The PZL Krosno KR-03 Puchatek is a Polish mid-wing, T-tailed, two-seats-in-tandem, glider that was designed by Jerzy Krawczyk and Eugeniusz Pelczar and produced by PZL Krosno, first flying in 1985.[1][2]

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]
