Start of production of the F-27 at Fokker (excerpt from a Dutch newsreel from 1955)

The Fokker F-27 Friendship is a propeller - airliner of the former Dutch aircraft manufacturer Fokker .

history

Development began in the 1950s to replace the Douglas DC-3 . The result was a shoulder - wing aircraft with two Rolls-Royce Dart engines and a pressurized cabin for initially 28 passengers. The first prototype flew on November 24, 1955. The second prototype was lengthened by about one meter in the front area, as the aircraft had proven to be tail-heavy in flight tests. The first production model, the F-27-100 , carried 44 passengers and was delivered to the first customer, the Irish Aer Lingus , in 1958 . The F-27-200 was created with a more powerful engine . The most famous model F-27-500 was given a 1.5 m longer fuselage and space for 52 passengers. It first flew in November 1967.

In 1956, Fokker signed a contract with the US company Fairchild to manufacture and sell the aircraft for the North American market. The first US- built Fairchild F-27 flew on April 12, 1958.

In the early 1980s, the Dutch manufacturer developed the Fokker 50, a successor to the F-27.

The third production machine, an aircraft from the F-27-100 series , is now on display in the Aviodrome Museum in Lelystad, Netherlands . The museum also owns parts of the prototype.

In February 2007, a decommissioned F-27 was sunk in the sea off Curaçao , the largest island in the former Netherlands Antilles , near the former fishing village of Westpunt. It serves as an artificial reef and is an attraction for divers.

Incidents

From 1960 to March 2020, 177 Fokker F27s were destroyed, 165 of them in accidents. 88 of these incidents resulted in a total of 1,574 deaths. Examples:

  • On January 25, 1970, an F-27-200 of Royal Nepal Airlines ( aircraft registration number 9N-AAR ) got into a severe thunderstorm with turbulence and heavy squalls after a flight from Kathmandu , Nepal during the final approach to Delhi-Palam airport . The pilots lost control of the plane; it crashed three kilometers east of the airport. One crew member was killed, all other 22 occupants survived.
  • On September 26, 1972, a Fokker F-27-600 from Garuda Indonesia (PK-GFP) , which was taking off on a test flight from Jakarta-Kemayoran Airport, suddenly rolled to the right when taking off at a height of 30 meters and fell 90 meters next to it Runway into the area. There was only a three-person crew on board, who were killed in the accident.
  • On July 20, 1981, a Fokker F-27-600RF Friendship of Somali Airlines (6O-SAY) on a flight from Mogadishu to Hargeisa got into extreme turbulence eight minutes after take-off, as a result of which it went into a flat spin, in which the structural Load limits have been exceeded. Part of the right wing broke off in midair, and the machine then fell to the ground. All 50 occupants died (see also Somali Airlines flight 40 )
  • On April 20, 1985, an F27-100 (YN-BZF) bought by the Nicaraguan airline Aeronica had an accident on its transfer flight from Europe to Nicaragua about 280 kilometers west of Kulusuk Airport in Greenland. After refueling in Kulusuk, there were problems pumping the fuel from the additional tanks to the engines. Therefore, the crew decided to return to Kulusuk, but could not find the airfield due to bad weather. In the emergency landing in the snow near a radar station came from the five crew members of two killed (see also air accident of Aeronica in Greenland ) .
  • On August 25, 1989, a Pakistan International Airlines (AP-BBF) F-27-200 disappeared on a flight from Gilgit to Islamabad with 54 occupants. The last radio message was received four minutes after take-off. The wreck of the machine has not yet been found; a crash in the Himalayas is considered likely.
  • On February 12, 1990 there was an accident with a Fokker F-27-200 of the TAM Linhas Aéreas (PT-LCG) , in which three people died. A flight captain in training initiated the descent to Bauru Airport too late. The instructor flying on the flight requested that the approach be continued despite the excessively high altitude and the excessively high airspeed. When the flight captain was unsure, the instructor took over the controls. The plane touched down on the runway too late. During the subsequent go-around, the machine was accelerated too abruptly, which led to a misfire, the Fokker fell back to the ground and collided with a car. Two occupants of the car and the flight captain were killed, while 40 occupants of the plane survived the accident (see also the flight accident of the TAM Linhas Aéreas in Bauru 1990 ) .
  • On February 24, 1990 on board a Fokker F-27-600 of the German FTG (D-AELB) the engine failed on both sides and the right engine was torn off the wing. The crew had previously practiced stalling in the landing configuration as part of a training flight, whereupon the engines reacted with overheating and vibrations. The subsequent emergency landing in a field near Bergisch Gladbach, about 12 kilometers north of the starting airport Cologne / Bonn , was successful and the two-man crew managed to get to safety, but the machine burned out and had to be written off.
  • On June 16, 2004, an F-27-200 operated by Pakistan International Airlines (AP-AUR) rolled over the end of the 1,768 m long runway at Chitral Airport and was irreparably damaged. All 40 occupants survived the accident.
  • On July 10, 2006, a Pakistan International Airlines (AP-BAL) F-27-200 crashed shortly after taking off from Multan . All 45 people on board were killed. Despite an engine failure, the captain had continued take-off during the take-off run; it came to a stall. The engine damage itself was caused by maintenance errors.
