French aircraft manufacturers have begun to develop a multipurpose aircraft model Wassmer WA 4 / 21 60-in the early years of the last century. The aircraft was positioned as a private aircraft, which, however, does not fit to use the aircraft as a means of commercial air, which is used as the aircraft for the transport of passengers on the routes of small extent, as a means of air taxi, as a tourist aircraft, etc.

Long enough for the aircraft design process Wassmer WA 4 / 21, though provided the aircraft high aircraft performance indicators, but in place in order and led to a significant rise in the cost of the aircraft, which did not provide the proper interest for customers, which is why the production of this aircraft has been very short-lived - for the entire period of manufacture aircraft manufacturers have been built just 25 aircraft of this model, although initially it was assumed that the serial production will amount to no less than 200 copies.

Designing an aircraft Wassmer WA 4 / 21 was carried out on the basis of the aircraft model Wassmer WA-40, moreover, experts believed that by improving the design and technical performance of the aircraft, will be able not only to provide a lower cost, but also to expand the use of this aircraft, however, for the above reasons, aviarazrabotchikov expectations did not materialize.

Aircraft Wassmer WA 4 / 21 has a fairly compact design of its fuselage, the aircraft that provides high maneuverability and excellent control, however, despite the possibility of operating the aircraft as a sports agent in the field, this model has not been applied.

The first flight of the multipurpose aircraft Wassmer WA 4 / 21 1967 held in the year, and due to the fact that the plane has successfully coped with all the necessary tests, the project was put into production.

At its board aircraft model Wassmer WA 4 / 21 can to transport four passengers, and, the presence of the plane coupled control system also provides the possibility of its use in educational and training purposes, however, to the greatest extent, this aircraft has proved itself as a particular plane where the model continues to operate to this day.

Because some features of the aircraft construction, transportation on board aircraft cargo is not possible, however, this factor is almost not played an important role in the performance features of the aircraft of this model.

Aircraft Wassmer WA 4 / 21 equipped powerplant brand Lycoming IO-540-C4B5, which is having a traction capacity of 250 hp, the aircraft provides an opportunity to accelerate to speed in 300 km \ h. (Cruising speed), which is quite acceptable, while the maximum rate of repetition of the aircraft is limited 1250 kilometers.
