Helicopter pilot 'feeling good' despite crash after helping save house from blaze

The crashed helicopter flown by pilot Neal Andrews.

The firefighting pilot who escaped a helicopter crash unscathed says he's happy nobody was hurt and doesn't think mechanical failure or pilot error caused the crash.

Neal Andrews said he was grateful to be safe and to have helped the big firefighting effort in Marlborough this week.

A huge blaze tore across around 400ha yesterday but 60 firefighters and an "aerial assault" from helicopters and planes combined with light rain to suck the life out of the fire.

Mr Andrews, a pilot with Precision Helicopters in Blenheim, crashed in shallow water about 11am yesterday.

"I've been in the industry a long time. And things can go wrong and obviously it did go wrong yesterday."

Mr Andrews said he was counting his blessings and happy he helped save a house from the fire.

"My pride's hurt. My helicopter's written off ... the matter is we were working and we saved a house there and that was a bloody good feeling."

He also said he was grateful for support from his friends, clients and members of the community since the crash.

He said he wasn't able to reveal the cause of the crash just yet as a formal investigation was under way.

Mr Andrews said he was counting his blessings and happy he helped save a house from the fire.

"There wasn't a mechanical failure on the helicopter the way I see it. I pretty well know there wasn't ... and honestly it wasn't pilot error either."

It was earlier reported the helicopter encountered difficulty lifting water from a river with fast currents.

Mr Andrews said he was glad the firefighters won the upper hand, with a little help from the weather.

He said the fire was "rampant" yesterday but high winds fuelling it had died down.

"The fire is pretty well controlled. We've still got one of our machines on, just doing support for the ground crew," he said.

The pilot earned praise from the local fire chief.

"Neal was working for the community when this happened.

"My heart goes out to him and we'll catch up later in the day," said Richard McNamara, Marlborough Kaikoura Rural Fire Authority general manager.

Mr Andrews had helped the community many times before, he said.

"When we call him, he comes."

Mr McNamara said the cost of hiring a helicopter for firefighting usually cost roughly $1,500 to $3,500 an hour.

Precision Helicopters chief pilot Matt Newton said Mr Andrews was about 3m above the river when he encountered trouble.

"He just was loading the bucket ... and the river was flowing pretty fast and it pulled the bucket back and one of the ropes hooked around the back of his skid and he couldn't keep up with it."
