N878DB

This airframe, registered as N878DB, is a 2007-built Gulfstream G550 (Gulfstream G550 (GV‑SP)) with manufacturer serial number 5167. The airframe is recorded as owned by the corporate entity THORONDOR LLC (a corporation based in Palo Alto, CA, US), and its registration is within the US registry. The aircraft’s documented market valuation is $20,590,625, reflecting its mid-life position within the G550 fleet; no additional notable registry actions are published in the supplied data. The combination of build year, serial and corporate ownership situates this G550 as an executive-configured transport maintained for private or charter operations based from its owner’s home region.

This specific G550 is described with a typical executive cabin layout; the model is commonly outfitted for 14–19 passenger executive seating depending on outfitting, while this airframe’s documented seating count is 20, indicating a higher-density or club/meeting configuration. Avionics fit is reported as the manufacturer-standard Gulfstream PlaneView suite (acknowledging that options vary by individual airframe), supporting long-range, high-altitude operations and modern flight management capabilities. Typical missions for this airframe type include transcontinental and intercontinental executive transport within the 6,750 nm range and cruise speeds near 488 kt, operating from the owner/operator’s base region around Palo Alto and other US gateways. Maintenance considerations align with BR710 engine care cycles and Gulfstream structural and systems programs.

The Gulfstream G550 (GV‑SP) occupies a long-range ultra‑long‑range business-jet niche, prized for transoceanic capability and high cruise altitude performance (service ceiling 51,000 ft). Competing models include other large-cabin long-range types offering similar mission profiles; buyer demand historically favors well-maintained, low-cycle airframes with complete records, which directly affects resale value—here reflected by the listed $20,590,625 valuation. Maintenance and resale considerations for this airframe focus on BR710 engine shop visit status, avionics upgrades from the baseline PlaneView fit, and cabin reconfiguration options that can alter passenger capacity and market appeal.
