RADAR ESTIMATE
What N171JC is worth, and where it’s heading.
Radar's value model doesn't cover the Gulfstream IV-SP on its own yet, so this borrows the Gulfstream G450 curve, scales it to N171JC's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES
About N171JC
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
This airframe, registered as N171JC, is a 1993-built Gulfstream G-IV (Gulfstream IV-SP) with serial number 1222. It is currently owned by Alliance Aviation Group LLC (a corporation based in Wilmington, DE, US). The airframe presents as a mature mid-1990s Gulfstream IV-SP example with common high-utilization operator ownership and a valuation consistent with later-life VIP-configured long-range business jets.
Operations & Cabin
This specific Gulfstream IV-SP is commonly found in a typical three-zone executive cabin layout, and while VIP fits often accommodate 12-19 passengers, the airframe is certified for configurable seating up to 22. Avionics aboard this hull reflect Honeywell SPZ-8000 installations and follow the common upgrade path to PlaneDeck-family fitments found on many G-IV aircraft. Operated by a corporate entity based in Wilmington, Delaware, the aircraft is suitable for transcontinental and long over-water missions within its published 4,091 nm range and typically cruises at 459 kts to FL450. Maintenance and amenity considerations for this airframe type include aging-system inspections and avionics modernization to PlaneDeck standards to maintain charter or corporate utility.
Model & Market Context
The Gulfstream G-IV/G-IV-SP line occupies a long-range, high-speed business-jet niche characterized by transcontinental capability and executive comfort. Competing models historically include late-model large-cabin business jets offering similar range and speed; demand often hinges on interior condition and avionics modernity. For a 1993 serial 1222, resale and charter marketability depend strongly on the completeness of maintenance records, the condition of the Rolls-Royce Tay 611-8 engines, and any PlaneDeck-style avionics upgrades, all factors that affect lifecycle costs and buyer interest.
