1. Letter Howe-204-79, Enclosure 1, Item C2 outlined a supplier quality

' verification documentation review program, the purpose of which is to detect nonconfoming conditions in the data packages such as those given as examples in the 79-12 report. The progrem neither requires a review of an (100%) quality verification documents nor calls for a review of Engineering documents. A sampling plan derived from MIL-STD-105D is used to determine if a given supplier's quality veri-fication documents should be classified as " good" or " indeterminate."

If a supplier's documents are classified as good, then a reduced sampling plan vill be used to over-inspect the documentation packages and the effectiveness of the primary inspection conducted in the course of the normal procurement process. If a supplier's docu=ents are given an indeterminate classification, then all quality verification docu=ents from that supplier vill be subject to the over-incpection.

2. Letter Hove-204-79, Enclosure 1, Item C2a stated that Bechtel's Procurement Supplier Quality Organization was requested to conduct a fomal review of valve documentation packages to assure compliance with the requirement for the docu=entation of vall thickness measurements.

This review has been completed. Seventy-five documentation packages from four purchase orders to Westinghouse (1), Target Rock (1) and Henry Pratt (2) were reviewed. All contained the required vall thickness measurements. The purchase order for which Borg Warner supplied valves (7220-M-1293), as of the date of the revier, had documentation submitted for 223 valves, but vall thickness reports were submitted for only 126 valves. Corrective action to obtain the missing documentation has been initiated. It is concluded that this problem is unique to Borg Warner and not limited to the documentation package in which the discrepancy was initially identified.
