14 CFR Part 39

Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

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 required 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 AD requires 

removal of either the affected sealing 

sleeve only or both the affected sealing 

sleeve and the oil feed tube. This AD 

was prompted by fractures of the 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, uncontained 

engine failure, and damage to the 

airplane. 

DATES: This AD is effective April 19, 

2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 19, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2015–04–03, 

Amendment 39–18105 (80 FR 9380, 

February 23, 2015), (‘‘AD 2015–04–03’’). 

AD 2015–04–03 applied to the specified 

products. The NPRM published in the 

Federal Register on November 10, 2015 

(80 FR 69625). The NPRM proposed to 

require removal of either the affected 

sealing sleeve only or both the affected 

sealing sleeve and the oil feed tube. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. The 

commenter supports the NPRM (80 FR 

69625, November 10, 2015). 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed. 

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, 

including the Supplement, Revision 1, 

dated July 29, 2015. The Alert NMSB 

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

August 10, 2015, provides guidance on 

identification and replacement of the 

sealing sleeve, part number (P/N) 

FW15003. The SB No. RB.211–72–H754, 

including the Supplement, Revision 1, 

dated July 29, 2015, 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 AD. 

Costs of Compliance 

We estimate that this AD affects 58 

engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 1.2 hours per engine to 

comply with this AD. The average labor 

rate is $85 per hour. Required parts cost 

about $5,850 per engine. Based on these 

figures, we estimate the cost of this 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 


asabaliauskas on DSK3SPTVN1PROD with RULES
13714 Federal Register / Vol. 81, No. 50 / Tuesday, March 15, 2016 / Rules and Regulations 

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 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.

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

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:

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

uncontained engine failure, and damage to 

the airplane.

sufficiently identified, then within 1,600 

flight cycles or 24 months after the effective 

date of this AD, whichever occurs first: 

(i) Remove the affected sealing sleeve, 

P/N FW15003, and replace it with a part
