Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

all Rolls-Royce plc (RR) RB211 Trent 

500 series turbofan engines. That AD 

currently requires a one-time inspection 

of the fuel tubes and fuel tube clips for 

evidence of damage, wear, and fuel 

leakage. This AD requires the same 

inspection, and adds additional 

repetitive inspections. This AD was 

prompted by additional RR engineering 

analysis. We are issuing this AD to 

prevent engine fuel leaks, which could 

result in engine damage and damage to 

the airplane. 

DATES: This AD is effective April 5, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 5, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

On January 19, 2012, we issued AD 

2012–02–04, Amendment 39–16927 (77 

FR 6668, February 9, 2012), for all RR 

RB211 Trent 500 series turbofan 

engines. That AD requires a one-time 

inspection of the fuel tubes and fuel 

tube clips for evidence of damage, wear, 

and fuel leakage. That AD resulted from 

reports of wear found between the 

securing clips and the low-pressure (LP) 

fuel tube outer surface, which reduces 

the fuel tube wall thickness, leading to 

fracture of the fuel tube and consequent 

fuel leakage. We issued that AD to 

prevent engine fuel leaks, which could 

result in engine damage and damage to 

the airplane. 

Actions Since AD Was Issued 

Since we issued AD 2012–02–04, 

Amendment 39–16927 (77 FR 6668, 

February 9, 2012), RR engineering 

determined that additional repetitive 

inspections are required. The European 

Aviation Safety Agency (EASA) has 

notified us of this unsafe condition and 

corrective actions in EASA AD 2012– 

0237R1, dated November 14, 2012. 

Relevant Service Information 

We reviewed RR Alert NonModification Service Bulletin (NMSB) 

RB.211–73–AG948, dated September 28, 

2012. The NMSB describes procedures 

for inspection and possible removal and 

replacement of the LP fuel tubes, fuel 


wreier-aviles on DSK5TPTVN1PROD with RULES
17298 Federal Register / Vol. 78, No. 55 / Thursday, March 21, 2013 / Rules and Regulations 

tube clips, and fuel-to-oil heat 

exchanger mounts. 

FAA’s Determination 

We are issuing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

AD Requirements 

This AD requires a one-time 

inspection, and additional repetitive 

inspections of the fuel tubes, fuel tube 

clips, and fuel-to-oil heat exchanger 

mounts for evidence of damage, wear, 

and fuel leakage. 

FAA’s Justification and Determination 

of the Effective Date 

The FAA has found that notice and 

comment prior to adoption of this rule 

is unnecessary because no engines are 

used on U.S. registered airplanes. 

Therefore, we find that good cause 

exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not provide you with notice and 

an opportunity to provide your 

comments before it becomes effective. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2012–0004 and directorate 

identifier 2012–NE–01–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 we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD will not 

affect any engines installed on airplanes 

of U.S. registry. Therefore, we estimate 

the cost of this AD to U.S. operators to 

be $0. 

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 

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 

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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends part 39 of the Federal 

Aviation Regulations (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 

removing airworthiness directive (AD) 

2012–02–04, Amendment 39–16927 (77 

FR 6668, February 9, 2012) and adding 

the following new AD: 

2013–05–18 Rolls-Royce plc: Amendment 

39–17390; Docket No. FAA–2012–0004; 

Directorate Identifier 2012–NE–01–AD. 

(a) Effective Date 

This AD is effective April 5, 2013. 

(b) Affected ADs 

This AD supersedes AD 2012–02–04, 

Amendment 39–16927 (77 FR 6668, February 

9, 2012). 

(c) Applicability 

This AD applies to Rolls-Royce plc (RR) 

RB211 Trent 553–61, RB211 Trent 553A2–61, 

RB211 Trent 556–61, RB211 Trent 556A2–61, 

RB211 Trent 556B–61, RB211 Trent 556B2– 

61, RB211 Trent 560–61, and RB211 Trent 

560A2–61 turbofan engines that have any of 

the following fuel tube part numbers 

installed: FW57605, FW17689, FW57604, 

FK30710, FW57578, or FK30713. 

(d) Unsafe Condition 

This AD was prompted by reports of wear 

found between the securing clips and the 

low-pressure (LP) fuel tube outer surface, 

which reduces the fuel tube wall thickness, 

leading to fracture of the fuel tube and 

consequent fuel leakage. We are issuing this 

AD to prevent engine fuel leaks, which could 

result in engine damage and damage to the 

airplane. 

(e) Actions and Compliance 

Unless already done, do the following 

actions. 

(1) Inspect the LP fuel system of engines 

that are on wing within 1,600 flight hours 

after February 24, 2012, or before the next 

flight after the effective date of this AD, 

whichever occurs later. Use the procedures 

in the Accomplishment Instructions, 

paragraph 3.A, of RR Alert Non-Modification 

Service Bulletin (NMSB) RB.211–73–AG948, 

dated September 28, 2012, to do the 

inspection. 

(2) For engines that are in shop for any 

reason, after the effective date of this AD, 

inspect the LP fuel system. Use the 

procedures in the Accomplishment 

Instructions, paragraph 3.B, of RR Alert 

NMSB RB.211–73–AG948, dated September 

28, 2012, to do the inspection. 

(3) Thereafter, reinspect the LP fuel system 

within every 6,000 flight hours since last 

inspection. Reinspection may be on-wing or 

in the shop. Use the procedures in the 

Accomplishment Instructions, paragraph 3.A 

or 3.B, as appropriate, of RR Alert NMSB 

RB.211–73–AG948, dated September 28, 

2012, to do the inspection. 

(4) If the LP fuel system fails the 

inspections required by this AD, replace the 

part(s) that failed the inspection with 

hardware eligible for installation. 

(f) Definitions 

For the purpose of this AD, a shop visit is 

the induction of an engine into the shop for 

maintenance or overhaul. The separation of 

engine flanges solely for the purposes of 

transporting the engine without subsequent 

engine maintenance does not constitute an 

engine shop visit.
