Technical Assistance to RAAus - Collision with terrain involving BRM Aero Bristell, 24-8555, Kanangra-Boyd National Park, New South Wales, on 16 December 2019

On 16 December 2019, a BRM Aero Bristell aircraft, recreational registration 24-8555, collided with terrain in Kanangra-Boyd National Park, near Oberon, New South Wales. The pilot was fatally injured.

In response, Recreational Aviation Australia (RAAus) commenced an investigation into the occurrence and requested technical assistance from the ATSB in the recovery of flight data from two instrumentation units – a Dynon SV-D1000 and Garmin aera 795; both of which were subsequently provided by NSW Police.

The ATSB successfully downloaded data from both devices, including flight path information and aircraft operational parameters. Figures 1 and 2 summarise this information.

Both instrumentation units were returned to NSW Police on 23 June 2020 and a technical report and all recovered data provided to RAAus on 24 June 2020.

With the completion of this work, the ATSB has concluded its involvement in the investigation of this accident. Any further enquiries in relation to the investigation should be directed to Recreational Aviation Australia.

The information contained in this update is released in accordance with section 25 of the Transport Safety Investigation Act 2003.
