Questions from employers in this region
Boeing builds 787 fuselage sections in Mesa — what FAA and DOD testing applies?
Boeing's Mesa facility performs FAA Part 145 certificated aircraft maintenance activities and DOD defense manufacturing. FAA 14 CFR Part 120 applies to safety-sensitive maintenance functions, and DOD contractor drug-free workplace requirements under FAR 52.223-6 apply to defense contract work. We coordinate collections meeting both FAA and DOD program requirements for Boeing Mesa contractor employers.
Mesa Gateway Airport serves Allegiant and American — does FAA Part 120 apply there?
Yes. 14 CFR Part 120 FAA safety-sensitive testing requirements apply at Mesa Gateway Airport equally as at PHX or TUS. Allegiant Air and American pilots, flight attendants, maintenance personnel, and ground security coordinators at IWA are subject to the same FAA anti-drug and alcohol misuse prevention requirements. We coordinate on-site FAA-compliant collections for carrier employer programs at Mesa Gateway.
