You can’t. Some special issuances have progressive things jb their requiring compliance throughout the SI. And without compliance they withdraw the SI and you are then denied. So no - you can’t go right when you get it for some, you have to comply with the SI and let it expire.
yes there are several that require continued compliance to continue to hold the si during its validity. But you also bring up a certain clause - that you can also get basic med right after. And operate on basic med. HOWEVER the si can be cancelled with failed compliance during its validity and then the basic med immediately also becomes invalid
are you saying there are SI’s where some type of compliance is required before the NVA date on the certificate? I’ve never seen that, I can’t imagine AMCD having a pilot on the honor system for providing a report. I’m thinking of the expiration of the actual certificate, not the expiration on the SI (which could be 2-3-4 years down the road). If you’re on SI / AASI and just let your certificate expire, I don’t think you’ll get a denial for not keeping with the requirements of the SI letter. That seems like it would defeat the purpose of BM for most pilots who are on it?

I think that's the correct interpretation.As I understand, you can apply for and obtain your Basic Med while still under a SI, but, you must fulfill the requirements of the current SI until it expires. At that point you continue flying under BM. In other words, you do not have to wait until the SI expires to obtain BM, but you are still flying under the SI until all obligations met and it expires.
I tried to quote you but site wouldn’t allow since I’m new
I watched that Reddit thread when it popped up, just looked at it again. Re the epilepsy, last seizure was 17 yrs previous and he had been off meds since 2012. OP said the autism was NBD. Did his Class 3 Jan 22, got his SI / C3 Mar 23 with NVA Jan 24. OP said to reup his Class 3 in January for another 12 months all he needs is the report from neuro, nothing regarding the ASD. His next Class 3 is due Jan 2027 but he will do BM if the SI becomes too costly or time consuming. I didn’t see the therapist requirement, but I didn’t read his personal blog either.
this was not the discussion. The discussion was when the medical was valid - and to immediately go to basic med (while the medical with SI was valid ) and as I and others have confirmed - they can pull it if you don’t comply with the si terms if it’s ongoing.
Exactly and all true. But as I pointed out - this is NOT the discussion from above. The discussion is they get an SI and do not finish complying with the SI and go straight to basicmed. What people are not getting is that /Some/ SI’s have continuing conditions during the validity of the SI. And those must be followed or the si medical can be revoked. You can state that it can’t be revoked after expiration which I agree with. But the argument above was that someone could go immediately to bm and not have to worry about revocation while the SI was valid - which isn’t the case. I never said what you said wasn’t true. Just didn’t apply to the current question that was asked
But people don’t realize that some SI had continuing requirements to stay valid.

Yes, he does. He has already won the necessary SI via HIMS.So I'm just curious to know how the FAA deals with an SI related to one of the disqualifying conditions for Basic Med vs. an SI related to a condition that would NOT disqualify someone from operating under Basic Med. Sleep apnea, for instance, is not listed as disqualifying for Basic Med, and presumably it is up to the evaluating physician to make the determination. On the other hand does an airman with a prior mental health disorder who required HIMS involvement to obtain a Special Issuance have the same option to let it expire and then seek a Basic Med pathway?

Yes they do, but limited to certain conditions.

I'm not sure how what conditions are limited in that explanation. Why the use of the term "One SI" on the FAA website information pages?

If you hold a special issuance medical certificate for a condition that is not listed, ...... you are ineligible to fly under BasicMed.
No, no, no! 100% incorrect. It’s exactly the opposite. Those are the only conditions that require a 1-time SI. If you have held a medical and subsequently develop some unlisted condition (sleep apnea, for example), you can go to Basic Med without getting an SI first. If you have an SI medical for sleep apnea (or some other unlisted condition) you are free to let it expire and use Basic Med.
That’s why so many of us have switched to Basic.
I corrected my post above.
No, your last sentence in that post is incorrect.
This:
is simply untrue.If you hold a special issuance medical certificate for a condition that is not listed, ...... you are ineligible to fly under BasicMed.
We may be doing a bit of apples and oranges here. There seems to be confusion over the reach of the Domingo memo. So let's be somewhat specific and see what our medical experts (@bbchien @lbfjrmd @WingmanMed) say about this scenario.
May the pilot turn to BasicMed?
- In January 2020, the pilot receives a HIMS-based SI authorization and 3rd class certificate. The SI Authorization has HIMS compliance conditions.
- The SI authorization expires October 31, 2026
- The initial third class medical expires March 31, 2020.
- The pilot has complied with the conditions of the SI and obtains a second medical certificate which expires September 30, 2020.
- The pilot decides the program is too expensive and allows the current third class medical to expire. Doesn't go back to an AME to renew.
- After the current third class medical expires, the pilot ceases participation in the program. FAA withdraws the SI authorization for non-compliance.
Authorizations often have a longer duration than the associated special issuance medical certificate. These longer durations are for internal FAA administrative purposes and aid the Office of Aerospace Medicine with the processing of special issuance medical certificates under 67.401. The Authorization's longer duration period conveys no independent medical privilege as evidenced by the requirement for an airman to demonstrate that he remains qualified for a new special issuance medical certificate when the current special issuance medical certificate expires. As such, an airman's responsibility to comply with the terms of an unexpired Authorization - including a term that requires regular submission of medical information - terminates when the associated special issuance medical certificate expires. Because there is no reasonable basis for requiring an airman in those circumstances to provide medical information that is not needed for determining medical certification under 67.401, the FAA would not have a basis to withdraw the Authorization.
