This is sad. You've got to treat these props like they're loaded!
As I posted in a different thread, while I was in Windhoek, Namibia just last year, I watched a guy doing his walk around on a C206. With passengers on board he pulled the prop through. One loud "pop" as a cylinder fired and he dropped like a sack of potatoes. That prop dug in about 3.5" on the right side of his skull leaving a 8" gash. After restarting his heart and stopping the bleeding, all I could do was wait for the ambulance that had to travel 25km.
Anywhere in the U.S. he might have lived (no discussion about his quality of life); in Africa...no way. He was 26yoa, 3 months on the job.
