The 1959 medical standard
The FAA adopted regulatory language treating any diabetes requiring insulin or another hypoglycemic drug as potentially disqualifying. At the time, treatment options were limited and the agency had little data on how diabetics performed as pilots.
Diabetics needed individual waivers from FAA medical staff to fly.
Created a 67-year-old framework that medical practice far outpaced. Modern treatments like metformin, GLP-1 agonists, and SGLT2 inhibitors now control most type 2 diabetes without insulin.
The exact regulatory language from 1959 is what the September 2026 proposal would change.
