The reliability characteristics and parameters inherent to the design of the product and its breakdown elements are captured in this data exchange set.
Reliability and Failure Mode specification information is summarized in Figure 15 below.
The product in scope and its component assemblies and parts. Can be either a part, or an element in a logical breakdown structure of a defined end item. This is normally defined by an End Item Acronym Code.
The product in focus can have different versions of the product, each of which, has a different breakdown. Models are normally identified by a Usable on Code.
The product in focus and its product model breakdowns can be represented via a physical breakdown (e.g. follows the design drawing structure) or a functional breakdown (e.g. represents functions of the product, propulsion, fuel, communications, etc). Breakdowns may also be hybrid or zonal.
The identifier assigned to each physical or functional element in the breakdown of the product. An Logistics Support Analysis Control Number is normally used for the breakdown element.
Captures the reliability and maintainability characteristics and logistics considerations of each breakdown element based on the design. Parameters include breakdown element functions, failure rate, mean time to repair, etc.
Captures the failures modes; their effect on next higher breakdown elements and the product in focus; the criticality of failures with respect to human life and mission; and the ability to identify that a given failure mode has occurred. Information from this analysis would trigger the requirement for an unscheduled task.
For all critical failures, captures the preventive maintenance task(s) that would preclude occurrence of the failure. Information from this analysis would trigger the requirement for a scheduled task.
The action that would correct a failure or preclude a failure by performing a scheduled task. This is delineated in the Task Analysis Data Exchange Set.
