Boeing 767

Boeing 767

The Boeing 767 is an American wide-body aircraft developed and manufactured by Boeing Commercial Airplanes. The aircraft was launched as the 7X7 program on July 14, 1978, the prototype first flew on September 26, 1981. The original 767-200 entered service on September 8, 1982. To complement the larger 747, it has a seven-abreast cross-section. The 767 is Boeing's first wide-body twinjet, powered by General Electric CF6, Rolls-Royce RB211, or Pratt & Whitney JT9D turbofans. JT9D engines were eventually replaced by PW4000 engines. The aircraft has a conventional tail and a supercritical wing for reduced aerodynamic drag. Its two-crew glass cockpit, a first for a Boeing airliner, was developed jointly for the 757, allowing a common pilot type rating. Studies for a higher-capacity 767 in 1986 led Boeing to develop the larger 777 twinjet, introduced in June 1995. A total of 742 of 767 aircraft were in service in July 2018, with Delta Air Lines being the largest operator with 77 aircraft in its fleet. As of December 2022, Boeing has received 1,373 orders from 74 customers, of which 1,271 airplanes have been delivered, while the remaining orders are for cargo or tanker variants.Its successor, the 787 Dreamliner, entered service in 2011.

Variants
767-200
The 767-200 was the original model and entered service in 1982. Deliveries for the variant totaled 128 aircraft. There were 52 examples of the model in commercial service as of July 2018, almost entirely as freighter conversions. 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. 
767-2C
767-2C A commercial freighter version of the Boeing 767-200 with wings from the -300 series and an updated flightdeck was first flown on 29 December 2014. 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. As of 2014, Boeing does not have customers for the freighter.  
767-200ER
The -200ER is externally similar to the -200. The 767-200ER was the first extended-range model and entered service in 1984. The type's increased range is due to extra fuel capacity and higher maximum takeoff weight. 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. The center tank is also used on the -300ER and -400ER variants. This version was originally offered with the same engines as the 767-200, while more powerful Pratt & Whitney PW4000 and General Electric CF6 engines later became available. The 767-200ER was the first 767 to complete a non-stop transatlantic journey, and broke the flying distance record for a twinjet airliner on April 17, 1988 covering 8,727 nmi (16,200 km; 10,000 mi). Deliveries of the type totaled 121 with no unfilled orders. As of July 2018, 21 examples of passenger and freighter conversion versions were in airline service.   



767-300  
The 767-300, the first stretched version of the aircraft, entered service in 1986. The type features a 21.1-foot (6.43 m) fuselage extension over the 767-200, achieved by additional sections inserted before and after the wings, for an overall length of 180.25 ft (54.9 m). While more powerful Pratt & Whitney PW4000 and Rolls-Royce RB211 engines later became available. 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.
767-300ER
The 767-300ER, the extended-range version of the 767-300, entered service with American Airlines in 1988. The type's increased range was made possible by greater fuel tankage. Power is provided by Pratt & Whitney PW4000, General Electric CF6, or Rolls-Royce RB211 engines. It is the most successful 767 version, with more orders placed than all other variants combined. As of November 2017, 767-300ER deliveries stand at 583 with no unfilled orders. There were 376 examples in service as of July 2018. At its 1990s peak, a new 767-300ER was valued at $85 million, dipping to around $12 million in 2018 for a 1996 build.  
767-300F
The 767-300F, the production freighter version of the 767-300ER, entered service in 1995. The 767-300F can hold up to 24 standard 88-by-125-inch (220 by 320 cm) pallets on its main deck and up to 30 LD2 unit load devices on the lower deck, with a total cargo volume of 15,469 cubic feet (438 m3). A general market version with onboard freight-handling systems, refrigeration capability, and crew facilities was delivered to Asiana Airlines on August 23, 1996. As of August 2019, 767-300F deliveries stand at 161 with 61 unfilled orders. Airlines operated 222 examples of the freighter variant and freighter conversions in July 2018. 
767-300BCF
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. Since then, Boeing, Israel Aerospace Industries, and Wagner Aeronautical have also offered passenger-to-freighter conversion programs for 767-300 series aircraft.



767-400ER
The 767-400ER, the first Boeing wide-body jet resulting from two fuselage stretches, entered service in 2000. The type features a 21.1-foot (6.43-metre) stretch over the 767-300, for a total length of 201.25 feet (61.3 m). The wingspan is also increased by 14.3 feet (4.36 m) through the addition of raked wingtips. Differences include an updated cockpit, redesigned landing gear. Power is provided by uprated General Electric CF6 engines. Because its fuel capacity was not increased over preceding models, the 767-400ER has a range of 5,625 nautical miles (10,418 km), less than previous extended-range 767s. No 767-400 (non-extended range) version was developed. Boeing dropped the 767-400ER and the -200ER from its pricing list in 2014. A total of 37 767-400ERs were delivered to the variant's two airline customers, with no unfilled orders. All 37 examples of the -400ER were in service in July 2018.
