Yes, the FAA performs a rigorous check of your medical history every time you apply for or renew an Airman Medical Certificate. Before meeting with an Aviation Medical Examiner (AME), you must fill out a "MedXPress" application where you are legally required to disclose all past and present medical conditions, hospitalizations, surgeries, and medications. The FAA specifically looks for a history of cardiovascular issues (like heart attacks), neurological disorders (like epilepsy), and mental health conditions (like depression or ADHD). In 2026, the FAA has a direct data-sharing link with the National Driver Register, allowing them to cross-reference your medical application with any DUI or substance-abuse-related driving offenses. Falsifying or omitting any part of your medical history is a federal crime that leads to the immediate revocation of all pilot certificates and can result in significant fines or imprisonment. It is always better to report a condition and seek a "Special Issuance" (waiver) than to hide it.
