RADAR ESTIMATE

What N123TL is worth, and where it’s heading.

Radar's value model doesn't cover the Cessna Citation S/II on its own yet, so this borrows the Embraer Phenom 300/300E curve, scales it to N123TL's listing-based estimate and widens the range to match. An estimate, not an appraisal.

EQUIPMENT AND HISTORY

As reported in public sources

Cabin
Typical 7-8 passenger executive layout (forward club/aisle/cabin with aft belted lavatory)
Reported incidents
Registration N123TL has historic associations: AAIB bulletin (20 Feb 2002) for a Gulfstream 3 registered N123TL (Coventry) and earlier small-aircraft incidents recorded under the same N-number in public safety databases. Current S/II airframe (S550-0124) shows no recent public accident report.

Listings and registries are not the logbooks. A pre-buy confirms equipment, program status and damage history from the records themselves.

RESEARCH NOTES

About N123TL

Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.

Overview

This entry covers airframe N123TL, a 1987-built Cessna S550 Citation S/II (Citation II) with serial number S550-0124 manufactured by Cessna (Textron Aviation). The aircraft is registered in the US and is recorded as owned by N919Cs LLC (ownership recorded to N919Cs LLC). The airframe's registry history beyond the current owner and initial build details is not published.

Operations & Cabin

The cabin of N123TL follows a typical executive layout for the model, configured for seven to eight passengers with a forward club seating group, an aisle, and an aft belted lavatory as described in the type’s cabin standard. Operationally, the airframe suits short to mid-range corporate missions within its 1,700 nm range and cruise performance near 403 kts; typical usage patterns for this configuration include point-to-point business travel and on-demand charter sectors within the continental US. Specific avionics fit, maintenance status, and base of operations for this registration are not published. Maintenance considerations for this airframe would align with the Citation S/II fleet, focusing on JT15D engine support and airframe corrosion and avionics aging typical of late-1980s production examples.

Model & Market Context

The Cessna S550 Citation S/II (Citation II) occupies the light-citation niche that prioritizes economical twin-engine cruise and access to smaller fields compared with larger jets. With twin Pratt & Whitney Canada JT15D-4B engines delivering roughly 2,500 lbf each, the type competes historically with early-model light business jets in second-hand markets.
