The Partenavia P.57 Fachiro is an Italian, four-seat, high-wing, touring monoplane, fitted with a fixed tricycle undercarriage.

A later version, designated the II-f, introduced a swept fin and rudder.

The Fachiro utilises mixed steel tube-and-fabric construction and is fitted with a 160 hp (119 kW) engine for aero club and general aviation use.

[2] A one-off, all-metal version, the P.64 Fachiro III, was further developed as the P.64 Oscar.

Seven examples of the Fachiro IIf version remained in operation within Italy during spring 2009.
