Read the official rule

The guidance emphasizes the strict regulation of psychoactive substance use, specifically alcohol and drugs, for pilots and aircrew to ensure aviation safety. Pilots must adhere to testing protocols before employment, following incidents, and if there is suspicion of substance influence, promoting a culture of responsibility and self-discipline regarding substance use. Any confirmed positive results lead to immediate removal from safety-sensitive duties and requisite rehabilitation procedures before returning to flying roles.

Key points

  • Psychoactive substances include drugs and alcohol, which must be avoided by aircrew.
  • Testing for substance use is required at several key points: pre-employment, post-incident, and random checks.
  • Employers and employees share the responsibility to uphold aviation safety by adhering to substance regulations.
