Special issuance of medical certificates
Read the official ruleIf you don't meet the standard medical requirements, the Federal Air Surgeon can grant a Special Issuance Authorization allowing you to hold a medical certificate for a specified period. You must demonstrate that you can safely perform pilot duties despite your condition. These authorizations expire and require renewal.
Alternatively, for static or nonprogressive conditions, you may receive a Statement of Demonstrated Ability (SODA), which doesn't expire. With a SODA, an aviation medical examiner can issue your medical certificate if your condition hasn't worsened.
The Federal Air Surgeon may require special flight tests, impose operational limitations, or mandate periodic medical evaluations. For third-class medicals, the FAA considers that private pilots accept personal risks that wouldn't be acceptable for commercial operations.
Authorizations and SODAs can be withdrawn if your condition worsens, you fail to comply with limitations, or public safety is endangered. You have 60 days to request review of any withdrawal decision.
