Requires a one-time recalculation of the remaining service life of each affected high-pressure (HP) turbine disc and HP blade and, depending on the results, replacement with a serviceable part. Prompted by a manufacturing non-conformity of the HP turbine blades that was identified through quality control on a batch of blades during production. This non-conformity affects the service life of the affected blades and HP disk where the blades are installed and, consequently, of the modules M02 on which these blades are installed.
