Visual analysis of the failed component suggests that there would likely have been visible cracking of the part well before the failure that resulted in this incident.Such cracking would be obvious to a user complying with the instructions in the device manual to periodically inspect the device for cracks.The product manual instructions say: "to prevent structural failure, which may result in serious injury or death: inspect this product and accessories regularly for loose or missing screws, metal fatigue, cracks, broken welds, missing attachments, general instability or other signs of excessive wear.Immediately remove this product from use when any condition develops that might make operation unsafe.".
