N307MR

The airframe bearing tail number N307MR is a 1977-built Cessna 501 Citation SP Eagle II, serial number 501-0012, recorded on the U.S. registry. The airframe is owned by SILVERSTAR II LLC, an LLC based in Houston, TX, US, which currently appears as the registered owner and operator for corporate or private executive use. Maintenance and registry entries for this specific airframe have been handled under the United States registration US, and no public valuation summary is published for this airframe. The most notable documented change in this aircraft’s custodial history is its registration to SILVERSTAR II LLC in Houston, which marks its current operational base and primary administrative contact.

The cabin on this airframe is configured in an executive layout with 8-seat accommodation typical for Citation 501 variants, supporting corporate shuttle, owner-flown, or on-demand charter missions within its range profile. Avionics fit is consistent with upgraded Citation 501 platforms that have undergone modern powerplant conversions, supporting instrument flight rules operations into medium-length routes up to its listed 1,328 nm range and cruise at 357 kts. Based in Houston under its registered owner, the aircraft is optimized for high-utilization regional point-to-point missions and business travel, operating routinely at typical Citation altitudes up to 41,000 ft. Maintenance considerations specific to this airframe include attention to the Sierra FJ-44 conversion program elements and associated integration of systems with the original airframe.

The Cessna 501 Citation SP Eagle II occupies a light-to-mid-size turbofan business jet niche, offering higher cruise speeds and altitudes than many piston or turboprop transports of similar era. With a converted powerplant package such as the Williams FJ44 series, owners seek improved fuel efficiency and performance compared with original installations, making this airframe attractive for operators prioritizing speed and climb performance. Competing models include other light jets and early medium light-cabins targeting corporate shuttles; buyer and charter demand generally emphasizes upgrade history, avionics modernization, and documented maintenance on conversions when assessing resale or continued operation.
