N391DT

This airframe, registered as N391DT, is a 1989-built Cessna 550 Citation II with serial number 5500620. Manufactured by Cessna (Textron Aviation), the airframe is recorded as owned by SUMMIT NV LLC, a Nevada limited liability company based in Reno, NV, US, which serves as the operator/home base. The airframe’s US registration and corporate ownership are notable administrative markers in its registry history, and its reported market valuation stands at $922,375, reflecting its late-1980s vintage and equipment fit. Maintenance condition and specific recent registry actions are not published beyond the current ownership record.

The airframe is configured in a typical eight-place executive cabin with an enclosed aft lavatory and a forward service/galley, supporting corporate transport and short- to mid-range executive missions. Avionics fit is reported to include a legacy Sperry SPZ-500 integrated flight control system and HF radio equipage, permitting long-range communications and conventional automated flight guidance for its era. Typical operations for this specific airframe would include point-to-point regional and transcontinental executive transport within its 1,378 nm range and at cruise speeds around 369 kt. Based in Reno, NV, the operator would likely employ the aircraft for charter or corporate missions across the western United States; maintenance considerations center on aging avionics and systems common to late-1980s airframes and the JT15D-4 engines’ lifecycle.

The Cessna 550 Citation II sits in the light-to-midsize business jet niche, offering higher cruise speed and ceiling relative to earlier light jets while retaining economical operating characteristics. Competitors historically include light-cabin types from Beechcraft and Learjet variants; buyer and charter demand for Citation IIs often focuses on affordability and parts availability. Resale and maintenance considerations for this airframe hinge on avionics obsolescence, engine program status for the JT15D-4s, and the airframe’s documented corporate ownership and valuation.
