N357EK

This entry describes airframe N357EK, a 2021-built Cessna 525C Citation CJ4 with builder serial 525C0357. The aircraft was manufactured by Textron Aviation Inc and is registered in the United States, currently owned by LIGHTNING LEASING LLC of Ponca City, Oklahoma, which functions as the listed operator/registrant. The airframe's broker-advertised valuation is $5,550,684 and the listing includes condition and equipment highlights such as a premium Glacier interior and an avionics fit based on Collins ProLine components. No other registry actions or prior owners are published in the supplied data.

The cabin for this specific airframe is described as a nine-passenger premium Glacier interior with a forward two-place divan, a four-place club configuration, two aft forward-facing seats and a belted lavatory as listed by the broker; overall certification and supplemental documentation support an 11-seat layout. Avionics equipment listed for this aircraft includes Collins ProLine (Collins ProLine 21 / FMS-3000), TCAS, Collins radios and ADS‑B Out capability, enabling modern navigation and traffic awareness for charter and corporate missions. With a 2,165 nm range and a high cruise speed of 451 knots, typical operations for N357EK would include regional to transcontinental charters and rapid point-to-point corporate travel from its home base in Ponca City, OK. Maintenance considerations for this airframe follow standard CJ4 programs, with attention to Williams FJ44-4A engine cycles and avionics software/FMS updates.

The Cessna 525C Citation CJ4 occupies the light to mid-size business jet niche, offering high cruise speed, a 45,000 ft ceiling and transcontinental capability for its class. Common competitors in its mission and price band include other light jets and small midsize models that balance cabin comfort and operating economics. Buyer and charter demand tends to favor well-equipped CJ4s with ProLine avionics and premium interiors; resale value and marketability for N357EK will be influenced by engine time, avionics logbooks, and the documented Glacier cabin refurbishment. Maintenance and resale considerations particularly emphasize adherence to CJ4 Cchecked schedules, Williams FJ44 engine programs and currency of avionics databases.
