit the tunnel walls when track No. 1 was used.
That was the only transportation problem encountered on the 2,019-mile journey from Wichita, though Boeing found it had to cut back a wall at its Renton plant by 2 feet where the fuselage is unloaded from the rail car.
The first of the next-generation jets, which can fly higher, farther and with much greater operating economics than the older model 737s, was the 737-700. It rolled out of the Renton factory in December 1996.
Through the end of March, Boeing had firm orders for 1,404 of the next-generation jets, not including the Boeing Business Jet, which is a version of the 737-700. Of those ordered, 451 have been delivered to airlines.
The next-generation 737s compete with the Airbus A320 family, which has proved a formidable rival. The A320 family consists of the A319, a shrunken version of the mother plane, and the A321, which is a stretch.
Airbus has won several significant competitions the past couple of years in which its A320 went head to head with the next-generation 737.
But the Boeing planes are selling fairly well, especially the 737-800, which has 655 orders, and the 737-700, with 600 orders. The 737-600 has so far done poorly in the market, with only 104 orders.
Airbus claims its single-aisle plane is technologically superior, because Boeing based the next generation on a design that is almost 40 years old.
The first 737-100 was built in the mid-1960s. Boeing counters that the next-generation 737 is more advanced than the A320, which entered service in the 1980s.
Richard Aboulafia, senior aerospace analyst at the Teal Group, said the next-generation 737 is a very good airplane.
"I say it's good enough and more successful than generally appreciated," he said. That's especially true of the 737-700 and 737-800, he said, noting that American Airlines recently decided to buy the 737-800, the first time American has chosen Boeing's 737.
He thinks the 737-900 will do well, too.
"That's the ultimate air transport as a commodity," he said. "A large number of people in a jet with few bathrooms. It can't be pleasant, but it sure will be cheap."
Because of the good operating economics, airlines are using their new 737-700s and 737-800s on longer, non-stop routes, including coast to coast. Aloha Airlines, for example, recently began 737-700 service between the Hawaiian Islands and Oakland, Calif.
Some passengers do not like to fly the new 737s on such long routes, arguing it is too uncomfortable for a four- to five-hour flight.
"Is it comfortable? Not really," Aboulafia said. "But comfort is not really an issue on domestic flights. Air transport, domestically, is a commodity. It is no different than taking the train or the bus. It's not something you do to enjoy the food or play billiards. You want to go from point A to point B as cheaply as possible."
Although Boeing plans no more entries in its next-generation family, the company is expected to develop the 737-700X, which would be a superlong-range version that could fly more than 4,000 nautical miles. Boeing sees a possible niche market for the jet on routes between Europe and the East Coast.
