Summary

No one may use alcohol or a controlled substance after October 28, 1991, in violation of law or government rules and then work as a pilot, flight crew member, airport security screener, airline employee who does safety-sensitive work (as the FAA Administrator decides), or an FAA employee with safety duties. If the FAA finds such use, the person can only return to those jobs after completing the rehabilitation program described in section 45105. Also, the FAA will bar someone from doing the same air-transport duties they had before the finding if they used while on duty, if they had begun or finished the section 45105 rehab before the use, or if they refuse to start or finish that rehab after the FAA’s finding.
