Helicopter pilot makes emergency landing with own family on board.

A helicopter pilot and his family of four have survived an emergency landing in heavy bushland in Sydney’s Royal National Park at Bundeena.

The chopper experienced engine failure mid-flight in Sydney’s south this morning.

The family, including a three-year-old boy, were uninjured but had to be winched from the site by the Westpac Lifesaver Rescue Helicopter.

CEO Stephen Leahy said the landing was “remarkable”.

“The pilot has done an incredible job, he’s been flying off shore so he’s been over water with his family on board,” he said.

“He has been able to nurse the helicopter over land and done a very good landing over very thick scrub without injuring anyone.

“He’s done really, really well. No person on board the helicopter has been injured.”

The pilot is being interviewed by police as part of an investigation into what went wrong.
