Please consider clarification of Para (i) (optional terminating action) as follows: 1/ This section states that accomplishment of repetitive USI per Para (h)(1) and (h)(2) eliminates the cleaning and inspection requirements of this AD. Please add clarification that the "cleaning and inspection requirements" referred to are those listed in Para (g), if that is the intent. 2/ Please clarify that installation of a zero-time HPC stage 3 to 8 drum that has never operated with silver plated nuts (per Para (i)(2)) terminates the requirement for initial USI inspection per Para (f) and removal of fully silver plated nuts per Para (g). While this can be assumed it is not clearly stated. Please consider the addition of a section to Para (k) (Previous Credit) as follows: 1/ As per item 2/ above state that prior installation of a zero-time HPC stage 3 to 8 drum that has never operated with silver plated nuts removes the unsafe condition and therefore action per Para (f) through (h) is not required.
