In-flight breakup involving Robinson R44 Raven
Based on closed-circuit television (CCTV) footage and an examination of the wreckage, the ATSB investigation into the fatal R44 helicopter accident near Broome Airport on 4 July 2020 has determined that the helicopter experienced an in-flight breakup. The tail rotor gearbox assembly, tail rotor and empennage assembly separated soon after the helicopter lifted off. The fuselage then fell to the ground out of control.
A preliminary report will be released within about 30 days of the accident. A final report will be published at the conclusion of the investigation.
Should any safety critical information be discovered at any time during the investigation, the ATSB will immediately notify operators and regulators so appropriate and timely safety action can be taken.
