AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Rolls-Royce Deutschland Ltd & Co KG 

(RRD) Model Tay 620–15 turbofan 

engines. This AD requires a one-time 

inspection of the low-pressure 

compressor (LPC) fan blades and if 

erosion is found their replacement 

before further flight. This AD was 

prompted by evidence of excessive 

leading edge erosion of the LPC fan 

blades on certain Tay 620–15 engines. 

We are issuing this AD to prevent 

failure of the LPC fan blade, which 

could result in uncontained engine 

failure and damage to the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Emergency Airworthiness Directive 

2012–0234, dated November 6, 2012 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

The Low Pressure Compressor (LPC) (fan) 

blades of certain Tay 620/15/20 and Tay 620– 

15 engines show evidence of excessive 

leading edge erosion. Excessive material 

removal during the maintenance reduces the 

LPC (fan) blade chordal width and 

potentially changes the balance of the fan 

blade. Reduced chordal width can affect LPC 

(fan) blade performance and in combination 

with other circumstances could lead to a fan 

blade root failure and fan blade separation. 

This condition, if not detected and corrected, 

could lead to the LPC (fan) blade failure, 

potentially causing release of high-energy 

debris, possibly resulting in damage to the 

aeroplane and/or injury to the occupants. 

We are issuing this AD to prevent 

failure of the LPC fan blade, which 

could result in uncontained engine 

failure and damage to the airplane. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

RRD has issued Alert NonModification Service Bulletin TAY–72– 

A1777, dated October 26, 2012. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

Germany 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 issuing 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 

AD requires a one-time inspection of the 

LPC fan blades and if erosion is found 

their replacement before further flight. 

FAA’s Determination of the Effective 

Date 

No domestic operators use this 

product. Therefore, we find that notice 

and opportunity for prior public 

comment are unnecessary and that good 

cause exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2012–1350; 

Directorate Identifier 2012–NE–40–AD’’ 

at the beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact with FAA 

personnel concerning this AD. Using the 

search function of the Web site, anyone 

can find and read the comments in any 

of our dockets, including, if provided, 

the name of the individual who sent the 

comment (or signed the comment on 

behalf of an association, business, labor 

union, etc.). You may review the DOT’s 

complete Privacy Act Statement in the 


wreier-aviles on DSK5TPTVN1PROD with 
2198 Federal Register / Vol. 78, No. 7 / Thursday, January 10, 2013 / Rules and Regulations 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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 AD: 

2012–27–01 Rolls-Royce Deutschland Ltd & 

Co KG (Formerly Rolls-Royce plc, 

Derby, England): Amendment 39–17313; 

Docket No. FAA–2012–1350; Directorate 

Identifier 2012–NE–40–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective January 25, 2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Rolls-Royce

this AD to prevent failure of the LPC fan 

blade, which could result in uncontained 

engine failure and damage to the airplane. 

(e) Actions and Compliance 

Unless already done, do the following. 

(1) Before the next flight after the effective 

date of the AD, inspect the leading edge of 

the LPC fan blades and determine if 

excessive erosion is evident. Guidance on 

conducting the inspection can be found in 

RRD Alert Non-Modification Service Bulletin 

(NMSB) TAY–72–A1777, dated October 26, 

2012. 

(2) If the measured blade chordal width is 

outside the requirements, before the next 

flight, replace the complete set of LPC fan 

blades with a set of LPC fan blades eligible 

for installation. 

(3) Within 30 days after performing the 

inspection required by paragraph (e)(1) of 

this AD, provide, for all repaired blades, the 

actual chordal width measurement to RRD, 

Service Engineering.

Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Turbomeca S.A. Arriel 1A1, 1A2, 1B, 

1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, 

and 1S1 turboshaft engines. This AD 

requires performing a high gas generator
