We shared this photo on our Facebook page yesterday, which sparked a great deal of discussion and comments. Some of them spot on, some of them incorrect or based on misunderstandings of what is going on.
The container in question is a Vector, so we contacted UPT to get some advice and tips specific to this rig straight from the manufacturer. Below is their response.
“We are happy to hear that the jumper landed uneventful after the pilot chute in tow!
Here are our observations from the photo:
The main side flap location and grommet offset is correct.
The UPT Vector 3 container is designed and constructed to have the top 2 main grommets offset. This allows a low profile and better pin protection, allows the main pin cover to close correctly, and cosmetically the container will look as designed. The correct offset is as pictured, with the binding tapes stacked touching the edge of the grommet.
The main bridle routing is not as per current UPT recommendations
UPT recommends routing the main bridle from the bottom up. What is pictured is the alternate older routing. The change was made in an effort to reduce the risk of bridle piercing.
Closing loop tension is unknown
When packing and/or jumping the container, care must always be taken to ensure that loop tension is sufficient to not allow the main closing pin to accidentally dislodge. Proper loop length, proper canopy configuration, and attention towards storage and use, all play into this matter.
It appears that the eye of the main pin has become trapped inside the main closing loop, from one of the following hypothetical scenarios:
- Accidentally pushing the pin too far through the main loop during closing of the container.
This has been observed and reported on rare occasions in the past, and has generally been caught on pre-jump inspections of the gear
- Excess bridle incorrectly routed under the main pin, causing the pin to instantly flip to a standing position during deployment which allows the main loop to slide over the eye. This is a very unlikely scenario, although possible in theory and with some practical application.
Either scenario is preventable by utilizing correct methods during packing, and performing gear checks prior to jumping.
Please refer to the Vector 3 container manual p. 60-61 for current main closing method and bridle routing for the Vector 3 container.
