United States Air Force (USAF) Airworthiness Bulletin (AWB)-516
Subject: Change Notices for MIL-HDBK-516, Airworthiness Critieria
Attachments: (1) Glossary of References and Supporting Information
(2) Change Notice Development Process
(3) AWB-516 Change Notice Format
1. Purpose: This bulletin directs Chief Engineers to assess new and changed designs against
the current MIL-HDBK-516, including all Technical Airworthiness Authority (TAA)
approved Change Notices (CN), when creating certification basis (CB) documents. CNs will
be maintained on the USAF Airworthiness SharePoint site to include new or revised MIL-
HDBK-516 Criterion, Standards, or Methods of compliance (CSM) per examples in
Attachment (3).
2. Office of Primary Responsibility: USAF AIRWORTHINESS OFFICE. Comments,
suggestions, or questions on this bulletin should be emailed to the USAF
AIRWORTHINESS OFFICE Mailbox (USAF.AIRWORTHINESS.OFFICE@us.af.mil).
3. Background: Revision of MIL-HDBK-516 typically takes several years. In the interim,
new or revised CSM will be approved via CNs and published IAW Attachment (2).
4. TAA Guidance: Approved CNs will be considered as part of the current published version
of MIL-HDBK-516 for all USAF development and modification efforts. Any CB that is
prepared must include all approved CNs, if applicable, to the design under consideration.
Tailoring to create the CB will be consistent with AWB-004, Development of an
Airworthiness Certification Basis, as modified by the following:
a) The CB must be developed prior to release of any development acquisition packages
(e.g., Request for Proposal (RFP)).
b) For new aircraft designs and reportable modifications, the Chief Engineer/Delegated
Technical Authority (CE/DTA) will, IAW existing policy, obtain TAA approval of the
exact version of MIL-HDBK-516 and CN(s) to be used for developing the CB.
