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 7 June 2013, the ATSB commenced an investigation into a ground proximity warning system (GPWS) event involving a Hawker Beechcraft B200C, registered VH-LTQ, near Strahan aerodrome, Tasmania on 3 June 2013.

Examination of the information collected during the investigation determined that the GPWS warnings received by the pilot were false. The operator advised the ATSB that they had identified that the aircraft’s terrain awareness and warning system (TAWS) database did not include Strahan aerodrome resulting in the false warnings and have put in place measures to prevent its reoccurrence.

Accordingly, the ATSB decided that there was limited potential to enhance transport safety by continuing this investigation, and has elected to discontinue it.
