N418AB

This article covers airframe N418AB, a mid-size business jet listed as a Learjet 45 with manufacturer serial number 537. Build year: Not published. The airframe is owned by NIX PATTERSON LLP, a partnership based in Austin, TX, US, which serves as its operator/home base for corporate operations. Registered on the U.S. civil registry and operated in partnership service, the jet is equipped and maintained to typical executive standards for the type. Valuation and condition highlights for this specific airframe list an estimated market value of $2,400,000, indicating a mature example of the model with residual value consistent with older Learjet 45s in active corporate service.

The cabin of N418AB follows a typical executive double-club layout, commonly configured in the Learjet 45 fleet for 8–12 seats, with the registry listing 12 seats for this airframe; the interior supports corporate shuttle, short international hops, and owner/operator missions. Avionics are consistent with the fleet standard, fitted with the Honeywell Primus 1000 suite, providing modern flight management, navigation and integrated displays for single-pilot or two-pilot operations depending on operator procedures. Typical missions for this airframe include medium-range business travel within the continental U.S. and to nearby international destinations, leveraging the jet’s cruise speed and high-altitude ceiling for efficient routing. Maintenance considerations follow established Learjet 45 line and component programs centered on the Honeywell TFE731 powerplants and Primus avionics commonality.

The Learjet 45 family occupies a performance niche as a light/mid-size business jet emphasizing speed, altitude capability, and short-field performance; N418AB reflects those traits with a 445 kts cruise and 51,000 ft ceiling. Competing models in its era include other entry-level midsize jets sharing similar range and cabin size; buyer and charter demand for used examples is driven by price, operating costs, and avionics/engine status. Given the listed market value of $2,400,000, resale considerations for this airframe center on airframe hours, engine cycles on the TFE731-20 engines, and avionics upgrade paths from the baseline Honeywell Primus 1000 fit.
