ACCEPTABLE RISK CRITERIA


I





Introduction

Per NPR 7120.5, NASA Space Flight Program and Project Management Processes and Requirements, the payload project will implement the NASA continuous risk management process and develop a stand-alone Risk Management Plan that includes the content required by NPR 8000.4, Risk Management Procedural Requirements. The payload project shall follow KSC’s Safety and Mission Assurance Launch Services Division Risk Management System for risks impacting NASA KSC or KSC contracted facilities and shall apply AFSPCMAN 91-710 for risks impacting Air Force Ranges.



Note: See Volume 1 Chapter 3 of this document and NASA ELV Payload Safety Hazard Report NF 1825 for additional guidance.

Payload safety introduction briefing (PSIB)

I





A5.2.1. The Payload Safety Introduction Briefing (PSIB) is often the first formal meeting of the PSWG. PSIB presenters typically include the payload project, PSWG Chairperson, Range Safety, Launch Site Integration Manager (or equivalent), and other members of the PSWG as needed. The payload project is expected to provide the following information to a level of detail that is based on information availability and is consistent with the complexity of the mission, the maturity of the conceptual design, and the launch vehicle and launch site location.

C





A5.2.1.1. Overview of the System Safety Program as defined by the project's DRAFT System Safety Plan (see Volume 3, paragraph 4.1.1.).

C





A5.2.1.2. Identification of organizational roles and responsibilities.

C





A5.2.1.3. Description of payload, instruments, and anticipated ground support equipment.

C





A5.2.1.4. Description of the flight path in terms of azimuth and trajectory. Identification and description of planned return-to-earth payload recovery or sample return activities and support if applicable.

C





A5.2.1.5. Identification of potential mission-unique ground support equipment required for pad operations.

C





A5.2.1.6. Identification and a preliminary assessment of potential hazards associated with payload and payload to launch vehicle integration, multiple payloads from the same or other projects, and ground systems documented in a preliminary hazard list.

C





A5.2.1.7. Overview of the project's requirements tailoring process and planned activities for tailoring NASA-STD 8719.24 Annex, identifying any known critical concerns to be addressed during the tailoring process.

C





A5.2.1.8. Identification of non-applicable chapters and sections using the NASA-STD 8719.24 Annex Table of Contents, Volume 3 and Volume 6, as they relate to payload systems, instruments, operations and hazards known to date.

Note: A NASA-STD 8719.24 Annex Table of Contents Form is provided on ELV Payload Safety Program website at http://kscsma.ksc.nasa.gov/ELVPayloadSafety/default.html under the “Forms” button.



C





A5.2.1.9. A list of any known tailoring issues, previously approved noncompliances (i.e., waivers, ELS), and previously approved alternative approaches.

C





A5.2.1.10. Any potential hazardous failure modes, failure probability, and performance characteristics of the payload during ground operations.

C





A5.2.1.11. Identification of planned studies and analyses that support safety requirements, including scheduled completion.

C





A5.2.1.12. Description of processing flow and anticipated schedule, integrated with major project milestones.

C





A5.2.1.13. Identification of facility requirements, including launch complex, hazardous assembly and checkout areas, and ordnance and propellant storage requirements.

C





A5.2.1.14. Identification and discussion of potential contingency operations, for example, depressurization, propellant offload, and accessibility after fairing installation.

C





A5.2.1.15. Recommendations for future safety Technical Interchange Meetings, reviews, working groups, subject matter expert support, resolution of unmet requirements, Design Reviews, and other topics as deemed necessary.

C





A5.2.2. The PSWG Chairperson, in conjunction with Range Safety, presents an overview of the payload safety review process including PSWG membership activities, safety review milestones, and deliverables. Additionally, the payload project is reminded to follow NPR 8621.1 NASA Procedural Requirements for Mishap and Close Call Reporting, Investigating, and Recordkeeping for mishaps, close calls and contingencies.

Note: Mishap and close call reporting, investigating, and record keeping as well as contingency preparedness and planning fall under the NASA Program Manager for Mishap Investigations and the various programs and projects in accordance with NPR 8621.1 and are not under the purview of the ELV Payload Safety Program.

C





A5.2.3. The Launch Site Integration Manager (or equivalent), as the payload project’s liaison at the launch site, typically provides an overview covering their coordination efforts and support for the payload at the processing facility.
