straight from the AME handbook.
AASI for Renal Calculi
AME Assisted Special Issuance (AASI) is a process that provides 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.
An 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 application for an AASI for the above
disease/condition, and the applicant has all 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.
AMEs 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 the 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.
