Pursuant to 10 CFR 21.21(a)(2), Fisher Controls International LLC (Fisher) is providing the required written final notification of a possible deviation or failure to comply.
On December 13, 2011, Fisher provided an interim notification of a possible deviation or failure to comply concerning a possible issue with the disc pin engagement of a 20 inch Type A 11 butterfly valve, serial number 19102243. The affected valve was returned to Fisher for evaluation and correction and, upon correction, was returned to the customer on November 21, 2011.
