Engine failure reportedly prompted the landing on the narrow Stanwell-Waroula Road, near the Capricorn Highway about 25 kilometres south west of Rockhampton, at 9.45am.

There are conflicting reports of how many people were on board but it is believed to be between two and four.

The plane landed safely and all escaped uninjured.

Channel 7 has named the pilots as Sarah and Fred Hughes.

An employee of the nearby Stanwell Stop service station said she was on her way to work when she came across the scene.

"It's just a little, narrow road that goes past the shop," she said.

"It's just a tiny little plane, I saw it ahead then I had to drive under the wings to get past and get to work.

"I said to the boss when I got here, 'gee you see some strange things on country roads. Coming to work I just had to drive under the wing of a plane parked on the road."

The shop employee, who declined to be named, said it appeared to have landed without incident.

"One gentlemen I spoke to said he heard it spluttering as it passed over his house," she said.

"There didn't seem to be any damage to the plane, it just came down and landed on the road.

"There were three guys and a young woman there, they were all fine, walking around the plane talking on their mobiles.

"Thank God there were no trees or anything there." 

Police, ambulance and fire rescue crews attended the scene but the pilot and passengers were not injured.
