What Liberty Partners does

Liberty Partners, Inc. is a privately held aerospace engineering, manufacturing, and FAA certification services firm founded in 2003 and headquartered in Okmulgee, Oklahoma. The company's core business is the design, fabrication, and certification of aircraft modifications and components under a single integrated roof, with a stated specialization in Transmitting Portable Electronic Device (T-PED) tolerance certification. Liberty Partners is the only entity in the industry holding four T-PED Supplemental Type Certificates covering every FAA aircraft certification category (Part 23, 25, 27, and 29), with 3,000+ aircraft certified under the program and additional validations from EASA, ANAC, and Transport Canada.

The product portfolio spans structural and electrical engineering services (FEA, damage tolerance, CFD, RFI/EMI analysis, avionics integration, 3D modeling); precision manufacturing (5-axis CNC machining, CNC turning, large-format routing, fiber laser cutting, composites, and finishing); and end-to-end FAA certification support including STC development, FAA Parts Manufacturing Approval under 14 CFR Part 21 Subpart K, Instructions for Continued Airworthiness, and international validation. The firm operates under AS9100D/ISO 9001:2015 quality systems and holds FAA-PMA authority, enabling both project-based and recurring parts revenue. Go-to-market is direct enterprise sales targeting MROs, OEMs, government/defense organizations (including USDA Forest Service and head-of-state VIP programs), VIP aircraft operators, and rotorcraft operators, supported by an NBAA Maintenance Conference presence and a May 2026 structured partnership with Apcela for legacy aircraft Wi-Fi upgrades ahead of the November 2026 Gogo Classic ATG sunset.

Revenue is generated through a mix of professional services (engineering and certification projects on multi-year contract cycles) and hardware sales (PMA-approved parts and AOG rapid response), with quote-based engagement, fixed pricing on bundled Wi-Fi upgrade programs, and a stated headcount range of 11–50 employees. No public revenue, funding history, or ownership structure is disclosed.
