The CANT Z.509 was a three-engine Italianfloatplane developed from the Z.506A for use as a mailplane.
Design and development
Designed as a larger and heavier version of the Z.506A, three aircraft were built in 1937 for Ala Littoria. The aircraft were for use on the airline's transatlantic postal service to South America. The aircraft was a twin-float seaplane powered by three Fiat A.80 R.C.41radial engines.
With the outbreak of World War II, development of the type was abandoned.
