N429MS

This article covers the specific airframe N429MS, a Learjet 35A built in 1983 with manufacturer serial number 503 by Gates Learjet Corp. The airframe is registered in the US and is recorded as owned by FCI AERONAUTICS LLC of Marble Falls, TX, US, which is the current operator/home base indicated in available records. The listing notes a 2020 interior refurbishment and an avionics upgrade package, factors reflected in the aircraft’s assessed condition and market valuation of $960,000. No additional historic registry actions beyond the current ownership and US registration are reported in the supplied data.

The cabin of N429MS is described in the listing as an executive layout reported as a 10-place arrangement, with typical Learjet 35A configurations being 8-place club or mixed divan layouts; the specific airframe underwent an interior refurbishment in 2020. Avionics on this airframe were upgraded per the listing and include dual Garmin GTN 750 WAAS GPS, dual Garmin GTX 3000 transponders, a JET FC-200 autopilot and Garmin GWX-70 weather radar, supporting modern IFR operations and situational awareness. With a 2,857 nm range and a cruise speed of 418 kts, this airframe is suited to short-to-medium international or long domestic business missions; operations are typically flown from its Marble Falls, Texas base under the current LLC ownership. Maintenance considerations for this specific aircraft would align with TFE731-series engine program requirements and the value impact of the 2020 interior and avionics upgrades.

The Learjet 35A occupies a light business jet niche noted for high cruise speed, transcontinental/punctuated-range capability and a high-altitude ceiling of 45,000 ft, where the model historically competes with other light jets offering similar speed and range. Typical buyers or charter operators seek efficient point-to-point travel and rapid climb performance; resale considerations for this particular airframe include the upgraded avionics suite and recent interior refurbishment, which support desirability but must be weighed against age (built 1983) and ongoing maintenance costs tied to the airframe and engines. In this market segment, competitive alternatives and maintenance program enrollment influence both operational economics and the realized market value.
