The SAM-5 was a cantilever high-wing monoplane with fixed conventional landing gear and an enclosed cabin for a pilot and four passengers.^[1] The first prototype was built using stressed-skin light alloy construction but it had problems with the quality of workmanship in what was an unfamiliar material.^[1] The second-prototype SAM-5bis was built using plywood and fabric and had wing bracing and a more slender fuselage.^[1] After testing 37 production aircraft were built and they were delivered from 1937 as air ambulances with room for three patients and an attendant.^[1]

Moskalyev then worked on an improved variant, the SAM-5-2bis, tested with a 200 hp (149 kW) engine; the aircraft established distance and height records.^[1] An order was placed for 200 of the improved variant, again for use as an air ambulance but they were never built.^[1] This last SAM-5 variant led to four, differently numbered, developments.
