The SB has been made into an AD note, AD 2012-13-05, dated August 16, 2002, with a 18 month "comply by" date, so the end of the normal compliance period would have been the end of February 2014, unless the operator had been granted an exception by their airworthiness authority. I don't have any real confidence the AD was complied with, they may have been holding it until a heavy maintenance check. Boeing should be keeping track of their operators' maintenance program with an on-site rep and should know. The only way to really tell is to (hopefully) examine the wreckage.
