The inconsistent application of the operator’s safety management system to the identification and rectification of database anomalies, and intermittent notification of these anomalies to crews increased the risk of inadvertent flight crew non compliance with published instrument approach procedures.
A procedure has been developed to properly manage the risks identified in this safety issue.
In response to these safety issues, the operator has enhanced its safety management system in respect of its data management.
These auditable enhancements include the:
• Introduction of a controlled system and designated manager to ensure the consistent notification by flight crew of identified data anomalies.
• Requirement for the immediate management of reported data anomalies and their notification to all flight crew.
• Establishment of an anomaly rectification process that records actions and notifies the data supplier.
• Requirement to validate any updated database notifications prior to their use.
• Acquittal of rectified data anomalies and their notification to flight crew.
The ATSB is satisfied that the action taken by Tiger Airways will adequately address these safety issues.
