UNSPSC 78181900: Rotary wing aircraft maintenance and repair services

Services spanning inspection, maintenance and repair, including overhaul of rotary wing aircraft of all kinds

UNSPSC 78181900 Rotary wing aircraft maintenance and repair services is a Class code that encompasses scheduled and unscheduled maintenance, inspections, repairs, overhauls, and emergency field support for helicopters and rotary-wing aircraft operated by state and local agencies. State and local buyers under this code include state departments of transportation, law enforcement and forestry divisions, municipal police departments, county sheriffs, university aviation programs, and specialized aviation authorities. The work spans routine 100-hour and annual inspections, engine and airframe overhauls, component repair and replacement, avionics and instrument services, parts supply with capped markups, field emergency response, and warranty coverage. Buyers frequently require FAA Airframe & Powerplant certification or FAA Repair Station certification as mandatory qualifications, along with manufacturer authorization for proprietary aircraft platforms. Recent solicitations emphasize response speed—many require emergency on-ground (AOG) response within 24 hours and scheduled maintenance turnaround within 30–45 days. Insurance requirements typically include $1 million to $10 million aviation liability, hangar keepers liability, and general commercial liability coverage.

Rotary-wing procurement activity spans multiple states with recent solicitations concentrated in Florida, California, Illinois, Texas, and Michigan. The Florida Department of Law Enforcement issued an Invitation to Negotiate in May 2026 for fixed and rotary-wing maintenance covering four Bell B206B/TH-57 helicopters and six fixed-wing aircraft, with responses due July 28, 2026.
