The PIK-11 Tumppu ("Mitten") was a single-seat, single-engine sport aircraft developed in Finland in the 1950s.[1] It was a low-wing, cantilever monoplane of conventional design with an enclosed cockpit and fixed, tailwheel undercarriage.[2] It was to be the first powered aircraft produced by Polyteknikkojen Ilmailukerho,[1] with the objective being building an aircraft for club use that was cheap to build and easy to fly.[2] Design work was started in 1948 by Kai Mellen and Ilkka Lounanmaa under the direction of Professor Arvo Ylinen.[2] The first of four machines made its first flight on 15 March 1953.[2] The prototype is preserved at the Finnish Aviation Museum,[3] and another example was still listed on the Finnish Civil Aviation Authority registry in 2008.[4] In the early 21st century, a flying replica was under construction, to be powered by a Rotax 912 engine.[5] Specifications{{Aircraft specs|ref=Jane's all the World's Aircraft 1955-56[6] & [7] |prime units?=met
