Dutch engineer Joop D. Carley became a designer at “Nationale Vliegtuig Industrie (NVI)”, a company established in The Hague in 1922. His first aircraft developed at NVI was a monoplane with a 50 hp Gnome engine, designated as the Carley C.I. To the designer’s dismay, the aircraft was lost after an accident during its initial flights.
The Development of the Carley C.II
Following the accident, Carley returned to the biplane design, and the next aircraft, the Carley C.II, was built the same year. This was a two-seater, single-strut wooden biplane, equipped with an 80 hp French Gnome engine. The aircraft was primarily intended for pilot training, though it could also be used for other purposes.
A Unique Prototype’s Fate
Despite its potential, no orders were received for the aircraft, and it thus remained a single prototype. This biplane represents an early effort in Dutch aviation, marking an interesting chapter in the work of Joop D. Carley and NVI.
