The CNA Eta was a single engine Italian light aircraft, flown in the mid-1930s, that set one and two seat world records as both a landplane and a seaplane.
During the 1920s the Compagnia Nazionale Aeronautica (CNA) were best known for their flying school in Rome, though they also manufactured experimental aircraft for the government.
[2] A 130 kW (170 hp) CNA C-7 engine had enabled a Fiat AS.1 to gain the Category I altitude record in December 1932 and on 6 November 1933 the single seat Eta, with the same motor and fitted with floats, set a new C.II record of 8,411 m (27.595 ft).
It was then fitted with its wheeled undercarriage and flown to a new C.II landplane record of 10,008 m (32,835 ft) in December 1933.
[3] By 1936 the Eta was flying as a two-seat seaplane, powered by the in-line, 112 kW (150 hp) CNA C-VI engine and on 15 May it set a new world C.I 100 km (62 mi) circuit speed record of 192.62 km/h (119.7 mph), flown by Gian Giacomo Chiesi with Domenico Rossetti.
