A helicopter pilot involved in one of Australia’s worst aircraft disasters had a mental ‘breakdown’ and used cocaine the day before taking tourists on joy flights, a coroner has heard.

Ashley Jenkinson, 40, was among four people who died when his Sea World chopper collided mid-air with another outside the Gold Coast theme park on January 2, 2023.

Mr Jenkinson’s fiancée, Kosha Richardson-Johnson, told an inquest the pilot had a breakdown in 2022 and used cocaine at social events ‘probably six to eight times’ a year.

She said he took a small bag of cocaine to a 2022 New Year’s Eve party and saw him use the drug at 3am on January 1, a day before the horror crash.

The pilot took the drug on days before taking tourists on joy flights for Sea World ‘two or three times a year’, Ms Richardson-Johnson said via videolink.

Mr Jenkinson tested positive for cocaine during an autopsy, Coroner Carol Lee has heard, but an Australian Transport Safety Bureau investigation found he was ‘unlikely to have been directly affected by the drug at the time of the accident’.

Asked by counsel assisting Ryan Nattrass about Mr Jenkinson’s ‘breakdown’ before Christmas 2022, Ms Richardson-Johnson said it came after conversations about him feeling stressed at work.

‘I found him in the wardrobe crying. I said, “What’s wrong?”,’ she said. ‘That’s when he had a breakdown. He said, “You don’t know what kind of pressure I’m under”.’

The crash not too far above the ground on the Gold Coast but the height was enough to cause catastrophic damage

Mr Jenkinson had been working long hours to keep up with paperwork as Sea World’s chief pilot and get new helicopters ready for the busy holiday period, Ms Lee heard.

Ms Richardson-Johnson said she was concerned for Mr Jenkinson’s health but decided against asking his boss for a day off.

There was never concern Mr Jenkinson might have a cocaine addiction, she said.

Two people testified on Tuesday they saw Mr Jenkinson inhale what they assumed was cocaine at the New Year’s Eve party.

No other Sea World Helicopters staff or pilots attended the party, Ms Lee heard.

Industrial oil salesman Stephen Gill said he entered a shed at the party about 8pm and saw a ‘white powder substance’ on a toolbox.

He previously saw Mr Jenkinson do ‘probably three or four lines throughout the night’ on occasions when he took cocaine, Mr Gill said.

Digital marketing company director Ross Meadows – one of Mr Jenkinson’s ‘best mates’ – said he saw the pilot inhaling a white substance in the shed about 9pm.

British couple Diane and Ron Hughes were sadly killed in the disaster

Mr Meadows did not think to report his friend to aviation authorities and did not speak to him about cocaine use.

‘He was his own person. I’m not responsible,’ he told the inquest.

Mr Jenkinson was killed along with British newlyweds Ronald and Diane Hughes – aged 65 and 67 – and Sydney mother Vanessa Tadros, 36, in the 2023 tragedy.

Under cross-examination from Tadros family barrister Gerard Mullins KC, Mr Meadows said he knew cocaine and flying did not mix.

‘An important part of a helicopter organisation targeting tourists is to promote themselves as a safe operator? Did it not occur to you to let them know of this illegal cocaine use?’ Mr Mullins said.

‘No,’ Mr Meadows said.

Vanessa Tadros’ son Nicholas – who was aged just 10 when he lost his leg in the crash – attended the inquest on Tuesday with his father Simon.

Mr Meadows’ company had provided social media marketing for Sea World Helicopters, Ms Lee heard.

Sea World owner Village Roadshow Theme Parks sold its joy flights operation to Sea World Helicopters in 2019.

The inquest will hear from Sea World Helicopters executives next week.
