The investigation into the collision with water involving a Grumman American Aviation Corp G-73, VH-CQA, 10 km WSW of Perth Airport, Western Australia on 26 January 2017 is continuing.
The final report has completed the drafting phase and is now undergoing an internal review.
Final ATSB investigation reports undergo a rigorous internal review process to ensure the report findings adequately and accurately reflect the analysis of available evidence. Final investigation reports also undergo other technical and administrative reviews to ensure the reports meet national and international standards for transport safety investigations.
Following the completion of the internal review, the report will be sent to directly involved parties for comment before the report is finalised and published.
Currently, the anticipated completion and publication date of the final report is during the first quarter of 2019.
Should any safety issues be identified during any phase of the investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.
