NIGP 03506: Aircraft Accessories (Not Otherwise Classified)

NIGP 03506 Aircraft Accessories (Not Otherwise Classified) is an Item code covering specialized equipment, support services, and diagnostic tools that state and local governments procure to sustain rotorcraft and fixed-wing aircraft fleets. Recent solicitations show demand for helicopter maintenance services, flight helmet systems with repair capabilities, turbine training engines for aviation education, aircraft analyzer diagnostic equipment, and helicopter maintenance tracking software. Counties and municipal police and fire departments dominate the buyer base, supported by state higher-education institutions and regional transportation authorities. The County of Orange Sheriff-Coroner Department in California has emerged as a repeat buyer, issuing multiple IFBs and RFQs for helicopter maintenance services, software, and diagnostic tools since February 2026. Solicitations emphasize FAA compliance, manufacturer certifications (particularly Airbus and turbine-engine OEM partnerships), and mechanics or technicians holding valid certifications with multi-year post-certification experience. Performance requirements typically demand local or regional presence for rapid response and maintenance windows. Pricing models vary: helicopter maintenance is frequently quoted on hourly labor rates plus material cost-plus-markup; flight helmets and accessories are per-unit fixed pricing; software is annual subscription-based; and diagnostic equipment commands standalone purchase prices.

Recent activity concentrates in California, Arizona, Texas, Florida, Georgia, and Utah. The County of Orange Sheriff-Coroner solicited helicopter maintenance services (IFB 0603080002MB, due July 16, 2026) for five helicopters—one AS350B2, two AS350B3, and two UH-1H—requiring 2,700 annual flight hours at $24/7 on-call coverage and mechanics with five-plus years' turbine-helicopter experience and factory training; the City of Phoenix issued RFQ 26-0319 (due July 6, 2026) for Gentex Alpha Eagle flight helmets, accessories, and repair services with mandatory Arizona-based OEM certification and in-person fitting capability supporting police and fire helicopter crews. Texas State Technical College at Waco posted RFP 1209144 (due June 10, 2026) for six non-airworthy turboprop training engines and stands for aviation powerplant labs, evaluating on functional specifications (45 points), pricing (30 points), delivery and warranty (20 points), and vendor history supporting Texas higher-education institutions (5 points). The Georgia Department of Natural Resources issued eRFQ 46200DNR0000833 (due May 15, 2026) for UAS Aerial Ignition Systems and support for prescribed burn operations. DBE and local small-business preferences appear in California and Arizona solicitations; no federal Buy American requirements surface except in airport-adjacent procurements funded by federal grants.
