The Antonov An-28 (NATO reporting name Cash) is a 2-engined light prop transport aircraft, developed from the Antonov An-14M. It was the winner of a competition against the Beriev Be-30 for use by Aeroflot as a short-range airliner. It first flew in 1969.

A total of 191 were built and 68 remain in airline service at August 2006.

After a short pre-production series built by Antonov, it was licence-built in Poland by PZL-Mielec-Mielec. In 1993, PZL-Mielec developed its own improved variant, the PZL M-28 Skytruck.

Development

The An-28 is similar to the An-14 in many of its aspects, including its wing structure and twin rudders, but features an expanded fuselage and turboprop engines, in place of the An-14's piston engines. The An-28 first flew as a modified An-14 in 1969. The next pre-production model did not fly until 1975. In passenger carrying configuration, accommodation was provided for up to 15 people, in addition to the two-man crew. Production was transferred to PZL-Mielec in 1978. The first Polish-built aircraft did not fly until 1984. The An-28 finally received its Soviet type certificate in 1986.
