Aerotécnica AC-14

__NOTOC__The Aerotécnica AC-14 was a Spanish five-seat light helicopter of the 1950s, designed by Jean Cantinieau, based on enlarging his Nord Norelfe design.

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.

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 the second hand Bell 47 G-2 and G-3 (leftover of the Korean War).
