UNSPSC 25201521: Trim tab for rotor blade

An auxiliary airfoil attached to the primary rotor blade in an aircraft engine. It is attached with a hinge on the back of the controlling part serves to reduce power and stabilize the aircraft.

UNSPSC 25201521 Trim tab for rotor blade is a Commodity code that in practice covers helicopter operational support and maintenance services procured by state and local utilities, fire districts, and law-enforcement aviation units for transmission-line inspection, aerial firefighting, and emergency response missions. The recent solicitations show state and local buyers are acquiring not trim tabs themselves but rather full-scope helicopter operator services, engine overhaul and repair, and aircraft lease agreements — suggesting the code's application here reflects the helicopter asset and its component systems rather than a discrete trim-tab part number. The issuing bodies span electric cooperatives (Gulf Coast Electric Cooperative), municipal utilities (Orlando Utilities Commission), police departments (City of Tampa), and fire districts (Consolidated Fire Protection District of Los Angeles County), with a mix of routine maintenance contracting and post-disaster rapid-response capability procurement. Work scopes range from FAA Part 135–certified pilot services for transmission-line inspection flights at slow ground speeds with extended hover time, to in-plant and field engine overhaul and repair for Rolls-Royce Model 250 series engines, to full-term helitanker and intelligence-helicopter lease agreements with integrated support.

Recent activity clusters in Florida and California. Gulf Coast Electric Cooperative's RFP for post-disaster helicopter utility-line inspection (202607, due July 17, 2026, now closed) required 24–48-hour mobilization and continuous 24/7 operations following storms; the Orlando Utilities Commission's RFP 9002 (posted August 31, 2026, response due June 15, 2026) awarded to Chesapeake Bay Helicopters (primary) and Heliservice (secondary) specifies FAA Part 135 certification, slow-speed flight not exceeding 20 knots, hovering capability, and $2 million aviation liability insurance. The City of Tampa Police Department's ITB 26P00177 (posted August 10, 2026, sealed bid due April 20, 2026) procures Rolls-Royce helicopter engine support including overhaul, repair, parts supply, and field service at an estimated annual spend of $275,000 with a five-year maximum contract value of $562,000, designated as a sheltered market for Small Local Business Enterprises with a 5 percent bid discount available. The Consolidated Fire Protection District of Los Angeles County issued an Invitation for Bids (FDCAWD0526, due July 6, 2026) for a three-year helitanker and intelligence-helicopter lease and service agreement with two one-year extension options, funding contingent beyond 2027.
