DATA ITEM DESCRIPTION

Title: FAILURE SUMMARY & ANALYSIS REPORT

Number: DI-SESS-80255A Approval Date: 20141219 AMSC Number: 9506 Limitation: No DTIC Applicable: Yes GIDEP Applicable: Yes http://www.dtic.mil/dtic/submit http://www.gidep.org/data/submit.htm Preparing Activity: AS Applicable Forms: N/A

Use/relationship:

This report presents a summary of the individual failures that occur prior to and during the reporting period and describes the analysis and corrective actions performed. This report is used to evaluate the contractor’s failure reporting, analysis, and corrective action efforts in accordance with the solicitation. This Data Item Description (DID) contains the format, intended use information, and content preparation instructions for the data product generated by the specific and discrete task described in the solicitation, and should be tailored appropriately.

This DID supersedes DI-RELI-80255.

Requirements:

1. Format. The Failure Summary and Analysis Report shall be in contractor’s format.

2. Content. The report shall summarize the results of the contractor’s Failure Reporting, Analysis, and Corrective Action System (FRACAS) implementation required by the statement of work, and shall include a cumulative tabulation of failure data. Failures which occurred during the latest report period shall be identified by suitable notation. The report shall include the following elements at a minimum:

1. Failure number

2. Failure analysis number

3. Failure date

4. Name of engineer responsible for failure analysis

5. Failed part name

6. Failed part number (e.g. national stock number (NSN), logistics control number, work unit code)

7. Manufacturer of failed part

8. Subassembly name and number

9. Major assembly name and number

10. Equipment name and serial number

11. Failed part’s accumulated test or field operational life data

12. Test or mission being performed when the failure occurred

13. Test or mission mode of operation and environmental and use conditions when the failure occurred

DI-SESS-80255A

14. Failure symptoms and description of detection or diagnosis methods (e.g. Built In Test)

15. Failure effects (e.g. none, degradation, abort)

16. Repair action (e.g. remove/replace)

17. Failure mode description

18. Description of engineering analysis method employed in failure analysis

19. Failure mechanism/cause of failure

20. Contributing factors, including multiple factor interactions, or secondary effects of the failure

21. Categorization of failure (e.g. equipment design, equipment manufacturing workmanship, part design, part manufacturing workmanship software errors, unverified, intermittent, non-relevant)

22. Information on previous corrective actions for the same part and/or failure mode

23. Corrective action required to mitigate the failure mode, including:

i. Identification of the failure mode

ii. The recommended process or process control changes, when the failure cause is due to workmanship defects

iii. Proposals for retrofit of all equipment already delivered or assembled, including recommended effectivity, in accordance with the contract

iv. Disposition of all defective material and material rendered obsolete because of any necessary redesign, to assure their exclusion from production items

v. Identification of previous functional and environmental qualification tests, if any, invalidated by the corrective action changes and recommendation of those tests that should be repeated, in accordance with the terms of the contract, to demonstrate the corrective action’s effectiveness

vi. Effect on operational and diagnostic software programs and plan for changes, if necessary

24. Corrective action status

25. The recommended fix effectiveness factor (FEF) to be applied to the failure mode based on the proposed corrective action

26. Rationale for any open failure analyses past the contract-specified closeout time

27. Severity criticality ranking of the failure modes. The severity classification categories are:

i. Category I - Catastrophic - A failure which may cause death or system loss (i.e., aircraft, tank, missile, ship)

ii. Category II - Critical - A failure which may cause severe injury, major property damage, or major system damage resulting in mission loss.

iii. Category III - Marginal - A failure which may cause minor injury, minor property damage, or minor system damage which will result in delay or loss of availability or mission degradation.

iv. Category IV - Minor - A failure not serious enough to cause injury, property, or system damage, but which results in unscheduled maintenance or repair.
