Jetstream AIRCRAFT is working on a fresh round of improvements for its J41, aimed at increasing hot and high performance for airfields in countries with developing infrastructures.

From 1996 the aircraft will be offered with a 2.2% increase in engine power, revised stall speeds and the introduction of a 9¡ landing-flap setting. The aim is to bring significant improvements in landing and take-off weight.

Marketing director Nick Godwin says that competition for the South African regional SA Airlink order helped to focus Jetstream on the enhancements, eventually winning the deal for nine J41s in December. The flap-setting and stall-speed improvements are being flown on a test aircraft in South Africa.

A water methanol system and 35° landing flap setting will also be offered as optional extras to improve J41 performance in extreme hot and high conditions.
