Aerotécnica Aerotécnica was a Spanish aircraft manufacturer established in Madrid in 1954 to develop Jean Cantinieau's helicopter designs. After manufacturing small numbers of the AC-12 and AC-14, the firm ceased trading in 1962, as a consequence of lower cost for Spanish Air Force of US Helicopters, surplus of Korea War. Aircraft Aerotécnica AC-11 Aerotécnica AC-12 Aerotécnica AC-13 Aerotécnica AC-14 Aerotécnica AC-15 Aerotécnica AC-21 Aerotécnica AC-12 AC-12 Role - Light helicopter National origin - Spain Manufacturer - Aerotécnica Designer - Jean Cantinieau First flight - 20 July 1956 Primary user - Spanish Air Force Number built - 12 The Aerotécnica AC-12 Pepo is a Spanish two-seat light helicopter manufactured in 1956 by Aerotécnica. 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 1954. 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. Operators 1.

The AC-14 continued the Cantinieau practice of mounting the engine forward of the main rotor, and like the Norelfe, used the ducted exhaust from the turboshaft to counter the torque of the main rotor at low speeds, while at high speeds the exhaust gases were deflected rearwards to increase speed, torque being compensated for by movable twin tail fins. The first of prototype flew on 16 July 1957. A pre-production order for ten machines was placed by the Spanish Air Force where they served for a short time under the designation EC-XZ-4. No full production ensued, as they were much more expensive than second-hand Bell 47G-2 and G-3s. Operators 1. Spain Spanish Air Force - Ten pre-production aircraft only.
