The powerline maintenance provider advised that, immediately following the accident, it:
Suspended all operations of the helicopter operator until it was satisfied that all appropriate safety procedures were in place.
Commissioned an independent audit to report on certain aspects of [the helicopter operator’s] operations including safety management systems and training procedures.
In addition, the powerline maintenance provider advised of the following amendments to its operational procedures:
Prior to the incident a debrief was held with [the helicopter operator’s] crew prior to the commencement of each planned maintenance job. We now require that [the helicopter operator] is to provide a formal documented debrief to [us] and the [asset owner] after each planned maintenance job. The exceptions to this directive are that and incident occurring during flight must be reported immediately and that because of work load the maximum time within which to hold a debrief is one week.
As advised earlier [we] have retained an external auditor to report on the safety and operational practices of [the helicopter operator]. Audit recommendations have been adopted.
The ATSB is satisfied that the action taken by the powerline maintenance provider adequately addresses the safety issue.
