The papers presented at the second NASA-Wide Reliability and Quality Assurance Meeting are published to disseminate current experiences and information. These papers, presented at NASA Headquarters on November 29 - December 1, 1966, are one means of exchanging current NASA reliability and quality assurance knowledge between projects and programs. This publication has been marked "FOR NASA USE" since it contains management opinions and contract experiences. Publication of papers suitable for wide dissemination in the Government, industry and University community is expected to be made separately. John E. Condon, Director, Reliability & Quality Assurance.
