RADAR ESTIMATE

What N1TW is worth, and where it’s heading.

Radar's value model doesn't cover the Learjet 35A on its own yet, so this borrows the Embraer Phenom 300/300E curve, scales it to N1TW's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES

About N1TW

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

Overview

This article concerns airframe N1TW, a 1982-built mid-size business jet of serial number 35A-476 constructed by Gates Learjet Corporation. The aircraft, a Learjet 35A, is owned by NASA 805 LLC, a corporate owner based in Whitefish, Montana, and is registered in the United States. Registered in the US under corporate ownership, the jet’s current status and operator basing are tied to its Whitefish, MT ownership address.

Operations & Cabin

The airframe is configured to accommodate 10 seats, consistent with typical Learjet 35A interiors optimized for executive transport or light air ambulance and special-mission fits. Specific avionics fit and cabin layout for this serial are not published, though the type commonly features a compact six-to-ten passenger cabin with a forward cockpit separated from the passenger compartment; any unique amenities for N1TW are not publicly detailed. Typical mission profiles for a Learjet 35A with a 1,930 nm range and 436 kt cruise include medium-range business travel, quick-response charter, or specialized corporate and corporate-adjacent operations from a Montana base. Maintenance and operational considerations for this particular airframe follow airworthiness and inspection regimes appropriate to an early-1980s airframe under corporate ownership, with base-level upkeep likely managed through specialized third-party shops or owner-arranged facilities.

Model & Market Context

As a member of the Learjet 35/36 family, the Learjet 35A occupies a legacy niche for high-speed, short-to-medium-range light business jets, prized for climb performance to 45,000 ft and efficient turbofan power from the Honeywell TFE731-2-2B engines. Resale and continued operation considerations focus on engine hours, avionics modernization, and compliance with current airworthiness directives for older Learjet airframes.
