regulation or whether these burdens 

must be addressed by legislative action. 

For purposes of this review, the 

Agencies have grouped our combined 

regulations into 12 categories: 

Applications and Reporting; Banking 

Operations; Capital; Community 

Reinvestment Act; Consumer Protection; 

Directors, Officers and Employees; 

International Operations; Money 

Laundering; Powers and Activities; 

Rules of Procedure; Safety and 

Soundness; and Securities. On June 4, 

2014, we published a Federal Register 

notice asking for public comment on 

three of these categories—Applications 

and Reporting, Powers and Activities, 

and International Operations 

regulations.2 We also published a chart 

listing all of the regulations included in 

the EGRPRA review. Over the next 

eighteen months, we will publish 

additional notices, seeking comment on 

the remaining categories.

Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

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 Rolls-Royce plc (RR) RB211 Trent 

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

17, 892B–17, and 895–17 turbofan 

engines. The NPRM proposed to require 

modification of the engine by removing 

any electronic engine control (EEC) that 

incorporates EEC software standard 

prior to version B7.2 and installing an 

EEC eligible for installation. The NPRM 

was prompted by failure of the 

intermediate pressure (IP) turbine disk 

drive arm and subsequent overspeed 

and burst of the IP turbine disk on an 

RR RB211 Trent turbofan engine. This 

action revises the NPRM by clarifying 

the costs of compliance, by clarifying 

that correction of the unsafe condition 

can be achieved either by installing 

upgraded software in the EEC or by 

installing an EEC with upgraded 

software incorporated, and by clarifying 

the installation prohibition statement. 

We are proposing this supplemental 

NPRM (SNPRM) to prevent overspeed of 

the IP turbine disk, resulting in failure 

of the turbine blades or the IP turbine 

disk and subsequent uncontained 

release of the disk and/or turbine 

blades, which could lead to damage to 

the engine and damage to the airplane.

Discussion 

We issued an NPRM to amend 14 CFR 

part 39 by adding an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on July 11, 2014 (79 FR 40018). 

The NPRM proposed to correct an 

unsafe condition for the specified 

products. 

Actions Since Previous NPRM Was 

Issued 

Since we issued the NPRM (79 FR 

40018, July 11, 2014), we found that we 

included a cost for parts in the Costs of 

Compliance paragraph. As this 

proposed AD requires an upgrade to 

EEC software, there are no associated 

parts costs. We changed the Costs of 

Compliance paragraph in this proposed 

AD by removing the reference to parts 

costs. 

We changed paragraph (e) of this 

proposed AD to more clearly state the 

requirement to modify affected engines 

either by installing upgraded software in 

the EEC, or by installing an EEC with 

upgraded software incorporated. 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

70476 Federal Register / Vol. 79, No. 228 / Wednesday, November 26, 2014 / Proposed Rules 

We changed paragraph (f) of this 

proposed AD to more clearly prohibit 

installation of an EEC that incorporates 

a software standard earlier than Version 

B7.2 into any engine, and also prohibit 

installation of any software standard 

earlier than Version B7.2 into any EEC. 

Comments 

We received no comments on the 

NPRM (79 FR 40018, July 11, 2014). 

FAA’s Determination 

We are proposing this SNPRM 

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. Certain changes 

described above expand the scope of the 

NPRM (79 FR 40018, July 11, 2014). As 

a result, we have determined that it is 

necessary to reopen the comment period 

to provide additional opportunity for 

the public to comment on this SNPRM. 

Proposed Requirements of This SNPRM 

This SNPRM would require 

accomplishing the actions specified in 

the NPRM, except as discussed under 

‘‘Actions Since Previous NPRM was 

Issued.’’ 

Costs of Compliance 

We estimate that this proposed AD 

affects about 140 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 2 

hours per engine to comply with this 

proposed AD. The average labor rate is 

$85 per hour. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $23,800. 

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), 

(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 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 adding 

the following new airworthiness 

directive (AD): 

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

0328; Directorate Identifier 2014–NE– 

07–AD. 

(a) Comments Due Date 

We must receive comments by December 

10, 2014. 

(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. 

(d) Reason 

This AD was prompted by failure of the 

intermediate pressure (IP) turbine disk drive 

arm and subsequent overspeed and burst of 

the IP turbine disk on an RR RB211 Trent 

turbofan engine. We are issuing this AD to 

prevent overspeed of the IP turbine disk, 

resulting in failure of the turbine blades or 

the IP turbine disk and subsequent 

uncontained release of the disk and/or 

turbine blades, which could lead to damage 

to the engine and damage to the airplane. 

(e) Actions and Compliance 

(1) Unless already done, within 12 months 

after the effective date of this AD, modify the 

engine by removing electronic engine control 

(EEC) software earlier than Version B7.2. 

(2) Install EEC software eligible for 

installation. 

(f) Installation Prohibition 

After modification of an engine as required 

by paragraph (e) of this AD, do not install any 

EEC that incorporates a software standard 

earlier than Version B7.2 into any engine, or 

install any software standard earlier than 

Version B7.2 into any EEC. 

(g) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

FAA, may approve AMOCs to this AD. Use 

the procedures found in 14 CFR 39.19 to 

make your request. You may email your
