[edit] Design and development

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 1956.

[edit] Operational history

Twelve were ordered for the Spanish Air Force where they served for a short time under the designation EC-XZ-2.
