A Piper PA-42 Cheyenne ran off of RDU's General Aviation runway around 4 a.m.
According to Andrew Sawyer at RDU, the plane stopped in the grass and mud at the end of the short airstrip.
When the pilot tried to turn the plane around in the grass, it clipped one of the blue lights along the runway.
Two people were on board the twin-engine plane, but they were not injured.
Because of the time when the incident occured, there was no stoppage in air traffic and the runways remained open.
Officials said wet weather may have been to blame, but they are still trying to determine the cause of the incident.
