2、y and maintainability (R Environmental and OperationalProvided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-At KSC, LSOC R&M Engineering has developed a checklist to cover reliability, maintainability, safety and quality assurance issues for Space Shuttle

3、GSE development. This checklist is used during the design phase of the GSE projects. R&M concerns and requirements for the Shuttle program are addressed in the checklist and brought to the attention of design and project engineering.Technical Rationale:The checklists have resulted from operational e

4、xperience with the Shuttle Program. The document which incorporates the checklist also includes a cross reference which relates items on the Reliability and Maintainability Checklists to Shuttle Program requirements. The table of contents of the document has been included with this practice. A sampl

5、e is also included of some of the items from the Reliability, Quality, Maintainability and Safety Checklists. There are in excess of 60 pages of checklist items which actually comprise the Checklists for Reliability, Quality, Maintainability, and Safety.The format and the topics addressed in the che

6、cklist will also work for other applications and the checklist is designed to be tailored to meet the specific needs of the individual programs. The complete checklist is contained in reference 2.PROCEDURE FOR PERFORMING SPC DESIGN REVIEWS, S&R-P-003 TABLE OF CONTENTS (Reference Only) INTRODUCTION1.

13、s, S&R-P-003.Impact of Non-Practice: Failure to use a checklist during the design phase could result in an R&M issue or consideration being overlooked. This could have an impact on the final reliability. Also, making reliability improvements later than the design phase, such as in the prototype or p

14、roduction phase, would result in a much greater increase in cost for the improvement than if the change were done earlier.Related Practices: N/AAdditional Info: Approval Info: a71 Approval Date: 2000-03-01a71 Approval Name: Eric Raynora71 Approval Organization: QSa71 Approval Phone Number: 202-358-4738Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-
