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 (written with a dash) 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 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, Allegheny Airlines, Aloha Airlines, Bonanza Air Lines, Hughes Airwest, Pacific Air Lines, Piedmont 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fairchild F-27」の詳細全文を読む スポンサード リンク
