The Allstar SZD-54 Perkoz (English: Grebe) is a Polish two-seat, glider, designed and produced by Allstar PZL of Bielsko-Biała.[1]

Design and development[edit]

The SZD-54 was designed in 1991, but company and political upheaval in Poland resulted in the glider not being put into production until 2011.[1]

The aircraft is type certified to European Aviation Safety Agency CS22 standards. It features a cantilever mid-wing, a two-seats-in-tandem enclosed cockpit under a large bubble canopy and fixed monowheel gear with a small nosewheel and a tail caster.[1]

The aircraft is made from fibreglass. Its 20 m (65.6 ft) span wing has an area of 17.82 m2 (191.8 sq ft) and mounts air brakes, as well as winglets. Optional wing tips for 17.5 m (57.4 ft) with winglets are available, as are 17 m (55.8 ft) ones without winglets for aerobatics. All controls are automatically connected upon assembly. Despite its fixed landing gear, the SZD-54 has a best glide ratio of 42:1 with the 20 m (65.6 ft) span wing.[1]

The SZD-54 has a design airframe life of 15,000 hours and comes from the factory with a two year warranty.[2]

Operational history[edit]

By November 2012 two examples had been registered in the United States with the Federal Aviation Administration.[3]
