Antonov An-28 & PZL M28

The Antonov An-28 is a twin-engined light turboprop 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 16 remain in airline service as at August 2015.

After a short pre-production series built by Antonov, it was licence-built in Poland by PZL-Mielec.

In 1993, PZL-Mielec developed its own improved variant, the PZL M28 Skytruck.

Production was transferred to PZL-Mielec in 1978

The An-28 is similar to the An-14 in many 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 preproduction 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.
