This letter provides for the formal closeout of notification 10CFR21-2012-01. The initial notification was made on February 06, 2012. All corrective actions and corrective actions to prevent recurrence have been completed and all affected parts listed on the initial notification have been returned by our customers and replacement items supplied. All affected parts in inventory at our facility were removed and discarded. The initial corrective action was to retrieve all affected parts both in our inventory and those provided to our customers as safety-related. As stated above, all affected parts have been returned and/or retrieved from inventory and discarded. There were four primary root causes identified that allowed the defective items to be manufactured and accepted. The causes are listed below: 1. Mold sections/mold inserts for the two different size plug insulators (regular and oversized) are used in the same mold assembly. Not all required mold parts were removed when changing from the manufacture of oversized to regular boots causing the defective parts to be manufactured. 2. Vendor did not verify the affected dimension prior to shipment of the parts to QualTech. 3. The inspection drawing in the QualTech dedication guidelines was not clear as to the required dimension to be verified. 4. The QualTech Inspector incorrectly interpreted the inspection drawing and verified the wrong dimension thus accepting the defective parts. The corrective actions to prevent recurrence have been completed and include the following: 1. An additional mold was purchased from our supplier to prevent mixing of inserts. Now there are no mold parts utilized in the manufacture of different sized plug insulators (regular vs. oversized). This issue was one of the primary causes of the defect. 2. Notification was made to our supplier and corrective actions implemented at their facility. 3. The QualTech inspection drawing in the affected dedication guidelines was revised to better define the required dimension. 4. The error was discussed with the QualTech Inspector to ensure understanding of the critical dimension. Based on the above information and corrective actions this part 21 file is considered closed. If you would like to discuss this information further please contact the undersigned at 256-722-8500 ext. 131 (office), 256-426-4558 (cell), or tgill@curtisswright.com.
