SUPPLEMENTARY INFORMATION: 

I. Executive Summary 

On December 7, 2023, the FAA 

published the NPRM, Drug and Alcohol 

Testing of Certificated Repair Station 

Employees Located Outside of the 

United States.1 This proposed rule, 

which the FAA is required by statute to 

promulgate, would implement a 

statutory mandate to require certificated 

part 145 repair stations located outside 

the territory of the United States (U.S.) 

to ensure that employees who perform 

safety-sensitive maintenance functions 

on part 121 air carrier aircraft are 

subject to a drug and alcohol testing 

program, consistent with the applicable 

laws of the country in which the repair 

station is located. This proposed rule 

would require a part 145 repair station 

located outside the territory of the U.S. 

to implement a drug and alcohol testing 

program meeting the requirements of 49 

CFR part 40 and 14 CFR part 120, which 

must cover its employees who perform 

maintenance functions on part 121 air 

carrier aircraft. If a part 145 repair 

station cannot meet one or all 

requirements in 49 CFR part 40 (e.g., the 

laws of the country where the repair 

station is located are inconsistent with 

the regulations), the part 145 repair 

station may apply for an exemption 

using the process described in 49 CFR 

40.7. Similarly, if a part 145 repair 

station cannot meet one or all 

requirements in 14 CFR part 120, it may 

apply for a waiver in accordance with 

proposed waiver authority. This rule 

would affect approximately 977 part 145 

repair stations in about 65 foreign 

countries.2

It is the responsibility of the employer 

(e.g., the part 121 operator) to ensure 

that any person who performs safetysensitive functions (e.g., maintenance or 

preventive maintenance), directly or by 

contract (including by subcontract at 

any tier), is subject to drug and alcohol 

testing. The FAA notes that part 145 

repair stations located within the 

territory of the U.S. may elect to, but are 

not required to, implement a drug and 

alcohol testing program under 14 CFR 

part 120. When hiring by contract, if a 

part 145 domestic repair station does 

not have a testing program of its own, 

the part 121 operator must cover the 

repair station’s safety-sensitive 

employees under its FAA drug and 

alcohol testing program.3 In this 

scenario, for purposes of drug and 

alcohol testing, the part 121 operator 

hires the repair station employees as 

covered employees 4 and must apply all 

the regulatory requirements of the 

program to these employees (e.g., 

conduct a pre-employment drug test, the 

records check, the training and 

educational information distribution 

requirements, and include the 

individuals in the random testing pool). 

Therefore, all employees performing a 

safety-sensitive function within the U.S. 

are part of a drug and alcohol testing 

program, whether it is the part 121 

operator’s program or the repair 

station’s program. As further discussed 

in this preamble, the FAA does not 

propose any changes to its current drug 

and alcohol testing requirements 

applicable to employees performing a 

safety-sensitive function within the U.S. 

as part of this rulemaking. In addition, 

the FAA invites comments, with 

supporting data, on whether the drug 

and alcohol testing requirements in this 

proposed rule should be extended to 

safety sensitive maintenance employees 

of part 121 certificate holders located 

outside the United States. 

II. Extension of Comment Period 

Commenters were instructed to 

provide comments to the NPRM on or 

before February 5, 2024, (i.e., sixty (60) 

days after publication of the NPRM). 

Subsequently, on January 16, 2024, the 

FAA received a request from 15 

organizations to extend the comment 

period an additional ninety (90) days.5

Commenters cited the holiday season 

and the complexity, including 

international ramifications, as reasons 

for requesting the extension. 

The FAA grants the petitioners’ 

request for an extension of the comment 

period. The FAA recognizes the 

importance of the proposed rule and 

that an extension would help 

commenters craft complete and 

thoughtful responses. However, the 

FAA believes that an additional sixty 

(60) days provides sufficient 

opportunity to review the NPRM and 

provide comments. With this extension, 

the comment period will now close on 

April 5, 2024. This will provide the 

public with a total of one hundred 

twenty (120) days to conduct its review 

and submit comments to the docket. 

The FAA will not grant any additional 

requests to further extend the comment 

period for this rulemaking. 

III. Additional Information 

A. Comments Invited 

The FAA invites interested persons to 

participate in this rulemaking by 

submitting written comments, data, or 

views. The Agency also invites 

comments relating to the economic, 

environmental, energy, or federalism 

impacts that might result from adopting 

the proposals in this document. The 

most helpful comments reference a 

specific portion of the proposal, explain 

the reason for any recommended 

change, and include supporting data. To 

ensure the docket does not contain 

duplicate comments, commenters 

should submit only one time if 

comments are filed electronically or 

commenters should send only one copy

of written comments if comments are 

filed in writing. 

The FAA will file in the docket all 

comments it receives, as well as a report 

summarizing each substantive public 

contact with FAA personnel concerning 

this proposed rulemaking. Before acting 

on this proposal, the FAA will consider 

all comments it receives on or before the 

closing date for comments. The FAA 

will consider comments filed after the 

comment period has closed if it is 

possible to do so without incurring 

expense or delay. The FAA may change 

this proposal in light of the comments 

it receives. 

Privacy: In accordance with 5 U.S.C. 

553(c), DOT solicits comments from the 

public to better inform its rulemaking 

process. DOT posts these comments,

IV. Extension of Comment Period 

In accordance with § 11.47(c) of title 

14, Code of Federal Regulations, the 

FAA has reviewed the petitions for 

extension of the comment period for 

this notice. The petitioners have shown 

a substantive interest in the proposed 

policy and good cause for the extension 

of the comment period. The FAA has 

determined that an extension of the 

comment period for an additional sixty 

(60) days to April 5, 2024 is consistent 

with the public interest, and that good 

cause exists for taking this action. 

Accordingly, the comment period for 

Notice No. 24–05 is extended until 

April 5, 2024.
