Design

The 40T was a high-wing monoplane of conventional layout with a thick-sectioned, cantilever wing.[1][3] The flight deck and cargo bay were fully enclosed, and the latter could be adapted to seat five passengers.[3][4] The fixed undercarriage consisted of divided main units with spatted wheels, plus a tailskid. Construction was of metal throughout.[1][2]

The two 40Ts were followed by a single example designated 41T with more powerful Salmson 9Nc engines that first flew on 12 December 1931.[1] Services Aeriens de Madagascar operated the 41T between Tananarive and Broken Hill (where the route connected with Imperial Airways).[2][4]

Eventually, the 40Ts were fitted with this same engine, at which time they were redesignated SPCA 218.[1]
