aircraft

The first flight, flown by the testpilot

Joachim von Köppen, took place on

the 20th April 1934.

During those first flights it became

clear that it was an impressive

aircraft and had excellent

performance and flight properties.

With 80 HP it was a bit

underpowered but despite that the

flight characteristics were

overwhelming. An other point was the low fuel

consumption, the easy maintenance

and the low purchase price. The

aircraft had been developed as a

basic trainer and had incredible

aerobatic qualities. Already in 1935 the first aircraft had

been delivered abroad. Switzerland

ordered three aircraft and had been

granted the licence to build those on

their own.

The Swiss Airforce used those

aircrafts until 1974 as a basic trainer

for their studentpilots.

The last original Bü- 131 had been

build in the mid 60s in Spain, a

CASA 1.131.

Of the approximately 5000 build

airplanes, only nearly 200 of these

Jungmanns still exist worldwide. From 1994 on, a small company in

Poland, the H.A.S. from Jasienica

started to build the Bucker again. 28

planes were build in total and

production ended 2006 after the

death of the company founder

Janusz Karasiewicz.

But this was not the end. Another

company from Poland, Air Res

Aviation form Rzeszów/ poland,

bought the licences and plans from

Janusz widow and restarted the

production. The first aurcraft had its

maidenflight in december 2012 and

2 more are in production right now.
