| Title | Uci Terminal Boxes P/N 005650-01 Discoloration and Corrosion |
| Event Description | The following information is excerpted from an email submitted by the reporting organization:
In July of 2016, UCI [United Controls International] identified extensive discoloration and corrosion on P/N: 005650-01, terminal box enclosures, that were fabricated under UCI's Quality Assurance Program in April of 2015. The identified discoloration and corrosion was not present at the completion of fabrication and became evident when pulled from stock in July of 2016. It was determined that the fabrication process was changed during fabrication of the April of 2015 items to utilize a different vendor for fabrication activities. Evaluation of the fabrication process performed on the subject items identified that this new vendor utilized a polishing process that was not performed on previously fabricated items. Particles/crystals from the discolored areas of the affect items were analyzed by Fourier Transform Infra-Red (FTIR) method and it was identified that ammonium phosphate crystals had formed on the items. It is the determination of UCI that the affected items were cleaned/polished with unknown chemicals during the polishing process of fabrication that resulted in the formation of these crystals and degradation of the enclosure material overtime. The items manufactured utilizing this new process were supplied to Clyde Union Limited under purchase orders 4500109863/4 (Qty. 1) and 4500113688/4 (Qty. 1). Clyde Union Limited was notified of the subject issue on January 13, 2017 and UCI is awaiting concurrence from Clyde Union Limited that the affected items are to be returned for replacement items manufactured per the original manufacturing process.
