Design and development edit
The KR-03 was designed as an ab initio training glider.[1] The name Puchatek is Polish translation of Pooh Bear.[3]
The aircraft is made from aluminium with some parts covered in doped aircraft fabric covering. Its 16.4 m (53.8 ft) span wing employs a Wortmann FX S-02-158 airfoil. The wing features top and bottom Schempp-Hirth-style dive brakes. The landing gear consists of an oleo-pneumatic sprung, non-retractable main wheel, a tail wheel and a rubber sprung nose skid. The Puchatek has a baggage compartment with a capacity of 5 kg (11 lb) for soft baggage items.[1][2][4]
The aircraft was type certified in the United States on 6 August 1991, with Barry Aviation of Edgewater, Volusia County, Florida as the US certificate holder.[2]

In 1993, a few examples were put into service with the Australian Air Force Cadets (AAFC), totalling to three as of 2012. They are currently assigned to 2 Wing AAFC. They are still in service as of 2014.[5]
As of August 2011 there were 16 KR-03As registered in the United States with the Federal Aviation Administration[6] and in August 2022 there were 10 KR-03As registered.[7]
