Design and development

edit

Aerotécnica AC-12 was designed by Jean Cantinieau and like other Cantinieau designs featured a distinctive "spine" above the fuselage pod that carried the engine ahead of the rotor assembly. Development costs were borne by the Spanish government, and the first of two prototypes took to the air on 20 July 1954.[1]

Operational history

Twelve (including two prototypes) were ordered for the Spanish Air Force where they served for three years under the designation EC-XZ-2.
