The Norvigie two-seat observation post and liaison aircraft evolved from the civil NC.856 tourer and served in the observation crew training and reserve formations of the ALAT, and during 1963, twenty were transferred to the Armee de l’Air for the communication role after being re-engined with Lycoming O-320 or O-360 engines of similar output to the SNECMA-Regnier 4LO-4.
The first prototype NC.856 powered by a 105 hp Walter Minor 4-OOO flew on 12 March 1949, and after the liquidation of the parent company, the SNCA du Centre, development was taken over by the SNCA su Nord, a second prototype with a Regnier engine being flown on 15 March 1951. One hundred and 12 machines were subsequently manufactured for the ALAT, the first on on 12 March 1953.
