MIL-STD-1629A3*1 Failure predictability. Enter information on knownincipient failure indicators (e.g., operational performance variations)which are peculiar to the item failure trends and permit predictingfailures in advance. When a failure is predictable in advance, describethe data that must be collected, how it will be used to predict failure,and identify any tests or inspections that may be accomplished to detectevidence of conditions which could cause the failure mode.. .3.2 Failure detection means. Identify how each failure modewill be detected by the organizational level maintenance technician andto what indenture level they will be localized. Describe the method bywhich ambiguities are resolved when more than one failure mode causesthe same failure indication. Describe any monitoring or warning devicethat will provide an indication of impending failure and any plannedtests or inspections which could detect occurrence of the failure mode.Identify to what indenture level failures can be isolated by the use ofbuilt-in-test features and indicate when ancillary test equipment willbe required for fault isolation.3.3 Basic maintenance actions. Describe the basic actionswhich, in the analyst’s judgement, must be taken by the maintenancetechnician to correct the failure. Identify the special design provisionsfor modular replacement and tileprobable adjustmcn~ and calibril&iunrequirements following repair.3.4 Remarks.
