Certified Aviation Services

What Certified Aviation Services does

Certified Aviation Services, LLC (CAS) is a privately held US aviation Maintenance, Repair, and Overhaul (MRO) provider founded in 1990 and headquartered in Ontario, California. The company delivers third-party line maintenance services through a network of 15 stations across the United States, supporting more than 100 airline customers with A&P-certified technicians performing daily checks, A-checks, overnight maintenance, and routine inspections aligned to manufacturer specifications. CAS serves commercial airlines, fleet operators, and OEMs across a horizontal commercial aviation segment, with no disclosed revenue and a headcount range of 251–500 employees.

CAS operates four integrated service lines: Line Maintenance (station-based services across 15+ US locations), AOG Go-Team (24/7/365 worldwide emergency rapid response with D100 Authorization for remote operations), Birmingham Airport Dedicated Hangar (a 232,000 sq ft FAA/EASA-certified narrow-body facility with apron capacity for up to 100 aircraft serving heavy maintenance, structural repairs, and lease returns), and Cyclean® Engine Wash (an authorized mobile service using Lufthansa Technik patented technology that washes over 4,000 engines annually and delivers more than 1% fuel flow reduction). The underlying technology is an MRO services platform with integrated quality and safety management systems, including AS9110 certification.

The business model is project- and contract-based professional services revenue, with multi-year contracts for line maintenance, mission- and project-based pricing for AOG Go-Team deployments, scheduled project revenue for heavy maintenance, and per-service pricing for Cyclean® engine washes. Go-to-market is enterprise field sales targeting airlines, fleet operators, and OEMs with dedicated account management, supported by a corporate website, social media presence, and direct sales outreach. No public pricing is disclosed. Recent strategic activity includes a new CFO in November 2025, a Director of Quality Training & Safety in December 2025, and a U.S. Department of Defense SkillBridge industry partnership in March 2026, alongside a longstanding authorized service provider relationship with Lufthansa Technik.
