N400ET

This entry documents airframe N400ET, a Cessna 525C Citation CJ4 built in 2012 with serial number 525C0077. The aircraft is owned by SET AIR LLC, a corporate owner based in Rocky Mount, NC, US, and it carries a US civil registration. Registry status and valuation records list the airframe at an estimated value of $6,420,634. Maintenance and operational records specific to this tail number are not published here beyond the stated ownership and valuation.

The airframe N400ET is configured with 10 seats and is operated under US registration out of the owner’s stated location in Rocky Mount, NC, US. Its avionics fit is recorded as Collins Pro Line 21 (typical for CJ4-series), consistent with CJ4-series equipment baselines for flight deck systems. With a maximum cruise of 451 kts and a listed range of 2,165 nm, typical missions for this airframe, as reflected by its equipment and configuration, would encompass medium-range business and corporate transport within the performance envelope provided. The twin Williams FJ44-4A engines, each producing 3,621 lbf, define the propulsion and maintenance considerations for the type as applied to this specific aircraft.

This airframe belongs to the Cessna 525C Citation CJ4 family, a fixed-wing multi-engine light business jet platform produced by Cessna (Textron Aviation). Within its class, the CJ4’s performance figures—highlighted here by a 451 kts cruise, 45,000 ft ceiling, and 2,165 nm range—position the model for buyer and charter demand for fast, transregional missions. For prospective owners or operators of N400ET, resale and maintenance considerations will align with CJ4-series norms, including engine-specific upkeep for the Williams FJ44-4A powerplants and avionics lifecycle issues related to the Collins Pro Line 21 suite.
