What Happens When Sleep Apnea Comes Up During an Existing FAA Deferral

You are already deferred. The FAA has your file for an issue that is unrelated to sleep, and your focus is on assembling the complete package to send to Oklahoma City. Then a sleep study gets added to the list. For most pilots this is where confusion sets in. Is this a new deferral? A separate process? Something that could ground you longer?

If you are already deferred for another medical issue, the sleep-study results become part of your existing FAA review. Any additional requirements depend on the findings and your case. Below is a walk-through of what the FAA looks for, how the AHI number drives the path forward, and the role each party (ESD, your treating physician, your AME, and the FAA) plays.

What the Complete Package Typically Includes

Start with the FAA request or deferral letter for your case. Gather the requested medical records, the sleep-study results and interpretive report, and any assessment or treatment documentation that applies. The sleep-related records become part of the package for your existing FAA review. The FAA OSA Protocol and current OSA Treated Status Report explain the sleep-apnea requirements. [1] [2]

Use the documentation route that fits your situation. A first assessment for suspected OSA is different from documenting diagnosed and treated OSA. For diagnosed and treated OSA, the FAA pilot FAQ provides these alternatives:

A completed and signed OSA Treated Status Report; OR a detailed clinical progress note addressing every item on that form, a signed FAA Compliance with Treatment form or equivalent, the results and interpretive report of the most recent sleep study, and the most recent PAP download covering 30 days or longer, where applicable to PAP treatment. [4]

For a requested diagnostic study, gather the results and the sleep medicine specialist’s interpretation, including the diagnosis and any treatment recommendations. FAA Specification Sheet B describes a Type I laboratory study or a Type II (7-channel) unattended home study providing comparable data and standards. Follow the study requirements specified for your case. [3]

If you are on PAP therapy, a PAP download showing actual time used, not an insurance-format report. The FAA has been explicit that insurance-style reports (which only show whether use is above or below 4 hours) do not satisfy their requirements. [4] [5]
If you have already been on an Authorization for Special Issuance for OSA, that letter and the renewal items described in the AASI for Sleep Apnea/OSA. [5]

How Your AHI Drives the Next Steps

When you receive your report, identify whether the AHI is from the initial study before treatment or a study performed during treatment. Keep that report with your assessment and any treatment records. The FAA considers symptoms and treatment effectiveness alongside the AHI; the number alone does not determine the submission requirements. [2] [3] [6]

Here is how the published FAA guidance addresses the broad ranges:

AHI Under 5

Gather the assessment report and any sleep-study results requested by the FAA, even if the assessment is negative. Your treating physician interprets an initial untreated AHI under 5 in the context of the full evaluation. A negative sleep study does not by itself resolve your deferral for another condition; the FAA still needs the records requested for the overall case. [3] [8]

AHI 5 to 10

Gather the assessment and sleep-study report, then add treatment records if treatment has been prescribed and the FAA requests them. For an initial untreated AHI between 5 and 10, there is no separate checklist in the cited FAA guidance based on that range alone. Sheet B describes the assessment and study information; Sheet A describes records after prior assessment or treatment. Use the FAA request for your case to determine which documents to submit. [3] [6]

AHI Over 10

Gather the diagnostic report showing your initial untreated AHI, plus the applicable treatment documentation. The FAA Treated Status Report requires PAP for an initial untreated AHI of 15 or higher. An AHI over 10 does not put every pilot in that category. For lower initial untreated results, confirm the applicable treatment and documentation requirements with your treating physician and AME. [2]

If you are prescribed PAP, gather the treatment report and a device download showing actual usage. The FAA pilot FAQ specifies a minimum of 30 days of actual PAP usage data for an initial special issuance request and the last 12 months for renewal. The FAA benchmark is use on at least 75 percent of nights, an average of at least 6 hours per night, and a treated AHI of 5 or less. These requirements apply to PAP treatment, rather than every initial AHI over 10. [2] [4]

Treatment Scenarios

The FAA accepts a range of treatments for OSA, not only PAP. The published guidance addresses what documentation is expected for each, but the sufficiency of any specific package depends on the individual pilot’s clinical picture. [2] [5]

Dental Device

Gather the sleep-study report and a completed OSA Treated Status Report, or a detailed clinical progress note addressing every item on that form, along with the additional records requested for your case. If you use a dental device and your AHI is around 7, identify whether that result was measured before treatment or while using the device. The FAA form calls for effective, well-tolerated treatment, daily dental-device use and no symptoms. A generic doctor’s note does not provide all of that information, and the AHI alone does not establish whether the package is sufficient. [2] [6]

If you already hold an OSA authorization, check its instructions and the AASI renewal requirements before submitting your records. The dental-device renewal route also addresses conditions such as atrial fibrillation, diabetes and hypertension treated with more than two medications. Separately, AASM and AADSM recommend follow-up sleep testing to confirm oral-appliance effectiveness. Clinical follow-up and FAA documentation serve different purposes; neither makes an AHI of 7 a guarantee of certification. [5] [7]

AHI 23 Before or During Treatment

Start with the report showing the AHI of 23 and identify whether it is an initial untreated result or a result during treatment. If it is untreated, gather the applicable PAP treatment documentation described above because it exceeds the FAA threshold requiring PAP. If it was measured during treatment, gather the treatment records and have your treating physician assess the result: it exceeds the Treated Status Report benchmark of 5 or less. That form directs the AME to defer or contact FAA Aerospace Medicine when there are negative answers or concerns. The number alone does not establish the complete submission or the certification outcome. [2] [8]

Your treating physician manages any reassessment of treatment. For a pilot already deferred for another condition, the FAA must also consider the other medical information in the case. [8]

Who Does What in This Process

One of the clearest ways to reduce confusion is to understand which party owns which part of the pathway:

ESD provides the Type II at-home sleep study: a 7-channel diagnostic test interpreted by a board-certified sleep medicine specialist. ESD does not practice medicine, manage treatment, or make certification predictions.
Your treating physician manages your diagnosis and treatment, completes clinical reports, and signs off on the OSA Treated Status Report when appropriate. [2]
Your AME performs the FAA exam, reviews your documentation at the exam, and either issues your medical certificate or defers to the FAA. Your AME is also the one who uploads your documents to the FAA system. [1] [3] [6]
FAA medical certification authorities review deferred cases and decide whether to grant an Authorization for Special Issuance under 14 CFR 67.401. That authority is exercised by the Federal Air Surgeon, the Manager of the Aeromedical Certification Division and Regional Flight Surgeons. [8]

For a pilot already deferred for another condition, the sleep study documentation gets added to the overall file. It is considered alongside the other medical information in your case.

How ESD Fits In

At ESD, our role in this process is specific: we provide the Type II home sleep study in the format the FAA expects, interpreted by a board-certified sleep medicine specialist, delivered in a report that your treating physician and AME can use. We do not make certification predictions, substitute for your treating physician, or interpret the FAA’s decision on your overall case.

If you are already deferred and have been told you need a sleep study as part of your package, the goal is to get a complete, properly formatted study the first time, so your overall file keeps moving forward. That is what we are built for.

If you have questions about whether a Type II study fits your situation, reach out. We are happy to help you understand what the test involves and how it fits into the broader documentation the FAA is looking for.
