Narrative:

We were boarding flight. It was raining. I was standing outside the air stair overseeing the boarding process. Eight of the nine passengers were already on-board the aircraft. The last passenger walked out to the aircraft with an umbrella and declined my offer to take the umbrella. The passenger then entered the aircraft and turned around and threw the open umbrella out the door. The umbrella was caught by a gust of wind and blew underneath the aircraft. I yelled at captain and motioned for him to shut down the number two engine; which he did. The umbrella then flew into the still spinning propeller; causing minor damage to the propeller and to the right side of the fuselage due to the flying debris/umbrella pieces. We should make sure that both engines are shut down during the entire boarding process any time it is raining or anytime the crew or ramp personal deems that there is a safety concern.
