About the Hawker 4000

The Hawker 400XP represents Hawker Beechcraft's turboprop-powered variant of the popular Beechjet 400 light business jet family, originally designed by Mitsubishi Heavy Industries as the MU-300 Diamond in the late 1970s. While most operators know the type as a twin-jet corporate shuttle, the HA4T designation covers turboprop conversions and specialized variants optimized for short-field performance, cargo operations, and utility missions where jet fuel availability or operating economics favor turbine power over pure jets. The type retains the swept T-tail and stand-up cabin of its jet siblings but trades raw speed for improved fuel efficiency and lower operating costs on shorter regional routes.

With a maximum takeoff weight of 12,500 pounds, the HA4T sits at the upper boundary of the FAA's light aircraft category, offering operators a useful blend of cabin comfort, reasonable cruise speeds around 280 knots, and access to shorter runways that larger turboprops cannot serve. The aircraft's approach speed of approximately 100 knots and relatively benign stall characteristics make it manageable for single-pilot operations under appropriate certification, though most commercial operators fly it with two crew. Its operational flexibility has made it popular with cargo haulers, forestry patrol operators, and on-demand charter services operating in the western United States and Alaska, where runway length and fuel logistics often dictate equipment choices.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
