N599TM

This airframe, registered as N599TM, is a 2004-built Raytheon Beechjet 400A (Nextant 400XTi conversion) with serial number RK-398. The airframe is registered in the United States and is recorded as owned by BRAVO ZULU NEXTANT N599TM LLC, an LLC based in Portage, Michigan; the registration and ownership record indicate corporate operation rather than individual ownership. The subject aircraft was completed in the factory year 2004 and later received the Nextant 400XTi conversion package, an important modification that updated its engines and systems. The registration to BRAVO ZULU NEXTANT N599TM LLC reflects its placement into a corporate/operator fleet based in Portage, MI.

The cabin of this airframe is configured in a typical executive layout accommodating 6–8 passengers in a flat-floor arrangement with options for a left-side galley, although registry certification permits up to 10 seats. As a Nextant 400XTi-converted Beechjet 400A, many examples—including this airframe—are commonly fitted with the Collins Pro Line 21 avionics suite as part of the upgrade package, enhancing situational awareness and systems integration for corporate and charter operations. Operational profiles for this aircraft type and configuration generally include short- to medium-range corporate missions and on-demand charter flights within a 1,500+ nm radius at high cruise speeds, based from its operator’s home in Portage, MI. Maintenance considerations for this specific converted airframe include adherence to the engine upgrade program and modification-traceability for the Nextant conversion.

The Nextant 400XTi conversion positions the Beechjet 400A family into a niche focused on performance improvement and avionics modernization, offering higher efficiency and updated systems compared with earlier stock Beechjet 400A examples. Typical competitors in the light-to-midsize refurbished-cabin segment include remanufactured light jets and newer light-medium jets that emphasize lower operating costs and modern avionics. From a resale and maintenance standpoint, the presence of Williams FJ44-3AP engines and Collins Pro Line 21 avionics on this converted airframe are positive factors for buyer interest, but valuation and marketability remain tied to maintenance records, completion condition, and the documented Nextant conversion status.
