N91SU

The airframe bearing tail number N91SU is a 2015-built Learjet 45, serial number 528, manufactured by Learjet Inc.. The US-registered jet is recorded in the registry as owned by a corporation; the registry entry lists no public owner name or location, and there are no published details of operator changes or notable registry actions. Condition and valuation highlights are not published for this specific airframe in the supplied data. The registry mirror lists a 12-seat layout for this specific aircraft, which differs from many factory-standard executive configurations.

The registry mirror for N91SU indicates 12 seats aboard this Learjet 45 airframe, though typical Learjet 45 cabins are configured with 8–9 executive seats and options such as double-club seating, a galley, and a forward lavatory are common; this suggests this airframe may be arranged for higher-density passenger carriage or special mission roles. Avionics fit for the model is noted as Honeywell Primus in typical fits, with a possibility that late-model or retrofitted examples carry G5000 or other STC upgrades, but no specific STC or retrofit history is published for this serial. With a cruise speed of 436 kts and a maximum service ceiling of 51,000 ft, operations for this airframe would commonly include fast, short- to mid-range point-to-point business or corporate missions across domestic and near-international routes compatible with its 1,968 nm range. Maintenance considerations align with twin Honeywell TFE731-series engine logistics and typical light-jet airframe upkeep practices; no unique maintenance records are provided.

As a Learjet 45 built in 2015, serial 528, this airframe sits within a light business jet performance niche characterized by high cruise speeds and high-altitude capability for efficient point-to-point transport. The twin Honeywell TFE731-40BR-1 engines and the stated range and ceiling define operational flexibility for transcontinental U.S. routing without long international legs. Buyer and charter demand drivers for this airframe would generally be influenced by its 12-seat registry allocation, avionics fit, and engine variant; resale and maintenance considerations hinge on documented ownership, refurbishment or STC avionics upgrades, and the absence or presence of published valuation and condition records for this specific aircraft.
