N174CF

This entry covers airframe N174CF, a factory Cessna-built jet completed in 1979 as serial 501-0142, later modified to a Sierra Eagle II standard. The airframe is identified as a Cessna 501 Citation I/SP (Sierra Eagle II conversion) and is registered in the United States to TRI STAR SERVICES LLC, an LLC based in Nashville, TN, US. The airframe retains its original serial identification while carrying a notable Sierra Eagle II conversion and repower that replaced the original engines as reflected in advertised listings. Registry activity of record centers on continued civilian ownership and operation from its Nashville operator; valuation and condition are described in sales/advertisement materials primarily through equipment and conversion highlights rather than formal appraisal details.

The cabin on this specific aircraft is outfitted in a seven-passenger executive layout with forward club seating arranged around two executive tables and a three-place aft divan, as advertised. Avionics fit for this airframe includes dual Garmin GTN-750Xi units, dual Garmin GTX-345/335 transponders, a Sperry SPZ-500 autopilot/flight director, Honeywell KGP-560 EGPWS/TAWS, Bendix/King RDR-2000VP weather radar, WSI AV-300 datalink, and an IS&S RVSM system as listed. Based at and operated from the owner’s Nashville, Tennessee base, the aircraft’s 1,600 nm range and 365 kt cruise speed position it for regional executive transport missions; maintenance considerations specific to this airframe include systems and airframe integration associated with the Sierra Eagle II conversion and the repower to Williams FJ44-2A engines.

This airframe represents a converted member of the Citation I/SP lineage tailored to a light business jet mission profile through the Sierra Eagle II repower and avionics upgrades. The conversion and modern avionics installation aim to improve performance, range and regulatory capability (RVSM) relative to the original certification package for the type. For buyers and operators, notable market and maintenance considerations for this airframe include the implications of a non-original engine conversion, the updated avionics suite, and continued adherence to RVSM and equipment-level maintenance practices as advertised.
