[Docket No. FAA-2007-28059; Directorate Identifier 2007-NE-13-AD] 

RIN 2120-AA64 

Airworthiness Directives; Rolls-Royce plc Turbofan Engines 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking (NPRM). 

SUMMARY: We propose to supersede an existing airworthiness directive (AD) for all 

DATE 

3/8/ 13 

Rolls-Royce plc (RR) RB211-Trent 553-61 , 553A2-61, 556-61, 556A2-61, 556B-61 , 

55682-61,560-61 , 560A2-61, 768-60,772-60, 7728-60, 875-17,877-17,884-17, 884B-b::rn~AL"""';-;c- G - + 

17, 892-17, 892B-17, and 895-17 turbofan engines. The existing AD currently requires 

inspection of the intermediate-pressure (IP) compressor rotor shaft rear balance land for 

NE-lli 

cracks. Since we issued that AD, a crack was detected in a Trent 500 IP compressor roto INlTIALs/srG 

shaft rear balance land during a shop visit, and further engineering evaluation done by 

RR concluded that the cracking may also exist in Trent 900 engines. This proposed AD 

would require inspections of the IP compressor rotor shaft as required by the existing A .._...,=""""":---twhile adding tepstiti~n-wing inspections for the Trent 500 engines, and on-wing and 

in-shop inspections for the Trent 900 engines. We are proposing this AD to detect 

cracking on the IP compressor rotor shaft rear balance land, which could lead to 

uncontained engine failure 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:
