The PWS-21 was a Polish passenger aircraft for 4 passengers, built in PWS factory in 1930, that remained a prototype. The aircraft was developed for a contest for a successor of Junkers F-13 in LOT Polish Airlines. The first design of 1929, named PWS-21, developed by Stanis aw Cywi ski and Jaros aw Naleszkiewicz, was a braced high-wing plane, but it was not realized because LOT demanded bigger passenger cab. The next design, named PWS-21bis, was a cantilever high-wing plane, similar to Fokker F.VIIa/1m design. The only prototype (markings SP-AEC) first flew in the spring, probably April of 1930 in Bia a Podlaska. Its counterpart was Lublin R-XI.
