Hawker 4000 Private jet Charter Hawker 4000 is being certified to FAA FAR Part 25 standards, which places a five-year time limit on certification of a new transport category aircraft. The 4000 completed Function and Reliability Tests on May 25, 2006. During September 2005, a prototype underwent testing at the McKinley Climatic Laboratory at Eglin Air Force Base, Florida.[8] However, since the Part 25 five-year window expired May 31, 2006, the company filed an extension request to head off the possibility that the certification program would need to restart from the beginning. On November 21, 2006, the company announced that the 4000 had received its FAA type certification.

The Hawker 4000, originally known as the Hawker Horizon, is a super-midsize business jet developed by Hawker Beechcraft (formerly Raytheon Aircraft Company). The Hawker 4000 received its certification from the Civil Aviation Administration of China in December 2009. In February 2010, Hawker Beechcraft delivered its first Hawker 4000 to a customer in mainland China. Production of the Hawker 400 began in 2010 and ended in 2013, with less than 180 aircraft being built.
The Hawker 4000 can be outfitted to seat ten people. The aircraft’s carbon composite construction gives it more interior space than many jets in its class. Interior standing room is an average of six feet. This composite construction also makes the aircraft lighter than a standard aluminum structure, allowing a maximum range of 3,445 nautical miles, and a service ceiling of 45,000 feet (14,000 m). The flight deck features a Honeywell Primus Epic avionics suite with EICAS, FADEC and autothrottle.

As of May 2013, Hawker-Beechcraft is offering its jet division, including the Hawker 4000 project, for sale. The company intends to focus on propeller-driven aircraft; leaving the future of the Hawker 4000 up to an eventual buyer.
