Federal Register / Vol. 78, No. 36 / Friday, February 22, 2013 / Proposed Rules 12255 

(a) To what extent do you believe the 

current rotorcraft certification standards 

need to be amended to remain relevant 

over the next 20 years, given the rapid 

pace of advances in technology? 

(b) Should the current rotorcraft 

certification standards be completely 

changed, or are weight and number of 

passengers still relevant for determining 

certification? 

(c) If you believe certification should 

continue to be based on weight and 

number of passengers, to what extent 

should the existing standards be 

updated, and how? 

(d) As revisions to regulatory 

certification standards would require 

participation in a rulemaking committee 

over a substantial period of time, to 

what extent would you be willing to 

participate? 

As a convenience, these questions are 

available for submission in the same 

format as above at the following Web 

site link: http://www.faa.gov/aircraft/ 

air_cert/design_approvals/rotorcraft/ 

comm. 

If the FAA decides to have further 

rulemaking discussions on these issues, 

we will issue a document, giving the 

public another opportunity to comment.

Airworthiness Directives; Rolls-Royce 

(1971) Limited, Bristol Engine Division 

Turbojet 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 (1971) Limited, Bristol 

Engine Division (RR) Viper Mk. 601–22 

turbojet engines. This proposed AD was 

prompted by a review carried out by RR 

of the lives of certain critical parts. This 

proposed AD would require reducing 

the life of these parts. We are proposing 

this AD to prevent life-limited part 

failure, damage to the engine, and 

damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by April 23, 2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov and follow 

the instructions for sending your 

comments electronically. 

• Mail: U.S. Department of 

Transportation, 1200 New Jersey 

Avenue SE., West Building Ground 

Floor, Room W12–140, Washington, DC

address above between 9 a.m. and 5 

p.m., Monday through Friday, except 

Federal holidays.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0243 

(Correction: November 13, 2012), dated 

November 12, 2012, a Mandatory 

Continuing Airworthiness Information 

(referred to hereinafter as ‘‘the MCAI’’), 

to correct an unsafe condition for the 

specified products. The MCAI states: 

A review, carried out by Rolls-Royce, of the 

lives of critical parts of the Viper Mk. 601– 

22 engine, has resulted in reduced cyclic life 

limits for certain critical parts. 

Operation of critical parts beyond these 

reduced cyclic life limits may result in part 

failure, possibly resulting in the release of 

high-energy debris, which may cause damage 

to the aeroplane and/or injury to the 

occupants. 

For the reasons described above, this AD 

requires implementation of the reduced 

cyclic life limits for the affected critical parts, 

i.e., replacement of each part before the 

applicable reduced life limit is exceeded, and 

replacement of those critical parts that have 

already exceeded the reduced cyclic life 

limits. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

RR Alert Service Bulletin 72–A206, 

dated November, 2012. 

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 


pmangrum on DSK3VPTVN1PROD with PROPOSALS-1
12256 Federal Register / Vol. 78, No. 36 / Friday, February 22, 2013 / Proposed Rules 

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 

and is likely to exist or develop on other 

products of the same type design. This 

proposed AD would require reducing 

the life of certain critical parts. 

Costs of Compliance 

We estimate that this proposed AD 

affects 32 engines installed on airplanes 

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

would take 0 hours per product to 

comply with this proposed AD. The 

average labor rate is $85 per hour. We 

are not requiring parts replacement, so 

parts cost is $0. We estimate the cost of 

the proposed AD on U.S. operators to be 

$0. 

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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

Airworthiness Directives; Embraer S.A. 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Embraer S.A. Model ERJ 170 and ERJ 

190 airplanes. This proposed AD was 

prompted by reports of chafing between 

the auxiliary power unit (APU) 

electronic starter controller (ESC) power 

cables and the airplane tail cone 

firewall. This proposed AD would 

require a detailed inspection for damage 

to the insulation and inner conductors 

of the APU ESC power cables, installing
