UNSPSC 78181828: Aircraft fixed wing engine exhaust system repair

Services related to the maintenance of and repairs to aircraft units and components which direct the engine exhaust gases overboard, including thrust reverser.

UNSPSC 78181828 Aircraft fixed wing engine exhaust system repair is a Commodity code covering engine and airframe maintenance, repair, and overhaul services for state and local aviation operations. Recent solicitations show state and local governments using this code to procure comprehensive aircraft maintenance — both scheduled and unscheduled — including engine overhaul, avionics repair, field service labor, parts supply, and specialized services such as main rotor blade overhaul and aircraft system refurbishment. The scope encompasses preventive maintenance contracts covering multiple aircraft variants, emergency 24/7 technical support, and factory-authorized repair station services meeting FAA certification and manufacturer standards. Issuing bodies include state departments of transportation and natural resources, university aviation programs, police and fire departments, and municipal aviation divisions, with repeat procurement activity from Texas (TxDOT, Texas A&M, Texas Parks and Wildlife, City of Tucson, City of Tampa) and Illinois (IDOT). The code sees active use across multiple jurisdictions but concentrates in aviation-dependent states with established rotorcraft and fixed-wing fleets.

Recent representative opportunities include the Texas A&M University System's RFP SAIR-26-287 (due August 14, 2026) for three-year aircraft maintenance covering Cessna Citation and Beechcraft King Air aircraft with nationwide service capability, the Illinois Department of Transportation's rebid IFB 26-494DOT-FINAD-B-52004 (due May 21, 2026) for Beechcraft King Air 350 and Cessna airframe repair across 16 line items, the City of Tampa Police Department's ITB 26P00177 (due April 20, 2026) for Rolls-Royce Model 250 helicopter engine support including overhaul and field service, and the Texas Parks and Wildlife Department's RFP for Wescam MX-10 surveillance camera system maintenance on an Airbus H125 helicopter (due April 21, 2026). The Michigan Department of Natural Resources awarded a P-25 compliant aircraft aviation radio installation contract to Great Lakes Aviation Services Inc. for $74,878.51. Contracts typically require FAA Certified Repair Station certification, comprehensive aviation liability insurance ($1 million to $10 million per occurrence), proven track records with 20+ maintenance work orders in the prior 12 months, and integration with state asset management systems. Initial terms run two to three years with renewal options, and most jurisdictions evaluate on best-value or lowest-price-responsive-and-responsible criteria rather than set-asides.
