Metal fragments were found in the milled bone used for spinal fusion surgeries. ESi’s in-depth metallurgical and design analysis cleared the OEM of breach of contract and anti-competitive practice lawsuits.
The results of ESi’s investigation were used to recommend and substantiate to the USAF Technical Airworthiness Authority (TAA) a return to pressurized flight without altitude restrictions.
Based on the results and findings of this multi-component failure analysis, the client was able to remedy the problems with the new machinery design by addressing the weld defect and successfully launch the new product line.
