AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for all RR RB211-Trent 553–61, 553A2– 

61, 556–61, 556A2–61, 556B–61, 

556B2–61, 560–61, 560A2–61, 768–60, 

772–60, 772B–60, 875–17, 877–17, 884– 

17, 884B–17, 892–17, 892B–17, and 

895–17 turbofan engines. That NPRM 

proposed to supersede an existing AD 

that requires inspecting the 

intermediate-pressure (IP) compressor 

rotor shaft rear balance land for cracks, 

which could lead to engine failure. This 

action revises that NPRM by changing 

the optional terminating action for 

RB211-Trent 700 and RB211-Trent 800 

engines to mandatory terminating 

action. Since these actions impose an 

additional burden over that proposed in 

the NPRM, we are reopening the 

comment period to allow the public the 

chance to comment on these proposed 

changes. 

DATES: We must receive comments on 

this supplemental NPRM by March 20, 

2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

We issued an NPRM to amend 14 CFR 

part 39 to include an AD that would 

apply to RR RB211-Trent 553–61, 

553A2–61, 556–61, 556A2–61, 556B–61, 

556B2–61, 560–61, 560A2–61, 768–60, 

772–60, 772B–60, 875–17, 877–17, 884– 

17, 884B–17, 892–17, 892B–17, and 

895–17 turbofan engines. That NPRM 

published in the Federal Register on 

October 18, 2011 (76 FR 64283). That 

NPRM proposed to require for certain 

RB211-Trent 700 and RB211-Trent 800 

engines, on-wing initial and repetitive 

borescope inspections and when in the 

shop, repetitive eddy current 

inspections (ECIs) for cracks on the rear 

balance land; and continued for RB211- 

Trent 500 engines, initial and repetitive 

in-shop visual inspections or ECIs for 

cracks on the rear balance land. That 

NPRM also proposed certain optional 

terminating actions. 

Actions Since Previous NPRM Was 

Issued 

Since we issued that NPRM, RR has 

ceased efforts to develop an on-wing 

ECI. Therefore the optional terminating 

action for RB211-Trent 700 and RB211- 

Trent 800 engines only, should be made 

mandatory. EASA has also superseded 

EASA AD 2010–0266R1, dated January 

6, 2011, with EASA Airworthiness 

Directive 2011–0221, dated November 

14, 2011 to accomplish the same 

corrective actions as proposed herein. 

Comments 

We gave the public the opportunity to 

comment on the previous NPRM. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Request 

US Airways requested that we allow 

borescope inspection using RR Alert 

Service Bulletin (ASB) No. RB.211–72– 

AG270 when at shop visit, if the 

exposure of the IP compressor is not 

visible for ECI. The commenter stated 

that airlines will incur more 

maintenance costs if not allowed to do 

borescope inspections under this 

circumstance. 

We do not agree. The visual/ECI is not 

required unless the rear face of the IP 

compressor is exposed. Our Definition 

paragraph defined a shop visit as the 

introduction of an engine into a shop, 

and disassembly sufficient to expose the 

IP compressor module rear face. We did 

not change the NPRM. 

Request 

The Boeing Airplane Company, RollsRoyce plc, and American Airlines 

requested that we correct two service 

bulletin reference errors and two 

paragraph reference errors in the 

compliance section. We agree. We 

revised this NPRM by changing the 

Service Bulletin (SB) and paragraph 

reference errors, specifically changing 

‘‘RR SB No. RB.211–72–G402, Revision 

2, dated July 7, 2011’’ to ‘‘RR ASB No. 

RB.211–72–AG402, Revision 2, dated 

July 7, 2011’’, changing ‘‘RR SB No. 

RB.211–72–G401, Revision 2, dated July 

5, 2011’’ to ‘‘RR ASB No. RB.211–72– 

AG401, Revision 2, dated July 5, 2011’’, 

changing the reference in paragraph 

(k)(2)(i) from ‘‘(h)’’ to ‘‘(g)(1)(i)’’, and by 

changing paragraph ‘‘(f)(3)’’ to 

paragraph ‘‘(g)’’. 

Request 

Rolls-Royce plc requested that, when 

referencing the RB211-Trent 800 service 

information, we make the inspection 

requirements consistent with the 

RB211-Trent 700 inspection 

requirements, as they are the same 

except for the compliance interval. 

We agree. We changed paragraph 

(g)(1)(i) in this NPRM to state to use RR 

ASB No. RB.211–72–AG264, Revision 5, 

dated March 21, 2011, sections 

3.A.(2)(b) through 3.A.(2)(c) and 

3.A.(3)(a) through 3.A.(3)(c), or 3.B.(2)(a) 

through 3.B.(2)(c) and 3.B.(4)(a) through 

3.B.(4)(c), to do the inspection. 

Request 

Rolls-Royce plc requested that we 

reference EASA AD 2011–0221, dated 

November 14, 2011, in the NPRM since 

it supersedes EASA AD 2010–0266R1, 

dated January 6, 2011. 

We agree and changed the EASA AD 

reference. 

Request 

Rolls-Royce plc requested that we 

change the compliance time from ‘‘next 

shop visit’’, to ‘‘next shop visit or within 

90 months after the effective date of the 

AD’’ to be consistent with EASA’s AD. 

We do not agree. The fretting caused 

by movement between the balance 

weights and the IPC rear face is related 

to engine run time, not calendar time. 

Shop visits are also related to average 

run time. We did not change the NPRM. 

FAA’s Determination 

We are proposing this supplemental 

NPRM because we evaluated all the 

relevant information and determined 

the unsafe condition described 

previously is likely to exist or develop 

in other products of these same type 

designs. Certain changes described 

above expand the scope of the original 

NPRM. As a result, we have determined 

to reopen the comment period to 

provide additional opportunity for the 

public to comment on this supplemental 

NPRM. 

Proposed Requirements of the 

Supplemental NPRM 

This supplemental NPRM would 

require: 

• For the RB211-Trent 700 and 

RB211-Trent 800 engines, on wing 

initial and repetitive borescope 

inspections and when in the shop, 

repetitive ECIs and visual inspections 

for cracks on the rear balance land; and 

• For the RB211-Trent 500 engines, 

initial and repetitive in-shop visual 

inspections or ECIs for cracks on the 

rear balance land. 

• For the RB211-Trent 700 and 

RB211-Trent 800 engines, adding a 

mandatory terminating action to the 

repetitive inspection requirements. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 136 engines installed 

on airplanes of U.S. registry. We also 

estimate that it would take about 3.5 

work-hours per engine to perform the 

proposed on-wing/in-shop visual 

inspections, about 2.5 work-hours per 

engine to perform the proposed in-shop 

ECIs, and about 8 work-hours to 

rebalance the IP compressor. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

total cost of the proposed AD to U.S. 

operators to be $470,696. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 


wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
2934 Federal Register / Vol. 77, No. 13 / Friday, January 20, 2012 / Proposed Rules 

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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

(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), 

(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. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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) 

2008–18–08, Amendment 39–15665 (73 

FR 52201, September 9, 2008), and 

adding the following new AD: 

Rolls-Royce plc: Docket No. FAA–2007– 

28059; Directorate Identifier 2007–NE– 

13–AD. 

(a) Comments Due Date 

We must receive comments by March 20, 

2012. 

(b) Affected ADs 

This AD supersedes AD 2008–18–08, 

Amendment 39–15665, (73 FR 52201, 

September 9, 2008). 

(c) Applicability 

This AD applies to Rolls-Royce plc (RR) 

RB211-Trent 553–61, 553A2–61, 556–61, 

556A2–61, 556B–61, 556B2–61, 560–61, 

560A2–61, 768–60, 772–60, 772B–60, 875– 

17, 877–17, 884–17, 884B–17, 892–17, 892B– 

17, and 895–17 turbofan engines. 

(d) Unsafe Condition 

We are superseding AD 2008–18–08 

because additional cracks on RB211-Trent 

700 and RB211-Trent 800 intermediatepressure (IP) compressor rotor shafts have 

been found since that AD was issued. This 

cracking could lead to IP compressor rotor 

shaft failure, uncontained engine failure, and 

damage to the airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(f) RB211-Trent 700 Series Engines—Rear 

Balance Land Inspections 

(1) On-Wing Inspections 

(i) Within 625 cycles-in-service (CIS) after 

the effective date of this AD, borescope 

inspect the IP compressor rotor shaft rear 

balance land. Use RR Alert Service Bulletin 

(ASB) No. RB.211–72–AG270, Revision 4, 

dated March 21, 2011, sections 3.A.(2)(a) 

through 3.A.(2)(c) and 3.A.(3)(a) through 

3.A.(3)(c), or 3.B.(2)(a) through 3.B.(2)(c) and 

3.B.(4)(a) through 3.B.(4)(c), to do the 

inspection. 

(ii) Thereafter, repeat the inspection within 

every 625 cycles-since-last inspection (CSLI). 

You may count CSLI from the last borescope 

inspection or the last eddy current 

inspection, whichever has occurred last. 

(2) In-Shop Inspections 

At each shop visit, eddy current inspect 

(ECI) and visually inspect the IP compressor 

rotor shaft rear balance land, and visually 

inspect the balance weights. Use RR ASB No. 

RB.211–72–AG085, Revision 2, dated July 7, 

2011, sections 3.A. through 3.D.(3)(b)(v), 

except paragraphs 3.D.(3)(a)(ii) and 

3.D.(3)(b)(iii) to do the inspections. 

(g) RB211-Trent 800 Series Engines—Rear 

Balance Land Inspections 

(1) On-Wing Inspections 

(i) Within 475 CIS after the effective date 

of this AD, borescope inspect the IP 

compressor rotor shaft rear balance land. Use 

RR ASB No. RB.211–72–AG264, Revision 5, 

dated March 21, 2011, sections 3.A.(2)(b) 

through 3.A.(2)(c) and 3.A.(3)(a) through 

3.A.(3)(c), or 3.B.(2)(a) through 3.B.(2)(c) and 

3.B.(4)(a) through 3.B.(4)(c), to do the 

inspection. 

(ii) Thereafter, repeat the inspection within 

every 475 CSLI. You may count CSLI from 

the last borescope inspection or the last eddy 

current inspection, whichever has occurred 

last. 

(2) In-Shop Inspections 

At each shop visit, ECI and visually inspect 

the IP compressor rotor rear shaft balance 

land, and visually inspect the balance 

weights. Use RR ASB No. RB.211–72–AG085, 

Revision 2, dated July 7, 2011, sections 3.A. 

through 3.D.(3)(b)(v), except paragraphs 

3.D.(3)(a)(ii) and 3.D.(3)(b)(iii), to do the 

inspections. 

(h) RB211-Trent 500 Series Engines—InShop Rear Balance Land Inspections 

At each shop visit, ECI the IP compressor 

rotor shaft and visually inspect the balance 

weights. Use RR ASB No. RB.211–72–AF260, 

Revision 5, dated July 7, 2011 sections 3.A. 

through 3.B.(3)(a)(iii) to do the visual 

inspection, or RR Service Bulletin (SB) No. 

RB.211–72–G448, Revision 3, dated July 7, 

2011 section 3.D.(1) through 3.D.(14) to do 

the ECI. 

(i) Definition 

For the purposes of this AD, a shop visit 

is defined as introduction of an engine into 

a shop, and disassembly sufficient to expose 

the IP compressor module rear face. 

(j) Mandatory Terminating Action for 

RB211-Trent 700 and RB211-Trent 800 

Engines 

(1) As mandatory terminating action to the 

in-shop repetitive inspections in paragraph 

(f)(2) of this AD, at the next shop visit in 

which any level of inspection or strip is 

scheduled to be carried out on the IPC, 

modify RB211-Trent 700 engines by 

removing the existing IPC balance weights, 

and then rebalancing the IPC as specified in 

paragraphs 3.B.(2) through 3.B.(6)(e) and 

3.B.(6)(g) of RR ASB No. RB.211-–72–AG402, 

Revision 2, dated July 7, 2011. 

(2) As mandatory terminating action to the 

in-shop repetitive inspections in paragraph 

(g)(2) of this AD, at the next shop visit in 

which any level of inspection or strip is
