N501DD

This article concerns airframe N501DD, a factory-built Cessna 501 Citation I/SP completed in 1977 with serial number 501-0035. The jet is owned by DK AIR LLC, an LLC based in Brookings, Oregon, and it is registered in the US. Recorded ownership places the aircraft under a single private LLC operator in Brookings, OR, with no public record here of previous owners or corporate operator changes. The airframe is valued at $600,000, reflecting its age and market position among late-1970s light business jets.

The cabin of this Cessna 501 Citation I/SP is configured for 8 seats, consistent with the model’s light business jet role; typical missions for airframe N501DD would include short- to medium-range corporate hops and private transport within a roughly 1,328 nm radius. Based at Brookings, Oregon under DK AIR LLC ownership, the aircraft’s performance — a long-range cruise near 323 kts and a service ceiling of 41,000 ft — supports coast-to-coast ferry legs with fuel stops or regional charter work along the West Coast. Maintenance and operations for this airframe reflect considerations common to older Pratt & Whitney JT15D-powered Citations, with attention to engine time, airframe corrosion inspection cycles and value-sensitive overhaul scheduling given the aircraft’s stated valuation.

The Cessna 501 Citation I/SP occupies the light twin-jet niche of late-1970s business aviation, offering modest speed and transcontinental capability for its class. Powered by two Pratt & Whitney Canada JT15D-1 engines producing 2,200 lbf each, the type competes historically with other light jets of the era for owner-operators and small charter firms seeking lower acquisition costs. For N501DD, the combination of older vintage, limited production serial status (501-0035) and a market value of $600,000 informs buyer interest and resale considerations, emphasizing thorough inspection records and scheduled maintenance history in transaction evaluations.
