Carrying the NATO reporting name Cash, the An-28 is a development of the piston-engined An-14. It is a short-range twin-turboprop light general-purpose aircraft, expected to enter production with WSK-PZL-Mielec of Poland in 1980. The first prototype flew in September 1969 and had a retractable landing gear and Isotov TVD-850 engines. The An-28 now has a non-retractable tricycle type landing gear and two 723kW Glushenkov TVD-10B turboprops. A much larger cabin accommodates up to 19 passengers or a variety of alternative payloads, including scientific, medical or agricultural spraying equipment.
