Section 21 (2) of the Transport Safety Investigation Act 2003 (TSI Act) empowers the Australian Transport Safety Bureau (ATSB) to discontinue an investigation into a transport safety matter at any time. Section 21 (3) of the TSI Act requires the ATSB to publish a statement setting out the reasons for discontinuing an investigation.

On 15 October 2014, the ATSB commenced an investigation into a reported vertical speed exceedance involving an Embraer ERJ 190, VH-ZPN, near Hobart Airport, Tasmania on 1 October 2014.

Examination of the information collected during the investigation indicated that the aircraft did not exceed the allowable vertical speed and that the event did not constitute a Transport Safety Matter under the Transport Safety Investigation Act 2003.

On that basis, the ATSB has decided to discontinue the investigation.
