N525MX

This entry covers airframe N525MX, a 2001-built Cessna 525 (Citation CJ1) with manufacturer serial 525-0423. The aircraft is registered in the US and is held by _AIRCRAFT GUARANTY CORP TRUSTEE_ of Oklahoma City, OK, US, which appears as the corporate owner on current records. There are no additional operator entries provided; the listed corporate location suggests an Oklahoma City base of record for registry and maintenance oversight. Valuation notes indicate a market worth of $1,900,000, reflecting typical aging fleet considerations for early-2000s light jets.

The interior of N525MX conforms to the Citation CJ1 executive profile with an executive club / forward refreshment layout commonly fitted for 5–8 passengers and includes a small aft baggage compartment. Original avionics fit is the Collins Pro Line 21 suite, with an available Garmin all‑Garmin retrofit STC as a common aftermarket modernization path for owners seeking updated situational awareness and support for modern airspace. With a cruise of 381 kts and a range of 1,266 nm the airframe is typically employed on short to mid‑range business missions, point‑to‑point charters, and corporate repositioning flights. Maintenance planning for this airframe would weigh engine life‑limits and avionics upgrade costs against the stated market value.

The Cessna 525 (Citation CJ1) occupies the light business jet niche, offering single‑pilot capability, compact cabin ergonomics and efficiency for missions under roughly 1,300 nm. In resale and charter markets, examples from the early 2000s are marketed against newer light jets where avionics and interior condition strongly influence demand; the availability of a Garmin retrofit STC is a notable factor in sustaining operational relevance. Buyers and operators typically evaluate ongoing engine shop visit schedules, avionics modernization cost, and the airframe’s established performance envelope—381 kts cruise and 41,000 ft ceiling—when assessing lifecycle and resale value.
