I\'ve always done liferaft rigs with the dummy bottles. Most were in rig, but there were a few that were out of tolerance.
I seem to remember a bunch of TCTO\'s on the life raft system in the late 1980\'s, when we had the two or three inadvertant deployments (one of which was a bird from our unit at Kirtland). I also remember that something was done to the cables that might possibly throw the rigging off.
Another thing that just popped into my mind-the cable configuration changed model to model, and it almost seems from year to year. The job guides don\'t cover all the models, IIRC, because I had to go to the old -2 maintenance manuals to rig the liferafts on a 1968 FY model bird.
