Design and development

edit

The Sparrow Hawk is a twin boom, twin fin, ultralight aircraft built with mixed construction materials most notably including Kevlar, carbon fiber and polyurethane foam.[5][6] It uses a Rotax 532 two-stroke aircraft engine in pusher configuration.[7] It employs a cantilever, shoulder wing, fixed landing gear and a two-seat enclosed cockpit.[2]

In 2022, Sparrow Hawk Aviation Ltd announced that they had plans to redesign and improve the Sparrow Hawk, though no redesigns have been made to the aircraft design yet.[8]

Operational history

edit

The Sparrow Hawk had its official public debut in July 1985 at the EAA Annual Convention and Fly-In, as two Sparrow Hawks, registered as N5793F and N5832M, attended.[6] The manufacturer and model of N5793F is recorded by the Federal Aviation Administration (FAA) as an "Ultralight Aircraft Ltd Sparrow Hawk Mk II",[9] while N5832M is recorded as an "Aero Dynamics Ltd Sparrow Hawk MkII".[10]

A Sparrow Hawk (registered N8728A) was displayed at the Air Display and Air Races event at Cranfield Aerodrome in the United Kingdom, on 20 September 1987.[11][12] The same aircraft was exhibited at the SBAC-organized Farnborough Airshow in September 1988.[13]
