BEECHCRAFT BEECHJET SERIES

Beechcraft BeechJet 400 Series Jets for Sale — The Mitsubishi-Beech Light Jet

The Beechcraft BeechJet 400 series tells a story that spans continents and corporate histories — a Japanese-designed business jet that became an American icon under Beechcraft's stewardship and ultimately served as the foundation for one of Raytheon's most successful light jet programs. The design originated as the Mitsubishi Diamond I, introduced in 1977 as Japan's first domestically designed business jet. Beech Aircraft acquired the type certificate in 1985, redesignating the aircraft as the BeechJet 400 and launching a production program that would eventually produce over 800 examples under the Beech, Raytheon, and Hawker Beechcraft brands — one of the most successful light jet programs in aviation history.

BeechJet 400 vs 400A — The Key Differences

The BeechJet 400 and 400A are meaningfully different aircraft despite their visual similarity. The original 400 used Pratt & Whitney Canada JT15D-4D engines producing 2,900 lbf thrust each. The 400A — which became the dominant production variant and the basis for the military T-1A Jayhawk trainer — upgraded to JT15D-5 engines at 2,965 lbf with improved reliability and Parts availability, added a Collins Pro Line 4 EFIS cockpit, and incorporated numerous airframe and systems refinements. The 400A's Pro Line 4 avionics represent a significant situational awareness advantage over the 400's earlier electromechanical instrumentation.

Performance Characteristics

The BeechJet 400A cruises at up to 450 knots at optimal altitude with a range of approximately 1,600 nautical miles in NBAA IFR conditions — figures that made it genuinely competitive in the light jet market during its production years and that continue to make it a practical aircraft for regional business travel. Maximum operating altitude of 45,000 feet allows the BeechJet to fly above the weather that plagues lower-altitude aircraft, and the pressurized cabin maintains comfortable altitudes at cruise. The side-facing club seating arrangement for typically seven passengers provides a genuinely usable cabin for business travel.
