Australia to standardize air operations

As a result of recent accidents involving aircraft working on wildfires, authorities in Australia are developing standardized procedures across the country in order to reduce the chances of additional mid-air collisions and other accidents involving firefighting aircraft.

Here is an excerpt from an article at Flightglobal:

Australia’s fire authorities are reviewing a draft firefighting operations manual designed to standardise aerial firefighting procedures across the country.

The development of the manual follows a firefighting review conducted in 2009 by the Civil Aviation Safety Authority after a number of accidents involving firefighting aircraft in the 2009 fire season.

The issue of a lack of standardised procedures was highlighted in the investigation by the Australian Transport Safety Bureau of a midair collision between a Eurocopter AS350B and a Eurocopter/Kawasaki BK117 performing aerial firebombing operations 20km (11nm) south-east of Orange aerodrome, New South Wales in December 2009.

The final report into the accident was released in late November. During one of the water drop sequences, while in the vicinity of the drop point, the BK117’s main rotor blade tip contacted the trailing edge of the AS350B’s vertical fin above the tail rotor arc, resulting in slight damage to the latter.

Although there were no injuries, “the outcome could have been more serious”, the ATSB points out. One of the accidents involving firefighting aircraft in New South Wales during the 2009 fire season resulted in the loss of a life.

In its investigation of the BK117 and AS350B collision, the ATSB found that there were no published procedures for pilots to follow to ensure separation from other aircraft when there was no air attack supervisor present.

Rather, the system relied on the airmanship and experience of pilots to mutually arrange separation. The ATSB determined that neither pilot in that incident was aware of the position of the other helicopter as they approached the drop point.
