The decision to create an option with an increased flight range of the Boeing 767-300ER was made in 1984. The first plane took off on November 9, 1986, but Boeing received its first orders for the car only in March 1987 – American Airlines ordered 15 aircraft. In mid-1987, a version with General Electric engines was certified, and in the spring of 1988, with Pratt-Whitney engines. Aircraft deliveries began in February 1988.
The liner had an increased fuel supply and maximum take-off weight. During the first demonstration of the new version in 1986, the maximum take-off mass was 172368 kg, subsequently, it increased to 184615 kg, and by 1993 to 186883 kg. Powertrain options included CF6-80C2B2 and PW4000 engines. The Austrian Lauda Air became the start customer for the Pratt 8c Whitney engine (April 1987), and British Airways was the first to purchase the more powerful Rolls-Royce RB211-524G / H (certified in December 1989). A total of seven airlines chose the 300th, and another 36 ordered the Boeing 767-300ER variant. By July 1, 1999, there were 107 orders for the 767-300 (100 deliveries were completed), and for the 767-300ER there were 440 and 395, respectively.
The aircraft uses the digital avionics complex EFIS manufactured by the American company Rockwell-Collins, which has six color multifunction displays. A similar complex is used on Boeing 757 aircraft.
The longer-range variant of the Boeing 767-300ER became the most demanded in the Boeing 767 family. As of October 1, 1999, 36 companies placed orders for 440 aircraft of this type. The largest operators of the Boeing 767-300ER are the American Delta (57), American Airlines (58) and United (37), but other companies actively bought the plane: Ansett (24; now the company does not exist), British Airways (28; top), Canadian (14), QANTAS (21), Scandinavian Airline System (14) and VARIG Airlines (10). Aircraft were also delivered to smaller airlines, but several air carriers such as Air New Zealand and Eva Air (on the left) opted for the Boeing 767-300ER as a more economical alternative to Boeing 777 / A340 class airliners.
