N79SE

This article concerns the specific airframe N79SE, a Learjet 31A built in 2000 with manufacturer serial number 206. The aircraft is owned by CALSPAN LLC, a corporation based in Buffalo, NY, US, and is registered in the US. The entry focuses on this airframe's build details, current corporate ownership and home base rather than broader fleet history; no additional registry transactions or valuation notes are published for this airframe in the supplied data.

The interior of N79SE is configured in an eight-passenger layout with a forward side-facing seat, a mid-cabin four-place club arrangement, and an aft three-place divan. Avionics fitted to this airframe include Honeywell EFIS-50 displays, a KFC 3100 autopilot, Universal UNS-1EW FMS, Honeywell CAS-67 TCAS II, Honeywell RDR-2000 weather radar, and Honeywell Advanced EGPWS, supporting IFR operations and complex flight profiles. Based on the owner’s location, the operator’s base is Buffalo, NY, US, and missions for this configuration typically encompass corporate transport, short-to-medium-range business trips within the aircraft’s 1,631 nm range, and roles that benefit from fast climb and high-altitude cruise to FL510. Maintenance considerations arise from the airframe’s 2000 build year and the twin TFE731 engine type, which has established maintenance practices and parts availability consistent with legacy Learjet support networks.

The Learjet 31A occupies a light, high-performance business jet niche characterized by high cruise speeds (here 441 kts) and service ceilings up to 51,000 ft, appealing to operators seeking rapid point-to-point travel and efficient climb profiles. Competing models in this segment include later light jets and some older midsize entries offering differing cabin comfort, range or operating economics. Buyer and charter demand for a 2000-built Learjet 31A like N79SE typically reflects trade-offs among speed, cabin size (8 seats in this airframe), and the cost of maintaining legacy avionics and engines, with resale and maintenance influenced by completed avionics fits such as the EFIS-50 and integrated TCAS/EGPWS suites.
