FAA OSA Specification Sheet B: Assessment Request

The FAA sends Sheet B when a pilot's risk factors suggest obstructive sleep apnea. Within 90 days the pilot needs a current OSA assessment based on American Academy of Sleep Medicine criteria and, if a sleep study is needed, an interpreted study with diagnosis and treatment recommendations. A positive study suspends use of the medical certificate until treatment is documented.

Who completes it

The AME, the pilot's personal physician or a sleep medicine specialist performs the AASM-based assessment. A sleep medicine specialist must interpret any sleep study, and the treating physician completes the OSA Treated Status Report if OSA is diagnosed.

Submitting and payment

How to submit it
The pilot gives the assessment, any sleep study report and treatment documents to the AME for upload into the FAA file, for review by AMCD or the Regional Flight Surgeon's office within 90 days.

Good to know

  • Accepted studies are a Type I laboratory polysomnogram or a Type II (7-channel) unattended home sleep test; a Level III home test is accepted where Level II testing is unavailable.
  • A positive home test needs no further testing, but an equivocal one needs a higher-level study unless a sleep medicine specialist documents why no further study is necessary.
  • If no sleep disorder is diagnosed, the pilot may keep using the medical certificate, but the evaluation report and any study results must still be sent to the FAA.
  • Sheet B was updated 05/27/2026. Once OSA is diagnosed and treated, Specification Sheet A and the OSA Treated Status Report apply.
