The SAI KZ VII Lærke (Danish: "Lark") was a light utility aircraft built in Denmark shortly after the Second World War. Based on the SAI KZ III air ambulance, the KZ VII was a strut-braced, high-wing monoplane of conventional design with an enclosed cabin for four seats. Fifty-six aircraft were built, and another 22 partially completed aircraft were destroyed in a factory fire in 1947. The Danish Air Force operated 10 of the type as trainers between 1950 and 1977.
