Airworthiness Directives; Rolls-Royce 

plc (RR) Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to all RR model RB211– 

524G2–T–19, –524G3–T–19, –524H–T– 

36, and –524H2–T–19; and RB211– 

Trent 553–61, 553A2–61, 556–61, 

556A2–61, 556B–61, 556B2–61, 560–61, 

560A2–61; RB211–Trent 768–60, 772– 

60, 772B–60; and RB211–Trent 875–17, 

877–17, 884–17, 884B–17, 892–17, 

892B–17, and 895–17 turbofan engines 

that have a high-pressure (HP) 

compressor stage 1 to 4 rotor disc with 

a part number (P/N) listed in Table 1 of 

this proposed AD. The existing AD 

currently requires repetitive inspections 

of the axial dovetail slots, and follow-on 

corrective action depending on findings. 

Since we issued that AD, we determined 

that the definition of shop visit is too 

restrictive in the existing AD. This 

proposed AD would continue to require 

those repetitive inspections and followon corrective actions, and it would 

change the definition of a shop visit to 

be less restrictive. We are proposing this 

AD to detect cracks in the HP 

compressor stage 1 and 2 disc posts, 

which could result in failure of the disc 

post and HP compressor blades, release 

of uncontained engine debris, and 

damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by December 19, 

2011. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

On April 12, 2011, we issued AD 

2011–09–07, Amendment 39–16669 (76 

FR 24793, May 3, 2011), for all RR 

model RB211–524G2–T–19, –524G3–T– 

19, –524H–T–36, and –524H2–T–19; 

and RB211 Trent 553–61, 553A2–61, 

556–61, 556A2–61, 556B–61, 556B2–61, 

560–61, 560A2–61; RB211 Trent 768– 

60, 772–60, 772B–60; and RB211 Trent 

875–17, 877–17, 884–17, 884B–17, 892– 

17, 892B–17, and 895–17 turbofan 

engines. That AD requires initial and 

repetitive fluorescent penetrant 

inspections of the HP compressor stage 

1 to 4 rotor discs at the first shop visit 

after accumulating 1,000 cycles-sincenew on the stage 1 to 4 rotor discs or 

at the next shop visit after the effective 

date of that AD, which ever occurs later. 

That AD also requires repetitive 

inspections at every shop visit. That AD 

resulted from findings of anomalies at 

the corners of the disc posts during 

manufacture of stage 1 and stage 2 discs 

with axial dovetails slots. We issued 

that AD to detect cracks in the HP 

compressor stage 1 and stage 2 disc 

posts, which could result in failure of 

the disc post and release of HP 

compressor blades, release of 

uncontained engine debris, and damage 

to the airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 2011–09–07, 

Amendment 39–16669 (76 FR 24793, 

May 3, 2011), we found that the 

definition of ‘‘shop visit’’ in the AD is 

too restrictive, in that it would require 

operators to inspect more often than 

required to ensure safety. We also found 

that Alert Service Bulletin (ASB) No. 

RB.211–72–AF964, Revision 2, dated 

June 8, 2011, also may be appropriate to 


pmangrum on DSK29S0YB1PROD with PROPOSALS
Federal Register / Vol. 76, No. 203 / Thursday, October 20, 2011 / Proposed Rules 65137 

the corrective action in that AD, as is 

ASB No. RB.211–72–AF964, Revision 1, 

dated June 6, 2008 which is referenced 

in AD 2011–09–07. 

Relevant Service Information 

We reviewed RR ASB No. RB.211–72– 

AF964, Revision 1, dated June 6, 2008, 

and Revision 2, dated June 8, 2011. The 

ASB describes procedures for cleaning 

and inspecting the axial dovetail slots. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the definition of shop 

visit was too restrictive, and that the 

unsafe condition described previously is 

likely to exist or develop in other 

products of these same type designs. 

Proposed AD Requirements 

This proposed AD would change the 

definition of a shop visit in AD 2011– 

09–07 to ‘‘whenever all compressor 

blades are removed from the HP 

compressor drum.’’ This proposed AD 

would also allow using ASB No. 

RB.211–72–AF964, Revision 1, dated 

June 6, 2008, or ASB No. RB.211–72– 

AF964, Revision 2, dated June 8, 2011, 

to perform the inspection. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 371 products of U.S. 

registry. We also estimate that it would 

take about 20 work-hours per product to 

comply with this AD. The average labor 

rate is $85 per work-hour. No parts 

would be required per product. Based 

on these figures, we estimate the cost of 

the AD on U.S. operators to be $630,700. 

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 have 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 that the 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.

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) 

2011–09–07, Amendment 39–166679 

(76 FR 24793, May 3, 2011), and adding 

the following new AD: 

Rolls-Royce plc: Docket No. FAA–2010– 

0562; Directorate Identifier 2009–NE– 

29–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

AD action by December 19, 2011. 

(b) Affected ADs 

This AD supersedes AD 2011–09–07, 

Amendment 39–16669 (76 FR 24793, May 3, 

2011). 

(c) Applicability 

This AD applies to Rolls-Royce plc (RR) 

model RB211–524G2–T–19, –524G3–T–19, 

–524H–T–36, and –524H2–T–19; and RB211–

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

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

engines that have a high-pressure (HP) 

compressor stage 1 to 4 rotor disc with a part

(d) Unsafe Condition 

This AD was prompted by our 

determination that the definition of ‘‘shop 

visit’’ in the existing AD is too restrictive, in 

that it would require operators to inspect 

more often than required to ensure safety. We 

are issuing this AD to detect cracks in the HP 

compressor stage 1 and 2 disc posts, which 

could result in failure of the disc post and 

HP compressor blades, release of 

uncontained engine debris, and damage to 

the airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done.

On page 62690, column 2, in the 

preamble, under the paragraph heading 

‘‘Explanation of Provisions’’, first 

paragraph of the column, line 17, the
