AME Assisted - All Classes
Kidney Stones (Renal Calculi)
Examiners may re-issue an airman medical certificate under the provisions of an Authorization, if the applicant provides the following:
- An Authorization granted by the FAA;
- A statement from your treating physician regarding the location of the retained stone(s), estimation as to size of stone, and likelihood of becoming symptomatic; and
- A current report of appropriate imaging study (IVP, KUB, Ultrasound, or Spiral CT Scan) and provide a metabolic work-up, both performed within last 90 days.
The AME must defer to the AMCD or Region if:
- If the treating physician comments that the current stone has a likelihood of becoming symptomatic;
- If the retained stone(s) has moved when compared to previous evaluations; or
- If the stone(s) has become larger when compared to previous evaluations.
AME Assisted Special Issuance (AASI) is a process whereby the FAA delegates to AMEs the ability to re-issue an airman medical
certificate under the provisions of an Authorization for Special Issuance of a Medical Certificate (Authorization) to
an applicant who has a medical condition that is disqualifying under Title 14 of the Code of Federal Regulations (14 CFR) part 67.
A staff FAA physician provides the initial certification decision and grants the Authorization in accordance
with 14 CFR § 67.401.
The Authorization letter is accompanied by attachments that specify the information that treating physician(s) must
provide for the re-issuance determination. If this is a first time issuance of an Authorization for the
disease/condition, and the applicant has all of the requisite medical information necessary for a determination,
the AME must defer and submit all of the documentation to the AMCD or RFS for the initial determination.
