UNSPSC 78181834: Aircraft fixed wing nacelle and pylon repair

Services related to the maintenance of and repairs to the outer casing that houses and carries aircraft engines

UNSPSC 78181834 Aircraft fixed wing nacelle and pylon repair, a Commodity code, does not align with the work state and local governments are actually procuring under this classification. The recent opportunities tagged with this code span jet fuel supply and delivery, helicopter engine and propeller overhaul, aircraft radio and avionics installation, airframe and component maintenance across multiple aircraft types, and baggage handling system repair—a scope far broader than nacelle and pylon repair alone and reflecting a fundamental mismatch between the code's nominal title and the operational procurement activity it labels. State and local agencies issuing under this code include counties (Palm Beach County), cities (Waco, Tampa, Tucson), state departments (Illinois DOT, Texas DOT, Michigan DNR, Texas Parks and Wildlife), university systems (Texas A&M, Middle Georgia State), and state purchasing divisions acting on behalf of specialized divisions (Nevada Division of Forestry, New Jersey State Police Aviation Bureau). The issuing bodies operate law enforcement aviation units, state forestry operations, university flight training schools, and transportation agency air support divisions.

Recent activity spans the South (Florida, Texas), Midwest (Illinois, Michigan, Ohio), and West (Nevada), with Florida and Texas showing multiple concurrent solicitations. Representative recent opportunities include Palm Beach County's dual IFBs for Jet A fuel purchase, transport, and delivery with responses due November 5, 2026 (IFB68026059BB2 and IFB68026059BB3); the City of Waco's RFP 2026-055 for on-call baggage handling system and passenger boarding bridge maintenance at Waco Regional Airport (proposals due October 20, 2026); the Illinois Department of Transportation's rebid IFB B-52781 for Beechcraft King Air 350 and Cessna airframe maintenance with estimated line-item costs from $5,000 to $250,000 (bids due August 27, 2026); the City of Tampa Police Department's ITB for Rolls-Royce Model 250 helicopter engine support services with an estimated annual expenditure of $275,000 and total estimated contract value of $562,000 across the award and renewal period (bids due April 20, 2026); and the New Jersey Department of the Treasury's supplemental aircraft maintenance solicitation for the State Police Aviation Bureau and Environmental Protection Forest Fire Service covering 21 aircraft across four groups with quotes due October 9, 2026. The code shows substantial and geographically dispersed procurement activity, though the mismatch between the code title and the actual scope of work solicited suggests that procurement systems are applying this classification inconsistently or as a catchall for aviation maintenance work.
