| Title | Part 21- Potential Defect in a Socket Used Separately or in a Connector Kit |
| Event Description | The following information was received by facsimile:
[The Curtiss-Wright] letter is issued to provide notification of a potential defect in Socket (PIN: GB-1 A-5) sold separately or supplied as part of a GRAYBOOT 'A (GB-1A) Connector Kit. There is one affected lot of Sockets (Lot#: 092413). The potential defect is that the socket was not zone annealed which will possibly affect the ability to crimp the socket onto the wire conductor. Zone annealing is specified for the crimp barrel to return the crimp barrel to a soft condition to counteract the effects of previous heat treating required to develop spring tension in the socket tines that mate with the pin contact. The nine affected Customers and their associated Purchase Orders are listed below. All Customers will be notified by February 24, 2015 and supplied with the information we have at this time. 1. Vattenfall- Forsmark Kraftgrupp AB, P.O. 4500301916 2. Vattenfall- Forsmark Kraftgrupp AB, P.O. 4500301916 3. Decon International (HK) Ltd., P.O. DIL00590 4. Ringhals AB, P.O. 641511-090 5. Dremel Inc., P.O.13-040 6. Bruce Power L.P., P.O. 00185336 7. Kanata Electronic Services Limited, P.O. 34513 8. Meggitt Safety Systems Inc., P.O. 104057 9. Meggitt Safety Systems Inc., P.O. 104345 Based on our recent in-house testing of socket Lot #: 092413, the defective sockets appear to be more difficult to crimp than sockets that have been zone annealed. Some of the Lot #: 092413 sockets showed cracking or bending under magnification. We did not have any sockets actually break apart during the crimping process. All the test specimens crimp barrels remained intact. If a severe fracture had occurred at the time of crimping we believe it would have been very noticeable to the technician installing the contact. Once crimped, the socket appears to function well by conducting electricity and exhibiting acceptable electrical resistance. Many of these sockets from Lot #: 092413 may already be installed. Customers will need to determine if replacing the sockets is required. All customers listed may choose to replace already installed sockets. It is requested that any uninstalled sockets be returned for replacement. All customers requesting replacement sockets should contact Bambi Rhoades at brhoades@curtisswright.com or by phone at 256-924-7424 for arrangements or Jim Tumlinson, contact information listed below. Send all defective sockets to QualTech NP; 120 West Park Loop; Huntsville, AL 35806. Customer can contact Cindy Tidwell at ctidwell@curtisswright.com or by phone at (256) 924-7436 for help with international or freight collect shipping instructions. Ship all defective sockets collect to UPS Account No. 35254E. Additional details, corrective actions and root causes will be provided once our report of the recent testing complete. If you require additional information or would like to discuss this further please do not hesitate in contacting [Jim Tomlinson; Office Phone: (256) 924-7429; email:jtomlinson@curtisswright.com].
The following report was received via fax: This letter provides for the formal close out of notification QTHuntsville 10CFR21-2015-01. The initial notification was made on February 20, 2015 (NRC Event 50846). All customers were notified and received the test data. All customers were given the opportunity to receive replacement sockets, as they deemed necessary. These replacement parts have been delivered. All actions have been completed. To prevent reoccurrence in the future, the following internal documents have been revised. The procurement and dedication guidelines for both the original GRAYBOOT and GRAYBOOT 'A' connectors were revised. GRAYBOOT 'A' Report No.: SAIC-TR-l038.2-03 currently at Revision P, dated July 16, 2015. GRAYBOOT Report No.: EGS-TR-880708-01 currently at Revision Y, dated July 16, 2015. Both the reports above now contain additional destructive testing as well as visual inspection under magnification to provide more reasonable assurance that the annealing is acceptable. Also, additional training was conducted at our sub-supplier and additional requirements have been added to our purchase orders to prevent any reoccurrence . Based on the above information and corrective actions, this part 21 file is considered closed. If you would like to discuss this further, please contact Tony Gill (QualTech NP Quality Assurance Manager) at 256-924-7438 (office). 256-426-4558 (mobile) or tgill@curtisswright.com.
