Jumpers blame the occurrence of twisted steering lines on everything from how they collapsed their canopies to the Coriolis effect. But no matter how they occur, if left unattended, they can lead to problems. It does not take many twists before lines start wearing unevenly.

A jumper experienced broken suspension lines on his new main parachute that required him to cut away and deploy his reserve. Later, when investigators inspected the main parachute, they determined that tension knots, which most likely developed in the jumper’s semi-stowless deployment bag, caused one line to saw through the other lines. Jumpers must carefully fold suspension lines into the pouch of a semi-stowless bag to allow the lines to pull free in an orderly manner.

A senior parachute rigger received this harness and container for some work, and when he closed the rig following the repairs, he discovered that the main closing loop was more than two inches too long. The main closing pin had no tension on it at all in this configuration. He shortened the loop to the correct length and helped the owner of the rig understand why it is essential for everyone in the airplane and on the skydive to have the proper tension on the closing pin to prevent an inadvertent container opening.
