The SIAI-Marchetti SM.1019 is an Italian STOL liaison monoplane built by SIAI-Marchetti for the Italian Army. It is a turboprop-powered derivative of the Cessna O-1 Bird Dog.
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.
On 24 July 2021, former US Navy F-14 pilot Dale "Snort" Snodgrass fatally crashed in an SM.1019B with the registration N28U at LewistonâÂÂNez Perce County Airport in Lewiston, Idaho. The probable cause of the accident was, according to the NTSB report, failure to remove the flight control lock, which immobilized flight control surfaces.
