Fokker F100 and F70 aircraft have become successful heirs to the popular F28 series airliners. However, their Dutch manufacturing company could not reduce production costs, which ultimately led to its bankruptcy. So ended the story of Fokker aircraft.
In the late 1970s, Fokker was developing a new project to replace the F28 Fellowship. The obvious first step was to lengthen the 100-seat aircraft to the size of the 130-seat Super F28 airliner. It was planned to offer such an aircraft to customers by 1984. In those days, there were no small jets on West European airlines, and Fokker decided to launch large aircraft on the market. The Super F28 project became the F29 150-seat airliner, although the design of this aircraft was still unclear. At some point, Fokker intended to use the Boeing 737 fuselage sections. Then it joined forces with McDonnell Douglas in the MDF 100 project, but this project was covered in the late 1980s. The company had only one thing – to return to its proven project F28.
In November 1983, Fokker announced that it was developing a 100-seat version of the F28. This aircraft was launched as the Fokker 100 (F100) project along with the Fokker 50 turboprop aircraft (a modified version of the F27 Friendship). Deliveries of F100 worth $ 14.9 million could begin in 1987. Fokker predicted the market for 750 such aircraft.
The new aircraft used the F28 fuselage, extended by 5.51 m, which now could accommodate 107 passengers. The F100 also received a new elongated wing, modified cockpit glazing, and Rolls-Royce Tau turbofan engines. The early versions were equipped with Tau 650-15 engines with a power of 61.60 kN, but later they have replaced with Tau 650-15 engines with a power of 67.19 kN.
For the manufacture of components “Fokker” began to cooperate with other European companies. Daimler Aerospace Airbus from Germany assembled the middle and rear sections of the fuselage, Short Brothers from Northern Ireland supplied the wing, and Dowty made the nose landing gear. The Northrop Grumman company ordered composite engine nacelles and traction reversers, while the Menasco company ordered the main landing gear.
The first buyer of the new airliner in July 1984 was Swissair, which ordered eight aircraft to replace the DC-9. Then Fokker waited patiently for almost a year for orders from other airlines. Finally, in May 1985, KLM ordered 10 aircraft. The release of the version with more powerful engines was launched in August 1985 after receiving an important order from American Airlines. The Americans initially ordered only 10 aircraft, but later increased the order to 75 aircraft.
According to customer requirements, Fokker has made several changes to serial airliners. The aircraft was equipped with Collins EFIS cabins with six glazing panels and a Honeywell flight control system, and the operational weight of the aircraft was increased. The need to simultaneously build prototypes of aircraft of two completely new projects caused a delay in the launch of the F100 for testing. He first took off only on November 30, 1986, and the certification was postponed until the fall of 1987.
The second prototype F100 took off on February 25, 1987. The aircraft passed the 1,100-hour flight test program and was certified by the Dutch authorities on November 27. Swissair Airlines received its first production aircraft on February 9, 1988. On April 3, he began flying on the Zurich-Vienna line. The first F100 with boosted engines took off on July 8th. With its appearance in February 1989, an order was received for 75 aircraft from American Airlines. The more power-armed F100 was certified on May 30, 1989. On July 1, the first aircraft was received by USAir (later renamed to US Airways), which decided to purchase 40 F100.
