To totally understand the reason for the merger of DFS and DAFS, but I do not agree. DFS-ADF is responsible to the ADF for flight safety and accident/incident investigation across the ADF. DAFS is responsible for Air Force Safety for one service only. Incorporating the two under one Group Captain with at time conflicting requirements is difficult.
DFS-ADF gained significant resources after the ADF flight safety system was found lacking post Black Hawk accident 1996. In my opinion, the merger has created an organization that cannot meet its mission.
The US military system has it merits. At service level, ground safety and aviation safety are two separate units that report to a one star general. Each unit is commanded by a GPCAPT(E), with separate resources.
Anyway, this is thread creep.
