Date issued: 15 November 2002
Safety action status:

See ATSB report BS/20010005,

"Investigation into Ansett Australia maintenance safety deficiencies and the control of continuing airworthiness of Class A aircraft".

Output text

The Australian Transport Safety Bureau recommends that the Civil Aviation Safety Authority, as a part of its oversight role, review the policies and procedures for carrying out, and responding to the findings of, risk assessments of organisations that operate Class A aircraft. The review should address the adequacy of methods for:
* gathering and assessing information relevant to possible risks to safe operations
* determining, carrying out, and reviewing the CASA response to the assessed level of risk.

Initial response
Date issued: 31 October 2006
Response from: Civil Aviation Safety Authority
Action status: Closed - Accepted
Response text:

In October 2006, CASA issued Notice of Proposed Rule Making NPRM 0604MS, A Proposal to Modernise and Harmonise Rules for the Maintenance of Australian Aircraft and Licensing of Aircraft Maintenance Personnel for industry comment by 27 November 2006.

The NPRM addresses the policy outcomes of adopting a regulatory style similar to that proven by the European Aviation Safety Agency (EASA) and would amend Parts 42, 66, 145 and 147 of the Civil Aviation Safety Regulations 1998 (CASRs).

ATSB response:

The NPRM, as proposed, should address the issue in the recommendation.

Response from: Civil Aviation Safety Authority
Response status: Monitor
Response text:

The Authority acknowledges the intent of this Recommendation. The Authority's audit surveillance of operators currently comprises regular, scheduled audits that are supported by targeted risk-based audits. A Safety Trend Indicator (STI) was introduced in 1999-2000. It allows the Authority to determine, in a consistent manner, the higher likelihood of safety problems occurring with an aviation organisation. This is one factor that allows the Authority to decide which operators should be subject to extra, or risk-based, surveillance. A STI is conducted every six months and after a surveillance audit and, in developing the STI, the Authority took into account international practice.

STI is a valuable tool for providing safety trend information on particular risk issues affecting particular sectors of the industry at particular locations.

The Australian National Audit Office, in its report, Aviation Safety Compliance Follow-up Audit - Civil Aviation Safety Authority (2002), commented favourably on the approach.

The Authority is currently developing an enhanced version of STI which will capture more data and enhance the Authority's comparative risk analysis capability. The intention is to monitor each component of an airline's operations so that it can focus its audits on the component(s) of an airline that pose the greatest safety risk.

ATSB comment:

The ATSB will continue to monitor the implementation of CASA's proposed safety action.
