Summary

The Question

Is random DOT drug and alcohol testing after a pilot's last flight of the day part of the flight duty period or the rest period under 14 CFR part 117?

Background

Allegiant Travel Company described a pilot who, after a 6-hour flight duty period, is told on arrival to report for random drug or alcohol testing within 60 minutes, with the next flight 18 hours later.

The FAA’s Interpretation

Neither. Testing after flying has ended is not part of the flight duty period under 14 CFR part 117 because no further flying was assigned, and it is not part of the rest period because the pilot is not free from all restraint by the certificate holder. This does not apply to random testing before or between flight segments.

Re: Interpretation on Whether Drng and Alcohol Testing is Flight Duty Time under
part 117
Dear Mr. Bonner:

This is in response to your email message dated December 17, 2014 requesting an interpretation of whether required Department of Transportation (DOT) drug and alcohol testing is considered "duty time" under 14 Code of Federal Regulations (14 CFR) part 117 - Flight and Duty Limitations and Rest Requirements: Flightcrew Members. This interpretation applies to all prut 121 certificate holders conducting passenger-carrying operations and any part 121 certificate holders opting to apply the limits of part 117 to its all-cargo operations.

In the scenario presented in your email, a pilot returns from a 6 hour day, is met at the aircraft and informed that he/she has been randomly selected for drug and/or alcohol testing, and has 60 minutes to report to the drug testing facility. For purposes of this interpretation, we will assume that the 6 hours is the pilot's "flight duty period." The pilot is done flying for the day but has a flight scheduled the next day, 18 hours from the time he finishes his flight duty period. You ask whether the time the pilot spends driving to the testing facility, having the test perfonned, and then driving home is considered duty time. Title 14 C.F.R. part 117 applies only to part 121 operations, and defines the terms flight duty period and rest period. The flight duty period, "begins when a flightcrew member is required to report for duty with the intention of conducting a flight, and ends when the aircraft is parked after the last flight. .." Rest period is defined as, "a continuous period during which the flightcrew member is free from all restraint by the certificate holder. .." Considering the circumstances outlined in your request, looking at the part 117 definitions cited above, it is clear that the random drug and alcohol testing outlined in your scenario is not part of the flight duty period, because the flightcrew members were not assigned any additional flying to be conducted at the conclusion of at random drng and alcohol testing. It clearly cannot be prut of the rest period, because the flightcrew member is not "free from all restraint by the certificate holder." Thus, the FAA considers drug and alcohol testing

conducted after flying has been concluded to be neither part of the flight duty period under part 117 nor part of the rest period. 1 \ We trust that this response has been helpful to you. If you have fuither questions or need additional information, please do not hesitate to contact my staff at (202) 267-3073. This response was prepared by Neal O' Hara, an attomey in the Office of the Chief Counsel, Regulations Division, and coordinated with the Air Transportation Division of the Flight Standards Service.

1 This would not apply to random drug and/or alcohol testing prior to or between fligh t segments.
