PZL M-26 Iskierka

PZL M26 Iskierka (sparklet) or M26 Airwolf is a Polish trainer and aerobatics aircraft, designed in WSK "PZL-Mielec" (later PZL Mielec).

Design and development

M26 Iskierka was conceived as an economical plane for civilian pilots' training and primary selection of military pilots. It offers training in both VFR and IFR flying and aerobatics. Its construction is partly based upon twin-engine PZL M-20 Mewa utility plane (Piper Seneca II, built under licence in WSK-Mielec). It shares vertical stabilizer with rudder and main landing gear with Mewa, while wings and tail part of fuselage are unified to some degree. The plane is constructed according to FAR-23 rules. Main designer was Krzysztof Piwek.

The first prototype M26-00, powered with PZL-Franklin 6A-350C1 (150 kW) engine flew first on July 15, 1986 (registraion SP-PIA). The second prototype, of ultimate M26-01 variant, with Lycoming AEIO-540-L1B5D (220 kW) engine flew on June 24, 1987 (registration SP-DIB, earlier SP-PIB). The plane was tested in a military aviation school in Dęblin in 1992.

Only a short series of 14 aircraft has been made by now, from which four remainin in Poland. The plane is still offered by the PZL Mielec and is certified in the USA, Australia and Europe (EASA). In the USA it is offered under a name Airwolf or Air Wolf, and 8 were exported there, starting from 1996. In 1998 two were delivered to Venezuelan National Guard. There are works to fit Walter M601 turboprop engine, for eventual customers' demand.
