The CNNA HL-1 is a multipurpose aircraft produced by the Brazilian manufacturer Companhia Nacional de Navegação Aérea .
History and construction
The CNNA HL-1 (sometimes referred to as the Muniz M-11) was a light, multi- role aircraft developed in 1940 in Brazil by Air Force Officer Antonio Guedes Muniz for the Brazilian aviation clubs. It was financed by the government (Campanha Nacional de Aviação), as this was the way to use pilots for military service. The machine was designed as a strutted shoulder wing with a non-retractable tail wheel landing gear. The fuselage consisted of a tubular steel and wood construction and, like the wings, was covered with fabric. In the cabin, which could be entered through a side door, the pilot and a passenger found space one behind the other. The machine was powered by a Continental-A65 - four-cylinder -Boxermotor with 48 kW. The prototype first took off on its maiden flight on June 18, 1940. After various improvements, the aircraft then went into series production as the HL-1B . Several machines were also sold in neighboring countries.
