The design was submitted to the Romanian Air Force for consideration, and elicited sufficient interest to result in an order for two prototypes to be placed.

After nearly a year, an order for 10 aircraft was placed, which were delivered to the air force's pilot training school at Tecuci.

Apart from these standard production models, a number of "one-off" aircraft were developed, including the 41 and 41S - a night-flying trainer and a combat-trainer respectively.

Ionel Ghica flew the special 31G named Foisor on a long-distance flight from Bucharest to Saigon between 30 March and 16 April 1932, covering 9,350 km (5,810 mi) in 2 days, 14 hours, and 25 minutes.

In another feat, Locotenent-comandor Gheorghe Banciulescu, who had two wooden legs, flew the 41R on a 9,000 km (5,600 mi) tour of 15 European countries over nine days.
