BH.125-400A

The BH.125‑400A is a midsize business jet that traces its origins to the 1960s Hawker Siddeley HS‑125 program. In 2006 the type was transferred to Beechcraft, which marketed it under the BH.125 designation while retaining the proven airframe and systems. The 400A model entered service in 2009 and represents the final major upgrade of the original line before production ceased in 2013. Powered by two Honeywell TFE‑731‑40R‑2 turbofan engines, the jet delivers 4 500 lb of thrust each, enabling a cruising speed of Mach 0.78 and a range of roughly 2 250 nautical miles with four passengers. The cabin, pressurised to 8,000 ft, offers a spacious, low‑noise environment with a flat floor and flexible seating configurations that appeal to corporate, medical‑evacuation, and government operators. Advanced avionics, including a Rockwell Collins Pro Line 21 flight deck, provide full‑color displays, synthetic‑vision and modern autopilot capabilities. The BH.125‑400A’s significance lies in its demonstration that a design launched in the 1960s could be continuously refined to meet contemporary standards, offering a cost‑effective alternative to newer jets while preserving the reliability and support network that have made the HS‑125 family a mainstay in business aviation for over five decades.
