Although the visible deformation on this barrel-type quick link (aka a “French connector” or “Rapide link”) occurred on a tandem system, skydivers should know that it can happen under the same circumstances on any rig that uses this type of link. This rig had about 50 jumps on it since the links—which connect the risers to the lines—had been installed after the canopy underwent a relining.
After landing from a routine jump, the tandem instructor discovered this damage and that several of the canopy’s suspension lines had come off the connector link, which had loosened enough to disconnect entirely. Fortunately, the lines did not come off the link in air, which could have been catastrophic.
A subsequent examination by a rigger showed that the other three barrel connectors were only finger-tightened, and some were partially undone. This indicates that the connector was not correctly tightened after the relining and may also indicate that the staff had not adequately performed the 25-jump inspections as required by the manufacturer.
A barrel-type quick link should be fastened firmly but not excessively tightly. Common torque settings (usually found in the harness-and-container manufacturer’s manual) are generally between 5 and 10 pounds per inch, depending on the connector type and manufacturer. Those without access to a torque wrench or whose manuals don’t specify a torque, can hand tighten and then made an additional ¼ turn with a wrench as recommended by Dan Poynter in “The Parachute Manual.” Poynter also recommends rechecking the connectors after 10 jumps and retightening if necessary. A certified rigger can also assist in setting the appropriate torque if you’re uncertain.
Loose connectors can lead to equipment failure, making it essential for skydivers, riggers and instructors to check at regular intervals that all links are correctly tightened and secure. This incident is a good reminder of how crucial it is to regularly inspect every component of a parachute system.
