- A helicopter crashed on July 4 killing pilot Troy Thomas, 40, and Amber Jess, 12
- Investigators say the tail assembly of the Robinson R44 helicopter came apart
- Another pilot reported vibrations coming from the tail two days before the crash
A helicopter crash that killed a popular pilot and a 12-year-old girl was the result of the tail falling apart during flight, investigators say.
The Robinson R44 helicopter crashed on July 4 near Broome in Western Australia, resulting in the death of pilot Troy Thomas, 40, and Amber Jess, 12.
The pilot's daughter and Amber's friend Mia Thomas, 12, as well as family friend Maddison Down, 24, were also seriously injured and remain in hospital.
Australian Transport Safety Bureau chief commissioner Greg Hood said on Friday that CCTV footage and the wreckage had been examined so far in the ongoing investigation.

'ATSB investigators have been able to determine that the helicopter's tail rotor gearbox, tail rotor and tail assembly separated from the helicopter soon after take-off,' he said.
The out-of-control helicopter then fell to the ground, but CCTV footage will not be released due to its potentially distressing nature, he added.
Parts of the wreckage will be transported back to the ATSB's technical facilities in Canberra for further examination.

Mr Hood also revealed another pilot, who flew the aircraft two days earlier, had reported feeling unusual vibrations through the tail rotor pedals. Investigators have interviewed him.
Mr Thomas confirmed the unusual vibrations during a short flight and maintenance personnel subsequently conducted a dynamic tail rotor balance the day before the accident.
'At this stage, the reasons for the in-flight break-up and the significance of the reported vibrations through the tail rotor pedals are not known,' Mr Hood said.
'While the investigation is ongoing, the ATSB urges any R44 pilot that experiences unusual vibrations through the tail rotor pedals to land as soon as possible.'

In a moving family statement provided to Daily Mail Australia, relatives described Amber as an 'all-rounder' who excelled in academics, sports and community service.

'She (Amber) really was an all-rounder. She loved sport but always got academic mentions and awards at school,' the family said.
'She was also a little adventurer and loved nature and animals... and a little prankster always making people laugh. She wasn't the kind of kid that was in front of a screen.'
Having grown up in Mandurah, Amber called the beach her 'happy place' and loved spending time by the ocean.
