Other Support Activities for Air Transportation
NAICS 488190 · United States · 2022 edition
This industry comprises establishments primarily engaged in providing specialized services for air transportation (except air traffic control and other airport operations).
Start the review with aviation products and completed operations.
For Other Support Activities for Air Transportation, the saved research highlights aviation products and completed operations, aviation premises/hangar liability, employee injuries. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What specific services are performed — line maintenance, inspections, testing, security screening, or other?
- What types of aircraft are serviced — general aviation, business jets, regional carriers, commercial air carriers?
- Does the operation hold an FAA Part 145 repair station certificate or other relevant regulatory certifications?
- What is the maximum value of any single aircraft that could be in the operation's care at one time?
- Are there any prior aviation-related liability or products claims in the loss history?
- For Other Support Activities for Air Transportation, what should the underwriter know about work on commercial air carrier aircraft (part 121 operations) without a well-documented faa repair station certificate?
- For Other Support Activities for Air Transportation, what should the underwriter know about prior aviation products or completed-operations claims, even partial fault?
- For Other Support Activities for Air Transportation, what should the underwriter know about operations that blur into full overhaul, engine teardown, or major airframe modification?

Establishments in this class provide specialized support services directly tied to aircraft and air transportation — including line maintenance and repair (but not full factory overhaul or rebuilding), aircraft testing, ground support equipment operation, and passenger security screening at airports. Work is typically performed at airport facilities, on the ramp, or at maintenance hangars, often under FAA regulatory oversight and certificate requirements.

- Does the operation hold an FAA Part 145 repair station certificate or other relevant regulatory certifications?
