In 2011–12, CASA was responsible for a single portfolio outcome:
Maximise aviation safety through a regulatory regime, detailed technical material on safety standards, comprehensive aviation industry oversight, risk analysis, industry consultation, education and training.
The outcome was set out in the 2011–12 Portfolio Budget Statements for the Infrastructure and Transport portfolio.
CASA’s results against its two portfolio-level performance indicators are shown in Table 2.
|Key performance indicator||Target||Result|
|Number of accidents per hours flown, by industry sector||Reducing trend||
General aviation operations continue to have an accident rate higher than for commercial air transport operations: in 2011, about four times higher for accidents, and nine times higher for fatal accidents.a
Charter operations accounted for most of the accidents, including two fatal accidents in 2011.a
In most operation types, helicopters had a higher rate of accidents and fatal accidents than aeroplanes, except for in charter operations. Even though the fatal accident rate is generally higher, helicopter accidents are on the whole associated with fewer fatalities than fixed wing aircraft.a
|Number of incidents per hours flown, by industry sector||Reducing trend||There has been an increase in the number of incidents involving commercial air transport aircraft reported to the ATSB over the past 10 years.b|
ATSB = Australian Transport Safety Bureau
A: ATSB, Aviation Occurrence Statistics 2002 to 2011, 30 May 2012, p. iii.
B: ATSB, Aviation Occurrence Statistics 2002 to 2011, 30 May 2012, p. 13. The increase in number of incidents reported may be attributed to the introduction of the Transport Safety Investigation Regulations 2003, which provide a prescriptive list of the types of occurrences that are required to be reported to the ATSB. This increase may also reflect a better reporting culture. More incidents were reported in 2011 than in any other year since 2002.
