"Docket No. FAA-2010-0562; Directorate Identifier 2009-NE-29-AD'' Para (e)(2) of the Proposed Amendment to 14 CFR Part 39 states under 'Actions and Compliance' that: "Thereafter at every engine shop visit, perform the inspection specified by paragraph (e)(1) of this AD." This compliance statement would force the HP Rotor to be piece parted at every shop visit, regardless of whether the engine is inducted for minor repair or full overhaul. The EASA AD intent is that the inspection should be carried out only when the engine is in shop for Refurbishment (level 3) or Full Overhaul (level 4) i.e. when the HP rotor is already piece parted. Is it the FAA intent to force a Level 3/4 workscope (in order to piece part the HP Rotor so that the inspection can be accomplished) of the HP module at EVERY shop visit, or should the proposed AD reflect the EASA AD and Rolls Royce SB?
