Fokker Trimotor & Standard Airlines
Design and development:
In 1925, while living in the US, Anthony Fokker heard of the inaugural Ford Reliability Tour, which was proposed as a competition for transport aircraft. Fokker had the company's head designer, Reinhold Platz, convert a single-engined F.VII A airliner (a 1924 Walter Rethel design) to a trimotor configuration powered by 200 hp Wright Whirlwind radial engines. The resulting aircraft was designated the Fokker F.VII A/3M. Following shipment to the US, it won the Ford Reliability Tour in late 1925. The Trimotor's structure comprised a fabric-covered steel tubing fuselage, and a plywood-skinned wooden wing. The Fokker F.VII B/3M had a slightly increased wing area over the A/3M, with power increased to 220 hp per engine, while the F.10 was slightly enlarged, carrying 12 passengers in an enclosed cabin. The aircraft became popularly known as the Fokker Trimotor.
The 8- to 12-passenger Fokker was the aircraft of choice for many early airlines, both in Europe and the Americas. Along with the similar Ford Trimotor, itself having an all-metal design based on the World War I aircraft designs of German engineer Hugo Junkers, it dominated the American market in the late 1920s. However, the popularity of the Fokker quickly came to an end after the 1931 death of Notre Dame football coach Knute Rockne in the crash of TWA Flight 599, a Fokker F.10. The subsequent investigation, which revealed problems with the Fokker's plywood-laminate construction, resulted in the temporary banning of the aircraft from commercial flights, more stringent requirements for its maintenance, and the rise of all-metal aircraft such as the Boeing 247 and Douglas DC-2.
