The IPT-16 Surubim was a Brazilian single-seat, single engined experimental light aircraft. A single example was built and flown in 1959.
In 1949, Joseph Kovács, a Hungarian-born aircraft engineer working at the Instituto de Pesquisas Tecnologicas (IPT - Institute of Technical Research) [1] of the University of São Paulo proposed to design and build an experimental high performance light aircraft powered by a surplus Hirth HM 506 engine that had been imported into Brazil before the Second World War for use in an unbuilt aircraft design. The IPT, however, was busy on other projects, and so did not back Kovács' proposed design. Kovács, with fellow IPT engineer Sylvio de Oliveira, started construction of the design, named "Surubim" (little devil), in a rented workshop. [2]
The Surubim was a low-winged monoplane with a retractable tailwheel undercarriage of all wooden construction with plywood skinning, using Brazilian Pine and Freijo, two indigenous woods. The wings were fitted with trailing edge flaps and fixed leading edge slots. The pilot sat in an enclosed cockpit. [1] [2]
When Kovács left IPT in 1951, de Oliveira continued work on the prototype, which was acquired by the IPT in 1953 for use as a flying test bed, gaining the designation IPT-16. Construction of the prototype continued at a slow pace, with the prototype being shown at an exhibition in São Paulo in 1956, but remained unflown for several more years. [2]
The IPT-16 finally made its maiden flight on 17 September 1959. [2] Despite being underpowered and using a fixed pitch wooden propeller, performance was good, reaching a level speed of 340 km/h (210 mph) and 500 km/h (310 mph) in a dive. It was used by the IPT for three years, after which it was transferred to the Rio Claro City Aero Club for use as an aerobatic aircraft, where it remained in use until at least 1977. [2]
It was presented to the Museu Aeroespacial at Rio de Janeiro in 1988, where, after restoration, it was put on display. [3] [4]

The Pilatus P-3 was a military training aircraft built by Pilatus Aircraft of Switzerland.
The Heinkel He 116 was an extremely long-range mail plane designed to deliver airmail between Germany and Japan. Several examples were built for this role, as well as a small batch to be used in the long-range reconnaissance role.
The Embraer EMB 121 Xingu is a twin-turboprop fixed-wing aircraft built by the Brazilian aircraft manufacturer, Embraer. The design is based on the EMB 110 Bandeirante, using its wing and engine design merged with an all-new fuselage. The EMB 121 first flew on 10 October 1976.
The Miles M.33 Monitor was a twin-engined British target tug aircraft designed and built by Miles Aircraft towards the end of the Second World War. Intended for use by the Royal Air Force and the Fleet Air Arm, the aircraft did not enter service with either.
The Foster Wikner Wicko was a 1930s British two-seat cabin monoplane built by the Foster Wikner Aircraft Company Limited at Southampton Airport, Hampshire.
The Aeronca Model 9 Arrow was a low-wing all-metal cabin monoplane with retractable landing gear. It was marketed to returning pilots from World War II and unveiled in 1947 but never went into production.
The Auster Avis was a four-seat light aircraft developed from the Auster Autocrat. It featured a redesigned fuselage incorporating four doors and a circular cross-section towards the tail, new undercarriage, and new wing flaps. It was planned in two versions, the Mk 1 for civil use, and the Mk 2 for military and air ambulance duties. However, only two prototypes were built, and Auster abandoned the project in favour of the Auster J-5 Autocar.
The Klemm Kl 107 was a two-seat light aircraft developed in Germany in 1940. It was a conventional low-wing cantilever monoplane of wooden construction with fixed tailwheel undercarriage. Wartime production totalled only five prototypes and some 20 production machines before the Klemm factory was destroyed by Allied bombing. Following World War II and the lifting of aviation restrictions on Germany, production recommenced in 1955 with a modernised version, the Kl 107B, of which Klemm built a small series before selling all rights to the design to Bölkow. This firm further revised the design and built it as the Kl 107C before using it as the basis for their own Bo 207.
The LIBIS KB-6 Matajur was a 1950s Slovenian two-seat light monoplane designed and produced by LIBIS aircraft during Yugoslavian period.
The CNNA HL-6 was a civil trainer aircraft developed in Brazil in 1943.
The Zlín Z-XII was a Czechoslovak two-seat sports aircraft, and the first major design success by the Zlínská Letecká Akciová Společnost (Zlín) aircraft manufacturing company, after its founding in Otrokovice after the takeover by the Bata Group.
The Hispano HS-42 and its derivative, the HA-43, were advanced military trainer aircraft produced in Spain in the 1940s. The basic design was that of a conventional, low-wing, cantilever monoplane with seating for the pilot and instructor in tandem. The HS-42 had fixed, tailwheel undercarriage with spatted mainwheels, while the HA-43 had retractable main units. Produced on the assembly line that had been used to build Fokker D.XXI fighters, the HS-42 shared some components with this aircraft.
