The Hongdu N-5, (N-5 - Nongye-Feiji-5 - agricultural aircraft-5), originally known as the Nanchang N-5, is a Chinese agricultural aircraft. First flown in 1989, and entering into production in 1992, the N-5 is a single-engined low-wing monoplane, and is available in versions powered by a piston engine or a turboprop.

Development and design
editIn November 1987, the Nanchang Aircraft Manufacturing Company (which was renamed the Hongdu Aviation Industry Group in 1998[1]) began design of a modern, purpose designed agricultural aircraft, with the intention of replacing some of the large numbers of license-built Antonov An-2s in use for that purpose in China. The resulting design, the N-5 first flew on 26 December 1989.[2] It is a single-engined monoplane of conventional layout for an agricultural aircraft with a low-wing situated ahead of the cockpit. It is of all-metal construction, except for a glassfibre hopper for chemicals ahead of the cockpit, which is sealed and pressurised to protect the crew during spraying operations, and has an undercarriage. It is flown by a single pilot, with a tandem jump-seat provided to allow a mechanic to be carried. It is powered by a single Lycoming O-720 eight-cylinder piston engine, and was certified as airworthy in this form by the Civil Aviation Administration of China on 12 August 1992.[3][4] The N-5A was certified by the Federal Aviation Administration for use in the United States on 26 February 2007.[5]
In response to demands from Chinese operators for a more powerful aircraft, studies were made of versions powered both by more powerful piston and turboprop engines,[6] before settling on a Czech Walter M601 turboprop to produce the N-5B, this variant replacing the nosewheel undercarriage of the N-5A with a tailwheel undercarriage. The N-5B first flew on 28 December 2006.[7]
