Design and development
Announced by Fokker in April 1962, production was a collaboration between a number of European companies, namely Fokker, MBB of West Germany, Fokker-VFW (also of Germany), and Short Brothers of Northern Ireland. There was also government money invested in the project, with the Dutch government providing 50% of Fokker's stake and the West German government having 60% of the 35% German stake.
Projected at first to transport 50 passengers to 1,650 km (1,025 mi), the plane was later designed to have 60–65 seats. On the design sheet, the F28 was originally to mount Bristol Siddeley BS.75 turbofans, but the prototype flew with the lighter Rolls-Royce "Spey Junior", a simplified version of the Rolls-Royce Spey.
The F28 was similar in design to the British Aircraft Corporation BAC One-Eleven and Douglas DC-9, as it had a T-tail and engines mounted at the rear of the fuselage. The aircraft had wings with a slight crescent angle of sweep with ailerons at the tip, simple flaps, and five-section liftdumper only operated after landing to dump the lift. These were employed rather than reverse thrust as the designers felt that doing so not only reduced weight, but maintenance also. Having no reversers also meant that on unpaved airstrips there was less chance of the engines ingesting debris. The leading edge was fixed (although one experimental model had leading edge slats and these were offered as an option) and was anti-iced by bleed air from the engines. The tail cone could split and be hydraulically opened to the sides to act as a variable air brake – also used on the contemporaneous Blackburn Buccaneer. This design was also used on the HS-146, which became the BAe-146. The design is unique in that it not only slows the aircraft down rapidly, it can aid in rapid descents from economic cruising altitudes and also allowed the engines to be set at higher RPM which helped eliminate 'lag time'. This means the engines respond faster if needed for sudden speed increases or go-arounds on the approach to landing. The Fellowship had a retractable tricycle landing gear which used large low pressure tyres enabling the use of unpaved airstrips. Large wheel brakes also helped in shortening the landing run.
In terms of responsibility for production, Fokker designed and built the nose section, centre fuselage and inner wing; MBB/Fokker-VFW constructed the forward fuselage, rear fuselage and tail assembly; and Shorts designed and built the outer wings.
The F28-1000 prototype, registered PH-JHG, first flew on 9 May 1967, flown by Chief Test Pilot Jas Moll, Test Pilot Abe van der Schraaf and Flight Engineer Cees Dik. German certification was achieved on 24 February 1969. The first order was from German airline LTU, but the first revenue-earning flight was by Braathens (who operated five F28s) on 28 March 1969.
The F28 with an extended fuselage was named F28-2000 and could seat up to 79 passengers instead of the 65 seats on the F28-1000. The prototype for this model was a converted F28-1000 prototype, and first flew on 28 April 1971. The models F28-6000 and F28-5000 were modified F28-2000 and F28-1000 respectively, with slats, greater wingspan, and more powerful and quieter engines as the main features. The F28-6000 and F28-5000 were not a commercial success; only two F28-6000 and no F28-5000 were built. After being used by Fokker for a time, the F28-6000 were sold to Air Mauritanie, but not before they were converted to F28-2000s.
The most successful[why?] F28 was the F28-4000, which debuted on 20 October 1976 with one of the world's largest Fokker operators, Linjeflyg. This version was powered by quieter Spey 555-15H engines, and had an increased seating capacity (up to 85 passengers), a larger wingspan with reinforced wings, a new cockpit and a new "wide-look" interior featuring enclosed overhead lockers and a less 'tubular' look. The F28-3000, the successor to the F28-1000, featured the same improvements as the F28-4000.
F28s of Ansett Transport Industries' Western Australian intrastate airline, MacRobertson Miller Airlines of Western Australia, flew the longest non-stop F28 route in the world, from Perth to Kununurra, in Western Australia – a distance of about 2,240 km (1,392 mi). This was also the world's longest twin-jet route at the time.[when?] MMA'a F28's also had the highest utilisation rates at the time, flying over 8 hours per day.
By the time production ended in 1987, 241 airframes had been built.
- F.28 Mk 1000
- With a maximum capacity of 70 passengers, it was approved on 24 February 1969, the 1000C had a Main Deck Large Cargo Door.
- F.28 Mk 2000
- Mark 1000 with a fuselage stretch of 57 in (1.4 m) in front of and 30 in (0.76 m) aft of the wing, 79 maximum passengers, approved on 30 August 1972. Though it first flew on 28 April 1971 and successfully began revenue service with Nigeria Airways in October 1971, only ten were built.
- F.28 Mk 3000
- Mark 1000 with a 60 in (1.5 m) wing span extension, approved on 19 July 1978, with a 3000C variant with a large main deck cargo door. A successful variant, featuring greater structural strength and increased fuel capacity, it began revenue service with Garuda Indonesia.
- F.28 Mk 4000
- Approved on 13 December 1976, it is built on the longer Mark 2000, with two overwing exits on both sides, a 60 in (1,500 mm) wing span extension, and capacity for 85 passengers. The first prototype appeared on 20 October 1976 and it began service with Linjeflyg (Sweden) at the end of the year.
- F.28 Mk 5000
- Was to combine the shorter fuselage of the Mk 3000 and an increased wingspan. Leading edge slats were to be added to the wings and more powerful Rolls-Royce RB183 Mk555-15H engines were to be used. Although expected to be an excellent plane to operate on short runways due to its superior power, the project was abandoned.
- F.28 Mk 6000
- It first flew on 27 September 1973 and had the longer fuselage of the Mk 2000/4000 with an increased wingspan and leading edge slats. It was certified in the Netherlands on 30 October 1975. Two were built by 1976.
- F.28 Mk 6600
- Proposed version. Not built.
- Fairchild 228
- Proposed 50 seat American version to be assembled by Fairchild-Hiller with Rolls-Royce RB.203 Trent engines. Project cancelled.
In August 2006 a total of 92 Fokker F28 aircraft remained in airline service. Major operators included: MacRobertson Miller Airlines, Ansett Group Australia (more than 15), Toumaï Air Tchad (1), AirQuarius Aviation (3), SkyLink Arabia (1), Satena (1), Gatari Air Service (2), LADE (1), AirQuarius Aviation (4) and Merpati Nusantara Airlines (1). Biman Bangladesh Airlines (8). Some 22 airlines operated smaller numbers of the type. As of July 2018, Fly-SAX is the only airline operator of the F28 worldwide with 1 aircraft in service.
- Ghana Air Force (1)
- Philippine Air Force (1 – Used for domestic presidential Flights, The aircraft was named "Kalayaan")
- Togo (2)
