A Perth man accused of parking his new plane with the ignition on and propeller running outside his local pub has been charged with endangering lives.

The 37-year-old man, who doesn't hold a pilot's licence, was taxiing his newly purchased two-seater Beechcraft aircraft, minus the wings, through Newman's streets on his way home when he decided to stop at the local pub.

However, on stopping the plane he left the ignition on and propeller running, potentially causing danger to people, West Australian police say.

This was about 2pm on October 31 while roads were busy with cars and pedestrians.

An examination of the plane found an exposed fuel line hanging from the side of the plane attached to an insecure jerry can inside the cabin to enable the engine to run, police said.

Newman Police sergeant Mark McKenzie said earlier on Monday that he was stunned by the man's actions.

"It was a pretty stupid thing to do," Sgt McKenzie told AAP.

"Kids were coming home from school. It could have been very ugly.

"All he needed was one gust of wind ... because without the wings, it's not stable.

"People think it was a bit of a laugh, but it was very dangerous and we're not very happy with it."

The man has been charged with endangering life, health or safety of a person and is due to appear at the Newman Magistrates' Court on November 18.
