__NOTOC__ 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 56 kW (75 hp) horizontally-opposed four-cylinder piston engine. An improved version with a more powerful engine (97 kW or 130 hp) was designated the HL-4, but this didn't sell either. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「CNNA HL-3」の詳細全文を読む スポンサード リンク
