N545SB

This airframe, registration N545SB, is a 2005-built Learjet 60 with manufacturer serial number 60-290 constructed by Learjet Inc. The aircraft is owned by Sierra Bravo LLC (an LLC based in Galveston, TX, US), which serves as the listed operator and home base for the airframe’s civil registry. The Learjet has a typical mid-life valuation of approximately $3,000,000 and reflects a configuration and equipment level consistent with later-serial Learjet 60s; ownership under Sierra Bravo LLC represents the primary recorded custodial history available for this specific tail number. No other public registry actions are recorded within the supplied data.

The cabin for N545SB is FAA-certified for 11 seats, though many Learjet 60 examples are commonly reconfigured to 6–8 executive seats for corporate missions; this airframe’s certification allows for either dense seating or executive layouts depending on owner modification. Avionics fit noted for this airframe is the common Learjet 60 series installation of Rockwell Collins Pro Line 4, supporting modern flight management, navigation and situational awareness for long-range executive operations. Typical missions for this aircraft type and this airframe include transcontinental and regional business flights within the approximately 2,405 nm range at cruise speeds near 436 kts and flight levels up to 51,000 ft. Maintenance considerations align with mid-2000s Learjet 60 airframes: two PW305A engines with lifecycle management and avionics support for Pro Line 4 systems.

The Learjet 60 occupies a performance niche as a light to midsize business jet with high cruise speed and high-altitude capability, appealing to buyers seeking fast point-to-point transport. In the market, the model competes with contemporary light-midsize cabins from other manufacturers where buyer demand focuses on speed, short runway performance and efficient transcontinental capability. Resale and maintenance considerations for this airframe reflect its 2005 vintage, engine type (PW305A), and avionics package (Pro Line 4), all factors that influence operating costs and marketability at a valuation near $3,000,000.
