Aviation Occurrence Statistics - 1 January 1999 to 31 Mar 2009

The data contained in this document is dynamic and subject to change
based on additional information received post publication.

Where 2009 data has been referred to in this report, this includes data up
to 31 March 2009.

A new table (Table 2) has been added displaying number of occurrences
by the primary occurrence type.

Data includes all occurrences including non-VH registered recreational
aircraft and parachute accidents not specifically relating to aircraft safety.

The significant increase in incident numbers from 2003 are the result of a
healthier industry wide reporting regime supported largely with the
introduction of the T81 in 2003 which provided specific guidelines for
mandatory reporting requirements.

The increase in the number of Serious Incidents for 2008 is a direct result
of a review of the classification of Immediately Reportable Matters (TSI
Reg 2.3) where aviation safety was compromised. This took effect in
July 2008.

The current TSI Regulation 2.4(2) ‘Aircraft operations other than air
transport operations’ does not require the mandatory reporting of
‘Airspace Incursions’. In July 2005 the ATSB recommenced the
recording of a_ll Airspace Incursions as a ‘Routine Reportable Matter’.
Given the anomaly with records from 2003 to 2005, a decision was made
to update the SIIMS database with the previously omitted data. These
numbers have now been added to Table l to reflect the change.

Primary occurrence - An occurrence can have several ‘occurrence types”
associated to it. The ‘primary’ occurrence type is the one deemed to be of
most importance to the occurrence.

‘Airspace Incursions’ between 2003 to 2005 for ‘Aircraft operations
other than air transport operations’ (see notes for Table l) have been
included in Table 2.

Data includes all occurrences including non-VH registered recreational
aircraft and parachute accidents not specifically relating to aircraft safety.
