During an indoor training session the reserve connection handle of a Wings of Change MG1 Harness failed. The handle became detached from the connecting loop during an attempted deployment. (see picture 1.)
On examination, the failure was due to incorrect sewing at the handle-connection loop attachment point. Normally the sewing pattern should be three rows of stitching approximately 10-15mm from the end of the connecting loop (red circle, picture 2), near to the Velcro attachment on the handle. In the case of the failed handle, only one row of stitching was partially present, approximately 2mm from the end of the connecting loop, which resulted in detachment under load (picture 3).
