Nardi FN.333 Riviera

The Italian Riviera amphibian was originally designed and flight-tested by Nardi S.A. per Costruzioni Aeronautiche under the designation FN.333.

The Nardi concern was established by the four Nardi brothers in Milan in 1933.  Their first product, the FN.305, first flew in 1935.  The Nardi factory at Loreto was almost completely destroyed  during WW2.  After the war, their new factory was built at Aeroporto Forlanini, Milan.  In addition to aircraft manufacture, the company also specialized in production of wheels, brakes, retractable landing gears, hydraulic and electric aircraft controls, fuel pumps, armament installations and aircraft accessories generally.

Nardi's first post war aircraft was the FN.333 all-metal three seat amphibian.  The first prototype FN.333, I-KISS, made its maiden flight on 4 December 1952, powered by a 145 hp Continental fan-cooled engine.  The production development model FN.333-S was planned to have four seat, a 225 hp Continental C125 engine and have folding wings.  The outer sections of the wings were to fold in two halves, one section folding upwards and the other folding downwards with the wing tip floats, to give stability on water.

This idea was, however, never carried out.  However, the second Nardi built prototype did have a more powerful engine and a fourth seat, and made its first flight on 8 December 1954.  The development of the FN.333 was very slow at Nardi, and the third Nardi-built aircraft did not fly until 14 October 1956, this time with a 240 hp Continental O-470-H engine.

In March 1959  SIAI Marchetti acquired the manufacturing rights from Nardi.  At their  plant in Sesto Calende, Varese near Milano (Italy) SIAI Marchetti started the manufacture of a first series of 10 Rivieras.  The first SIAI Marchetti manufactured Riviera was rolled out in February 1962, and by January 1963 four aircraft had been delivered to customers.  The production version now had a 250 hp Continental IO-470-P engine, with fuel injection.


When the Riviera was placed on the American market in 1961 by Lane-SIAI Company of Dallas, ServAir Inc. of Detroit became the dealer for the Riviera in the Michigan area.  ServAir was a company owned by Mr. George H. Paquette.  ServAir received the first production model on 13 July 1962, when it arrived aboard ship at Newark, New York, complete and ready to fly.

The majority of the production Rivieras were sold to the USA, where Southwest Airmotive received the aircraft for assembly before delivery to their US owners.  North Star Company, Newark, NJ, was marketing the Rivieras in America.

In 1960 an Italian-piloted Riviera set 6 FAI altitude and speed records for her class of flying boats and amphibians.  A pure flying boat version, designated FN.333 W, was projected but never built.
