AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Several instances of fan blade cracking 

have been reported. The results of the 

subsequent technical investigation concluded 

that the cracking was caused by fan blade 

flutter at certain engine settings during 

prolonged ground running. 

This condition, if not corrected, could 

affect the integrity of the fan blades, leading 

to cracking of multiple fan blades and could 

possibly result in engine failure and release 

of uncontained high energy debris. 

We are issuing this AD to prevent fan 

blade flutter, which could result in an 

uncontained engine failure and damage 

to the airplane. 

DATES: This AD becomes effective 

November 29, 2011. 

We must receive comments on this 

AD by December 14, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of Rolls-Royce plc Alert Service Bulletin 

No. RB.211–73–AG054, Revision 2,

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2011–0175, 

dated September 8, 2011 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Several instances of fan blade cracking 

have been reported. The results of the 

subsequent technical investigation concluded 

that the cracking was caused by fan blade 

flutter at certain engine settings during 

prolonged ground running. 

This condition, if not corrected, could 

affect the integrity of the fan blades, leading 

to cracking of multiple fan blades and could 

possibly result in engine failure and release 

of uncontained high energy debris. 

To address this potential unsafe condition, 

Rolls-Royce has developed modified fullauthority fuel controller software in order to 

ensure that the engine cannot experience 

prolonged running on ground at engine 

settings that would potentially jeopardize the 

integrity of the fan blades. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Rolls-Royce plc has issued RollsRoyce plc Alert Service Bulletin No. 

RB.211–73–AG054, Revision 2, dated 

June 29, 2011. The actions described in 

this service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of the United 

Kingdom and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the United 

Kingdom, they have notified us of the 

unsafe condition described in the MCAI 

and service information referenced 

above. We are issuing this AD because 

we evaluated all information provided 

by EASA and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

FAA’s Determination of the Effective 

Date 

Since no domestic operators use this 

product, notice and opportunity for 

public comment before issuing this AD 

are unnecessary. Therefore, we are 

adopting this regulation immediately. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2011–1109; 

Directorate Identifier 2011–NE–33–AD’’ 

at the beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact with FAA 

personnel concerning this AD. Using the 

search function of the Web site, anyone 

can find and read the comments in any 

of our dockets, including, if provided, 

the name of the individual who sent the 

comment (or signed the comment on 

behalf of an association, business, labor 

union, etc.). You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 76, No. 219 / Monday, November 14, 2011 / Rules and Regulations 70337 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 

the States, on the relationship between 

the national government and the States, 

or on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this AD: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2011–23–12 Rolls-Royce plc: Amendment 

39–16863; Docket No. FAA–2011–1109; 

Directorate Identifier 2011–NE–33–AD. 

Effective Date 

(a) This airworthiness directive (AD)

Reason 

(d) This AD results from mandatory 

continuing airworthiness information (MCAI) 

issued by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as: 

Several instances of fan blade cracking have 

been reported. The results of the subsequent 

technical investigation concluded that the 

cracking was caused by fan blade flutter at 

certain engine settings during prolonged 

ground running. 

This condition, if not corrected, could affect 

the integrity of the fan blades, leading to 

cracking of multiple fan blades and could 

possibly result in engine failure and release 

of uncontained high energy debris. 

We are issuing this AD to prevent fan blade 

flutter, which could result in an uncontained 

engine failure and damage to the airplane.
