The initial report from atsb says:
The investigation is continuing and will include:
1. An ongoing examination of operational issues including pilot training and checking
2. Continued analysis of recorded radar data and voice transmissions
3. An ongoing human factors review.
It is anticipated that the final investigation report will be released to the public in the first quarter of calendar year 2012.
Item 3 did not occur with the Norfolk Island "investigation" by atsb, it will be interesting to see if it has happened with PGW.
and if not, WHY NOT
