Apart from the three engines and a consequent increase in weight and slight reduction in length, the D.31 was very similar to the D.30. It first flew on 12 January 1932, initially powered by the 172 kW (230 hp) 9Qa engine variant. In 1935 these were replaced by 240 kW (320 hp) 9Qbs. In this form the outer engines remained uncowled but the central one had a long
