The CNNA HL-6 was a trainer aircraft from the Brazilian manufacturer Cia Nacionale de Navegaçao Aéreo .
History and construction
The HL-6 was designed as a cantilever low-wing aircraft in a conventional configuration. The pilots sat one behind the other in open cockpits. The fuselage, like the wings, was made of a wooden frame and covered with fabric. The machine had a fixed tail wheel chassis. It was powered by a Lycoming O-290C boxer engine with 93 kW. In 1943 5 series aircraft were produced under the designation HL-6A with a more powerful engine and in 1944 39 HL-6B Carué with Franklin 6AC-298 F with 97 kW and an optional closed cabin.
