Radiothelephony Readback Compliance and its Relationship to Surface Movement Control Frequency Congestion

The Australian Transport Safety Bureau (ATSB) is an operationally independent
multi-modal Bureau within the Australian Government Department of Transport
and Regional Services. ATSB investigations are independent of regulatory, operator
or other external bodies.

The ATSB is responsible for investigating accidents and other transport safety
matters involving civil aviation, marine and rail operations in Australia that fall
within Commonwealth jurisdiction, as well as participating in overseas
investigations involving Australian registered aircraft and ships. A primary concern
is the safety of commercial transport, with particular regard to fare-paying
passenger operations.

The ATSB performs its functions in accordance with the provisions of the
Transport Safety Investigation Act 2003 and Regulations and, where applicable,
relevant international agreements.

The object of a safety investigation is to enhance safety. To reduce safety-related
risk, ATSB investigations determine and communicate the safety factors related to
the transport safety matter being investigated.

It is not the object of an investigation to determine blame or liability. However, an
investigation report must include factual material of sufficient weight to support the
analysis and findings. At all times the ATSB endeavours to balance the use of
material that could imply adverse comment with the need to properly explain what
happened, and why, in a fair and unbiased manner.

Central to the ATSB’s investigation of transport safety matters is the early
identification of safety issues in the transport environment. The ATSB prefers to
encourage the relevant organisation(s) to proactively initiate safety action rather
than release formal recommendations. However, depending on the level of risk
associated with a safety issue and the extent of corrective action undertaken by the
relevant organisation, a recommendation may be issued either during or at the end
of an investigation.

The ATSB has decided that when safety recommendations are issued, they will
focus on clearly describing the safety issue of concern, rather than providing
instructions or opinions on the method of corrective action. As with equivalent
overseas organisations, the ATSB has no power to implement its recommendations.
It is a matter for the body to which an ATSB recommendation is directed (for
example the relevant regulator in consultation with industry) to assess the costs and
benefits of any particular means of addressing a safety issue.
