|F-27 / FH-227|
|A Fairchild Hiller FH-227B of VARIG at Congonhas Airport Sao Paulo in 1972|
|First flight||April 12, 1958 (F-27)
February 2, 1966 (FH-227)
|Number built||128 (F-27)
|Developed from||Fokker F27|
The Fairchild F-27 and Fairchild Hiller FH-227 were versions of the Fokker F27 Friendship twin-engined turboprop passenger aircraft manufactured under license by Fairchild Hiller in the United States. The Fairchild F-27 was similar to the standard Fokker F27, while the FH-227 was an independently developed stretched version.
Design and development
The Fokker F27 began life as a 1950 design study known as the P275, a 32-seater powered by two Rolls-Royce Dart turboprops. With the aid of Dutch government funding, the P275 evolved into the F27, which first flew on November 24, 1955. The first prototype was powered by Dart 507s and would have seated 28. To correct a slight tail-heaviness and to allow for more seats, the second prototype (which first flew in January 1957) had a 3-foot-longer (0.91 m) fuselage, which would allow seating for 32.
By this stage Fokker had signed an agreement that would see Fairchild build Friendships in the USA as the F-27. The first aircraft of either manufacturer to enter service was in fact a Fairchild-built F-27, with West Coast Airlines in September 1958. Other Fairchild F-27 operators in the U.S. included Air West and successor Hughes Airwest, Allegheny Airlines, Aloha Airlines, Bonanza Air Lines, Ozark Air Lines, Pacific Air Lines, Piedmont Airlines, West Coast Airlines and Wien Air Alaska. U.S. operators of the Fairchild Hiller FH-227 included Delta Air Lines, Mohawk Airlines, Northeast Airlines, Ozark Air Lines and Piedmont Airlines.
Fairchild F-27s differed from the initial Fokker F27 Mk 100s in having basic seating for 40, heavier external skinning, a lengthened nose capable of housing a weather radar, and additional fuel capacity. They also incorporated a passenger airstair door in the rear of the aircraft, operated by a flight attendant, which eliminated the need for separate stairs on the ground.
Developments were the F-27A with more powerful engines and the F-27B Combi version. The F-27B Combi passenger/freight version was operated in Alaska by Northern Consolidated Airlines and Wien Air Alaska.
Fairchild independently developed the stretched FH-227, which appeared almost two years earlier than Fokker's similar F27 Mk 500. The FH-227 featured a 1.83 m (6 ft 0 in) stretch over standard length F27/F-27s, taking standard seating to 56, with a larger cargo area between the cockpit and the passenger cabin.
In addition to the 581 F27s built by Fokker, 128 F-27s and 78 FH-227s were built. In February 2010, only one Fairchild FH-227 aircraft, FH-227E serial number 501 belonging to the Myanmar Air Force, remained in active service.

Of the 78 FH-227's built, 23 crashed.
- On 25 February 1962 an Avensa F-27A crashed into a mountain on Margarita Island killing all 23 on board.
- On March 10, 1967 West Coast Airlines Flight 720 crashed with four fatalities and no survivors near Klamath Falls, Oregon. The Fairchild F-27 was bound for Medford, Oregon from Klamath falls, and crashed due to ice accumulation on the aircraft.
- On 10 August 1968, Piedmont Airlines Flight 230 was on an ILS localizer-only approach to Charleston-Kanawha County Airport (CRW) runway 23 when it struck trees 360 feet from the runway threshold. The aircraft continued and struck up-sloping terrain short of the runway in a nose down attitude. The aircraft continued up the hill and onto the airport, coming to rest 6 feet beyond the threshold and 50 feet from the right edge of the runway. A layer of dense fog was obscuring the runway threshold and about half of the approach lights. Visual conditions existed outside the fog area. All three crew members and thirty-two of the thirty-four passengers perished. The National Transportation Safety Board blamed the accident on an "unrecognized loss of altitude orientation during the final portion of an approach into shallow, dense fog." The disorientation was caused by a rapid reduction in the ground guidance segment available to the pilot at a point beyond which a go-around could be successfully effected.
- On 25 October 1968 Northeast Airlines Flight 946, an FH-227, crashed on Moose Mountain near Hanover, New Hampshire on approach to Lebanon Municipal Airport. Of the 39 passengers and 3 crew on board, 32 were killed.
- On December 2, 1968 Wien Consolidated Airlines F-27B, N4905B, encountered severe to extreme turbulence near Pedro Bay, Alaska, resulting in separation of right wing and loss of all 39 on board. Pre-existing fatigue cracks contributed to wing failure. (NTSB DCA69A0006)
- On 14 March 1970 a Paraense Fairchild Hiller FH-227B registration PP-BUF operating flight 903 from São Luiz to Belém-Val de Cans, while on final approach to land at Belém, crashed into Guajará Bay. Of the 40 passengers and crew, 3 survived.
- On Friday 13 October 1972, Uruguayan Air Force Flight 571, an FH-227D carrying 45 people, crashed in the Andes mountains. The event became known as the "Andes flight disaster", and was the subject matter upon which the 1974 book Alive: The Story of the Andes Survivors and the 1993 film Alive were based.
- On July 23, 1973, Ozark Air Lines Flight 809 was operated by one of the company's Fairchild-Hiller FH-227's, registration N4215. The flight was scheduled to go from Nashville, Tennessee to St. Louis, Missouri, with 4 intermediate stops. The segments to Clarksville, Paducah, Cape Girardeau, and Marion proceeded normally. Crashed in storm downdraft on final approach to St. Louis. 38 fatalities, 6 survivors.
- On August 8, 1975, Wien Air Alaska F-27B, N4904, crashed into mountain on approach in bad weather at Gambell, Alaska, killing 10 and seriously injuring 20. (NTSB DCA76AZ004)
- On 29 March 1979, Québecair Flight 255, a Fairchild F-27, crashed after take-off killing 17 and injuring 7.
- On 24 January 1980, a Burma Air Force FH-227 crashed due to engine failure shortly after take-off, killing all but one of the 44 people on board. One person on the ground was injured.
- On 12 June 1982, a TABA – Transportes Aéreos da Bacia Amazônica Fairchild Hiller FH-227 registration PT-LBV en route from Eirunepé to Tabatinga on approach to Tabatinga collided with a pole in poor visibility and crashed onto a parking lot. All 40 passengers and 4 crew died.
- On 9 December 1982, an Aeronor Chile F-27A was operating as Flight 304 on a scheduled domestic service from Santiago to La Serena, Chile. On final approach to La Serena's La Florida Airport the aircraft stalled and crashed, bursting into flames on impact. All 42 passengers and four crew on board died.
- On 4 March 1988, a TAT European Airlines FH-227B operating a scheduled service from Nancy to Paris Orly as TAT Flight 230 crashed near Fontainebleau, France, killing all 23 occupants. An electrical malfunction during the start of the aircraft's descent had resulted in a sudden loss of control.
- On 6 June 1990, TABA Fairchild Hiller FH-227 registration PT-ICA flying from Belém-Val de Cans to Cuiabá via Altamira and other stops, while on approach under fog to land at Altamira, descended below the approach path, collided with trees and crashed 850m short of the runway. Of the 41 passengers and crew, 23 died.
- On 25 January 1993, TABA Fairchild Hiller FH-227, registration PT-LCS, operating a cargo flight from Belém-Val de Cans to Altamira crashed into the jungle near Altamira during night-time approach procedures. The crew of 3 died.
- On 28 November 1995, TABA Fairchild Hiller FH-227, registration PP-BUJ, operating a cargo flight from Belém-Val de Cans to Santarém crashed on its second attempt to approach Santarém. The crew of two and one of the passengers occupants died.
