Fokker 100 is a medium-sized aircraft developed and manufactured by the Fokker company. Introduced in 1980s, the aircraft has low operational costs and no competition and was a best-seller in the 100 seat category.

In 1983 the design of the Fokker 100 was announced as an extended replacement of the Fokker F28. The United States Federal Aviation Administration certified the aircraft as Fokker 28-0100, even though many parts of the two designs were similar.

In November 1986 the first prototype, PH-MKH, made its maiden flight. The second prototype, PH-MKC, flew in February 1987. The first Fokker 100 was delivered to its launching customer, SwissAir, in February 1988.

The airline crisis in 1990s and competition from the Bombardier CRJ200 and Embraer ERJ 145 adversely affected Fokker 100 sales and the company became insolvent in 1996. Production was wound up in 1997. In total 278 aircraft were manufactured. As of 2009, 30 airlines were operating 229 Fokker aircraft.

“Companies such as Bombardier and Rekkof Restart tried to restart production of the aircraft.”

Companies such as Bombardier and Rekkof Restart tried to purchase and restart production of the aircraft, but negotiations failed. Suppliers of the aircraft set up the Fokker 100 programme to provide after-sales service to customers.

In February 2009, as a part of the programme, Stork Aerospace, the parent company of Fokker Services, entered into a manufacturing licence and forging supply agreement with Messier-Dowty for the replacement of the Fokker 100’s landing gear.

Messier-Dowty signed a contract with Heroux-Devtek to manufacture and supply replacement components. Deliveries will begin in 2010 and end in 2012. The value of the contract is estimated to be $11m to $17.7m.

Orders and deliveries

The key customers of the Fokker 100 were American Airlines, which bought 75 aircraft, TAM Airlines (previously TAM Transportes Aéreos Regionais), which bought 50 aircraft, and US Air, which bought 40 aircraft.

Features

A Fokker 100 provides seating for 109 passengers. The standard aircraft is 8.5m high, 35.53m long and has a wingspan of 28m. It has a wing area of 93.5m², a main wheel track of 5m and a wheel base of 14m.

A basic Fokker 100 aircraft has a maximum ramp weight (MRW) of 44,680kg, a maximum take-off weight (MTOW) of 44,450kg and maximum landing weight of 39,915kg. It has a maximum payload capacity of 11,240kg and a fuel tank capacity of 10,293kg.

The economic design life of the aircraft is 90,000 landings or flight hours. Most of the aircraft reach 3,500 flying hours per year.

Variants

“The Fokker 100 is equipped with a flight management system and an integrated automatic flight control system.”

An extended range version of the Fokker 100 with additional fuel tanks was introduced in 1993. In 1994 a passenger / freight version, the Fokker 100QC, was launched.

A shorter version of the F-28, a new variant Fokker 70, was introduced in 1993 with seating for 80 and a reduced fuselage.

In 1994 and 1997 a shorter version of the Fokker 100, the Fokker 70 five-abreast regional aircraft, was launched. A total of 47 aircraft were manufactured during this period. Eight airlines operate the aircraft.

Cabin

The Fokker 100 has two cabin configurations. One is the 109-seater economy class layout with five seats in a row and the other is the business class layout with four seats in a row. A typical cabin layout has 107 seats at 32in pitch. The aircraft has upper deck compartments toward both sides of the entry door offering higher payload capacity. It also has a forward-opening passenger door or a downward-opening door with integrated stairs.

Flight deck

The Fokker 100 is equipped with a flight management system and an integrated automatic flight control system in its glass cockpit. The systems enable CAT IIIA autoland and offer full flight envelope protection. CAT IIIB with roll-out guidance is also available. Other flight deck systems including BRNAV, EGPWS, RVSM, 8.33kHz / NAV and COM FM-immunity and TCAS II are all certified on the aircraft.

Engines

Fokker 100 runs on Rolls-Royce Tay 620 or Tay 650 engines. The first 36 aircraft were fitted with Tay 620 engines and aircraft built later run on Tay 650 engines. Both engines offer high fuel efficiency, performance, reliability and low noise and emission levels.

“Fokker 100 complies with ICAO chapter three noise regulations.”

The Tay 620 engine weighs 3,135lb and delivers a maximum take-off thrust of 13,850lb. The engine is 94.8in long and has a fan diameter of 44in. At full passenger payload the engine has a range of 2,020nm.

The Tay 650 engine delivers a thrust of 15,100lb and weighs 3,340lb. It is 94.8in long and has a fan diameter of 44.8in. At full passenger payload the engine has a range of 1,680nm.

Performance

At a maximum payload of 11,240kg the Fokker 100 can traverse at a range of 1,600nm. At an MTOW of 45,810kg and maximum payload capacity the aircraft has a range of 2,200nm.

Environment

Fokker 100 complies with ICAO chapter three / FAA stage three noise regulations as well as chapter four regulations. To further reduce noise a fully automated noise abatement profile (NAP) is available. The aircraft also complies with the CAEP 4 emission level requirements.
