About the Bombardier Learjet 23

The Learjet 23 is the genesis of the private jet industry. Introduced in 1964, it was designed by Bill Lear based on the Swiss P-16 fighter jet, lending it a legendary reputation for speed and aggressive performance. It is a piece of aviation history that offers fighter-jet-like capabilities to the civilian market, though it demands significant respect and skill from its pilots.

Key Features for GA Buyers

  • Rocket-Like Performance: With a power-to-weight ratio approaching that of fighter aircraft, the Lear 23 boasts an initial climb rate of 6,900 fpm. It can reach 40,000 ft in under 10 minutes.
  • Vintage Appeal: Owning a Lear 23 is owning a classic. It attracts attention on any ramp due to its history and distinctive tip tanks.
  • Entry Price: While operating costs are high, the acquisition cost of these vintage airframes can be surprisingly low compared to modern jets.

Trade-offs

  • Noise Restrictions: The General Electric CJ610 turbojets are extremely loud (Stage 2). Without expensive “hush kits,” this aircraft is banned from operating at many airports in the US and Europe.
  • Pilot Workload: The Lear 23 is a two-pilot aircraft known for demanding handling characteristics, particularly at low speeds. It has a high accident rate historically due to its unforgiving nature.
  • Range & Comfort: The cabin is very small (you cannot stand up), and while fast, the range is limited to approx 1,500 nm, necessitating fuel stops for cross-country trips.
  • Maintenance: Parts scarcity and the age of the airframe (60+ years) make maintenance a challenge for the faint of heart.
