The Payen Pa.47 Plein Air (English: Open Air) or Week End ^[1] was a French two seat, high wing single engine tourer, which first flew in 1949. Only one was built.

Design and development

Most of Roland Payen's aircraft were tailless designs but the Plein Air was strikingly conventional. It was a strut-braced high wing monoplane, seating two side-by-side in a cabin under the wing leading edge and powered by a 48 kW (65 hp) Continental A65 air-cooled flat-four engine. The wings were rectangular in plan and the lift struts were V-form pairs from the lower fuselage. ^[2]

The Plein Air had a flat sided fuselage which tapered to the tail. This was conventional, with a straight edged fin and rudder with a rounded top. Its tailplane was strut braced to the fin. The tourer had a fixed tail wheel undercarriage with main wheels on split axles mounted on the central fuselage underside; the legs were faired-in V-struts from the lower fuselage. The tail wheel, mounted on a telescopic leg, was also faired. ^{[2] [3]}

Its first flight was on 18 June 1949 but it did not receive its Certificate of Airworthiness (C of A) until 24 August 1957. Initially registered with Payen, it changed hands in July 1960 but its C of A ran out in July 1962 and was not renewed. ^[4]
