The Nardi FN.333 Riviera, later the SIAI-Marchetti FN.333 Riviera, is an Italian
luxury touring amphibian flying boat designed and developed by Fratelli Nardi in
the 1950s and produced in small numbers by Savoia-Marchetti during the following
decade.
The FN.333 Riviera was originally developed by the Nardi Company at Aeroporto
Forlanini, Milan, Italy. The first prototype Riviera was registered I-KISS, and
was a three-seat aircraft. This plane made its maiden flight on 4 December 1952,
and was to be the only FN.333 powered by a 145 hp Continental fan-cooled engine.
Beginning with the second prototype a more powerful engine was used, as well as
the addition of a fourth seat. The second prototype made its first flight on 8
December 1954. The Nardi Company lacked the resources to fully develop the
Riviera, and as a result the third aircraft did not fly until 14 October 1956.
Improved power for this aircraft was provided by a 240 hp Continental O-470-H
engine. This aircraft was designated the FN.333S and was to be the basis for
series production. Lacking further resources, Nardi sold the manufacturing
rights for the Riviera to the much larger SIAI-Marchetti in March 1959.
This deal resulted in the first series of 10 production Rivieras being
manufactured at the SIAI-Marchetti factory in Sesto Calende, Varese near Milano,
Italy. The first S.I.A.I.-Marchetti manufactured Riviera was completed in
February 1962, and by January 1963 the company had delivered four of the
aircraft to customers in the USA. The SIAI-Marchetti version had improved power
provided by a 250 hp Continental IO-470-P engine, equipped with fuel injection,
and manufactured for a pusher-style aircraft. In 1961 the Riviera became
available in the United States, where it was initially sold through the North
Star Company of Newark, New Jersey. ServAir Inc. of Detroit sold the Riviera in
Detroit, Michigan, and received its first Riviera on 13 July 1962. This
aircraft, already complete and ready to fly, was placed in the cargo hold of a
ship and transported directly from Italy, arriving in Newark, New Jersey.
Excluding this example, most Rivieras were shipped partially assembled, and were
then completed at Southwest Airmotive before delivery to their owners. Most of
the 26 built by SIAI-Marchetti were sold to customers in the United States, but
examples were also sold to Australia, Norway and Sweden. A pure flying boat
version, lacking landing gear and designated FN.333W, was planned but never
built.

The Riviera is a unique, though not unattractive design, somewhat similar to the
famous Republic Seabee of the 1940s. The major difference between the Riviera
and the Seabee is the use of a high twin-boom tail arrangement on the Riviera
while the Seabee uses a single conventional tail. The Riviera uses a tricycle
landing gear, with the nose gear retracting into the nose and concealed behind
two small nose gear doors. As a result, forward visibility is somewhat better in
the Riviera than in the Seabee when taxiing or taking off on land.
The Riviera is powered by a 250 horsepower (186 kW) Continental IO-470-P
six-cylinder flat engine mounted above the fuselage in a pusher arrangement. A
three-bladed propeller was standard.
