Development


Background

In 1970, the 747 entered service as the first wide-body jetliner with a fuselage wide enough to feature a twin-aisle cabin. Two years later, the manufacturer began a development study, code-named 7X7, for a new wide-body jetliner intended to replace the

wide-bodies. To defray the high cost of development, Boeing signed risk-sharing agreements with Italian corporation Aeritalia and the Civil Transport Development Corporation (CTDC), a consortium of Japanese aerospace companies. This marked the manufacturer's first major international joint venture, and both Aeritalia and the CTDC received supply contracts in return for their early participation. The initial 7X7 was conceived as a short take-off and landing airliner intended for short-distance flights, but customers were unenthusiastic about the concept, leading to its redefinition as a mid-size, transcontinental-range airliner. At this stage the proposed aircraft featured two or three engines, with possible configurations including over-wing engines and a

. By 1976, a twinjet layout, similar to the one which had debuted on the Airbus A300, became the baseline configuration. The decision to use two engines reflected increased industry confidence in the reliability and economics of new-generation jet powerplants. While airline requirements for new wide-body aircraft remained ambiguous, the 7X7 was generally focused on mid-size, high-density markets. As such, it was intended to transport large numbers of passengers between major cities. Advancements in civil aerospace technology, including high-bypass-ratio turbofan engines, new flight deck systems, aerodynamic improvements, and more efficient lightweight designs were to be applied to the 7X7. Many of these features were also included in a parallel development effort for a new mid-size narrow-body airliner, code-named 7N7, which would become the 757. Work on both proposals proceeded through the airline industry upturn in the late 1970s. In January 1978, Boeing announced a major extension of its Everett factory—which was then dedicated to manufacturing the 747—to accommodate its new wide-body family. In February 1978, the new jetliner received the 767 model designation, and three variants were planned: a with 190 seats, a with 210 seats, and a

and Delta Air Lines later that year. The 767-100 was ultimately not offered for sale, as its capacity was too close to the 757's seating, while the 777 trijet was eventually dropped in favor of standardizing the twinjet configuration.


Design effort

In the late 1970s, operating cost replaced capacity as the primary factor in airliner purchases. As a result, the 767's design process emphasized

The larger wings were designed using an aft-loaded shape which reduced aerodynamic drag and distributed lift more evenly across their surface span than any of the manufacturer's previous aircraft. The wings provided higher-altitude

The initial 767-200 was designed for sufficient range to fly across North America or across the northern Atlantic, and would be capable of operating routes up to . The 767's fuselage width was set midway between that of the 707 and the 747 at . While it was narrower than previous wide-body designs, seven abreast seating with two aisles could be fitted, and the reduced width produced less aerodynamic drag. The fuselage was not wide enough to accommodate two standard LD3 wide-body unit load devices side-by-side, so a smaller container, the LD2, was created specifically for the 767. Using a conventional tail design also allowed the rear fuselage to be tapered over a shorter section, providing for parallel aisles along the full length of the passenger cabin, and eliminating irregular seat rows toward the rear of the aircraft. The 767 was the first Boeing wide-body to be designed with a two-crew digital glass cockpit.

Despite the promise of reduced crew costs, United Airlines initially demanded a conventional three-person cockpit, citing concerns about the risks associated with introducing a new aircraft. The carrier maintained this position until July 1981, when a US presidential task force determined that a crew of two was safe for operating wide-body jets. A three-crew cockpit remained as an option and was fitted to the first production models.

Production and testing

To produce the 767, Boeing formed a network of subcontractors which included domestic suppliers and international contributions from Italy's Aeritalia and Japan's CTDC. The wings and cabin floor were produced in-house, while Aeritalia provided control surfaces,

Entry into service

The 767 entered service with United Airlines on September 8, 1982. The aircraft's first commercial flight used a JT9D-powered on the Chicago-to-Denver route. The CF6-powered 767-200 commenced service three months later with Delta Air Lines. Upon delivery, early 767s were mainly deployed on domestic routes, including US transcontinental services. American Airlines and TWA began flying the 767-200 in late 1982, while Air Canada, China Airlines, El Al, and Pacific Western began operating the aircraft in 1983. The aircraft's introduction was relatively smooth, with few operational glitches and greater dispatch reliability than prior jetliners.


Stretched derivatives

Forecasting airline interest in larger-capacity models, Boeing announced the stretched in 1983 and the extended-range 767-300ER in 1984. Both models offered a 20 percent passenger capacity increase, while the extended-range version was capable of operating flights up to . Japan Airlines placed the first order for the -300 in September 1983. Following its first flight on January 30, 1986, the type entered service with Japan Airlines on October 20, 1986. The 767-300ER completed its first flight on December 9, 1986, but it was not until March 1987 that the first firm order, from American Airlines, was placed. The type entered service with American Airlines on March 3, 1988. The 767-300 and 767-300ER gained popularity after entering service, and came to account for approximately two-thirds of all 767s sold. After the debut of the first stretched 767s, Boeing sought to address airline requests for greater capacity by proposing larger models, including a partial double-deck version informally named the "Hunchback of Mukilteo" (from a town near Boeing's Everett factory) with a 757 body section mounted over the aft main fuselage. In 1986, Boeing proposed the 767-X, a revised model with extended wings and a wider cabin, but received little interest. By 1988, the 767-X had evolved into an all-new twinjet, which revived the

designation. Until the 777's 1995 debut, the 767-300 and 767-300ER remained Boeing's second-largest wide-bodies behind the 747. Buoyed by a recovering global economy and ETOPS approval, 767 sales accelerated in the mid-to-late 1980s; 1989 was the most prolific year with 132 firm orders. By the early 1990s, the wide-body twinjet had become its manufacturer's annual best-selling aircraft, despite a slight decrease due to economic recession. During this period, the 767 became the most common airliner for transatlantic flights between North America and Europe. By the end of the decade, 767s crossed the Atlantic more frequently than all other aircraft types combined. The 767 also propelled the growth of point-to-point flights which bypassed major

s in favor of direct routes. Taking advantage of the aircraft's lower operating costs and smaller capacity, operators added non-stop flights to secondary population centers, thereby eliminating the need for connecting flights. The increased number of cities receiving non-stop services caused a paradigm shift in the airline industry as point-to-point travel gained prominence at the expense of the traditional hub-and-spoke model.

. Six months later, the carrier temporarily grounded its entire 767 fleet after discovering cracks in the engine pylons of several aircraft. The cracks were related to the extra weight of the RB211 engines, which are heavier than other 767 engines. During the grounding, interim repairs were conducted to alleviate stress on engine pylon components, and a parts redesign in 1991 prevented further cracks. Boeing also performed a structural reassessment, resulting in production changes and modifications to the engine pylons of all 767s in service. In January 1993, following an order from UPS Airlines, Boeing launched a freighter variant, the 767-300F, which entered service with UPS on October 16, 1995. The 767-300F featured a main deck cargo hold, upgraded landing gear, and strengthened wing structure.

. In November 1995, after abandoning development of a smaller version of the 777, Boeing announced that it was revisiting studies for a larger 767. The proposed 767-400X, a second stretch of the aircraft, offered a 12 percent capacity increase versus the , and featured an upgraded flight deck, enhanced interior, and greater wingspan. The variant was specifically aimed at Delta Air Lines' pending replacement of its aging Lockheed L-1011 TriStars, and faced competition from the A330-200, a shortened derivative of the Airbus A330. In March 1997, Delta Air Lines launched the 767-400ER when it ordered the type to replace its L-1011 fleet. In October 1997,

Dreamliner introduction

In the early 2000s, cumulative 767 deliveries approached 900, but new sales declined during an airline industry downturn. In 2001, Boeing dropped plans for a longer-range model, the 767-400ERX, in favor of the proposed Sonic Cruiser, a new jetliner which aimed to fly 15 percent faster while having comparable fuel costs to the 767. The following year, Boeing announced the KC-767 Tanker Transport, a second military derivative of the 767-200ER. Launched with an order in October 2002 from the

s which promised to be 20 percent more fuel efficient. The new jetliner was the first stage of a replacement aircraft initiative called the Boeing Yellowstone Project. Customers embraced the 7E7, later renamed 787 Dreamliner, and within two years it had become the fastest-selling airliner in the company's history. In 2005, Boeing opted to continue 767 production despite record Dreamliner sales, citing a need to provide customers waiting for the 787 with a more readily available option. Subsequently, the 767-300ER was offered to customers affected by 787 delays, including All Nippon Airways and Japan Airlines. Some aging 767s, exceeding 20 years in age, were also kept in service past planned retirement dates due to the delays. To extend the operational lives of older aircraft, airlines increased heavy maintenance procedures, including D-check teardowns and inspections for

placed a combined 33 orders for the 767-300F. Renewed freighter interest led Boeing to consider enhanced versions of the 767-200 and 767-300F with increased gross weights, 767-400ER wing extensions, and 777 avionics. Net orders for the 767 declined from 24 in 2008 to just three in 2010. During the same period, operators upgraded aircraft already in service; in 2008, the first 767-300ER retrofitted with blended

Other carriers including All Nippon Airways and Delta Air Lines also ordered winglet kits. On February 2, 2011, the 1,000th 767 rolled out, destined for All Nippon Airways. The aircraft was the 91st 767-300ER ordered by the Japanese carrier, and with its completion the 767 became the second wide-body airliner to reach the thousand-unit milestone after the 747. The 1,000th aircraft also marked the last model produced on the original 767 assembly line. Beginning with the 1,001st aircraft, production moved to another area in the Everett factory which occupied about half of the previous floor space. The new assembly line made room for 787 production and aimed to boost manufacturing efficiency by over twenty percent. At the inauguration of its new assembly line, the 767's order backlog numbered approximately 50, only enough for production to last until 2013. Despite the reduced backlog, Boeing officials expressed optimism that additional orders would be forthcoming. On February 24, 2011, the USAF announced its selection of the KC-767 Advanced Tanker, an upgraded variant of the KC-767, for its KC-X fleet renewal program.

In December 2011, FedEx Express announced a 767-300F order for 27 aircraft to replace its DC-10 freighters, citing the USAF tanker order and Boeing's decision to continue production as contributing factors. FedEx Express agreed to buy 19 more of the −300F variant in June 2012. In June 2015, FedEx said it was accelerating retirements of planes both to reflect demand and to modernize its fleet, recording charges of $276 million. On July 21, 2015, FedEx announced an order for 50 767-300F with options on another 50, the largest order for the type. With the announcement FedEx confirmed that it has firm orders for 106 of the freighters for delivery between 2018 and 2023.

In 2019, unit cost was US$217.9 million for a -300ER, and US$220.3 million for a -300F.


Re-engined 767-XF

In October 2019, Boeing was reportedly studying a re-engined 767-XF for entry into service around 2025, based on the 767-400ER with an extended landing gear to accommodate larger General Electric GEnx turbofan engines. The cargo market is the main target, but a passenger version could be a cheaper alternative to the proposed New Midsize Airplane.

. The standard seven abreast, 2–3–2 economy class layout places approximately 87 percent of all seats at a window or aisle. As a result, the aircraft can be largely occupied before center seats need to be filled, and each passenger is no more than one seat from the aisle. It is possible to configure the aircraft with extra seats for up to an eight abreast configuration, but this is less common. The 767 interior introduced larger overhead bins and more lavatories per passenger than previous aircraft. The bins are wider to accommodate

Subsequently, adopted for all new-build 767s, the Signature Interior features even larger overhead bins, indirect lighting, and sculpted, curved panels. The 767-400ER also received larger windows derived from the 777. Older 767s can be retrofitted with the Signature Interior. Some operators have adopted a simpler modification known as the Enhanced Interior, featuring curved ceiling panels and indirect lighting with minimal modification of cabin architecture, as well as aftermarket modifications such as the NuLook 767 package by Heath Tecna.


Operational history

In its first year, the 767 logged a 96.1 percent dispatch rate, which exceeded the industry average for all-new aircraft. Operators reported generally favorable ratings for the twinjet's sound levels, interior comfort, and economic performance. Resolved issues were minor and included the recalibration of a leading edge sensor to prevent false readings, the replacement of an

) regulations, the FAA's safety rules governing transoceanic flights by aircraft with two engines. Before the 767, overwater flight paths of twinjets could be no more than 90 minutes away from diversion airports. In May 1985, the FAA granted its first approval for 120-minute ETOPS flights to 767 operators, on an individual airline basis starting with TWA, provided that the operator met flight safety criteria. This allowed the aircraft to fly overseas routes at up to two hours' distance from land. The larger safety margins were permitted because of the improved reliability demonstrated by the twinjet and its turbofan engines. The FAA lengthened the ETOPS time to 180 minutes for CF6-powered 767s in 1989, making the type the first to be certified under the longer duration, and all available engines received approval by 1993. Regulatory approval spurred the expansion of transoceanic 767 flights and boosted the aircraft's sales.


Variants

The 767 has been produced in three fuselage lengths. These debuted in progressively larger form as the , , and 767-400ER. Longer-range variants include the 767-200ER and 767-300ER, while cargo models include the 767-300F, a production freighter, and conversions of passenger 767-200 and 767-300 models. When referring to different variants, Boeing and airlines often collapse the model number (767) and the variant designator, e.g. –200 or –300, into a truncated form, e.g. "762" or "763". Subsequent to the capacity number, designations may append the range identifier, though -200ER and -300ER are company marketing designations and not certificated as such. The

flights, beginning with TWA on February 1, 1985, under 90-minute diversion rules. Deliveries for the variant totaled 128 aircraft. There were 52 examples of the model in commercial service , almost entirely as freighter conversions. The type's competitors included the Airbus A300 and A310. The 767-200 was produced until 1987 when production switched to the extended-range 767-200ER. Some early 767-200s were subsequently upgraded to extended-range specification. In 1998, Boeing began offering 767-200 conversions to 767-200SF (Special Freighter) specification for cargo use, and Israel Aerospace Industries has been licensed to perform cargo conversions since 2005. The conversion process entails the installation of a side cargo door, strengthened main deck floor, and added freight monitoring and safety equipment. The 767-200SF was positioned as a replacement for Douglas DC-8 freighters.


767-2C

A commercial freighter version of the Boeing with wings from the -300 series and an updated flightdeck was first flown on 29 December 2014. A military tanker variant of the Boeing 767-2C is being developed for the USAF as the KC-46. Boeing is building two aircraft as commercial freighters which will be used to obtain Federal Aviation Administration certification, a further two Boeing 767-2Cs will be modified as military tankers. , Boeing does not have customers for the freighter.


767-200ER

The 767-200ER was the first extended-range model and entered service with El Al in 1984. The type's increased range is due to extra fuel capacity and higher maximum takeoff weight (MTOW) of up to . The additional fuel capacity is accomplished by using the center tank's dry dock to carry fuel. The non-ER variant's center tank is what is called ''cheek tanks''; two interconnected halves in each wing root with a dry dock in between. The center tank is also used on the -300ER and -400ER variants. This version was originally offered with the same engines as the , while more powerful Pratt & Whitney PW4000 and

The 767-300's increased capacity has been used on high-density routes within Asia and Europe. The 767-300 was produced from 1986 until 2000. Deliveries for the type totaled 104 aircraft with no unfilled orders remaining. As of July 2018, 34 of the variant were in airline service. The type's main competitor was the Airbus A300.


767-300ER

The 767-300ER, the extended-range version of the , entered service with American Airlines in 1988. The type's increased range was made possible by greater fuel tankage and a higher MTOW of . Design improvements allowed the available MTOW to increase to by 1993. Power is provided by Pratt & Whitney PW4000, General Electric CF6, or Rolls-Royce RB211 engines. the 767-300ER comes in three exit configurations: the baseline configuration has four main cabin doors and four over-wing window exits, the second configuration has six main cabin doors and two over-wing window exits; and the third configuration has six main cabin doors, as well as two smaller doors that are located behind the wings.

Airlines operated 222 examples of the freighter variant and freighter conversions in July 2018. In June 2008, All Nippon Airways took delivery of the first 767-300BCF (Boeing Converted Freighter), a modified passenger-to-freighter model. The conversion work was performed in Singapore by ST Aerospace Services, the first supplier to offer a 767-300BCF program, and involved the addition of a main deck cargo door, strengthened main deck floor, and additional freight monitoring and safety equipment. Since then, Boeing, Israel Aerospace Industries, and Wagner Aeronautical have also offered passenger-to-freighter conversion programs for series aircraft.

Undeveloped variants


767-X

In 1986, Boeing announced plans for a partial double-deck Boeing 767 design. The aircraft would have combined the Boeing with a Boeing 757 cross section mounted over the rear fuselage. The Boeing 767-X would have also featured extended wings and a wider cabin. The 767-X did not get enough interest from airlines to launch and the model was shelved in 1988 in favor of the Boeing 777.
