Do FAA Drug and Alcohol Testing Rules Apply to Foreign Repair Stations?

FAA drug and alcohol testing under 14 CFR part 120 now reaches certain repair stations outside the United States. The final rule at 89 FR 103416 (December 18, 2024) added these foreign repair stations to the list of employers that must run testing programs. The FAQ on FAA drug and alcohol testing covered employees gives the overview of who is tested, including a short note on this expansion. This answer goes deeper into the compliance steps, recognition requests and enforcement history.

Who is covered. Section 120.1(d) covers part 145 certificate holders outside the territory of the United States whose employees perform safety-sensitive maintenance functions on part 121 air carrier aircraft. A repair station that works only on aircraft operated under other parts is outside this provision.

Key dates. The rule took effect on January 17, 2025, but the compliance date is December 20, 2027. A covered foreign repair station must obtain an Antidrug and Alcohol Misuse Prevention Program Operations Specification through its FAA principal maintenance inspector and implement its drug and alcohol programs by that date (14 CFR 120.117(c)(2) and 120.225(c)(2)). For a station that begins safety-sensitive work for a part 121 carrier after the compliance date, the FAA's preamble points to filing any request for recognition at least 90 days before it needs to take effect (89 FR 103416). In March 2025 the FAA announced that, following the January 20, 2025 regulatory freeze memorandum, it would not take enforcement action under the rule until March 20, 2025 (90 FR 11668).

How the program works. The foreign repair station must meet the testing subparts of part 120 as if it were an employer, with testing consistent with local law and with the DOT procedures in 49 CFR part 40. That includes the standard test types, such as pre-employment, random and post-accident testing, along with education, training and return-to-duty steps.

Recognition of a home country program. Section 120.10 lets a foreign government, on behalf of its repair stations, or a single repair station ask the FAA to recognize an existing program as a compatible alternative. The request must show three key elements: a testing protocol or set of consequences that detects or deters misuse, an education or training program, and a method to rehabilitate employees who return to work after a violation. A request must be filed at least 90 days before recognition needs to take effect, and it must state that the requester will notify the FAA within 30 days of a change to the key elements. Once recognized, section 120.5 and subparts E and F do not apply, though the recognition letter must be kept on file.

Practical steps. Repair stations abroad should confirm which customers operate under part 121, map the employees doing safety-sensitive maintenance, and decide early between a full part 120 program and a recognition request.
