3Q/08: Risk Cap Invoked. An evaluation revealed an incorrect failure classification in October, 2005. Historical data was corrected with no change in color.
2Q/08: Risk Cap Invoked.
2Q/07: UAI 1.9E-08 / URI -1.6E-07/0 for March '07 revised to: UAI 2.0E-08 / URI 9.0E-09/0 as a result of 1.95 hours unplanned unavailability charged against U-2 Train-2 EDG on 03-18-07 due to lifting an incorrect lead during 2-PT-83.4.1.
