The successful Jetstream 31 originated from the Turboméca Astazou powered Handley Page HP-137 Jetstream 1 which first flew in 1967. Initial Handley Page production aircraft were delayed by excess weight and drag problems. To overcome these problems Handley Page developed the Jetstream 2 with more powerful 1073shp (800kW) Astazou XIVCs. However Handley Page ran into serious financial difficulties in the late 1960s and it folded in 1969. Development of the Jetstream 2 resumed in 1970 as the Jetstream 200 under the control of the newly formed Jetstream Aircraft in collaboration with Scottish Aviation. Scottish Aviation later assumed overall responsibility for the Jetstream and built a number as navigation and multi-engine trainers for Britain's military services as the Jetstream T1 and T2. Development continued after Scottish Aviation was merged into British Aerospace in 1977, and work on the Jetstream 31 (or J31) began in 1978, which was refitted with the Garrett TPE331 in 1980. The first production aircraft flew in March 1982.. In British Naval service the J31 is designated the Jetstream T3.
Subsequent development led to the Super 31, certificated in October 1988. The Super 31 (or unofficially J32) features uprated engines, higher weights and better performance. The last J31/J32 was built in 1993. The upgraded J32EP (Enhanced Performance) offers minor aerodynamic and drag improvements enhance payload range and hot and high performance. |
