About the Learjet 24

Type certificated 1966 Source: FAA Type Certificate Data Sheet

Overview

The Learjet 24 is the heavier-gross-weight refinement of the original Lear Jet line: a Part 25 transport-category development of the Learjet 23 that kept the fighter-bred airframe and twin General Electric CJ610 turbojets while raising takeoff weight, certified ceiling, and structural margins. Built from 1966, the 24 carries eight occupants behind the same slender, tip-tanked wing that defined the early Learjet silhouette; the stretched Learjet 25 followed in 1967. Around 260 were produced across the 24/24A through 24F variants before the line gave way to the TFE731-powered Learjet 35/36.

For the GA buyer, the Learjet 24 is caught between a purer collectible and a more practical stretch. Against the Learjet 23 it gains higher gross weight, a 45,000 ft certified ceiling, and a more refined certification basis, but gives up the 23’s standing as the genuine first-of-its-kind original that vintage collectors prize. Against the stretched Learjet 25 it concedes two seats and several feet of cabin for no meaningful gain in speed or economy, which is why many shoppers comparing the two on equal-condition airframes favor the 25. What pins the 24 to a narrow audience is the operating reality every CJ610 Learjet shares: Stage 2 noise that bars unmodified airframes from many fields, fuel burn no modern light jet approaches, and out-of-pocket engine overhauls with no hourly program to smooth them.

Key Features for GA Buyers

  • Fighter-class climb and altitude. A climb rate near 6,800 fpm and a 45,000 ft certified ceiling let the Lear 24 leave weather and airline traffic below it.
  • Speed at a vintage price. A high-speed cruise near 440 knots in an airframe that trades at a fraction of any modern light jet’s acquisition cost.
  • Pilot’s-airplane heritage. Direct, mechanical handling and the classic tip-tanked Learjet silhouette, a flying experience newer designs deliberately engineer away.

Trade-offs

  • Stage 2 noise. The CJ610 turbojets are loud enough that unmodified aircraft are barred from many U.S. and European airports; a Stage 3 hush kit (around $125,000) is often required for practical access.
  • Thirsty turbojets. At roughly 257 gallons/hour the pure turbojets burn far more than any modern turbofan, and there is no engine-program structure to cap overhaul exposure.
  • Two-pilot, high-workload jet. The 24 is two-pilot certificated and demands current jet skills; it is not an entry-level or owner-flown type.
  • Out-of-pocket maintenance. A sixty-year-old airframe with no hourly engine program means overhauls and 12-year inspections land as large, lumpy bills rather than predictable reserves.
