4、d by American Institute of Aeronautics and Astronautics Approved 17 November 2008 American National Standards Institute Abstract This Standard provides the basis for developing the performance-based Failure Review Board (FRB), which is a group consisting of representatives from appropriate project o

5、rganizations with the level of responsibility and authority to assure that root causes are identified and corrective actions are effected in a timely manner for all significant failures. Although good engineering practice suggests that most product development projects should include a formal FRB, t

6、he basic FRB functions may devolve to a single individual on small projects. Planning and reporting requirements and analytic tools are provided for contractors.

ANSI/AIAA S-102.1.5-2009 7 5 Detailed Requirements The following detailed requirements pertain to the performance-based FRB process defined in Annex B. 5.1 Operating Procedures Prior to implementing the FRB process, the contractor shall document and approve FRB oper

14、ating procedures that include the following activities. a) establishing minimum qualifications for FRB members and defining the scope or extent of their authority; b) allowing the acquisition activity to appoint a representative to the FRB as an observer; c) reviewing each verified failure report fr

15、om appropriate developmental activities such as inspections and tests, including the subcontractors verified failures, each anomaly analysis option, and each corrective action option; d) authorizing appropriate anomaly investigations and analyses, as needed, to assure root causes are identified; e)

16、authorizing appropriate corrective actions; f) documenting the results of each FRB meeting, including minutes and action items, as a controlled record; and g) summarizing the status of the FRACAS (e.g., significant failures, impact of anomaly management on project budget, status of delinquent correc

17、tive actions, and number of open/closed anomalies) in a report to project management at significant milestones or as directed. 5.2 Anomaly Investigations and Analyses Anomaly investigations and analyses shall be approved and initiated, as needed, to ensure that the root cause and appropriate correct

18、ive actions are identified. The output of an anomaly investigation or analysis shall include the following information. configuration controlled documentation of the anomaly; verification of the anomaly; identification of candidate anomaly root-cause sites using an appropriate tool, such as fishbone

19、 analysis; identification of candidate singular and multiple anomaly mechanisms that can result in the observed anomaly, using an appropriate tool such as fault tree analysis; mapping of candidate anomaly mechanisms with possible root-causes, using an appropriate tool such as fault tree analysis; an

20、d identification of the sequence of events that occurred prior to the observed anomaly using an appropriate tool such as event tree analysis. NOTE This is done to identify confirmed or candidate root cause(s). The severity classification for verified failures shall be defined and qualified or rated

21、based on the down stream effect(s) on the system/mission. Table 1 provides the baseline failure severity classification criteria. ANSI/AIAA S-102.1.5-2009 8 Table 1 AIAA S-102 Failure Severity Classification Failure Severity Classification Failure Effect Description CATASTROPHIC failure would cause

22、loss of life or total disability to personnel, or failure would cause identifiably catastrophic damage to system and repairs that are beyond the capability of the user or contractor to resolve the effects. CRITICAL failure would cause severe disabling injury or severe occupational illness to personn

23、el, or failure would cause identifiably critical damage to the system and extensive repairs to resolve the effects. MARGINAL failure would cause minor injury or minor occupational illness to personnel, and those injuries or illness may require hospitalization but they are not disabling, or failure w

24、ould cause identifiably marginal damage to the system and acceptable level of repairs and downtime to resolve effects. MINOR failure would cause minor injury or minor occupational illness to personnel, but those injuries or illness would not require hospitalization, or failure would cause identifiab

25、ly minor damage to the system and minor repairs and short downtime to resolve effects. NEGLIGIBLE failure would cause less than minor injury and no occupational illness, or failure would cause negligible damage to the system and insignificant or no downtime to resolve effects, or failure is not cred

26、ible. 5.3 Corrective Actions The FRB shall ensure that appropriate corrective actions are approved, and approved corrective actions are implemented, in a timely manner.
