UNSPSC 78181813: Aircraft fixed wing hydraulic power repair

Services related to the maintenance of and repairs to aircraft systems that power landing gear, flaps and other flight control systems

UNSPSC 78181813 Aircraft fixed wing hydraulic power repair is a Commodity code. State and local governments soliciting under this code are actually procuring a broader mix of aircraft maintenance, repair, and overhaul services—primarily scheduled and unscheduled airframe maintenance, engine support, avionics repair, and specialized component work on fixed-wing aircraft operated by state aviation divisions, university flight-training programs, and law enforcement agencies. The issuing bodies span state transportation and public safety departments (Texas Department of Transportation, Illinois Department of Transportation, Texas Department of Public Safety, Texas Parks and Wildlife Department, Michigan Department of Natural Resources), a state university system (Texas A&M University System), public universities with flight programs (Middle Georgia State University), and city police aviation units (City of Tampa, City of Tucson). The work solicited includes onsite and offsite maintenance across multiple aircraft types—Beechcraft King Air variants, Cessna models (Citation, piston, and 182), and specialized surveillance systems—with vendors required to hold FAA Certified Repair Station Certificates, demonstrate airframe and power-plant technician credentials, maintain comprehensive aviation liability and hangar keepers insurance, and deliver turnaround times ranging from 30 to 90 days depending on complexity.

Recent activity clusters in Texas and the upper Midwest, with the Texas A&M University System seeking three-year aircraft maintenance services for a mixed fleet under RFP SAIR-26-287 (proposals due August 14, 2026), the Illinois Department of Transportation rebidding as-needed airframe and avionics repair services under IFB 26-494DOT-FINAD-B-52004 (due May 21, 2026), and the Michigan Department of Natural Resources completing award of an aviation radio unit procurement to Great Lakes Aviation Services Inc. for $74,878.51 (Notice of Intent to Award July 6, 2026). Texas Parks and Wildlife Department's RFP for Wescam MX-10 surveillance camera system maintenance on an Airbus H125 helicopter (due April 21, 2026) and Middle Georgia State University's eRFQ for avionics repair services across 53 aircraft and helicopters (due March 23, 2026) round out the geographic spread. Vendors pursuing this code should note that most solicitations are structured as multi-award or cooperative agreements with firm fixed pricing, prequalification or best-value evaluation frameworks, and three- to five-year initial terms, with insurance minimums typically $1,000,000 to $10,000,000 depending on scope and aircraft type.
