Bücker Bu.131 "Jungmann"

Bücker Bu.131 "Jungmann"The Bücker 'Jungmann' is a biplane designed for instruction of pilots between the First and Second World War but which had a similar role long after the period. The 'Jungmann' is German by origin but its designer, Anders Anderson, is Swedish. It was built in substantial numbers in Germany, Spain and even in Japan. The plane was operated very successfully by civil flying schools and by the Luftwaffe. In its era the Bücker was of a most interesting construction. With its narrow wing chord and slim profile it achieved a remarkable speed of 180 km/hr powered by an engine of just 105 hp, about fifty percent faster than its contemporaries.
A few notable construction details are the four (!) ailerons, which are attached to the wings with self-aligning ball bearings, and the activation of the ailerons, elevator and rudder which is effectuated by pushrods instead of the usual cables. This makes the 'Jungmann' a very sensitive plane. Most of the "Jungmanns" presently still flying were built in Spain by CASA who kept the model in production until 1960. It was on active duty with the Spanish air force as late as 1984.

The Early Birds "Jungmann"
The "Early Birds" Bücker "Jungmann" was aquired in the same way as the Tiger Moth, after a number of engine overhauls for a French organisation. The aircraft was built in Spain in 1954 as Casa 1.131È and is powered by an Enma 'Tigre' engine, a license built De Havilland Gipsy Major. It bears the US-registration N131EB.
Presently it is suspended from the hangar ceiling because of limited space. However plans are to fly the aircraft again in 2005 since a grass strip is available for historic planes in Lelystad.
