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 evidence collection phase of the investigation will involve interviewing the involved parties, examination of maintenance records, retrieving and reviewing any recorded data and the collection of other relevant information.
A 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.
