N39HH

This airframe, registered as N39HH, is a 1979-built Cessna 501 Citation SP with serial number 501-0132. The airframe is recorded as owned by DIG N WINGS LLC, a corporation based in Knoxville, TN, US, and operates on a United States civil registration. The aircraft’s operational history for this specific tail number centers on corporate ownership and operation from its documented home base in Knoxville; no other ownership changes are published in the supplied data. Registry status is US-based and the airframe’s age (built 1979) is a defining attribute for condition and market considerations.

The cabin of this Citation SP is noted as a typical executive layout configured for 5–8 passengers, with executive club and forward refreshment options reported for type variants, consistent with its use in corporate transport. Powered by twin Pratt & Whitney Canada JT15D-1 turbofan engines, the aircraft is capable of regional point-to-point missions within its 1,328 nm range at a cruise of 352 kts, making it suitable for business trips originating from Knoxville and similar operating bases. Maintenance considerations for this specific airframe include the upkeep typical of late-1970s-model jets—particularly attention to aging systems and engine lifecycle management for the JT15D-1 powerplants—as part of continuing operational readiness under corporate ownership.

The airframe is a member of the Cessna (Textron Aviation) Citation SP family, categorized as a fixed-wing multi-engine light business jet. With a maximum cruise of 352 kts, a service ceiling of 41,000 ft, and a range of 1,328 nm, the aircraft occupies the light business jet performance niche and is configured primarily for executive transport. The combination of its 1979 build year, twin JT15D-1 engines, and corporate ownership profile informs typical maintenance, parts lifecycle, and resale considerations for operators and prospective buyers.
