G.91Y

The Fiat (later Aeritalia) G.91Y is a ground attack and reconnaissance aircraft designed and originally produced by the Italian aircraft manufacturer Fiat Aviazione. The G.91Y is a derivative of the Fiat G.91; while intended to perform the same roles and baring a strong visual resemblance to one another, the G.91Y was an extensive redesign of its predecessor. The most prominent difference between the two aircraft was that G.91Y was powered by a new twin-engine configuration that replaced the earlier aircraft's single engine arrangement. In combination with weight reduction measures, additional fuel tanks, and a variety of new licence-produced avionics, the G.91Y's performance and capabilities differed considerably from the G.91. Three pre-production G.91Ys were built, one of which performed the type's maiden flight on 27 December 1966. The flight test programme was relatively trouble-free, permitting the G.91Y to enter service with Italian Air Force in July 1968. The service procured multiple batches, it was the sole operator of the G.19Y, although efforts to garner export sales were made, which included the developed of the further improved G.91YS model that underwent a formal evaluation by Switzerland as well as numerous visits to various international airshows. The Italian Air Force withdrew the last of its G.91Ys during 1994, by which time the type been replaced by the newer AMX.
