As per my telephone message on Tuesday, January 17, 2012, I realized on the previous business day (Friday, January 13, 2011) that my memory was incorrect as to the description I provided in our report of January 11, 2011. I had described the cracks in the elements as "these cracks may be in a non-fuel area." Upon re-examination of the video and pictures on Friday, I would like to submit a more complete and accurate description of the elements, below: SIN 2281 Instrumented Element: | As per my telephone message on Tuesday, January 17, 2012, I realized on the previous business day (Friday, January 13, 2011) that my memory was incorrect as to the description I provided in our report of January 11, 2011.

Dear Mr. Traiforos:
As per my telephone message on Tuesday, January 17, 2012, I realized on the previous business day (Friday, January 13, 2011) that my memory was incorrect as to the description I provided in our report of January 11, 2011. I had described the cracks in the elements as "these cracks may be in a non-fuel area." Upon re-examination of the video and pictures on Friday, I would like to submit a more complete and accurate description of the elements, below: SIN 2281 Instrumented Element: Discolored, multiple blisters in the upper non-fuel section. Y -shaped crack in the upper fourth of the fuel section. Continuous vertical, longitudinal crack in the lower two-thirds of the fuel section. 0% of the element can be lifted with a tool. SIN 590E: Discolored, blister on the bottom ring of the element. Three separate vertical cracks on the same side: (starting from the bottom of the element) #1 in the lower fourth ofthe fuel region; #2 starts to the right ofthe first crack just before the first crack ends, about the same length as the first crack; #3 starts to the left of the second crack and just before the second crack ends, about three times the length of the other two cracks. This element can be pulled about 20% out with a tool. SIN 623E: Discolored, very light colored crack in the upper section of the non-fuel region. Cracks in the other elements are very dark, so this one may be just beginning.
This element can be pulled about 25% out with a tool. SIN 1201E: Discolored, almost straight vertical longitudinal crack along the middle section of the fuel region. The crack extends about 80% of the fuel region. This element can be pulled about one inch with a tool. Page 1 of2 A subsidiary of Autoliv ASP, INC.
