Description
The SIAI-Marchetti SM.1019 is an Italian short take-off and landing (STOL) liaison monoplane built for the Italian Army. Developed to meet an army requirement for a STOL liaison aircraft, the design is a turboprop-powered derivative of the Cessna 305A/O-1 Bird Dog. SIAI-Marchetti modified the Cessna design by integrating a new turboprop engine and a revised tail unit. The prototype completed its first flight on 24 May 1969, powered by a 317 hp (236 kW) Allison 250-B15C turboprop engine. Following evaluations against the Aermacchi AM.3, the SM.1019 was selected for production, securing an order for 80 aircraft.
The aircraft features a high-wing configuration with a NACA 2412 airfoil, a wingspan of 10.972 m, a length of 8.52 m, and a wing area of 16.16 m². It is equipped with a three-bladed Hartzell constant-speed reversible-pitch metal propeller. Fuel is housed in four wing tanks with a total capacity of 320 liters. Performance specifications for the SM.1019A include a maximum cruise speed of 300 km/h at an altitude of 2,500 m, a service ceiling of 7,620 m, and a range of 1,090 km. The aircraft's STOL performance allows for a take-off run of 112 m and a landing run of 91.5 m.
The Italian Army operated the aircraft and designated the SM.1019B variant as the SM.1019E.I. The Somali Air Force acted as an export customer, acquiring six aircraft in 1981, which have since been retired. In civilian service, an SM.1019B registered as N28U crashed on 24 July 2021 at Lewiston–Nez Perce County Airport, Idaho, resulting in the death of pilot Dale Snodgrass. The National Transportation Safety Board attributed the accident to a failure to remove the flight control lock prior to flight.
