RA-006-013-1A, OFFICE OF MANNED SPACE FLIGHT - APOLLO PROGRAM: PROCEDURE FOR FAILURE MODE, EFFECTS, AND CRITICALITY ANALYSIS (FMECA) (AUG-1966)., This document provides guidelines for the accomplishment of Failure Mode, Effects, and Criticality Analysis (FMECA) on the Apollo program. It is a procedure for analysis of hardware items to determine those items contributing most to system unreliability and crew safety problems. This document is applicable to all NASA activities with cognizance over design, development, and test of Apollo flight, ground, and related equipment which have major impact on mission success. It may be invoked in equipment contracts in whole or in part,where design or development is involved, as a portion of the reliability engineering and as the guideline for carrying out the activity, predicated on budget considerations, equipment criticality, schedules, and other factors. The ground rules for the use of FMECA may call for substitute overstress tests on structural parts or for other design/development tests of the system in place of the FMECA, or these rules may not require an FMECA on those parts of the system that are established by preliminary FMECA to be noncritical to system operational success.
