Based on the standard Boeing 767-200, the Boeing 767-200ER with an increased flight range was created, and then even more capacious versions of the Boeing 767-300 and Boeing 767-300ER. The capabilities of the 767th family have grown even more with the advent of the Boeing 767-400.
The Boeing 767 was the first twin-engine wide-body airliner created by Boeing and one of the first aircraft to be certified according to ETOPS standards (Extended-range Twin-engined OPerationS – the norms of the ICAO international organization for flying on a twin-engine aircraft in low-oriented areas). When the Boeing 767-200 went into operation with United Airlines in September 1982, it immediately faced stiff competition from the A300 and A310, especially the long-haul A300-600R and A310-300. In response, Boeing developed a longer-range Boeing 767-200ER, and in February 1983 announced the development of a larger Boeing 767-300, with plans to begin shipping in early 1986. The first firm order came in September 1983 from JAL.
The first Boeing 767-300 took off on January 30, 1986, the type certificate was received in September. The first airliner was delivered to the customer, the Japanese company JAL, on September 25th. The new variant received a fuselage elongated by 6.42 m – one insert was made in front of and behind the wing. The remaining dimensions remained the same, except the cabin extended to 40.39 m. In the two-class layout, the Boeing 767-300 was designed for 261 seats (20% more than in the 200th), and in the three-class layout – for 210 seats. Since 1989, the Boeing 767-300 has been certified to carry a maximum of 360 passengers. For example, Britannia Airways operates a Boeing 767-300 with a capacity of 328 seats.
The maximum take-off weight of the Boeing 767-300 is 158760 kg, and the flight range with 261 passengers is 7680 km. Initially, the aircraft was offered in versions with General Electric CF6-80A2 or Pratt & Whitney JT9D-7R4D engines with a thrust of 222.5 kN, but other power plant options were developed during operation: with PW4000 family engines with a thrust of 252-267 kN, as well as with Rolls Royce RB211-524H engines with a thrust of 270 kN. Start-up customer JAL chose CF6 engines, and Delta Air Lines ordered JT9D as the first option.
