UNSPSC 78181830: Aircraft fixed wing engine wash service

Specialized services related to the process of aircraft engine cleaning resulting in lower exhaust gas temperatures and reduced fuel demand

UNSPSC 78181830 Aircraft fixed wing engine wash service, a Commodity code, does not align with state and local procurement activity currently on file. Recent opportunities tagged under this code span jet fuel procurement, helicopter engine overhaul and support, fixed-wing airframe and avionics repair, propeller overhaul, aircraft maintenance and painting, and aviation radio installation—none of which constitute engine wash services as the code nominally describes. The mismatch suggests either inconsistent code assignment in state and local procurement systems or a category so narrowly specialized that wash-specific solicitations rarely appear in public notice databases.

State and local issuing bodies pursuing aircraft maintenance and repair work include city and county aviation divisions (Tampa Police Department, Waco Regional Airport, Tucson Police Department), state departments of transportation and natural resources (Illinois Department of Transportation, Texas Department of Transportation, Texas Parks and Wildlife Department, Michigan Department of Natural Resources), university flight operations (Texas A&M University System, Middle Georgia State University), county procurement offices (Palm Beach County), and regional authorities. Geographic activity spans Florida, Texas, Georgia, Illinois, Michigan, Arizona, and Nevada. Representative recent opportunities include Illinois Department of Transportation's rebid for Beechcraft King Air 350 and Cessna piston airframe services, with an IFB due August 27, 2026; Texas Parks and Wildlife Department's RFP for Wescam MX-10 camera system maintenance on an Airbus H125 helicopter, due April 21, 2026; Texas A&M University System's RFP for scheduled and unscheduled maintenance on three Cessna and Beechcraft aircraft, due August 14, 2026; and New Jersey Department of the Treasury's supplemental maintenance and parts procurement for 21 aircraft across Bell, Cessna, Piper, and Agusta AW139 platforms, quotes due October 9, 2026. Because this code does not capture the actual work being solicited, firms pursuing state and local aircraft maintenance and repair contracts should verify code assignment in specific solicitations rather than rely on this category designation.
