OECO, LLC

OECO, LLC specializes in the design, manufacturing, and maintenance of critical aircraft power systems, with deep expertise in generator sets, current regulators, and auxiliary electrical components for military and homeland security aviation platforms. The company delivers ruggedized, mission-critical power solutions tailored for airborne environments, including repair and sustainment of AC generator systems on MH-65 aircraft. Their technical proficiency spans motor and generator manufacturing, electrical regulation systems, and integrated power subsystems that meet stringent military environmental and performance standards. OECO’s ability to support long-term, firm-fixed-price contracts indicates strong supply chain control, quality assurance processes, and engineering rigor in maintaining operational readiness for high-stakes aerospace applications. The contractor maintains a consistent relationship with the Department of Defense, providing direct support to aviation maintenance and procurement programs through the manufacture and repair of aircraft electrical components. They also serve the Department of Homeland Security with specialized maintenance of generator systems on Coast Guard helicopters, demonstrating an ability to meet the unique operational demands of federal aviation units. Their work reflects a pattern of recurring, mission-critical support rather than one-off procurements, suggesting trusted vendor status within defense and homeland security aviation sustainment ecosystems. OECO’s primary focus lies in NAICS 336413—other aircraft parts and auxiliary equipment manufacturing—where they produce precision electrical components for fixed-wing and rotary-wing platforms. Secondary expertise in NAICS 335312, motor and generator manufacturing, reinforces their vertical specialization in airborne power systems. This positions them as a niche supplier for defense contractors and government maintenance depots requiring certified, flight-qualified electrical subsystems. OECO, LLC is a small business based in Milwaukie, Oregon, operating as a 2L entity with no federal certifications on record. Their geographic presence and technical focus align them with the Pacific Northwest’s aerospace and defense supply chain, serving federal customers through direct manufacturing and repair capabilities rather than broad systems integration.
