Had a situation not long ago. One of my fellow co-workers was doing a manual engine start on a B767 fitted with PW4060 engines. As the signal was given to close the start valve, for some reason the pilot throttled up. It was enough to start draging him forward towards the intake. Fortunately he had the presents of mind to grab onto the rear edge of the reverser cowl. He was literally swept off his feet. Fortunately, his partner on the headset told the crew to shutdown, not just throttle back. This I believe saved his life. I don`t know how long he would have been able to hold on.
We work in a dangerous enviroment, and we sometimes become complacent. My deepest regrets for the family.
