UNSPSC 78181820: Aircraft fixed wing nitrogen generation system repair

Services related to the maintenance of and repairs to aircraft systems required to fill the void in a fuel tank with nitrogen, to prevent combustion.

UNSPSC 78181820 Aircraft fixed wing nitrogen generation system repair is a Commodity code that sees minimal recent state and local procurement activity aligned with its nominal scope. The recent opportunities tagged to this code span aircraft maintenance, fuel delivery, avionics installation, propeller overhaul, engine support, and airfield ground-equipment services—none of which center on nitrogen generation systems for fixed-wing aircraft. State and local governments do procure aircraft maintenance and repair services at scale, but the opportunities in the source material reflect broader airframe, engine, avionics, and component work rather than the specialized nitrogen generation system repairs that the code nominally describes. Issuing bodies include state departments of transportation and natural resources, municipalities and their police or public-works aviation divisions, county governments, universities operating flight training programs, and special districts managing regional airports. Repeat buyers include the Illinois Department of Transportation (two rebid solicitations for aircraft and airframe maintenance in May and August 2026) and Palm Beach County (two related fuel-procurement notices in September and October 2026).

Activity spans multiple states with heaviest recent concentration in Florida (Palm Beach County fuel purchases, City of Tampa helicopter engine support), Texas (Texas Parks and Wildlife Department equipment maintenance, TxDOT strip and paint services, City of Tucson fuel delivery, City of Waco airport ground-equipment maintenance), Illinois (IDOT airframe services), Michigan (DNR aviation radio procurement), Georgia (Middle Georgia State University propeller overhaul), Nevada (state forestry aircraft maintenance specialist), and New Jersey (state police and environmental protection aircraft maintenance). Representative recent solicitations include the Illinois Department of Transportation's rebid IFB for Beechcraft King Air 350 and Cessna piston airframe services (due August 27, 2026), the City of Tampa Police Department's ITB for Rolls-Royce helicopter engine support services (due April 20, 2026 for a $562,000 estimated contract value), Middle Georgia State University's RFQ for FAA-certified propeller and propeller-governor overhaul (due October 5, 2026), and the New Jersey Department of the Treasury's RFQ for maintenance of aircraft parts and service across 21 aircraft for the State Police Aviation Bureau and Environmental Protection Forest Fire Service (due October 9, 2026). The code shows no direct procurement of nitrogen generation system repair or maintenance in the available source material.
