PRICE: A ROUGH RANGE
Learjet 31 (certified family) price: a rough range by build year.
Radar's value model does not cover the Learjet 31 (certified family) yet, so this is a rough range, not an estimate for any one aircraft. From Radar's listing-based estimates for business jets of similar engine thrust and age. The band is the range for each build year and the line its middle. Hours, engines, damage history, equipment and the logbooks move the price of any one aircraft.

QUESTIONS
Learjet 31 (certified family) questions, answered from the data
How much does a Learjet 31 (certified family) cost?
Radar's rough range is about $460K to $1.5M for a 1990 and $460K to $1.5M for a 1988. From Radar's listing-based estimates for business jets of similar engine thrust and age. These are rough ranges, not appraisals: hours, engines, damage history, equipment and the logbooks move the price of any one aircraft.
What affects the price of a Learjet 31 (certified family)?
What moves the price of any one Learjet 31 (certified family): total time and engine time, engine program enrollment, damage history, avionics and equipment, and complete logbooks. Build year sets the baseline shown on this page; a Learjet 31 (certified family) with high hours, an engine near overhaul or gaps in its records sells below it, and one with low time, recent inspections and full records above it.
Where can I find a Learjet 31 (certified family) for sale?
Radar does not list aircraft for sale. It tracks all 12 US-registered Learjet 31 (certified family)s by tail number, each with its registration record and a value estimate, so you can check a listing against the value of its build year and look up the aircraft's own history before you call.
How many Learjet 31 (certified family)s are there?
12 Learjet 31 (certified family)s are on the US civil aircraft register (FAA file of October 2026), built 1988 to 1990. Aircraft registered in other countries are not counted. Radar has a page for each US registration.
Who owns Learjet 31 (certified family)s?
Of the 12 US-registered Learjet 31 (certified family)s, 12 (100%) are registered to companies, trusts and other entities and 0 to individuals. Radar names entity owners only; individuals are shown as privately registered. The most common states of registration are DE (4), TX (2), FL (1).
Operate a Learjet 31 (certified family)? Put its logbooks in Radar.
Radar reads every logbook page, typed or handwritten, and builds one searchable record per tail: times, inspections, ADs and components, each tied to the page it came from.
