2. Executive Company Overview

West Star Aviation is a U.S.-based business aviation maintenance, repair and overhaul organization headquartered in East Alton, Illinois. The company provides heavy and scheduled aircraft maintenance, avionics installation and repair, engine and APU support, exterior paint, cabin refurbishment, engineering, non-destructive testing, component services, AOG response and mobile maintenance across a nationwide service network. Its customer base encompasses individual business-aircraft owners, corporate flight departments, managed fleets, fractional operators and other business aviation operators. Greenbriar Equity Group specifically identifies individual owners, fractional operators and managed fleets among West Star’s customer segments.

West Star’s significance within the private aviation maintenance market comes from the breadth of its airframe coverage and its combination of major MRO facilities with a large field-service organization. The company’s current website reports more than 3,000 employees, six full-service facilities and additional satellite operations, while its AOG division reports more than 250 rapid-response technicians supporting customers nationwide on a 24/7/365 basis.

Its aircraft expertise spans multiple generations of Bombardier Challenger and Global aircraft, Textron/Cessna Citation products, Dassault Falcon aircraft, Gulfstream business jets, Embraer Phenom, Legacy and Praetor families, Hawker aircraft, Learjet aircraft, King Air turboprops and other platforms. West Star holds significant manufacturer and supplier relationships in areas including Embraer maintenance, Textron Aviation-authorized service, engine support and landing-gear overhaul.

The company’s modern scale also reflects substantial consolidation. West Star acquired and combined with Jet East in late 2023, materially expanding its heavy-maintenance, line-maintenance and AOG footprint, before ownership transferred from Sterling to Greenbriar in 2025.
