N318SB

The airframe bearing registration N318SB is a production Cessna 525C CitationJet CJ4 built by Textron Aviation Inc. in 2016, constructor serial number 525C0225. The aircraft is recorded as owned by N421VG LLC , a limited liability company based in Houston, TX, US, and is registered in the US. The airframe carries a current market valuation of $7,700,000, reflecting typical post-production condition for a mid‑2010s light business jet of this series. Registry records indicate standard U.S. civil registration status without publicly noted exceptional actions or liens.

The cabin of this CJ4 is configured in an executive 8-place layout consisting of six individual cabin seats plus a right-hand forward two-place couch, supporting small-group corporate transport or owner-flown missions. Forward galley service is provided by a dedicated refreshment center and the aircraft includes a belted flushing toilet for inflight convenience. Avionics are supplied by a Rockwell Collins Pro Line 21 suite incorporating Collins IFIS 5000, Collins TSS-4100 TCAS II, and Collins VHF/Mode S transponders, enabling modern enroute navigation, traffic awareness, and communications for busy airspace operations. Typical mission profiles for this airframe are short- to medium-range point‑to‑point executive trips within the continental United States, leveraging the CJ4’s high cruise speed and long-range capability. Maintenance considerations for this specific aircraft follow manufacturer programs for twin Williams FJ44-4A installations and Pro Line 21 avionics support.

The Cessna 525C CitationJet CJ4 occupies the light‑jet niche aimed at owners and charter operators seeking four‑hour mission capability with eight‑place executive seating and advanced avionics. Competing models in the category include other light-to-midsize business jets offering similar range and speed but differing in cabin volume and operating economics. Demand for CJ4s typically centers on owner/operators and charter fleets valuing runway performance, cruise speed near 400 kts, and a 45,000 ft service ceiling; resale and maintenance considerations emphasize engine and avionics life‑cycle status given the twin Williams FJ44-4A powerplants and the Pro Line 21 suite.
