N16NL

This entry covers airframe N16NL, a 1977-built Cessna 501 Citation I/SP with serial number 501-0043. The airframe is owned by WH AIR LLC, a corporation based in Clearwater, FL, US, and is registered in the United States. The twinjet was manufactured by Cessna (Textron Aviation) and is configured in an executive layout; broker and spec listings place an indicative market value at $950,000. Maintenance and valuation notes referenced in listings emphasize the airframe’s age and updated avionics fit as primary factors influencing condition and resale value.

The cabin is arranged as a four-place club with an additional forward right-side aft-facing seat and an aft lavatory in an executive layout, accommodating a total of 8 seats. Reported avionics equipment on this airframe includes dual Garmin GNS-530W, dual Garmin GTX-330ES transponders, Collins ADF-60, Collins DME-40, Sperry SPZ-500 autopilot, Bendix color weather radar, and Garmin GDL-69 traffic/ADS‑B equipment, according to broker/spec listings. Typical mission profiles for this airframe would be short- to medium-range executive transport within its published range of 1,328 nm, with cruise speeds around 350 kts, and operations up to a service ceiling of 41,000 ft. The owner/operator base in Clearwater, Florida supports regional and interstate business flying; maintenance considerations center on legacy JT15D-1 engine support and avionics upkeep consistent with the aircraft’s 1977 build year.

The Cessna 501 Citation I/SP occupies a light twinjet niche offering higher cruise speeds and cabin comfort relative to turboprops but at older-generation systems and engine types compared with later Citation variants. Competing models in the used market include contemporary light jets configured for eight passengers; buyer and charter demand is influenced by total time, avionics upgrades, and aftermarket support for JT15D-1 engines. Resale and maintenance considerations for this airframe emphasize its age, the value uplift from modern avionics like the dual GNS-530W/GTX-330ES fit, and the prevailing market appetite for well-equipped, executive-configured light jets.
