CNNA HL-1

The CNNA HL-1 was a light utility aircraft developed in Brazil in 1940. It was a high-wing strut-braced monoplane with fixed tailskid undercarriage and seating for two persons in tandem.

Development

The design was developed by Henrique Lage as a two-seat cabin monoplane, bearing a strong resemblance to the contemporary Piper Cub. It was produced by the Cia Nacionale de Navegaçao Aéreo as the HL-1. Most of the aircraft were purchased by Brazilian aeroclubs, funded by the government's National Aviation Campaign to train pilots for military service. Production continued until 1950 and a small number were exported to neighbouring countries.
