ETI

What ETI does

ETI INC. is a privately held, FAA-certified aerospace repair and manufacturing company headquartered in Tulsa, Oklahoma, founded in 1983. The company operates as an FAA Part 145 repair station and FAA Part 21 manufacturer specializing in turbine engine component reconditioning and the production of PMA (Parts Manufacturer Approval) replacement parts, serving major worldwide air carriers and third-party MRO companies. Core capabilities include centerless grinding, heat treating, furnace brazing, hardness testing, fluorescent penetrant inspection, welding, machining, and precision measurement using coordinate measuring machines (CMM with a 27x27x22 inch envelope) and micrometers capable of measurements as fine as 0.00005 inch.

ETI's business model is built on direct enterprise sales through a quote/RFQ-based engagement model targeting aerospace operators and MROs. Revenue is generated through FAA Part 145 repair labor and service fees, PMA part sales (one-time licenses for replacement parts), and aero-derivative gas turbine component manufacturing and repair (hardware sales). The company also maintains EASA certification (EASA.145.4434), enabling service to European-registered aircraft, and operates international representation in South Korea through International E&M Corporation.

ETI is diversifying beyond its aerospace legacy through its wholly owned subsidiary Advanced Conversion, which is developing the Power Ring ultra-low-inductance capacitor platform for 800V+ SiC MOSFET-based inverter systems via a strategic partnership with Peak Nano. New product releases targeting Formula E, electric vehicles, buses, heavy trucks, off-highway vehicles, and electrified aviation are planned for late 2026. The company has also launched water treatment chemical compliance services. ETI is founder/owner-operated under Owner Janet Young, with key leadership including General Manager/Accountable Manager Beau Johnson, Quality Control Manager Aaron Pullins, and Engineering Manager Justin Wirt. The firm employs 11-50 people and has not disclosed external funding.
