Design of the Type 522 began in 1947 to replace the earlier Type 222 Vihor in the advanced training role. The new design featured a tricycle undercarriage and side-by-side seating for the student and instructor. As development progressed options were identified to allow the aircraft to fulfill other roles, including that of a four-seat light liaison aircraft (with a bench seat in the rear of the cockpit) and a civilian sport training aircraft.

An interesting design, especially with the 'car' doors. I would have preferred more all-round vision and easier escape if this was my trainer (especially if your spinning exercise goes wrong), but overall the specs look good.
