14 CFR Part 39 

[Docket No. F AA-2013-0052; Directorate Identifier 2013-NE-02-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 adopt a new airworthiness directive (AD) for all RollsRoyce plc (RR) RB211-535E4-37, RB211-535E4-B-37, RB211-535E4-C-37, and 

RB211-535E4-B-75 turbofan engines. This proposed AD was prompted by RR updating 

the low-cycle-fatigue life analysis for the low pressure turbine (LPT) stage 2 discs. This 

proposed AD would require removal of affected parts using a drawdown plan. We are 

proposing this AD to prevent LPT stage 2 disc failure, which could result in uncontained 

engine damage 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 by any ofthe following methods: 

• Federal eRulemaking Portal: Go to http://www.regulations.gov and follow the 

instructions for sending your comments electronically.
