A 37-year-old man who taxied his light plane down the main street in the WA Pilbara town of Newman and parked it at a pub has been fined.

Anthony Philip Whiteway pleaded guilty in the Newman Magistrates Court to committing an act likely to endanger the life, health or safety of a person.

The plane had no wings, but its propeller had been running when it was taxied down the street earlier this month.

Mr Whiteway had just bought the aircraft and was taking it home when he stopped at the Newman Hotel.

Police said there was an exposed fuel line hanging from the side of the plane that was attached to an insecure jerry-can inside the cabin to enable the engine to run.

They said Mr Whiteway, who does not hold a pilot's licence, left the engine in a potentially dangerous condition with the ignition on.

He was fined $5,000 plus court and towage costs.

Mr Whiteway said he was keen to restore the plane once it was returned to him by police.

But he said the wingless plane would not be taken to the pub again anytime soon.

"I don't think I'll be taking it to the pub again, no," he told the ABC.

He also said despite rumours, he was not looking to sell his aircraft.

Sergeant Mark Garner said police were happy with the outcome.

"The potential for damage had [the propeller] struck someone, or something else happened, was pretty serious," he said.

"I appreciate there's a lighter side of this story, but the concern is it did present a real danger to other motorists and pedestrians in what is quite a busy town.

"The obvious message is don't drive your plane down the street."
