N25MX

This entry covers airframe N25MX, a Dassault Mystère Falcon 900 built in 1999 with serial number 182. The aircraft is manufactured by Dassault Aviation and is registered in the US; its current recorded owner is ACE PARTS LLC, an LLC located in Santa Fe Springs, CA, US. The airframe’s documented configuration and legacy avionics indicate an in-service executive transport role, and the airframe was last appraised at $9,300,000. Ownership consolidation under ACE PARTS LLC and the US registration represent the most notable recent registry details available for this airframe.

The cabin of N25MX is fitted in an executive 10–12 passenger layout featuring a forward galley, forward crew lavatory and aft lavatory, supporting typical corporate and charter missions that prioritize passenger comfort on mid- to long-range sectors. Avionics are a mixed legacy fit of Collins and Honeywell components, with specific equipment reported including Collins DME-442, Collins ADF-462 and Honeywell Primus-class elements, which suggests phased upgrade potential and considerations for avionics retrofit programs. With three Honeywell TFE731 engines producing 4,750 lbf each, this airframe is operated from its owner’s base in Santa Fe Springs, CA, for missions that commonly exploit the type’s transcontinental and international range capability. Maintenance and logistical planning for this specific aircraft will need to account for legacy avionics support and parts sourcing tied to its mixed Collins/Honeywell suite.

As a member of the Falcon 900 family, Dassault Mystère Falcon 900 airframe N25MX occupies the midsize-to-large tri-jet executive transport niche, offering long-range capability and high-altitude performance to 51,000 ft. Competing types in its segment include other long-range business jets and early-generation large-cabin twins; buyers and charter operators often balance acquisition price, maintenance history and avionics modernization needs when valuing examples like this one. The reported valuation of $9,300,000 reflects age, configuration and the costs associated with legacy avionics and tri-engine maintenance considerations for resale or continued commercial operation.
