The passenger compartment seated four, each with their own window, and was accessed through a starboard side door. There was a compartment for luggage or mail in the nose.[
The Nu.D.38 was powered by two 160 hp (120 kW) Bramo Sh 14-A4 radial engines, mounted to the main wing spar on steel frames. It had a fixed, conventional undercarriage. A main shock absorber leg was attached to each of the steel engine frames, braced rearwards by a short auxiliary strut. Legs and wheels were enclosed in fairings.][
