AME Assisted Special Issuance (AASI) is a process that provides Examiners 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 issuance of an Authorization for the above disease/condition, and the applicant has all of the requisite medical information necessary for a determination, the Examiner must defer and submit all of the documentation to the AMCD or RFS for the initial determination.
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 summary of the applicant’s medical condition since the last FAA medical examination, including a statement regarding any further episodes of DVT, PE or other complication of hypercoagulopathy (see below *);
- The name and dosage of medication(s) used for treatment and/or prevention with comment regarding side effects; and
- A minimum of monthly International Normalized Ratio (INR) results for the immediate prior 6 months (see below *).
- More than 20 percent of INR values are <2.0 or >3.0; or
- The applicant develops emboli, thrombosis, bleeding, or any other cardiac or neurologic condition previously not diagnosed or reported.
