The Nord 3400 Norbarbe was a French two-seat observation and casualty-evacuation aircraft built by Nord Aviation for the French Army Light Aviation.^[1]

Design and development

The Nord 3400 was designed to meet a French Army requirement for a two-seat observation aircraft, with a secondary casualty-evacuation role. The 3400 was a braced high-wing monoplane with a fixed tailwheel landing gear and an enclosed cabin with tandem seating for a pilot and observer. The prototype F-MBTD first flew on 20 January 1958, powered by a 179 kW (240 hp) Potez 4D-30 engine. A second prototype with an increased wing area followed, being powered by a 194 kW (260 hp) Potez 4D-34 engine. A production batch of 150 was ordered by the French Army in the same configuration as the second prototype.

Variants

Nord 3400-01: First prototype, powered by a 179 kW (240 hp) Potez 4D-30 engine, with, 12.7 m (42 ft) span/19.5 m² (210 sq ft) area, wings.^[2]
