Drug and alcohol testing of safety-sensitive aviation employees helps protect public safety and keep our skies safe. Testing is required by the Omnibus Transportation Employees Testing Act of 1991 and by DOT and FAA regulations (49 CFR part 40 and 14 CFR part 120).
The Drug Abatement Division oversees the aviation industry’s compliance with the drug and alcohol testing law and regulations. They accomplish this by performing on-site inspections, providing guidance to companies, individuals, contractors, and service agents, and establishing policies and procedures to increase the program’s effectiveness.
