Reliability Analysis-An overview

The reliability analysts/engineers carry out periodical analysis of fleets of aircraft to ascertain their utilization and performance as part of their operations. The conclusion of this analysis is the generation of reliability reports, which is submitted to regulatory authorities as per statutory obligations.

The Reliability Analysis process in the Reliability Management process chain provides analytical and reporting tools to generate a diverse range of reliability reports. A set of configured reports for an aircraft fleet can be generated at the click of a button. These reports provide crucial and wide ranging information on areas of aircraft and component reliability. Information including unscheduled and scheduled removals of parts, MIREP and PIREP discrepancies, fleet/aircraft utilization and operational interruptions of aircraft are highlighted in these reports. Analytical tools provide the ability to query and find the operational/maintenance history of parts associated with a reliability fleet as well as discrepancy details of aircraft.

The premise of reliability reports are reliability fleets, fleets of aircraft created exclusively for reliability analysis and reports. To facilitate analysis across reliability fleets, groups of fleets called as reliability report groups can also be created. This allows for the generation of reliability reports for all the reliability fleets associated with the group with a single mouse click.

The activities offered by the can be classified into Setup, Report Generation and Analytical tools.

• Setup activities enable users to maintain reliability fleets, quick codes and report generation parameters.

• Report Generation activities help users to upload operational data from other business processes as a prelude to reliability reporting. Further, discrepancy data can be cleansed prior to report generation for improving their statutory relevance. As a culmination of reliability analysis, the entire list of configured reports is generated for a reliability fleet or for all reliability fleets in a reliability report group.

• Analytical tools/activities render online enquiries/reports  and help users to evaluate crucial information

Getting familiar with the activities

Key facts about the Reliability Analysis process,

• The information pertinent to the preceding months in a report is retrieved from the already published reports for those months and hence may not reflect the information available at the current point of time.

• The discrepancy details cleansed/refined for report generation is not updated in the transactional databases

However, information is generated for reliability reports on the following assumptions,

• The transactional or operational data (from Line Maintenance, Configuration, Discrepancy Management and , Component Maintenance) necessary for reports is available for the specified month of the report.

• The reliability reports for the months preceding the month of the report must be published already. This implies reports for every month since the Reliability Analysis component became operational, must have been published.
