UNSPSC 25131902: Military transport helicopters

UNSPSC 25131902 Military transport helicopters is a Commodity code that encompasses helicopter maintenance and repair services for sheriff, law enforcement, and emergency services operations. State and local governments procure ongoing maintenance contracts to keep tactical and transport helicopters airworthy, including routine and major inspections, scheduled airframe and engine maintenance to manufacturer specifications, FAA compliance work, and Airworthiness Directives. The issuing bodies are typically county sheriff departments and other local law enforcement or emergency-services agencies operating small tactical helicopter fleets for search and rescue, surveillance, and transport missions. Contractors must hold FAA Mechanic Certificates with Airframe and Powerplant ratings and Inspection Authorization, maintain a certified service center within specified proximity to the customer's base of operations, and provide mechanics with substantial turbine-helicopter experience and factory training on the specific aircraft types in the customer's fleet.

Orange County, California's Sheriff-Coroner department posted IFB #060-3080002-MB on June 18, 2026, with bids due July 16, 2026, for helicopter maintenance services covering five aircraft—one AS350B2, two AS350B3, and two UH-1H helicopters—with an estimated 2,700 flight hours annually. The contract calls for Monday–Friday availability from 6:30 a.m. to 5:00 p.m. Pacific Time with 24/7 on-call coverage, pricing on a per-hour labor basis with a one-hour minimum charge, and material costs at actual cost plus an approved markup. Orange County applies a 5% local small business or disabled veteran enterprise preference deduction (8% if certified as both), and awards based on lowest responsive, responsible bid. The source shows limited recent activity under this code; the Orange County solicitation is a representative example of how state and local governments use the code for specialized helicopter fleet maintenance operations.
