Preventing kill-line burns on top of a canopy in Gear and Rigging October 23, 2011 If you go to the one that is "completely enclosed' you must be very very vigilant. As you cock the pilot chute, it wrinkles the part of the bridle inside the bag. So far so good. Good in theory. But...those wrinkles have an obvious tendency to straighten, which reverses the cocking you just put into it...leaving you to be (a bit o' humor here) half cocked. You must be sooo...vigiliant to prevent this. I know of a cutaway because of this. Pilot chute was not sufficiently inflated, as the kill line was half extracted. I watched him pack the next pack job and he could not keep it cocked, as the bridle was new, and stiff. Those wrinkles would not stay wrinkled. In fact, they were more like a spring. He switched.
