According to the report, the “serials on 29 November 2006 were planned to be conducted to a static target to overcome the perceived lack of recency in such approaches. Accordingly, at 1403 KANIMBLA’s engines were declutched and at 1412 her shaft brakes were engaged. The evidence of LCDR Collins indicated that KANIMBLA had drifted 600 yards in a westerly direction from the time BLACK 1 launched to the time of the accident at 1611.”
One of the reports findings is that: “It does not appear to have been appreciated by 171 Avn Sqn how KANIMBLA would lie in the water relative to the wind while drifting. Not knowing this compromised 171 Avn Sqn’s ability to best brief how the wind on 29 November 2006 would most likely be coming around the ship as the target.”
