Operational Context

Nextant 400XT — remanufactured light business jet

The 400XT first flew in 2010 and entered service in 2011. It was developed by replacing older engines and installing modern avionics in refurbished Beechjet airframes. The aircraft retains the swept wing and twin rear-mounted engine configuration.

Powered by two Williams FJ44 turbofan engines producing approximately 3,050 pounds of thrust (13.6 kN) each, the 400XT cruises at around 460 knots (852 km/h). Maximum takeoff weight exceeds 16,000 pounds (7,257 kg). The cabin typically seats six to eight passengers.

The 400XT offered improved fuel efficiency compared with the original Beechjet. It demonstrated the viability of remanufactured business jets. Production numbers were limited but influential in the aftermarket sector.
