RADAR ESTIMATE

What N136DH is worth, and where it’s heading.

Radar's value model doesn't cover the Learjet 36A on its own yet, so this borrows the Embraer Phenom 300/300E curve, scales it to N136DH's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES

About N136DH

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

Overview

The airframe bearing registration N136DH is a Gates Lear Jet-built Learjet 36A completed in 1977, with manufacturer serial number 036. The airframe is recorded as owned by the corporate trustee CSC Delaware Trust Co Trustee, located in Wilmington, DE, US, and carried United States registration US. Notable registry entries and the corporate trustee ownership suggest use under corporate or trust-based stewardship rather than individual private ownership.

Operations & Cabin

This specific Learjet 36A is outfitted in a special-mission mapping configuration, with photographic reporting of a belly radar/pod installation that modifies the standard Learjet cabin and lower fuselage fairings. The interior seating count is reported as 10, but the mission fit likely replaces or restructures standard executive appointments to accommodate mission equipment, racks and operator positions. Typical mission profiles for this aircraft as configured would emphasize long-range, high-speed mapping sorties within its 2,857 nm range and cruise at approximately 418 kts, operating from corporate or government contractor bases, registry location points to a Wilmington, Delaware administrative base. Maintenance considerations for this airframe include support for the Garrett TFE731 turbofan series and inspection of mission-specific belly installations and their structural and systems interfaces.

Model & Market Context

The Learjet 36A occupies a light-cabin, long-range niche in the 1970s-era business jet market, notable for high cruise speed and transcontinental capability for its class. Competing types historically included early mid-size business jets offering similar speed-range tradeoffs; the 36A’s Garrett TFE731 engines are valued for efficiency but require experienced heavy-jet maintenance shops.
