RIN 3150–AI95 

Regulatory Changes To Implement the 

United States/Australian Agreement for 

Peaceful Nuclear Cooperation; 

Corrections 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Final rule; correcting 

amendments. 

SUMMARY: On November 8, 2011, the 

U.S. Nuclear Regulatory Commission 

(NRC or the Commission) published in 

the Federal Register a final rule (76 FR 

69120) that amended the NRC’s 

regulations to implement the 2010 

‘‘Agreement between the Government of 

Australia and the Government of the 

United States of America Concerning 

Peaceful Uses of Nuclear Energy.’’ The 

present NRC action is necessary to 

relocate a new section added by the 

final rule, and to make a related 

conforming change to the final rule. 

DATES: This correction is effective 

December 20, 2011, and is applicable to 

November 8, 2011, the date the original 

rule became effective.

3667; email: Cindy.Bladey@nrc.gov. 

SUPPLEMENTARY INFORMATION: This 

action corrects the final rule published 

on November 8, 2011 (76 FR 69120). 

Specifically, the new section in Title 10 

of the Code of Federal Regulations (10 

CFR) Part 40 is added as § 40.56 rather 

than § 40.52. This change is necessary 

because 10 CFR 40.52 through 40.55 

were proposed to be added by a 

previous NRC rulemaking (75 FR 43425; 

July 26, 2010) that the NRC now intends 

to publish as a final rule. A conforming 

change is being made to the revised 10 

CFR 40.13(c)(5)(v) provision, so that it 

will contain the proper cross-reference 

to § 40.56. These amendments are 

administrative in that they make no 

substantive changes to requirements, 

and the NRC accordingly finds that 

notice and opportunity for public 

comment on this corrective action is 

unnecessary.

Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Rolls-Royce plc (RR) RB211-Trent 800 

Series Turbofan Engines. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

originated 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 fuel leaks from the engine 

due to damage to sections of the fan case 

low-pressure (LP) fuel tubes. We are 

issuing this AD to prevent engine fuel 

leaks, which could result in risk to the 

airplane. 

DATES: This AD becomes effective 

January 24, 2012. The Director of the 

Federal Register approved the 


pmangrum on DSK3VPTVN1PROD with RULES
78806 Federal Register / Vol. 76, No. 244 / Tuesday, December 20, 2011 / Rules and Regulations 

incorporation by reference of certain 

publications listed in this AD as of

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on August 22, 2011 (76 FR 

52288). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Fuel leaks from the engine have occurred 

in-service due to damage to sections of the 

fan case Low Pressure (LP) fuel tubes which 

run between the Low Pressure and the High 

Pressure (HP) fuel pumps. This damage has 

been caused by frettage between the securing 

clips and the tube outer surface, which has 

caused localised thinning of the tube wall 

thickness. The thinning of the tube wall 

causes the tube to fracture and fuel loss to 

occur. 

The corrective action includes 

inspection of the tubes and replacement 

of the associated clips. The fretting and 

thinning of the fuel tubes is caused by 

relative movement between the tubes 

and the clips. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Correct Title in Rolls-Royce 

Service Bulletin 

A commenter, Air New Zealand, 

requested that we change the service 

bulletin reference from ‘‘RB.211–73– 

D685’’ to ‘‘RB.211–73–AD685.’’ 

We agree. The changed the AD to 

correct the service bulletin reference. 

Request To Change Service Bulletin 

Revision Number 

Three commenters, American Airlines 

(American), Delta Airlines (Delta), and 

the Boeing Company (Boeing), suggested 

that we change compliance from 

Revision 5 to Revision 6 of the RollsRoyce Service Bulletin. 

We agree. We changed the AD to use 

RR SB RB.211–73–AD685, Revision 6, 

dated February 21, 2011, which is the 

latest version of the service bulletin. 

Request To Allow Compliance to 

Earlier Revisions of the Service Bulletin 

One commenter, Delta, asked that 

engines previously inspected per 

Revision 3 of SB RB.211–73–AD685, 

dated August 18, 2009; or Revision 4 of 

SB RB.211–73–AD685, dated January 

20, 2010 or Revision 5 of SB RB.211– 

73–AD685, dated August 18, 2010; to 

have met the initial inspection 

requirements of the AD. 

We agree. We added a new paragraph 

to the AD called ‘‘Previous Inspection 

Credit’’ which provides credit for 

performing the initial inspection 

according to the requirements of 

Revisions 3, 4, or 5 of the SB. 

Request To Revise Cost of Compliance 

A commenter, American Airlines, 

requested that the cost estimate per 

engine be increased to $905. American 

noted that the AD creates repetitive not 

one-time expenses due to the need for 

repetitive inspections. American also 

asserted that the estimate in the NPRM 

(76 FR 52288, August 22, 2011) of labor 

hours to comply with the AD was not 

accurate. American suggested 8 labor 

hours per inspection is a realistic figure. 

We agree in part. While the AD does 

require repetitive inspections, we do not 

agree with including repetitive expenses 

for inspections in our cost estimate. We 

only include the cost of one inspection 

cycle, even if the AD requires repetitive 

inspections, in our cost estimates. We 

agree our labor estimate should be 

increased. We accept that 8 labor hours 

is a realistic estimate of labor hours and 

allows us to make a more accurate 

assessment of labor cost. We changed 

the estimate of work hours in the AD 

from 3 to 8. We also corrected the cost 

of the parts required from $225 in the 

NPRM to $884. We revised the total cost 

to comply with the AD from $52,800 to 

$172,040. 

Request To Revise Initial Inspection 

Paragraph 

A commenter, Boeing, requested that 

the Initial Inspection paragraph be 

revised by including the following: 

‘‘Inspect the Fuel Oil Heat Exchanged 

(FOHE) mounting hardware for signs of 

damage. Use paragraph 3.A.(4) of the 

Service Bulletin RB.211–73–AD685, 

Revision 6, dated February 21, 2011.’’ 

Boeing noted that damage or wear to 

FOHE mounts may contribute to low 

pressure (LP) fuel tube cracking. Delta 

Airlines commented further that EASA 

AD 2010–0188 requires this FOHE 

mount inspection because it requires 

accomplishment of the entire service 

bulletin when doing the inspection. For 

clarity, Delta requested that the final 

rule include a comment that the 

inspection requirements do not mandate 

the FOHE mount inspections. 

We do not agree. The requirement of 

this AD to inspect the fuel tubes is 

sufficient to ensure safe operation. The 

repetitive inspection intervals for fuel 

tubes required by this AD consider 

observed FOHE mount wear. This AD 

does not require inspection of the FOHE 

mounts. We did not change the AD 

based on this comment. 

Request To Add Requirement To 

Remove Damaged Fuel Tubes 

Two commenters, Boeing and Delta, 

requested clarification regarding when 

to replace fuel tubes. Boeing requested 

that under ‘‘Actions and Compliance’’ 

the following requirement be included: 

‘‘Removal and replacement of damaged 

fuel tubes (P/N FK23986) in accordance 

with paragraph 3.A.(5) of the Service 

Bulletin RB.211–73–AD685, Revision 6, 

dated February 21, 2011.’’ Boeing 

indicated that rejected fuel tubes need 

to be replaced to avoid fuel leaks. Delta 

indicated that the On-wing Inspection 

and In-shop Inspection paragraphs do 

not include information about replacing 

tubes when needed as the result of 

inspections. Delta also noted that the 

Repetitive Inspection paragraph does 

discuss replacement of these parts when 

needed. 

We agree in part. Although parts that 

fail inspection may not be returned to 

service, we agree that clarifying when 

fuel tubes are replaced would help. We 

revised the On-wing Inspection and Inshop Inspection paragraphs to indicate 

that the tubes should be replaced if they 

fail inspection. 

Request To Clarify Initial Inspection 

Requirement 

One commenter, Delta, noted that 

under the Initial Inspection paragraph, 

one of the options for complying with 

the AD is to do the initial inspection 

before 3,000 hours since last inspection. 

Delta requested that we clarify the 

meaning of ‘‘last inspection.’’ 

We agree. We added a definition 

paragraph to indicate that our reference 

to 3,000 hours since last inspection 

refers to the inspection of the fan case 

LP fuel tubes for frettage between the 

securing clips and the tube outer surface 

part numbers FK22617, FK19213, and 

FK23986. 


pmangrum on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 76, No. 244 / Tuesday, December 20, 2011 / Rules and Regulations 78807 

Request To Clarify Handling of Clips 

for Fuel Tubes 

One commenter, Delta, asked that the 

final rule clarify how to handle the clips 

that hold the fuel tubes in place. Delta 

noted that paragraphs 3.A.(2) and 

3.A.(3) (on-wing) and 3.B.(2) and 3.B.(3) 

of RR SB RB.211–73–AD685, which are 

referenced in the NPRM (76 FR 52288), 

do not include inspection criteria for the 

clips. Delta requested that we either 

require inspection or replacement of the 

clips with a new or serviceable part per 

the note in Paragraph 3.A. of the RR SB 

RB.211–73–AD685, which says that 

‘‘clips should be removed and replaced 

one at a time to prevent pre-loading of 

the clip position.’’ 

We agree. The fretting and thinning of 

the fuel tubes is caused by relative 

movement between the tubes and the 

clips. Worn or fretted clips cause 

increased relative movement between 

the tubes and the clips and thus more 

tube wear and fretting. Clip wear is not 

repairable and so the clips cannot be 

reused. We, therefore, revised the AD by 

changing the On-wing Inspection and 

In-shop Inspection paragraphs to 

indicate that the clips must be replaced 

during the initial inspection and during 

every repeat inspection. 

Request To Clarify Repeat Inspections 

Paragraph 

One commenter, Delta, requested 

clarification of the Repeat Inspections 

paragraph. Delta noted that this 

paragraph might be misinterpreted to 

mean inspection and tube replacement 

should be accomplished per paragraphs 

3.A.(2), 3.A.(3), 3.B.(2), and 3.B.(3) of RR 

SB RB.211–73–AD685. Since these 

paragraphs only apply to replacement of 

the tubes, Delta believes the language 

should be clarified. 

We agree. We revised the Repeat 

Inspections paragraph to clarify that 

paragraphs 3.A.(1) through 3.A.(3) (Onwing) or 3.B.(1) through 3.B.(3) (Inshop) of RR SB RB.211–78–AD685 

apply to the inspection. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator nor increase the scope of 

the AD. 

Costs of Compliance 

We estimate that this AD affects about 

110 products of U.S. registry. We also 

estimate that it will take about 8 workhours per product to comply with this 

AD. The average labor rate is $85 per 

work-hour. Required parts cost about 

$884 per product. Based on these 

figures, we estimate the cost of the AD 

on U.S. operators to be $172,040. 

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 

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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at 

http://www.regulations.gov; or in person 

at the Docket Operations office between 

9 a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (phone: 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

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 airworthiness 

directive (AD): 

2011–26–08 Rolls-Royce plc: Amendment 

39–16898; Docket No. FAA–2011–0836; 

Directorate Identifier 2010–NE–38–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective January 24, 2012. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Rolls-Royce plc (RR) 

RB211–Trent 875–17, 877–17, 884–17, 884B– 

17, 892–17, 892B–17, and 895–17 turbofan 

engines. These engines are installed on, but 

not limited to, Boeing 777 series airplanes. 

(d) Reason 

This AD was prompted by fuel leaks from 

the engine that occurred in-service due to 

damage to sections of the fan case lowpressure (LP) fuel tubes, which run between 

the LP and the high-pressure (HP) fuel 

pumps. This damage was caused by frettage 

between the securing clips and the tube outer 

surface, which caused localized thinning of 

the tube wall thickness. The thinning of the 

tube wall causes the tube to fracture and leak 

fuel. We are issuing this AD to prevent 

engine fuel leaks, which could result in risk 

to the airplane. 

(e) Actions and Compliance 

Unless already done, do the following 

actions. 

(f) Initial Inspection and Clip replacement 

Within 2,000 hours in service after the 

effective date of this AD, or before

Airworthiness Directives; Teledyne 

Continental Motors (TCM) and RollsRoyce Motors Ltd. (R–RM) Series 

Reciprocating Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

certain TCM and R–RM series 

reciprocating engines. That AD 

currently requires replacement of 

certain magnetos if they fall within the 

specified serial number (S/N) range, 

inspection of the removed magneto to 

verify that the stop pin is still in place, 

and, if the stop pin is not in place, 

inspection of the engine gear train, 

crankcase, and accessory case. This new 

AD corrects the range of S/Ns affected, 

requires the same replacement and 

inspections, and adds R–RM C–125, C– 

145, O–300, IO–360, TSIO–360, and 

LTSIO–520–AE series reciprocating 

engines to the applicability. This AD 

was prompted by our awareness of an 

error in the previous AD applicability in 

the range of magneto S/Ns affected and 

of the need to include certain engines 

made by R–RM, under license of TCM. 

We are issuing this AD to prevent 

engine failure and loss of control of the 

airplane due to migration of the 

magneto impulse coupling stop pin out 

of the magneto frame and into the gear 

train of the engine. 

DATES: This AD is effective January 24, 

2012.
