Hi I copied this info from the AOPA medical info site. It is only available to AOPA members but here it is
Diabetes Specifications
Initial and Follow-up
Pilots with a diagnosis of diabetes mellitus controlled by diet alone are considered eligible for medical certification under the revised Part 67 medical standards. Medical documentation as described below is required at the time of examination. The aviation medical examiner may issue a certificate to applicants with this history, provided the necessary documentation is provided, and they are otherwise qualified. Applicants who report using oral medications may not be issued a certificate by the aviation medical examiner. After initial clearance, the FAA may authorize the examiner to issue future certificates, as long as there are no significant adverse changes noted on the follow up reports.
Applicants who are controlling diabetes by diet or with oral medications, including glucophage (metformin), or precose (acarbose) will be expected to demonstrate for 60 days evidence of adequate control, stabilization, and no evidence of adverse side effects or complications from medication.
After the 60 day control period is completed, and within the next 30 days, a glycosolated hemoglobin (A1C) should be done. Normal laboratory values for A1C hemoglobin will range from about 4.0%-7.5%. The FAA will allow up to 9%.
There should also be no evidence of significant medical or surgical complications, including cardiac, peripheral vascular, renal, neurological, or ophthalmologic disease.
No beta-adrenergic blocking antihypertensive agents should be used. These medications may increase blood glucose.
Minimum requirements for follow up evaluation will vary with the class of medical certificate held. 1st and 2nd Class certificate holders will usually be required to submit follow up evaluations annually. 3rd Class holders will submit evaluations at the time of their regular FAA medical renewal. Individual cases may require more frequent evaluations based on case history.
Note: Express mail will usually expedite the delivery of your records to the FAA. If you choose to use overnight delivery, the correct address is:
