§ 120.105 Employees who must be test-

ed. 

Each employee, including any assist-

ant, helper, or individual in a training 
status, who performs a safety-sensitive 
function listed in this section directly 
or by contract (including by sub-

Feb. 21, 2014] 

§ 120.107 Substances for which testing 

must be conducted. 

Each employer shall test each em-

ployee who performs a safety-sensitive 
function for evidence of a prohibited 
drug during each test required by 
§ 120.109. 

[84 FR 16773, Apr. 23, 2019] 

§ 120.109 Types of drug testing re-

quired. 

Each employer shall conduct the 

types of testing described in this sec-
tion in accordance with the procedures 
set forth in this subpart and the DOT 
‘‘Procedures for Transportation Work-
place Drug Testing Programs’’ (49 CFR 
part 40). 

(a) 

Pre-employment drug testing. 

(1) No 

employer may hire any individual for a 
safety-sensitive function listed in 
§ 120.105 unless the employer first con-
ducts a pre-employment test and re-
ceives a verified negative drug test re-
sult for that individual. 

(2) No employer may allow an indi-

vidual to transfer from a nonsafety- 
sensitive to a safety-sensitive function 
unless the employer first conducts a 
pre-employment test and receives a 
verified negative drug test result for 
the individual. 

(3) Employers must conduct another 

pre-employment test and receive a 
verified negative drug test result be-
fore hiring or transferring an indi-
vidual into a safety-sensitive function 
if more than 180 days elapse between 
conducting the pre-employment test 
required by paragraphs (a)(1) or (2) of 
this section and hiring or transferring 
the individual into a safety-sensitive 
function, resulting in that individual 
being brought under an FAA drug test-
ing program. 

(4) If the following criteria are met, 

an employer is permitted to conduct a 
pre-employment test, and if such a test 
is conducted, the employer must re-
ceive a negative test result before put-
ting the individual into a safety-sen-
sitive function: 

(i) The individual previously per-

formed a safety-sensitive function for 
the employer and the employer is not 
required to pre-employment test the 
individual under paragraphs (a)(1) or (2) 

background image

54 

14 CFR Ch. I (1–1–24 Edition) 

§ 120.109 

of this section before putting the indi-
vidual to work in a safety-sensitive 
function; 

(ii) The employer removed the indi-

vidual from the employer’s random 
testing program conducted under this 
subpart for reasons other than a 
verified positive test result on an FAA- 
mandated drug test or a refusal to sub-
mit to such testing; and 

(iii) The individual will be returning 

to the performance of a safety-sen-
sitive function. 

(5) Before hiring or transferring an 

individual to a safety-sensitive func-
tion, the employer must advise each in-
dividual that the individual will be re-
quired to undergo pre-employment 
testing in accordance with this sub-
part, to determine the presence of a 
prohibited drug in the individual’s sys-
tem. The employer shall provide this 
same notification to each individual 
required by the employer to undergo 
pre-employment testing under para-
graph (a)(4) of this section. 

(b) 

Random drug testing. 

(1) Except as 

provided in paragraphs (b)(2) through 
(b)(4) of this section, the minimum an-
nual percentage rate for random drug 
testing shall be 50 percent of covered 
employees. 

(2) The Administrator’s decision to 

increase or decrease the minimum an-
nual percentage rate for random drug 
testing is based on the reported posi-
tive rate for the entire industry. All in-
formation used for this determination 
is drawn from the statistical reports 
required by § 120.119. In order to ensure 
reliability of the data, the Adminis-
trator considers the quality and com-
pleteness of the reported data, may ob-
tain additional information or reports 
from employers, and may make appro-
priate modifications in calculating the 
industry positive rate. Each year, the 
Administrator will publish in the F

ED

-

ERAL

R

EGISTER

the minimum annual 

percentage rate for random drug test-
ing of covered employees. The new 
minimum annual percentage rate for 
random drug testing will be applicable 
starting January 1 of the calendar year 
following publication. 

(3) When the minimum annual per-

centage rate for random drug testing is 
50 percent, the Administrator may 
lower this rate to 25 percent of all cov-

ered employees if the Administrator 
determines that the data received 
under the reporting requirements of 
this subpart for two consecutive cal-
endar years indicate that the reported 
positive rate is less than 1.0 percent. 

(4) When the minimum annual per-

centage rate for random drug testing is 
25 percent, and the data received under 
the reporting requirements of this sub-
part for any calendar year indicate 
that the reported positive rate is equal 
to or greater than 1.0 percent, the Ad-
ministrator will increase the minimum 
annual percentage rate for random 
drug testing to 50 percent of all covered 
employees. 

(5) The selection of employees for 

random drug testing shall be made by a 
scientifically valid method, such as a 
random-number table or a computer- 
based random number generator that is 
matched with employees’ Social Secu-
rity numbers, payroll identification 
numbers, or other comparable identi-
fying numbers. Under the selection 
process used, each covered employee 
shall have an equal chance of being 
tested each time selections are made. 

(6) As an employer, you must select 

and test a percentage of employees at 
least equal to the minimum annual 
percentage rate each year. 

(i) As an employer, to determine 

whether you have met the minimum 
annual percentage rate, you must di-
vide the number of random testing re-
sults for safety-sensitive employees by 
the average number of safety-sensitive 
employees eligible for random testing. 

(A) To calculate whether you have 

met the annual minimum percentage 
rate, count all random positives, ran-
dom negatives, and random refusals as 
your ‘‘random testing results.’’ 

(B) To calculate the average number 

of safety-sensitive employees eligible 
for random testing throughout the 
year, add the total number of safety- 
sensitive employees eligible for testing 
during each random testing period for 
the year and divide that total by the 
number of random testing periods. 
Only safety-sensitive employees are to 
be in an employer’s random testing 
pool, and all safety-sensitive employ-
ees must be in the random pool. If you 
are an employer conducting random 
testing more often than once per

Federal Aviation Administration, DOT 

§ 120.109 

month (e.g., you select daily, weekly, 
bi-weekly) you do not need to compute 
this total number of safety-sensitive 
employees more than on a once per 
month basis. 

(ii) As an employer, you may use a 

service agent to perform random selec-
tions for you, and your safety-sensitive 
employees may be part of a larger ran-
dom testing pool of safety-sensitive 
employees. However, you must ensure 
that the service agent you use is test-
ing at the appropriate percentage es-
tablished for your industry and that 
only safety-sensitive employees are in 
the random testing pool. For example: 

(A) If the service agent has your em-

ployees in a random testing pool for 
your company alone, you must ensure 
that the testing is conducted at least 
at the minimum annual percentage 
rate under this part. 

(B) If the service agent has your em-

ployees in a random testing pool com-
bined with other FAA-regulated com-
panies, you must ensure that the test-
ing is conducted at least at the min-
imum annual percentage rate under 
this part. 

(C) If the service agent has your em-

ployees in a random testing pool com-
bined with other DOT-regulated com-
panies, you must ensure that the test-
ing is conducted at least at the highest 
rate required for any DOT-regulated 
company in the pool. 

(7) Each employer shall ensure that 

random drug tests conducted under 
this subpart are unannounced and that 
the dates for administering random 
tests are spread reasonably throughout 
the calendar year. 

(8) Each employer shall require that 

each safety-sensitive employee who is 
notified of selection for random drug 
testing proceeds to the collection site 
immediately; provided, however, that 
if the employee is performing a safety- 
sensitive function at the time of the 
notification, the employer shall in-
stead ensure that the employee ceases 
to perform the safety-sensitive func-
tion and proceeds to the collection site 
as soon as possible. 

(9) If a given covered employee is 

subject to random drug testing under 
the drug testing rules of more than one 
DOT agency, the employee shall be 
subject to random drug testing at the 

percentage rate established for the cal-
endar year by the DOT agency regu-
lating more than 50 percent of the em-
ployee’s function. 

(10) If an employer is required to con-

duct random drug testing under the 
drug testing rules of more than one 
DOT agency, the employer may— 

(i) Establish separate pools for ran-

dom selection, with each pool con-
taining the covered employees who are 
subject to testing at the same required 
rate; or 

(ii) Randomly select covered employ-

ees for testing at the highest percent-
age rate established for the calendar 
year by any DOT agency to which the 
employer is subject. 

(11) An employer required to conduct 

random drug testing under the anti- 
drug rules of more than one DOT agen-
cy shall provide each such agency ac-
cess to the employer’s records of ran-
dom drug testing, as determined to be 
necessary by the agency to ensure the 
employer’s compliance with the rule. 

(c) 

Post-accident drug testing. 

Each 

employer shall test each employee who 
performs a safety-sensitive function for 
the presence of a prohibited drug in the 
employee’s system if that employee’s 
performance either contributed to an 
accident or cannot be completely dis-
counted as a contributing factor to the 
accident. The employee shall be tested 
as soon as possible but not later than 
32 hours after the accident. The deci-
sion not to administer a test under this 
section must be based on a determina-
tion, using the best information avail-
able at the time of the determination, 
that the employee’s performance could 
not have contributed to the accident. 
The employee shall submit to post-ac-
cident testing under this section. 

(d) 

Drug testing based on reasonable 

cause. 

Each employer must test each 

employee who performs a safety-sen-
sitive function and who is reasonably 
suspected of having used a prohibited 
drug. The decision to test must be 
based on a reasonable and articulable 
belief that the employee is using a pro-
hibited drug on the basis of specific 
contemporaneous physical, behavioral, 
or performance indicators of probable 
drug use. At least two of the employ-
ee’s supervisors, one of whom is trained 

background image

56 

14 CFR Ch. I (1–1–24 Edition) 

§ 120.111 

in detection of the symptoms of pos-
sible drug use, must substantiate and 
concur in the decision to test an em-
ployee who is reasonably suspected of 
drug use; except that in the case of an 
employer, other than a part 121 certifi-
cate holder, who employs 50 or fewer 
employees who perform safety-sen-
sitive functions, one supervisor who is 
trained in detection of symptoms of 
possible drug use must substantiate 
the decision to test an employee who is 
reasonably suspected of drug use. 

(e) 

Return to duty drug testing. 

Each 

employer shall ensure that before an 
individual is returned to duty to per-
form a safety-sensitive function after 
refusing to submit to a drug test re-
quired by this subpart or receiving a 
verified positive drug test result on a 
test conducted under this subpart the 
individual shall undergo a return-to- 
duty drug test. No employer shall 
allow an individual required to undergo 
return-to-duty testing to perform a 
safety-sensitive function unless the 
employer has received a verified nega-
tive drug test result for the individual. 
The test cannot occur until after the 
SAP has determined that the employee 
has successfully complied with the pre-
scribed education and/or treatment. 

(f) 

Follow-up drug testing. 

(1) Each 

employer shall implement a reasonable 
program of unannounced testing of 
each individual who has been hired to 
perform or who has been returned to 
the performance of a safety-sensitive 
function after refusing to submit to a 
drug test required by this subpart or 
receiving a verified positive drug test 
result on a test conducted under this 
subpart. 

(2) The number and frequency of such 

testing shall be determined by the em-
ployer’s Substance Abuse Professional 
conducted in accordance with the pro-
visions of 49 CFR part 40, but shall con-
sist of at least six tests in the first 12 
months following the employee’s re-
turn to duty. 

(3) The employer must direct the em-

ployee to undergo testing for alcohol in 
accordance with subpart F of this part, 
in addition to drugs, if the Substance 
Abuse Professional determines that al-
cohol testing is necessary for the par-
ticular employee. Any such alcohol 
testing shall be conducted in accord-

ance with the provisions of 49 CFR part 
40. 

(4) Follow-up testing shall not exceed 

60 months after the date the individual 
begins to perform or returns to the per-
formance of a safety-sensitive func-
tion. The Substance Abuse Professional 
may terminate the requirement for fol-
low-up testing at any time after the 
first six tests have been conducted, if 
the Substance Abuse Professional de-
termines that such testing is no longer 
necessary.

§ 120.111 Administrative and other 

matters. 

(a) 

MRO record retention requirements. 

(1) Records concerning drug tests con-
firmed positive by the laboratory shall 
be maintained by the MRO for 5 years. 
Such records include the MRO copies of 
the custody and control form, medical 
interviews, documentation of the basis 
for verifying as negative test results 
confirmed as positive by the labora-
tory, any other documentation con-
cerning the MRO’s verification process. 

(2) Should the employer change 

MRO’s for any reason, the employer 
shall ensure that the former MRO for-
wards all records maintained pursuant 
to this rule to the new MRO within ten 
working days of receiving notice from 
the employer of the new MRO’s name 
and address. 

(3) Any employer obtaining MRO 

services by contract, including a con-
tract through a C/TPA, shall ensure 
that the contract includes a record-
keeping provision that is consistent 
with this paragraph, including require-
ments for transferring records to a new 
MRO. 

(b) 

Access to records. 

The employer 

and the MRO shall permit the Adminis-
trator or the Administrator’s rep-
resentative to examine records re-
quired to be kept under this subpart 
and 49 CFR part 40. The Administrator 
or the Administrator’s representative 
may require that all records main-
tained by the service agent for the em-
ployer must be produced at the em-
ployer’s place of business. 

(c) 

Release of drug testing information. 

An employer shall release information
