我国在1954年试制出的初级教练机初教五,是根据雅克-18飞机仿制的,起落架为后三点式。随着我国空军训练的进一步发展,对初级教练机的性能提出了更高的要求,并且要求起落架为前三点式。此时苏联已经研制出前三点式的雅克-18A,并将图纸送交中国。沈阳飞机设计室主任徐舜寿从培养、锻炼我国自己设计队伍,增强自行设计飞机能力出发,提出了自行设计一种新型的初级教练机——初教六的建议,并得到了上级批准。初教六飞机是双座、下单翼、前三点式的初级教练机,动力装置为一台额定功率285马力的活塞六甲发动机,配以双叶自动变距螺旋桨。初教六的机身、机翼和尾翼安定面为全金属结构, Our primary trial trainer produced in 1954 to teach five, is based on Jacques -18 aircraft imitation, landing gear for the latter three points. With the further development of our air force training, we have put forward higher requirements on the performance of the primary trainer and have required that the landing gear be the first three types. At this time the Soviet Union has developed the first three points of Jacques-18A, and the drawings sent to China. Xu Shun-shu, director of Shenyang Aircraft Design Office, proposed to design and develop a new type of primary trainer - CHU-6 from the perspective of cultivating and training China’s own design team and strengthening the capability of designing aircraft by himself. Cathay six aircraft are two-seater, under the wing, the first three-point primary trainer aircraft, a power plant for a rated power of 285 horsepower piston six engine, with double-leaf automatic pitch propeller. Primary six body, wing and stabilizer for the whole metal structure,
