JasonF took some photos before he died intending to prepare a post regarding packing technique and line overs. I’m going to do my best to convey the essence of his intended message.
During one of the early Petronas events in Malaysia, several people had partial line overs that cleared on opening (thanks go to Annie for filming these and pointing them out to the people involved). Jason was one of these people who had a self-clearing line over. He spoke to everyone else who had also had a self-clearing line over in an attempt to locate a cause. Over the years, Jason critically analysed the way he packed in an effort to reduce the chance of slider-up line overs. At the most recent event, there were again several people who had self-clearing line overs. Jason spoke to them and examined their packing techniques. He concluded that they were all missing a crucial step in their pack-job. Hence, Jason came up with the following suggestion.
The attached photo shows the left-hand side and right-hand side of a pack job flaked slightly differently. On the left-hand side, the first stabiliser fold has been consciously pulled out and the brake lines pulled in towards the middle of the pack-job. The brake line on the left-hand side is now significantly impeded from leaving the middle of the pack-job during deployment. However, on the right-hand side, the stabiliser was not pulled out when the three outer cells were folded in. The result is that the stabiliser on the right-hand side is now hidden, and the brake line’s movement is less restricted. Jason believed that ensuring the stabiliser was pulled out, and that the brake lines were pulled in to the middle of the pack-job was important to avoid line overs.
Logically, having the stabiliser pulled further out - and the brake lines further in - makes it much less likely that the brake lines will end up on the wrong side of the stabiliser when it inflates. Some of the other people who had self-clearing line overs in Malaysia had some of the most anally retentive packing techniques I’ve ever seen (sorry Ray), so sloppy packing can easily be ruled out as a possible cause. Since changing his packing technique, Jason has never observed another self-clearing line over on footage of his jumps.
Something to think about…
