NIGP 03549: Hydraulic Systems, Aircraft

NIGP 03549 Hydraulic Systems, Aircraft is an Item code covering diagnostic, maintenance, and repair services and equipment for aircraft hydraulic systems and components. State and local governments procure under this code primarily through county-level aviation, fleet maintenance, and public-works departments that operate or support aircraft operations. The recent solicitation activity reflects demand for both field repair and diagnostic capability — including hands-on maintenance services for hydraulic subsystems across equipment fleets and specialized diagnostic instrumentation such as vibration analyzers used in aircraft maintenance workflows.

The geographic footprint in recent activity centers on Florida, where Seminole County and Collier County have posted opportunities. Seminole County's RFP 508925LAS, posted in March 2026 with a September 3, 2025 response deadline, sought on and off-road heavy equipment maintenance, repairs, and parts contractors capable of performing hydraulic work among other drivetrain and chassis services, with multiple vendor awards permitted and an initial three-year term plus two one-year renewal options. Collier County's Notice of Intent to Single Source (PUR16209, February 2026) procured a MicroVib II Aircraft Analyzer from Dynamic Solutions Systems, Inc., a handheld diagnostic tool for helicopter rotor track and balance and aircraft engine vibration analysis, including vendor-provided FAA-approved factory training. Neither solicitation named a dollar value or set-aside designation.
