Development
To meet an Italian Army requirement for a short take-off liaison aircraft, SIAI-Marchetti modified the design of the Cessna 305A/O-1 Bird Dog with a new turboprop engine and a revised tail unit. The prototype first flew on 24 May 1969 powered by a 317 hp (236 kW) Allison 250-B15C turboprop engine. It was evaluated against the Aermacchi AM.3 and was successful and won a production order for 80 aircraft.
