Hongdu N-5

N-5

National origin: Peoples Republic of China
Manufacturer: Hongdu Aviation Industry Group
First flight: 26 December 1989
Introduced: 1992

The Hongdu N-5 (originally known as the Nanchang N-5) is a Chinese agricultural aircraft. First flown in 1982, 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

In November 1987, the Nanchang Aircraft Manufacturing Company (which was renamed the Hongdu Aviation Industry Group in 1998) 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 (Nongye-Feiji 5) first flew on 26 December 1989. 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 a 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. The N-5A was certified by the Federal Aviation Administration for use in the United States on 26 February 2007.

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, 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.

Variants

N-5A Main production version, with nosewheel undercarriage and 298 kW (400 hp) Lycoming IO-720 piston engine. N-5B Version powered by 580 kW (777 hp) Walter M601F turboprop engine. Tailwheel undercarriage.
