Jetstream 41 G-JMAC

A cancelled contract for the United States Air Force and subsequent cost overruns led to the demise of the company in 1969 and the aircraft was eventually manufactured by Scottish Aviation Ltd which was itself absorbed into British Aerospace Scottish Division in 1978. An uprated Astazou was fitted into the new version, the Jetstream 200, and this was selected by the Royal Air Force (Jetstream T.1) and Royal Navy (Jetstream T.2) as well as several civilian operators.

In 1980, the Jetstream 31 arrived, powered by Garrett TPE331-10 engines. A further update of the TPE331 led to the Jetstream 32 and these two variants proved to be very successful with sales of 386 aircraft before production ceased in 1993.
At the Paris Air Show in 1989, BAe displayed a mock-up of a larger advanced version to be called the Jetstream 41. It had a longer fuselage, increased wing span, larger tail plane area, modernisation of the flightdeck instrumentation and more powerful TPE331-14 engines enabling it to carry up to 29 passengers. The prototype Jetstream 41 first flew on 25th September 1991.

G-JMAC is the fourth prototype and was first flown on the 8th July 1992. Originally registered G-AMC after Alan MacDonald, the managing director of British Aerospace Prestwick, it was also allocated G-JXLI although this was never taken up. G-JMAC was used as a company demonstrator, pilot trainer and test aircraft. G-JMAC completed a successful tour of Austrailasia, took part in cabin noise reduction trials and steep approach trials into London City Airport. It last flew in the year 2000 having aquired less than 900 hourd flight time on the airframe.

If you watch closely you may spot her in the BBC thriller "The City & The City" starring our very own David Morrissey.

A total of 104 airframes (including the 3 prototypes) were completed before production ended in 1997.

The original design can be traced back as far as the 1960s when Handley Page produced a design for a 12-20 seat, twin turboprop aircraft known as the H.P.137 Jetstream. The first flight was on 18th August 1967. The Turbomeca Astazou XIV turboprop engine was selected but proved underpowered and temperamental resulting in a poor range.
