Drug and alcohol testing compliance is a key oversight area for the FAA and DOT, as it directly affects safety-sensitive roles such as pilots, mechanics, dispatchers, and other operational staff. As such, airlines must run a DOT-regulated testing program that includes the following components:
- Random testing: Employees are selected through a random process at required annual rates, with testing spread across the year so it’s unpredictable.
- Pre-employment testing: New hires in safety-sensitive roles generally must test negative before performing covered duties.
- Reasonable suspicion testing: Triggered when trained supervisors observe specific behavior or signs consistent with impairment.
- Post-accident testing: Required after certain accidents/incidents, based on DOT criteria (severity and role), with time windows for alcohol and drug tests.
- Return-to-duty & follow-up testing: For employees who violated policy and are cleared to return, including a schedule of follow-up tests set by a substance-abuse professional process.
- Recordkeeping & audits: Airlines must maintain detailed documentation—test results, chain-of-custody, training records, vendor/collector credentials, and annual reporting—often with multi-year retention requirements.
- Vendor oversight: If a third party administers testing, the airline is still responsible for ensuring the vendor follows DOT procedures and that records are complete and accessible.
