Skandinavisk Aero Industri A/S was a Danish manufacturer of aeroplanes that existed between 1937 and 1954. The company was founded by technician Viggo Kramme (1905–1984) and engineer Karl Gustav Zeuthen (1909–1989) and based in Copenhagen.
The company's aeroplanes were labelled "KZ" for Kramme and Zeuthen, the first being the KZ I from 1937. The KZ IV was built as an ambulance plane for Zone-Redningskorpset and introduced in 1944. Post-war sales never reached the company's expectations, and production turned unprofitable in the early 1950s, driving the company to shutdown. In total, about 200 planes were built by the company.
A number of the KZ planes have been preserved. As of 2009, Dansk Veteranflysamling (The Danish Collection of Vintage Aircraft) exhibits a specimen of each of the 11 aircraft models manufactured by the company.
KZ VII is a 4-seat development of KZ III. The prototype had its maiden flight 11th November, 1946. There was 56 planes built of the type.
In 1947 the KZ VII was full production a fire at the SAI factory in February destroyed 22 aircraft on the production line.
In 1948 it 10 KZ VII was delivered to the Danish Air Force. Originally, these aircraft were fitted with 125 hp engines, but they were later replaced by 145 hp engines. The Air Force operated the type as trainers until 1950 and thereafter until the phase out in 1977 as liason aircraft.
Civilian aircraft was used as trainers and private use. Some were exported, to Finland and Switzerland, where they still fly. - There are still a dozen KZ VII in the Danish registry.
