SAI / Skandinavisk Aero ZK.VII Lærke




Designed by Viggo Kramme and Karl Gustav Zeuthen, 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. The wings were made of wood, althoughly covered mainly in fabric.




First flown on 11 November 1946, fifty-six aircraft were built by Skandinavisk Aero Industri, 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.
