The ATSB is investigating an airframe overspeed involving a Diamond Aircraft Industries DA40, VH-EQF, about 63 km east of Kingaroy Airport, Queensland, on 12 February 2025.
During a manoeuvre demonstration as part of a training flight, the instructor lost control of the aircraft and an airframe overspeed occurred. The investigation is continuing.
The draft report internal review process has been completed. The draft report has been distributed to directly involved parties (DIPs) to check factual accuracy and ensure natural justice. Any submissions from those parties will be reviewed and, where considered appropriate, the draft report will be amended accordingly.
Following the external review process, any submissions and amendments to the draft report are internally reviewed. Once approved, the final report is prepared for publication and dissemination and released to DIPs prior to its public release.
The final report will be released at the conclusion of the investigation. Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties, so that appropriate safety action can be taken.
