Discontinued Investigation
Statement of Reasons
Occurrence investigations commenced from 1 July 2003 are
initially categorised as category 4 unless agreed by the ATSB
Executive to be above this level at the outset. As detailed in
Section 21 (2) of the TSI Act 2003, the Executive Director in
empowered to discontinue an investigation at any time. Section 21
(3) of the TSI Act 2003 requires the Executive Director to publish
a statement setting out the reasons for discontinuing an
investigation (commenced from 1 July 2003) within 28 days of
discontinuing the investigation.
Preliminary investigation was undertaken into a level 4
occurrence involving a SAAB 340 aircraft that had been cleared for
takeoff and an aircraft tug that entered the runway strip at Sydney
Airport on 27 August 2006. Safety action relevant to this
occurrence has been taken in response to an earlier incident of a
similar nature. Details of that safety action are contained in ATSB
safety investigation report 200505170, published on 6 December 2006
and available on the ATSB website. Given the safety action already
taken, there was limited safety benefit in continuing the 27 August
2006 investigation compared with other priorities.
Status: Downgraded the occurrence to level 5
and investigation discontinued.
