CNNA HL-3
Script error: No such module "Unsubst". Template:Infobox aircraft
The CNNA HL-3 was a civil trainer aircraft developed in Brazil in 1941.
Development
CNNA had already benefited from the Brazilian government's decision to invest in a pilot training campaign and hoped that a dedicated trainer aircraft would attract even more sales. To that end, the HL-3 was proposed, and one prototype was constructed and flown. Unfortunately for the firm, this was not to be the case, and no official interest was shown.
The HL-3 was a two-place light aircraft powered by a Template:Cvt horizontally opposed four-cylinder piston engine.
An improved version with a more powerful Template:Cvt engine was designated the CNNA HL-4, but this didn't sell either.
