De Havilland DH.125 / Hawker Siddeley HS.125 / BAe 125

In 1961, de Havilland began working on a revolutionary small business jet known as DH.125 Jet Dragon. The first of two prototypes flew on 13 August 1962 with Rolls-Royce Viper 20 engines producing 1350kg of thrust each. The first production aircraft had a 0.9m greater wingspan and 1.2m longer fuselage as well as Viper 520 engines.

The aircraft went through many designation changes during its service life. Originally DH.125, it was renamed to HS.125 when de Havilland became a part of the Hawker-Siddeley group. When Hawker-Siddeley itself merged into British Aerospace in 1977, the name was changed to BAe 125. Then, when British Aerospace sold its Business Jets Division to Raytheon in 1993, the jet acquired its current monicker Raytheon Hawker. In 1996, production was transferred to United States.

Over 1,000 aircraft have been built.

My brother recently purchased a decommissioned 72 HS 125-400A originally British Airways /Hawker Siddelley. We have been crawling around the innards trying to locate the battery compartment. Does anyone have any suggestions on where to find manuals or imagery of its location?

I flew, trained others, and supervised mx on every variant of this aircraft… One of my very FAvorites! Especially fond of the Viper-powered airframes…but ALL of them Sturdy, sweet-handling, predictable. A close friendship with HS Tech-Rep Maurice Helmore was a highlight of association with this airplane. Saddened by its’ end-of-production.

As an ex-employee of de Havilland, I would suggest that there needs to be severe pruning of the entries here as quite clearly they have nothing to do with the DH 125 !

I contracted GHSV2 in2006 and up until 2009 only had 4-6 OBs a year. But since the beginning of 2009 was experiencing more frequent OBs at least once a month! I thought the general rule was that OBs become LESS frequent with time and not MORE! It just got to the point where I couldn't handle it anymore. I went online and found your site pretty quickly. It didn't take long between the time I whipped out my CC to the time I started putting your method to work. It is the best decision I ever made. I went from having OBs every couple weeks at worst, to not having an outbreak for 3 months now. I know this isn't just a coincidence and your method is responsible for giving me my life back thank you so much Doctor

Myself and others built the tail plane, main fin, rudder and Over fin for this aircraft . I miss building those parts, I learnt a lot from this aircraft ;).

I flew this basic model back in 1967-1970 for Anglo American Corp. (Mines Air Services) in Zambia. A very easy aircraft to fly. I met John Cunningham at Luton UK on a trip there in 1969 while flying this aircraft.

I flew the F400, 600, 700, and 800 during my career. there was another designation, BH125-400. These aircraft were brought to the US in "green" configuration, and completed by Beech. Our first F400 actually had a Beechcraft placard! The "real" first Beechjet! Great airplanes. The 800 was truly a magnificent flying machine.
