Section 21 (2) of the Transport Safety Investigation Act 2003 (the 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 Act requires the ATSB to publish a statement setting out the reasons for discontinuing an investigation.

On 29 July 2017, the ATSB commenced an investigation into a collision with terrain involving a Zaklad Remontow I Produkeji Spreztu Lotnicz MDM-1P FOX-P glider, registered VH-GPT, at Lismore Airport, New South Wales.

The ATSB found that while conducting an aerobatic display, the glider impacted the ground heavily during the final manoeuvre. The pilot was seriously injured. Examination of the aircraft identified no mechanical issues or faults that may have contributed to the accident.

The Gliding Federation of Australia has conducted an investigation of this accident and the public report (S-1010) is availiable on their website.

The ATSB has also reviewed the safety and administrative procedures necessary to conduct air shows and found that, in this case, preparations were consistent with regulatory requirements. The ATSB investigation AO-2017-013, Mallard aircraft, Perth, January 2017 is examining a range of issues associated with air shows, including the suitability of the regulations, approval and oversight of air shows, and compliance with regulatory approvals during air shows.

In this case, the ATSB did not identify any organisational or systemic issues that contributed to the development of the accident or that might adversely affect the future safety of aviation operations. The ATSB assessed that no safety issues would be identified through further investigation. On that basis, the ATSB will discontinue this investigation.
