Human Factors; Aircraft
The passengers were coming onto the aircraft. One gentleman was looking down as he was coming up the stairs and he was also wearing a baseball cap. When he got to the top stair; he popped upright and stood up directly into the airstair door frame and hit his head. He did not injure himself and he was able to turn his head to the side to see the entryway and get into the aircraft. He went to his seat. When leaving the aircraft; when I said to watch his head; he said 'yes; I've learned that lesson.' Cause: Low clearance when entering the aircraft from the stairs and his baseball cap limited his visibility; as well as his looking down as he was climbing the stairs.
DHC8-100 Flight Attendant describes another passenger head collision with the top of the door frame while boarding.
