Greenwich AeroGroup

What Greenwich AeroGroup does

Greenwich AeroGroup, Inc. is a privately held aviation services holding company established in 2007 and headquartered in Wichita, Kansas. It operates a network of five core subsidiaries—Western Aircraft (Boise, Idaho), Summit Aviation (Middletown, Delaware), Summit Aviation Manufacturing (Greensboro/Kernersville, North Carolina and Somerset, Kentucky), Professional Aircraft Accessories (Titusville, Florida), and Professional Aviation Associates (Atlanta, Georgia)—that collectively deliver maintenance, repair, and overhaul (MRO), component repair and overhaul (CR&O), aircraft sales, charter and management, parts distribution, fixed-base operations (FBO), and aerospace manufacturing to general aviation, business aviation, commercial/regional airline, and government/military customers. Each subsidiary functions as an authorized service center, distributor, or dealer for major OEMs including Pilatus, Dassault Falcon, Embraer, Bell, Cessna, Sikorsky, Garmin, Collins Aerospace, Gogo Business Aviation, Williams International, and Liebherr-Aerospace, with cumulative fleet experience of more than 60 years of operating history.

The group's technical capabilities span FAA Part 145 repair station operations, FAA Parts Manufacturing Approval (PMA), AS9110C/AS9120B/ISO 9001:2015/EASA-certified component overhaul, EASA and ANAC-approved STCs, defense-grade aerostructures manufacturing (supporting Boeing, Northrop Grumman, and U.S. Navy programs including Fire Scout and Blue Angels), and proprietary products such as the patented SteerClear steering module cover and the Speed Cowl STC. Western Aircraft is the largest Pilatus dealer globally, performing more than 250 PC-12 inspections annually and 20% of all PC-24 Big Aircraft Modifications worldwide, with 145,000+ work hours on PC-12 aircraft over five years and 20,000+ FAA-approved line items in inventory.

The business model is diversified across six revenue streams: professional services MRO/CR&O (FAA-certified labor), hardware sales (parts distribution and PMA parts), aircraft sales transaction fees (Pilatus franchise plus pre-owned), aircraft management and charter under Part 135 (WestAir Charter), manufacturing sales (aerostructures and assemblies to defense primes), and FBO fuel/line services. Pricing is quote-based and not publicly disclosed; the company sells direct through regional sales teams, account managers, and OEM-authorized dealer channels, and reaches customers via industry events, LinkedIn, YouTube, and subsidiary websites. Customer concentration is moderate, with material exposure to U.S. Navy, Boeing, Northrop Grumman, and Alaska Airlines alongside a long tail of business aviation operators; defense contracts are episodic and project-driven while MRO and parts revenue is recurring by nature.
