NIGP 03506: Aircraft Accessories (Not Otherwise Classified)

NIGP 03506 Aircraft Accessories (Not Otherwise Classified), an Item code, encompasses specialized equipment, maintenance, and support services for rotorcraft and fixed-wing aircraft operations across state and local public agencies. Recent solicitations show purchasing focused on helicopter maintenance services, aviation communication device repair and testing, flight helmet systems with fitting services, and aircraft training engines for educational institutions—work driven primarily by law enforcement and emergency-response aviation programs, school district transportation and safety operations, and technical colleges.

County sheriff's offices and city police/fire departments dominate recent activity, with the County of Orange Sheriff-Coroner posting three separate IFBs since April 2026 for helicopter maintenance services, aviation communications device repair, and communications service monitors. The City of Phoenix and Salt Lake City School District represent secondary buyers seeking flight helmet systems and avian exclusion netting for school transportation facilities. Texas State Technical College TSTC–Waco and California's Department of State Hospitals–Atascadero represent lower-volume institutional purchasers. Recent solicitations cluster in California (Orange County, Phoenix, Scottsdale), Arizona, Utah, Texas, and Maryland, with no single state showing dominant concentration. Representative current opportunities include the County of Orange Sheriff-Coroner's IFB for helicopter maintenance services covering five aircraft (two AS350B3, one AS350B2, two UH-1H) with bids due July 16, 2026, structured on hourly labor rates with material costs at actual cost plus markup and requiring mechanics with five years' post-certification experience and FAA Airframe and Powerplant ratings; the City of Phoenix's RFQ for Gentex Alpha Eagle flight helmets, communications equipment, and repair services with offers due July 6, 2026, requiring an authorized distributor with in-person fitting capability in Arizona; and the Orange County Sheriff-Coroner's IFB for maintenance and repair of VHF/UHF radios, transponders, navigation aids, and satellite communications across 59 line items, with bids due September 30, 2026, requiring a brick-and-mortar facility within 55 miles of John Wayne Airport and two-hour emergency response time. Most Orange County solicitations apply 5 percent local small business and disabled veteran business enterprise preferences. Prevailing wage applies to construction-related work; federal grant compliance requirements appear in some Orange County aviation contracts.
