N501TB

The airframe bearing tail number N501TB is a 1978-built Cessna 501 Citation I/SP, serial 501-0239, currently owned by JONDU SERVICES LLC of Roseville, California, United States. The airframe’s U.S. registration reflects its fixed-wing multi-engine category and an executive configuration recorded at registration as eight seats. Registry records note its continued operation under the private LLC ownership based in Roseville, CA, and the airframe carries an estimated market value of $791,000 consistent with late-1970s light business jet examples in the fleet.

The aircraft is registered with an executive cabin layout of 8 seats, reflecting a typical Citation I/SP interior intended for corporate or owner-operator transport. Its mission profile, given a cruise speed of 322 knots and a range of 1,328 nautical miles, is suited to short- to medium-haul point-to-point business travel and regional trips from its base in Roseville, California. Maintenance and operational considerations for this specific airframe align with older-generation Pratt & Whitney Canada JT15D turbofan powerplants, each producing 2,200 pounds of thrust, and routine inspections consistent with sustained operation of a 1978-built Citation. The U.S. registration and private LLC ownership suggest typical operator-driven maintenance planning and itinerary flexibility rather than dedicated charter scheduling.

As a member of the Citation I/SP family, this airframe occupies the light business jet niche that emphasizes efficient regional performance and simple operating economics for owner-operators. With a certified service ceiling of 41,000 feet and a cruise near 322 knots, the type competes historically with other late-1970s light jets in owner-flown and small-fleet markets. Resale and maintenance considerations for this serial (501-0239) reflect age-related component and avionics upgrades commonly encountered in the model line, factors that contribute to the current estimated value of $791,000 and influence buyer demand in secondary markets.
