At the end of the twenties several examples were completely overhauled and equipped with an Armstrong-Siddeley Lynx rated 218 hp. Also a modification of the fuselage and the landing gear was done. This modified version was officially designated Fokker C.IA, but was also referred to as Fokker C.I Lynx. (Info: Wilco Jonker)

This C.I was fitted with an Armstrong Siddeley Lynx radial engine at some point from 1928. Written off in March 1935 following an emergency landing near Tilburg on 15 February 1935. Photo from: Nederlands Instituut voor Militaire Historie

Tenth anniversary of Schiphol as an airport. The original military airfield had six wooden hangars which stood near the eastern edge of the current general aviation platform. Hangar VI was used by KLM as its first passenger terminal. Photo from: Amsterdam City Archives

The C.I served in the Dutch army air force from 1920 until 1939, lastly as a trainer. This airframe was written off after flipping on its back on 16 June 1936, and this may be assumed to be that crash. It still has the original BMW inline engine. Photo from: Bodo Sandberg collection
