Five years have now elapsed since the last report on helicopter development in France was given by Francois Legrand, then Chief of the Rotary Wing Section at the “Service Téchnique de l'AéYonautique”. At that time, Sud-Aviation had been in existence for two years and the production of helicopters was at an early stage, with almost only French operators. In 1963, Mr. Legrand became Sud-Aviation helicopter chief designer; since 1959, the position of France in the helicopter production world has asserted itself considerably.
