The FAA sent out an email in June saying the following:

On July 18^th 2022, the FAA will be decommissioning the following databases housed on the Regulatory Guidance Library (RGL):

• Special Airworthiness Information Bulletins (SAIB)
  • SAIB documents will change their naming convention from AIR-YY-## to YYYY-##
• Airworthiness Directives: Notices of Proposed Rulemaking (AD NPRM)

After this date, SAIB and AD NPRM documents will only be available on the newly developed Dynamic Regulatory System (DRS). In our next communication, we will provide guides with detailed instructions on how to locate SAIB and AD NPRMs in DRS. In the meantime, please use the DRS Help & Training page for information. Please use the “DRS Feedback” button for any questions or issues you may encounter.

Users may subscribe to receive notifications about published SAIBs by navigating to the FAA GovDelivery Service and selecting any applicable categories. Any notification subscriptions you already have will continue without any needed action.

Best Regards,

The DRS Development Team
