The John A. Hauser Mental Health in Aviation Act directs the Federal Aviation Administration to reform how it handles mental health disclosures from pilots and air traffic controllers, aiming to reduce the stigma that discourages these workers from seeking help. Within 18 months, the FAA must update its medical certification regulations to encourage self-reporting of mental health conditions, and it must periodically review and improve the special issuance process that allows pilots and controllers with mental health diagnoses to remain certified to work. The bill also requires the FAA to implement recommendations from a 2024 rulemaking committee on mental health and medical clearances, expand training for aviation medical examiners, and address staffing backlogs, backed by up to $15 million per year from 2026 through 2028. Additionally, the FAA must launch a public information campaign from 2026 to 2028 to destigmatize mental health care in the aviation industry and make support resources more accessible to pilots and controllers. Throughout the process, the agency must consult with industry stakeholders, unions, and medical experts, and report to Congress on its progress and any decisions not to adopt recommended changes.
