MIL-STD-1798C
5.5.3.5 Risk Assessments.
Risk decisions (acceptance of risk) for MECSIP equipment shall be made at a level of responsibility that corresponds to the degree of risk per MIL-STD-882. The Single Manager (SM) will provide a response to each SIB recommendation affecting MECSIP equipment, obtaining concurrence through the appropriate management level per MIL-STD-882 for that response.
5.5.3.6 Perform analysis.
It is essential to establish the extent to which the analysis shows there is potential to improve performance and to track the component to determine how well it improved relative to the total cost of the analysis before any analysis is actually begun. The analysis performed will be Preview, in-depth, or ACI. The Cost of Unreliability Model developed in 5.5.1.12 can be very helpful in this task.
5.5.3.6.1 Perform preview analysis.
The Program Office shall establish a process to perform a preview analysis. A Preview analysis is simply a paper review of the data available. The main goal of the Preview is to validate the data and determine if a" real" problem exists. If the paper trail was in error, the analysis can be closed. If a more thorough analysis is required to identify the problem, an in-depth analysis should be performed. A Preview analysis will be performed on functional and potential failures. Functional failures occur when there is an actual failure during operation of the component.
Most functional failures will require an in-depth analysis. Most potential failures will not require an in-depth analysis but will require extensive coordination and Service Level Agreements
(SLAs) with other agencies to resolve.
5.5.3.6.2 Perform in-depth analysis.
The Program Office shall establish a process to perform an in-depth analysis. If the Preview analysis indicates problems exist, then an in-depth analysis shall be performed. The RAT, Depot Overhaul Facility, or Contractor will perform most in-depth analyses. Before a group is selected to perform the analysis, the person requesting the analysis shall:
a. establish the objectives of the analysis (quantified wherever possible), and agree when and how the achievement is to be measured;
b. estimate how much time will be required to perform the analysis and what skills and facilities will be needed; and
c. establish the funding, site, and personnel to perform the analysis; and decide when, where, and by whom the recommendation will be implemented.
5.5.3.6.3 Analytical Condition Inspections (ACIs).
The Program Office shall establish ACIs to monitor the condition of MECSIP equipment. The ACI Program shall be conducted throughout the life of the aircraft. Corrosion, fatigue, wear out, deterioration of polymers and other damage scenarios shall be considered in the selection of inspection locations and schedules for aircraft mechanical equipment. The ACI Program shall be conducted with special emphasis on determination of when and where corrosion occurs and to evaluate the effectiveness of prototype NDI and repair actions. The MECSIP Manager shall select safety- and mission-critical subsystems upon which ACIs must be performed. The ACI will be in four parts:
a. Identify components to be inspected. Identify all items in the subsystem to be inspected.
This process will include a review of all the critical items which comprise the subsystem
