Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

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. 

This proposed AD was prompted by 

failure of the intermediate pressure (IP) 

turbine disk drive arm on an RR RB211 

Trent turbofan engine. This proposed 

AD would 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. We are proposing this AD 

to prevent overspeed failure of the 

turbine blades or the IP turbine disk, 

which could lead to uncontained blade 

or disk release, damage to the engine, 

and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by September 9, 2014. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2014– 

0051, dated March 6, 2014 (referred to 

hereinafter as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

A Trent engine experienced an engine 

internal fire, caused by combustion of carbon 

deposits inside the high/intermediate (HP/IP) 

oil vent tubes. The consequent chain of 

events resulted in the failure of the IP turbine 

disk drive arm. Similar engine architecture 

exists on Trent 800 series engines. 

This condition, if not corrected, could lead 

to uncontained multiple turbine blade 

failures or an IP turbine disk burst, possibly 

resulting in damage to, and reduced control 

of, the aeroplane. 

This AD requires incorporating a 

revised EEC software standard that can 

prevent an unsafe chain of events that 

occur subsequent to an internal engine 

fire. The revised EEC software standard 

can properly adjust fuel flow, shut 

down the engine, prevent an overspeed 

condition, and indirectly extinguish the 

fire. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2014– 

0328. 

Relevant Service Information 

RR has issued Alert Service Bulletin 

No. RB.211–73–AH001, dated July 17, 

2013. The ASB provides guidance for 

removal and replacement of the affected 

EEC. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of the United 

Kingdom, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information provided by EASA and 

determined the unsafe condition exists 


sroberts on DSK5SPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 133 / Friday, July 11, 2014 / Proposed Rules 40019 

and is likely to exist or develop on other 

products of the same type design. This 

proposed AD would require 

modification of the engine by removing 

any EEC that incorporates EEC software 

standard prior to version B7.2 and 

installing an EEC eligible for 

installation. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 140 engines installed 

on airplanes of U.S. registry. We also 

estimate that it would take about 2 

hours per product to comply with this 

proposed AD. The average labor rate is 

$85 per hour. Required parts cost about 

$170. 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 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 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.

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 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 September 

9, 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 on an RR RB211 Trent turbofan engine. 

We are issuing this AD to prevent overspeed 

failure of the turbine blades or the IP turbine 

disk, which could lead to uncontained blade 

or disk release, damage to the engine, and 

damage to the airplane. 

(e) Actions and Compliance 

Unless already done, within 12 months 

after the effective date of this AD, remove any 

electronic engine control (EEC) that 

incorporates EEC software standard prior to 

version B7.2 and install an EEC eligible for 

installation. 

(f) Installation Prohibition 

After modification of an engine as required 

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

EEC that incorporates a software standard 

prior to version B7.2 onto any engine. 

(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.
