Neiva 360 Regente/420 Lanceiro Series

History

The Neiva Lanceiro is a Brazilian light-plane, but shows marked American influence in its basic design. One unusual feature of the Lanceiro is the sharp taper on both the leading- and trailing-edges of the wingtips.

In 1959 Neiva started work on the design of an all-metal four-seat light aircraft, initially designated Neiva 360C. The prototype flew on 7 September 1961 and the Brazilian Ministry of Aeronautics granted a Type Certificate on 12 November 1963. Powered by a 180-hp (134-k W) Continental 0-360-A1D engine with a Hartzell constant-speed propeller, the aircraft was put into production, as the Regente 360C, against an order for 80 examples from the Brazilian air force. In military service it became the U-42 (later C-42)and the first delivery was made in February 1975.

Neiva also developed for the Brazilian air force a liaison and observation version of the Regente, to replace the Nevia L-6s and Cessna 0-1 Bird Dogs then in service. The rear fuselage was lowered to provide improved all-round visibility from the cabin, which contained three seats, and underwing carriers could be fitted for the attachment of light stores. The prototype Regente 42OL or YL-42, powered by a 210-hp (157-KW) Continental IO-360-D, made its first flight in January 1967 and 40 production L-42s were ordered. The first of these flew in June 1969 and production was terminated in March 1971. During the following year, however, the company flew the prototype of a four-seat civil version which was to become known as the Lanceiro. The first production Lanciero flew on 5 September 1973 and manufacture creased in 1976. The specification applies to the Lanceiro.
