Aero Propulsion Support, Inc. is a US-based aerospace MRO specialist focused exclusively on small gas turbine engine components. Headquartered in Harrison, Ohio, the company positions itself as dedicated to being the best small gas turbine component shop in the world, supporting auxiliary power units, turboshaft, turboprop and small turbofan engines used across rotary-wing, fixed-wing and ground support applications. The company combines engineering support, component repair services and inventory management for aerospace propulsion systems. Its in-house capabilities cover the full repair workflow for hot-section and cold-section parts: GTAW/TIG and micro welding, laser beam welding and cutting, five-axis conventional and non-conventional CNC machining, high-temperature brazing (including honeycomb brazing), thermal spray, abradable and protective coatings, and heat treating. Component-level work includes restoration of turbine nozzles, blades, shrouds, combustors, bearing supports and compressor diffusers. A dedicated quality function performs liquid penetrant inspection, ultrasonic testing and pressure testing. Aero Propulsion is an approved supplier to the major small-engine OEMs — General Electric, Honeywell, Rolls-Royce, Pratt & Whitney Canada and Hamilton Sundstrand — and supports engine families including the Rolls-Royce 250 series, Honeywell GTCP/TPE/TSCP APUs and turboprops, GE CT7/T700/CJ610/CF700/CF34, P&W Canada PT6 and PW901A, and APS-series APUs. The business operates from a single Ohio facility under FAA Repair Station certification (#YULR908L), with parallel EASA and UK CAA approvals enabling export of repaired components to operators in Europe and the United Kingdom. The company states 31 years of operating history and a customer footprint extending across 25 countries.
