### Version 3.2 (4/17/13) [4910-13-P] DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2010-0562; Directorate Identifier 2009-NE-29-AD] RIN 2120-AA64 Airworthiness Directives; Rolls-Royce pic Turbofan Engines AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: We propose to supersede an existing airworthiness directive (AD) that applies to all Rolls-Royce pic (RR) model RB211 Trent 553-61 , 553A2-61, 556-61 , 556A2-61, 556B-61 , 556B2-61, 560-61, and 560A2-61; and RB211 Trent 768-60,772- 60 , and 772B-60; and RB211-Trent 875-17,877-17,884-17 , 884B-17, 892-17, 892B-17, and 895-17; and RB211-524G2-T-19, -52403-T-19, -524H-T-36, and -524H2-T-19 turbofan engines that have a high-pressure (HP) compressor stage 1 to 4 rotor disc installed, with a certain part number (PIN) installed. The existing AD requires repetitive ' 

### inspections of the axial dovetail slots, and follow-on corrective action depending on findings. This proposed AD expands the population of affected parts. This proposed AD also changes, for the purposes ofthis AD, the definition of"engine shop visit." We are proposing this AD to detect cracks in the HP compressor stage 1 and 2 disc posts, which could result in failure of the disc post and HP compressor blades, damage to the engine, and damage to the airplane. DATES: We must receive comments on this proposed AD by [INSERT DATE 60 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any ofthe following methods: ONCURRE NCES ROUTING SYMBOL ANE-110
