AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2015–04– 

03 that applies to certain Rolls-Royce 

plc (RR) RB211 Trent 768–60, 772–60, 

and 772B–60 turbofan engines. AD 

2015–04–03 requires inspection of the 

sealing sleeve on the high-pressure/

intermediate-pressure (HP/IP) turbine 

support internal oil feed tube and 

removal of those sealing sleeves affected 

by AD 2015–04–03. This proposed AD 

would require removal of either the 

affected sealing sleeve only or both the 

affected sealing sleeve and the oil feed 

tube. We are proposing this AD to 

prevent failure of the HP/IP turbine 

support internal oil feed tube, which 

could lead to uncontained engine failure 

and damage to the airplane.

Discussion 

On February 11, 2015, we issued AD 

2015–04–03, Amendment 39–18105 (80 


rmajette on DSK2TPTVN1PROD with PROPOSALS
69626 Federal Register / Vol. 80, No. 217 / Tuesday, November 10, 2015 / Proposed Rules 

FR 9380, February 23, 2015), for certain 

RR RB211 Trent 768–60, 772–60, and 

772B–60 turbofan engines. AD 2015– 

04–03 requires inspection of the sealing 

sleeve on the HP/IP turbine support 

internal oil feed tube and removal of 

those sealing sleeves affected by AD 

2015–04–03. AD 2015–04–03 resulted 

from fractures of the HP/IP turbine 

support internal oil feed tube. We 

issued AD 2015–04–03 to prevent 

failure of the HP/IP turbine support 

internal oil feed tube, which could 

result in uncontained engine failure and 

damage to the airplane. 

Actions Since AD 2015–04–03 Was 

Issued 

Since we issued AD 2015–04–03, 

Amendment 39–18105 (80 FR 9380, 

February 23, 2015), we received a report 

of high oil consumption on an engine 

that did not have an affected sealing 

sleeve. The manufacturer’s investigation 

revealed that certain oil feed tube 

threaded end adapters were 

manufactured with the outer diameter 

larger than the drawing maximum, 

which can cause binding of the sliding 

joint and ultimately lead to low-cycle 

fatigue failure of the HP/IP turbine 

support internal oil feed tube. Also 

since we issued AD 2015–04–03, the 

European Aviation Safety Agency has 

issued AD 2015–0105R1, dated August 

18, 2015, which requires inspection of 

the affected sealing sleeve and removal 

of the affected sealing sleeve or removal 

of both the affected sealing sleeve and 

oil feed tube. 

Related Service Information Under 1 

CFR Part 51 

RR has issued RR Alert NonModification Service Bulletin (NMSB) 

No. RB.211–72–AJ035, Revision 2, dated 

August 10, 2015 and RR Service 

Bulletin (SB) No. RB.211–72–H754, 

dated October 1, 2014. The Alert NMSB 

No. RB.211–72–AJ035, Revision 2, dated 

August 10, 2015, provides guidance on 

identification of the sealing sleeve, part 

number (P/N) FW15003, and 

replacement of the non-conforming 

sealing sleeve, P/N FW15003, with a 

conforming sealing sleeve, P/N 

FW15003. The SB No. RB.211–72–H754, 

dated October 1, 2014, provides 

information on the replacement of the 

sealing sleeve, P/N FW15003, and oil 

feed tube, P/N FW14193, with a sealing 

sleeve, P/N KH28323 and oil feed tube, 

P/N KH28324. This service information 

is reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section of this NPRM. 

FAA’s Determination 

We are proposing 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. 

Proposed AD Requirements 

This proposed AD would require 

removal of the affected sealing sleeve 

only or both the affected sealing sleeve 

and the oil feed tube. Both corrective 

actions eliminate the unsafe condition 

caused by affected sealing sleeves and/ 

or affected oil feed tube threaded end 

adapters. 

Costs of Compliance 

We estimate that this proposed AD 

affects 58 engines installed on airplanes 

of U.S. registry. We also estimate that it 

would take about 1.2 hours per engine 

to comply with this proposed AD. The 

average labor rate is $85 per hour. 

Required parts cost approximately 

$5,850 per engine. Based on these 

figures, we estimate the cost of this 

proposed AD on U.S. operators to be 

$345,216. 

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 to the extent that it justifies 

making a regulatory distinction, 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) 

2015–04–03, Amendment 39–18105 (80 

FR 9380, February 23, 2015) (‘‘AD 2015– 

04–03’’), and adding the following new 

AD: 

Rolls-Royce plc: Docket No. FAA–2014– 

0561; Directorate Identifier 2014–NE– 

12–AD. 

(a) Comments Due Date 

We must receive comments by January 11, 

2016. 

(b) Affected ADs 

This AD supersedes AD 2015–04–03. 

(c) Applicability 

This AD applies to Rolls-Royce plc (RR) 

RB211 Trent 768–60, 772–60, and 772B–60 

turbofan engines, all serial numbers, except 

those engines: 

(1) That have had Modification 72–H754 

applied in production, or 

(2) that have been modified in accordance 

with RR Service Bulletin (SB) No. RB.211– 

72–H754, dated October 1, 2014, or 

(3) with sealing sleeve, part number (P/N) 

FW15003, with markings 102013, 112013, or 

102013L. 

(d) Unsafe Condition 

This AD was prompted by fractures of the 

high-pressure/intermediate pressure (HP/IP) 

turbine support internal oil feed tube. We are 

issuing this AD to prevent failure of the HP/ 

IP turbine support internal oil feed tube, 

which could result in uncontained engine 

failure and damage to the airplane.

Pennsylvania; Allegheny County’s 

Adoption of Control Techniques 

Guidelines for Four Industry 

Categories for Control of Volatile 

Organic Compound Emissions 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to convert 

the conditional approval of revisions to 

the Pennsylvania State Implementation 

Plan (SIP) submitted by the 

Commonwealth of Pennsylvania on 

behalf of the Allegheny County Health 

Department (ACHD) to a full approval. 

The SIP revision included amendments 

to the ACHD Rules and Regulations, 

Article XXI, Air Pollution Control, and 

meets the requirement to adopt 

Reasonably Available Control 

Technology (RACT) for sources covered 

by EPA’s Control Techniques 

Guidelines (CTG) standards for the 

following categories: Miscellaneous 

metal and/or plastic parts surface 

coating processes, automobile and lightduty truck assembly coatings, 

miscellaneous industrial adhesives, and 

fiberglass boat manufacturing materials. 

Upon review of the submittal, EPA 

found that the average monomer volatile 

organic compound (VOC) content limits 

were referenced but not included in the 

regulation for fiberglass boat 

manufacturing materials. ACHD has 

revised the regulation and submitted the 

table of VOC content limits for fiberglass 

boat manufacturing materials to EPA in 

order to address specific RACT 

requirements for Allegheny County. 

EPA is, therefore, proposing to convert 

the conditional approval to a full 

approval of the revisions to the 

Pennsylvania SIP in accordance with 

the requirements of the Clean Air Act 

(CAA).
