Bü-131 Jungmann

Designed by Carl Bucker the Jungmann, meaning “Young Man” or “Freshman” in English, was one of the finest primary aerobatic trainers ever built. Its flying qualities are splendid and its distinctive double swept-back wings made it a great snapping airplane. With its lightweight and agility, combined with its 12 “G” strength it became “the” aircraft for primary training in the mid-thirties. It was used by the German Luftwaffe and was adopted by Switzerland, Czechoslovakia, Hungary, South Africa and Spain before World War II. During and after the war, many other countries bought or built them under license including Yugoslavia, Brazil, Uruguay, Chile, and Japan.

The Jungmann is a simple airplane whose upper and lower wings are interchangeable, making them faster to manufacture and repair. Each wing panel uncovered weighs only 25 lbs(13 kg). The resulting four ailerons contributed to its manoeuvrability and came in handy to several Jungmann pilots. A famous incident involved German pilots who found themselves surprised by British fighters over Paris. All but one managed to escape by making tight turns around the Eiffel Tower.

After World War II, most German Jungmanns were destroyed; however, because it was such a good aircraft the Swiss Air Force continued to use them as training aircrafts until the early 1960’s. At that time they were still being manufactured in Spain. As the Air Forces gradually retired them, private owners around the world started collecting them where they are appreciated to this very day.

Our plane

In Czechoslovakia, 300 BU-131 were built between 1939 and 1947. These were delivered to flying clubs and to the Czechoslovakian Air Force, one of which is in this collection. This specific aircraft with the serial number S/N: 114/L591 was built in 1947 and the original Hirth engine was replaced with a Lycoming Ο-360-Α4Α when the aircraft was repaired in the U.S.A. It was purchased by the Athenian Aviators Collection from the American collector Ray Strassel with the registration number N-111A.

It has now logged 870 hours of flight since production.
