A senior parachute rigger discovered this incorrectly closed reserve container during a gear check of another jumper. The reserve ripcord was on the wrong side of the grommet, and the reserve closing pin was flipped opposite of the correct orientation.

A jumper flying her wingsuit attempted to deploy her main canopy at 3,500 feet. A few seconds after she threw her pilot chute, she saw the pilot chute trailing behind her, so she pulled her reserve ripcord. The reserve deployed and was fully inflated by 2,000 feet. The main canopy remained in the container after the reserve deployed.

This bag-lock malfunction occurred when one of the packing tabs on the canopy entangled with the last closing-stow band on the deployment bag. Although this is a very unusual malfunction, jumpers can help avoid it by making sure that the stows are not near the packing tabs when closing their deployment bags. 

While opening a container to start a reserve repack, a Federal Aviation Administration Senior Rigger found that the reserve ripcord was positioned on the top-reserve-flap grommet, pressed between the pin and the top of the grommet.
