Technical description. Float-type seaplane for transport and passenger transatlantic flights, was a four-engine low-wing aircraft of all-metal construction.
The wing is one-spar, trapezoidal, consisting of 5 parts (center section with engines, cantilevers and wingtips) and a working duralumin wing skin. Ailerons and flaps are all-metal. Passages in the leading edge of the wing were intended to control the operation of engines and fuel tanks. The tail unit had a duralumin structure and plating, with the exception of the elevator and rudder, covered with canvas. The floats were of a metal structure and covered with duralumin sheathing and connected to the fuselage using an orderly structure of steel pipes: inside there was a stepladder for communication between the float and the wing tunnel. Elliptical fuselage with duralumin construction.
Engines with metal three-bladed propellers of variable pitch - Piaggio P.1002 and constant speed with electrical control and display systems. The fuel was placed in the wing tanks (additionally in the fuselage - 1335 liters), the maximum tank capacity - 16340 liters (11930 kg).
A cockpit with side-by-side dual controls, a dashboard with instruments for flight and navigation equipment and engine control. The aircraft was fitted with the Salmoiraghi autopilot; behind the pilots' seats were the work stations of the flight mechanic and radio operator with communication radio equipment.
The passenger compartment was not installed on the prototype, but was calculated for 16 passenger seats with folding berths equipped with individual lighting, ventilation and heating in 4 compartments (transatlantic configuration) or for 48 seats, equipped in 4 compartments of 12 places in each. In front of the passenger compartment there was a toilet and a kitchen, behind - a toilet and a lobby. The lower cargo compartment was located along the entire length of the passenger compartment and was accessible in flight: for this it was possible to pass through the passages in the leading edge of the wing.
