The Antonov An-28 is a twin-engine turboprop aircraft that was developed by the Antonov Design Bureau in the Soviet Union for short-range transport and regional airliner roles. It is a derivative of the Antonov An-14, with a longer fuselage, a T-tail, and more powerful engines.

The An-28 was first flown in 1969 and entered service in 1975. It was used by Aeroflot and other operators in the Soviet Union and abroad for passenger, cargo, mail, and special missions. It can carry up to 18 passengers or 1,500 kg of payload, and it has excellent short takeoff and landing (STOL) capabilities2. It has a maximum speed of 350 km/h and a range of 1,365 km.

The An-28 is also known by its NATO reporting name Cash. It was produced in Ukraine until 1986, and then licensed to Poland’s PZL Mielec, where it was built as the M28 Skytruck until 2019. The M28 had improved avionics, performance, and versatility, and it was exported to several countries in Europe, Asia, Africa, and America4. It was also used by the Polish Air Force and Navy for transport, patrol, and search and rescue missions.

The An-28 is one of the most successful regional aircraft in its class, and it has proven its reliability and adaptability in various conditions.
