Summary

You cannot use alcohol or illegal drugs after October 28, 1991 in a way that breaks the law or a U.S. government rule and work as an airman, crewmember, airport security screener, an air carrier employee who does safety‑sensitive work (as the FAA Administrator decides), or an FAA employee with safety‑sensitive duties. If you are found to have used alcohol or drugs after that date in violation of law or a government rule, you may only hold those jobs again if you finish the rehabilitation program under section 45105. If the FAA Administrator finds that someone in those jobs used alcohol or illegal drugs after October 28, 1991 in violation of law or a government rule, that person cannot return to the same air‑transport duties they had before the finding if any of these are true: they used while on duty; they had started or finished the rehab program in section 45105 before they used; or they refuse to start or finish the rehab program after the FAA finding.
