Woman escapes NSW plane dive unscathed

A light plane has nosedived into trees in Sydney's south-west, with paramedics saying it's a "miracle" the pilot walked from the wreckage with only a sore back.

The woman in her 50s was the only person aboard the plane when it crashed at Bankstown Airport at about 11.20am on Monday.

The plane landed among trees in the ditch at the edge of a paddock, images shared by emergency services show.

The pilot walked away from the aircraft with help from airport staff before being assessed by paramedics.

NSW Ambulance Inspector Andrew Keshwan said his team had "expected the worst" but were relieved to find the woman was uninjured.

She complained of a sore lower back but did not need to be taken to hospital.

"This is a very happy and lucky outcome for the pilot," Mr Keshwan said in a statement on Monday afternoon.

"It is a miracle she has walked away from the wreckage without any injuries."

The Australian Transport and Safety Bureau says it will decide on Tuesday whether to investigate the crash.
