What PAS MRO does
PAS MRO is an FAA Part 145 certified aerospace repair station founded in 2003 in Irvine, California, and now headquartered in Bristow, Oklahoma (relocated in 2020). The company specializes in the inspection, refurbishment, and overhaul of anti-friction ball and roller bearings used in aircraft engines, airframes, gearboxes, and transmissions, with a flagship offering branded as Bearing Return To Service™ (RTS) that delivers Level I Inspection and Level II Overhaul services at approximately one-third the cost of new OEM bearings and with ~30-day turnaround versus 70+ weeks for OEM replacement. The company also operates an in-house cylindrical roller fabrication capability with precision tolerances under 1 micro-inch diameter roundness and under 1 Ra surface finish, and provides full-cycle component repair and overhaul (disassembly, repair, logistics management, reassembly, final testing) for hydraulic pumps, linear actuators, airframe gearboxes, and line replaceable units, including engineering-driven repair development for legacy and obsolete parts with no OEM repair option.
The company holds FAA Part 145, EASA Part 145, UK-CAA, ISO 9001:2015, and AS9110 certifications, and serves a diversified customer base including major airlines (Boeing, United Airlines, China Airlines), U.S. military (U.S. Air Force, U.S. Army, U.S. Navy/NAVAIR — including UH-60 Blackhawk component work), turbine engine MRO providers (Chromalloy, Consolidated Turbine Specialists, Universal Turbine Parts, Prime Turbines), parts distributors (Dakota Air Parts, Pacific Gear Systems), and helicopter operators (Summit Helicopters), with 150+ active customers across commercial aerospace, defense, industrial, power generation, and marine verticals. Business model is professional services / per-component repair, with quote-based pricing and multi-year contract relationships; go-to-market is enterprise field sales augmented by event-driven lead generation at major aerospace trade shows (MRO Americas, Verticon). PAS MRO was acquired by ATC Group (Air Transport Components), backed by AE Industrial Partners, in April 2026, integrating into a larger MRO platform while retaining existing leadership and operating continuity.
