N503AB

The airframe N503AB is a 2006-built Learjet 60 with manufacturer serial number 311, operated in civilian registry under the United States. The aircraft is recorded as owned by LJ60-311 LLC, a limited liability company based in Memphis, TN, US, and is FAA-registered for operation in the United States. Maintenance and registry records for this specific airframe indicate a mid-2000s build and a contemporaneous avionics fit consistent with late-model Learjet 60 installations; listed market valuation stands at $2,600,000. No additional public ownership transfers or notable incident history are provided in the supplied data.

The cabin of this airframe is described as a typical 7–8 passenger executive club layout while the FAA-registered seating capacity is 11 seats, reflecting flexibility for executive transport or higher-density ferry/positioning missions. Avionics fitments for the model commonly include Collins Pro Line 21 or ProLine IV suites, and this specific airframe lists those systems as the common fitments, supporting modern navigation, communication and flight management capabilities. Typical mission profiles for N503AB would include short to mid-range executive travel consistent with a 2,451 nm range and a high-speed cruise around 453 kts, operating from its owner/operator base in Memphis, TN, US to domestic and regional destinations. Maintenance considerations align with legacy Learjet 60 practices and the PW305A engine maintenance cycle.

The Learjet 60 family occupies a midsize, high-performance light-medium business jet niche, offering transcontinental capability with high cruise speed and 51,000 ft ceiling performance. Competing models occupy similar market segments and buyers often compare range, cabin layout flexibility and installed avionics such as Collins Pro Line 21/IV. Resale and maintenance considerations for this 2006 airframe include engine program status for the PW305A installations, upgrades to avionics where selected, and the aircraft’s recorded valuation of $2,600,000 when assessing market demand for owner-operator or charter fleet acquisition.
