WASHINGTON (Reuters) - The Federal Aviation Administration said Monday it has finalized rules requiring aviation-repair stations in foreign countries to conduct drug and alcohol testing for employees performing safety-sensitive maintenance functions for U.S. airlines.

The rule, which requires compliance by December 2027, will impact approximately 977 repair stations in 65 countries, the FAA said. The agency said Monday that foreign governments or repair stations can obtain a waiver based on existing testing and requirements.
