N789MJ

This entry covers airframe N789MJ, a 2008-built Cessna business jet registered in the United States with serial number 680-0205. The airframe is owned by Eagle Union Quest One LLC (an LLC) and is based in Philadelphia, PA, US, reflecting a corporate ownership profile rather than individual ownership. No additional operator changes or notable registry actions are published beyond this ownership record. The listed market valuation for this specific airframe is $6,450,000, which is consistent with a well-equipped late-2000s Citation Sovereign in active service.

The cabin of N789MJ is fitted in a nine-passenger layout featuring two four‑place club groups and one right‑hand side‑facing seat, complemented by a forward galley and an enclosed lavatory, supporting typical corporate mission profiles of short‑to‑mid‑international range executive transport. Avionics are a Honeywell Primus Epic (EPIC 5.3) suite with dual FMS, TCAS II Change 7.1 and ADS‑B out, providing modern navigation, traffic awareness and mandated surveillance capability for continental and oceanic operations. With a cruise speed of 459 kts and a maximum operating ceiling of 47,000 ft, the airframe is suited to point‑to‑point transcontinental missions and frequent business shuttle rotations from its Philadelphia base. Maintenance considerations for this individual aircraft will align with operator practices for PW306C‑powered Sovereigns, including engine and avionics life‑cycle management consistent with corporate ownership.

The Cessna 680 Citation Sovereign occupies a performance niche between light and super‑midsize business jets, offering transcontinental range and elevated cruise speed suitable for high‑utilization corporate operators. Competing models typically include other super‑midsize types offering similar range and cabin comfort; buyer and charter demand remains oriented toward examples with modern avionics and well‑documented maintenance histories such as this airframe. Resale and maintenance considerations emphasize engine time on the Pratt & Whitney Canada PW306C pair, avionics currency (EPIC 5.3, TCAS Change 7.1, ADS‑B out), and the completeness of the aircraft’s records to support the $6,450,000 valuation in secondary markets.
