Plane crashes in suburban Sydney

A light plane carrying two people and a dog has crashed in a street in Sydney's west.

The plane brought down power lines and disrupted traffic when it crashed in Brenan Street, alongside Brenan Park in Smithfield, about 2.30pm NZT.

Police say they found the single-engine aircraft on its roof after it crashed 350 metres from St Gertrude's Catholic Primary School.

A man and a woman, possibly aged in their 20s, and a dog travelling on the plane were uninjured and managed to get out of the aircraft.

Paramedics said the people suffered minor injuries and were taken by ambulance to Liverpool Hospital in a stable condition.

The aircraft had extensive damage and brought down powerlines, causing localised power disruptions.

Brenan Street is currently closed to all traffic between the Cumberland Highway and Bourke Street.

At this stage, the cause of the crash is unknown.

Joe Porley, manager of Brenan Tennis Centre in Brenan Park, said the plane came to rest near the front fence of a house.

"The plane could have very easily have gone through someone's house," he told AAP.

"Someone may have been hurt. I think it's lucky that it's ended up where it has ended up. From the way it's positioned, it looks like it landed on the street."
