The SAI KZ X was a light aircraft produced in Denmark for army co-operation duties in the early 1950s. It was a strut-braced, high-wing monoplane of conventional design with fixed tailwheel undercarriage and was derived from the KZ VII. Deliveries to the Danish Army commenced in 1952, but by the summer of that year, two had already crashed.

The investigations of these crashes were conducted with technical assistance from Britain's Royal Aircraft Establishment, but no underlying defect in the aircraft design was uncovered and the KZ X was returned to service. However, when two more crashes took place in 1954, the type was withdrawn from service. Most KZ Xs were scrapped, with the only surviving example now in the Danmarks Flymuseum.
