The Casmuniz 52 was a twin-engine light transport aircraft. It was the first all-metal aircraft built in Brazil, only the prototype was built.
The plane began to be designed by Willibald Weber in 1951, an Austrian pilot and aeronautical engineer born in Wiener Neustadt in 1925, and where work for Messerschmitt until 1944.[1] In 1949, he moved to Brazil, and worked for Cássio Muniz S/A. He was based on the Aero 45, which he had already maintained and designed a five-seat twin-engined cabin monoplane which was first flown in April 1952.[1] A low-wing cantilever monoplane with a 185 hp (138 kW) Continental E185 flat six engines mounted on the leading edge of wing.

After accumulating 200 flight hours, the aircraft was sent to the Department of Aerospace Science and Technology, where it received its certification in 1955.[2]
The company offered Cessna the proposal of creating an assembly line for its aircraft in Brazil, so that they could also produce the Casmuniz 52 in series, the proposal was refused because the American company was already negotiating a factory in Argentina.[2] After, the airplane was sold to Weber that left the company to found the OMAREL, where he made modifications and used the airplane intensively from 1957 until 1958.[2] With the end of his company's activities, the airplane passed by several owners.[2]
