The Hindustan HUL-26 Pushpak was a 1950s India n two-seat cabin monoplane designed and built by Hindustan Aeronautics Limited, based on the Aeronca Chief.[1]
Construction and operation
The Pushpak was a high-wing braced monoplane with a fixed tailwheel landing gear.[1] The fuselage was built from metal tubing, the wing aluminum ribs on a wooden spar, all covered in fabric.[1] The Pushpak first flew on 28 September 1958 and was powered by a 90 hp (67 kW) Continental flat-four engine.[1]
Around 160 aircraft were produced for Indian flying clubs for use as basic trainers.[1] Two examples were gifted to Malaysia and were later sold to private pilot owners in the United Kingdom. These examples remained in active operation in 2013.[2]
