The PZL-Mielec M-20 Mewa (Polish: Gull) is a licence-built version of the Piper PA-34 Seneca II manufactured in Poland by WSK PZL Mielec in a limited series from the 1980s.

Despite the fact that it won the Teraz Polska award in 1993, interest was very limited and only 33 had been built by the end of 1998.

[1] In April 2015, Aero AT (Jiangsu) Aviation Industrial bought the intellectual property for the M-20 Mewa from U.S.-based Sikorsky Aircraft's subsidiary PZL Mielec in Poland.

The plan being for Jiangsu Aero to assemble the M-20 Mewa in China at the Changzhou Konggang Industrial Park.

The first Chinese produced M-20 Mewa was expected to roll off the production line at the facility in 2017, followed by 50 aircraft annually starting in 2018.
