N554TT

This entry covers airframe N554TT, a 1979-built Cessna 501 Citation I/SP with serial number 501-0133. The airframe is recorded in the United States registry and is owned by INTERNATIONAL AIR SERVICES INC TRUSTEE, a corporate owner based in Carson City, NV, US. The aircraft is a late-1970s example of the Citation I/SP production run, retaining the original twin-engine JT15D powerplant configuration and eight-seat certification on FAA records. Registered as a U.S. civil transport, its administrative and operational history is tied to the corporate trustee ownership model rather than an individual owner.

FAA records list the cabin configuration for N554TT as 8 seats, while common executive arrangements for the model family typically accommodate 5–7 passengers in a more luxurious layout; this underscores the flexibility between certified seating capacity and operator interior choices. The aircraft’s owner is based in Carson City, NV, US, indicating its administrative operator base and likely region of primary operations under corporate trust ownership. With a cruise speed of 357 kts and a range of 1,328 nm, missions for this specific airframe would typically include short to medium regional executive travel and intra‑continental point‑to‑point charters consistent with Citation I/SP usage. No specific avionics, cabin amenity, or maintenance history items are published for this tail number beyond the certification and seating record.

The Cessna 501 Citation I/SP occupies a performance niche as an early light corporate jet, offering transcontinental capability for its era with a service ceiling up to 41,000 ft. Powered by two Pratt & Whitney Canada JT15D-1 engines producing 2,200 lbf each, the model competes historically with contemporaries in the late‑1970s light jet market for owner‑operators and small corporate flight departments. Buyer and charter demand for specific airframes like N554TT is influenced by condition, avionics upgrades, interior configuration (FAA records versus executive layouts), and continued maintenance considerations typical for vintage airframes of this production period.
