History

Developed from	Fokker F.VII

TheFokker F-10 was an enlarged development of theFokker F.VII airliner, built in the late 1920s by theFokker Aircraft Corporation of America. It was atrimotor passenger aircraft, and it carried 12 passengers. This was four more than the F.VII it was based on, and it had a larger wing and more powerful engines than that design. A crash of this aircraft in 1931, led to widespread reforms in the U.S. aviation industry and hurt the reputation of wooden winged' aircraft, especially the Fokker Tri-motor types.

Operational history

[edit]

Fokker built 65 for commercial and military service. Afterthe crash of a Transcontinental & Western Air F-10 in 1931, killingNotre Dame football coachKnute Rockne and seven others, which was caused by the deterioration of the wooden wing spar, the type was temporarily grounded, and it was required to undergo more frequent and rigorous inspection. Its public image was also greatly damaged, leading to its early retirement from U.S. airlines.
