Chapter 1: Responsibilities

1.1 The NASA Associate Administrator for Space Flight (AA for OSF) shall:

a. Act as the Human-Rating Authority for all human space flight systems and shall certify each space flight system as human-rated (Requirement 30670).

b. Charter and direct a Human-Rating Independent Review Team (HRIRT) for human space flight systems, such as Earth-to-Orbit (ETO) vehicles, space stations, or vehicle level programs (Requirement 30671). The review team shall be composed of nonadvocate members who perform all functions independent of the program manager's control (Requirement 30672).

c. Ensure that the human-rating plan, developed by the programs/projects, is provided to the AA for SMA and the CHMO for review and concurrence (Requirement 30673).

d. With the recommendation of the AA for SMA, CHMO, and the HRIRT, review and approve the human-rating plan for all proposed space flight systems, including changes and implementation (Requirement 30674). This includes any tailoring or deviations.

e. Oversee the proper development and execution of the human-rating plan for OSF-managed programs (Requirement 30675).

f. Verify continued compliance with human-rating certification requirements (Requirement 30676).

1.2 The NASA Associate Administrator for Safety and Mission Assurance (AA for SMA) shall:

a. Review the human-rating plan for all proposed space flight systems, including changes and implementation, and concur or nonconcur on the plan (Requirement 30678).

b. Concur or nonconcur on all human-rating requirements tailoring and deviations to the human-rating plan (Requirement 30679).

c. Provide input to the HRIRT charter (Requirement 30680).

d. Review the HRIRT assessments and provide concurrence or nonconcurrence to the GPMC and to the NASA Administrator (Requirement 30681).

e. Concur or nonconcur on the NASA AA for OSF certification of any space flight system to be human-inhabited during any phase of flight (Requirement 30682).

f. Maintain and update the "Human-Rating Requirements and Guidelines for Space Flight Systems" NPG and verify that processes are in place to ensure compliance with the document (Requirement 30683).

1.3 The NASA Chief Health and Medical Officer (CHMO) shall:

a. Review the human-rating plan for all proposed space flight systems, including changes and implementation, and concur or nonconcur on the plan (Requirement 30685).

b. Concur or nonconcur on all human-rating requirements tailoring and deviations to the human-rating plan (Requirement 30686).

c. Provide input to the HRIRT charter and membership (Requirement 30687).

d. Review the HRIRT assessments and provide concurrence or nonconcurrence to the GPMC and to the NASA Administrator (Requirement 30688).

1.4 The NASA Associate Administrator for Exploration Systems shall:

a. Oversee the proper development and execution of the human-rating plan for the Office of Exploration Systems-managed programs (Requirement 30690).

b. Ensure the human-rating plan, developed by programs/projects, is provided to the AA for SMA and the CHMO for review and concurrence (Requirement 30691).

c. Ensure all space flight systems design, development, testing, and evaluation are performed to meet customer requirements prior to transfer to the OSF for space flight system operations (Requirement 90692).

1.5 The Program Manager shall:

a. Develop the human-rating plan for all human space flight program activities, based upon the unique mission goals, technical and operational risk, other risk-management plan requirements, and other specific characteristics of the program (Requirement 30694).

b. Integrate the human-rating plan into overall program management planning and execution and decisionmaking processes, including cost, schedule, performance, and other programmatic risks consistent with NPR 7120.5, latest revision (Requirement 30695).

c. Obtain approval of the program's human-rating plan by the AA for OSF, the AA for SMA, and the CHMO during the program approval process (Requirement 30696).

d. Justify proposed tailoring and deviations from these requirements (Requirement 30697). Tailoring and deviations may be implemented by the program manager where sound technical rationale provides justification and it is demonstrated that the tailoring and deviations do not significantly increase risk to human occupants. The tailoring and deviations shall be documented in the program human-rating plan, approved by the AA for OSF and are subject to the concurrence from the AA for SMA and CHMO (Requirement 30698).

e. Ensure that all deviations and waivers generated after the program human-rating plan approval from NASA Headquarters are presented at all program major milestone reviews (Requirement 30699).

f. Ensure that compliance and verification processes have clear traceability with all functional and performance design requirements established in this document (Requirement 30700).

g. Ensure that issues, problems, and decisions regarding the specification and achievement of human rating are elevated to appropriate management levels using a formal management review process, with an emphasis on risk management (Requirement 30701).

h. Establish and utilize a continuous tracking method for documenting and sustaining compliance with all human-rating requirements after initial human-rating certification (Requirement 30702).

i. Use systems engineering, safety, health, and management approaches in which all aspects of design, development, fabrication, operations, maintenance, and disposal are considered in the human-rating process (Requirement 30703). This should be accomplished by utilization of tools such as failure modes and effects analyses, fault trees, hazard analyses, maintainability analyses, reliability predictions, human error analysis, and probabilistic risk assessments to identify, quantify, mitigate, and manage hazards.

j. Demonstrate program compliance with the approved human-rating and verification plans to ensure the flight system certification is achieved and maintained (Requirement 30695).

k. Ensure that all records generated in the process of complying with this document are managed and dispositioned in accordance with NPR 1441.1, NASA Records Retention Schedules, latest revision (Requirement 30706).

l. Ensure that all performance data are archived to be available for recertification of program human rating (Requirement 30707).

1.6 The Human-Rating Independent Review Team (HRIRT) shall:

a. Review critical aspects of a program's human-rating process beginning in formulation and continuing through the Flight Readiness Review (FRR) of the first flight (Requirement 30709). (This may include the review of verification results/content, verification compliance and closeout review, or any participation in design certification reviews/acceptance reviews.)

b. Review each program's proposed human-rating plan, including design criteria, system designs, test requirements and procedures, software design, test and verification requirements, safety and reliability requirements, human factors engineering requirements, health requirements, and other program elements required to achieve human rating (Requirement 30710).

c. Review program verification plan in relation to human-rating requirements (Requirement 30711).

d. Review all human-rating requirements tailoring and deviations to the NPR 8705.2 (Requirement 30712).

e. Transmit a recommendation to the AA for OSF or his/her designee, to accept, modify, or reject the proposed human-rating plan (Requirement 30713). If the recommendation is to reject or modify the plan for human-rating, the independent review team shall provide appropriate recommendations on changes required (Requirement 30714).

f. Provide recommendation regarding adequacy of compliance of any crewed system or system that interacts with a crewed vehicle prior to certification (Requirement 30715).

g. Provide a recommendation to the AA for OSF regarding certification of any human space flight system prior to first operational flight (Requirement 30716).
