Action
Final rule.
Summary
This final rule amends the FAA regulations governing drug and alcohol testing to clarify that each person who performs a safety- sensitive function for a regulated employer by contract, including by subcontract at any tier, is subject to testing. These amendments are necessary because in the 1990s, the FAA issued conflicting guidance about which contractors were subject to drug and alcohol testing. This action also rescinds all prior guidance on the subject of testing contractors.
