Pin Out on Exit
Although this jumper received a pin check a few minutes prior to exiting, his pin came loose prematurely, and he opened in a head-down position about six seconds after leaving the plane. Fortunately, he and the other jumper were unhurt by the premature deployment.
It is unclear what happened to make the pin come loose, but the jumper most likely rubbed the back of his container against the door frame during the exit. Jumpers need to plan and execute exits that allow for everyone to leave the aircraft without their gear coming into contact with any part of the door frame. Additionally, although it’s unknown whether this jumper’s closing loop was snug, a tight main closing loop can help to keep the main pin secure in the event there is contact with the airplane or another jumper during exit.
