Harness Integrity

Recommended Posts

You will have a hard time finding statistics about harness failures because they are so rare.
Harnesses are so hopelessly over-engineered that errors in donning are more common than harness failures.
There was one case of a hip joint flipped through that popped a few stitches.
Other manufacturers suffered a few fatalities when people mis-threaded chest strap buckles.
In the 3 years that I specialized in harness repairs - at Rigging Innovations - we saw few damaged harnesses, none of them fatal.
Several harnesses were damaged (bent hip rings and popped stitches) by hard openings caused by sloppy packing of ZP mains, right after ZP fabric was introduced. In one case, all the owner had to do to solve the problem was switch to smaller rubber bands.
We also had to repair several harnesses that students dragged the length of taxiways.
... and there was always the usual wear and tear caused by thousands of jumps in the desert.

The only death due do harness failure in recent memory is the student who died after a Student Javelin's adjustable MLW opened all the way up, snapping their neck with the chest strap(IIRC).

The only failure I've seen was video of a friend's rig after of the stitching failed while jumping at Quincy. This was back before I was a rigger so I couldn't say what caused it, or what rig type. I never saw the rig in person because since it was at the WFFC, the jumper just left it with the manufactuer.

While he was a large jumper who had a Sabre opening on an old rig, I suspect there was some substance that got on the stitching thus weakening it to the point of failure.
