This accident has been over speculated. We need the ATSB to do its job and publish the report.
In Feb the ATSB put out a media release essentially saying that the report was done but release was delayed because of a requirement to give interested parties time to comment with the inference that this involving international parties was increasing this period to 60 days. This 60 day period has now elapsed by 30 days and still no report.
The exact same update was issued on the same day for the 3 September 2015 incident at Mt Hotham with VH-OWN & VH-LQR- an incident that occurred 32 months ago. .
The list of pending reports has grown to 109.
This is from the ATSB's current strategic plan:
" The Government’s recent Budget measures, and the ATSB’s organisational change program, position the ATSB to reduce its investigation backlog and increase its capacity to complete complex investigations within 12 months, which is a key deliverable of the ATSB."
The ATSB is clearly failing to do its job by any measure.
