Changed the words "Safety and Mission Assurance Program" to "Safety and Mission Assurance Plan" in paragraphs 2.2.2 Note, 2.2.3 note 3, 2.2.4, 2.2.4 note 1, and in the table under paragraph D.3 in Appendix D, and added a reference to IV&V in paragraph 2.2.4.

The release of the NASA-STD-8719.29, NASA Technical Requirements for Human-Rating, was a direct transfer of the technical requirements from NPR 8705.2C, Change 1 chapter 3, and did not introduce any new requirements or changes to existing requirements. This update deletes the contents of the previous chapter 3 to address conformity with NPR 1400.1, NASA Directives and Charters Procedural Requirements, which mandates the exclusion of technical requirements in NASA directives.

Editorial references to the technical requirements in NASA-STD-8719.29 are added in the following sections of this NPR:

- P.2 Applicability, Note 3.

- P.4 Applicable Documents

- Introduction, section 1.1.3

- Overview of the Human-Rating Certification Process, section 1.3.c

- Roles and Responsibilities, section 1.4.8.c

- Process and Standards, sections 2.2.2 and 2.2.5

- Designing the System, sections 2.3.2, 2.3.5, 2.3.7.1.b, and 2.3.7.1.e

- Verifying and Validating the System Capabilities and Performance, section 2.4.1

Additionally, Note 2 of section 2.3.7.2 and Appendix C have been corrected to refer the reader to ISO 11231:2019 and NASA/SP-2011-3421 for guidance on probabilistic risk assessment in lieu of the cancelled NPR 8705.5.
