PZL M-4 Tarpan
PZL Mielec · Poland · first flew 1961 · light aircraft
The PZL M-4 Tarpan was a Polish two-seat tandem trainer and sports prototype, built to give Aero Club pilots a low-wing aircraft with retractable undercarriage. It never entered production.
Recognition (WEFT)
| W — Wings | Low-mounted, tapered |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | Two tandem cockpits under a single long framed canopy on a slim all-metal fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Fully retractable tricycle undercarriage — almost unheard of on an early-1960s Eastern-bloc light trainer
- Two tandem cockpits under a single long framed canopy on a slim all-metal fuselage
- Very short span, 8.85 m over a 7.35 m fuselage, giving stubby, fighter-like proportions
The close comparator is the Zlin Z-226 Trener, also an all-metal tandem low-wing trainer: the Zlin sits on fixed tailwheel gear with spatted mainwheels and spans 10.3 m, while the Tarpan is a nosewheel aircraft that retracts everything and spans under 9 m.
Specifications
- The PZL M-4 Tarpan has a length of 7.35 m (24 ft).
- It has a wingspan of 8.85 m (29 ft).
- Its maximum speed is 300 km/h (186 mph).
- Typical crew: 2 (tandem, dual controls).

History
WSK-Mielec began design in the late 1950s to an Aero Club of Poland requirement for a tandem low-wing trainer with retractable gear, specifically so club pilots could work up to the Lim-2, which the fixed-gear PZL M-2 could not prepare them for. Stanislaw Jachyra led the project; SP-PAW first flew on 7 September 1961, 142 kg heavier than calculated, and a second prototype SP-PAK followed in July 1964.
Variants
Both prototypes were reworked in 1965 as single-seat aerobatic machines under the designation M-4A; test pilots reported well of them but they saw little use.
Where you'll see it
None. Handling, stability and visibility were all judged good, but the Aero Club withdrew its order in 1963 over price and the unreliability of the Narkiewicz WN-6 engine, and the engine programme was itself cancelled. SP-PAK survives at the Polish Aviation Museum in Krakow.
