Airworthiness Directives; Turbomeca 

Arriel 1 Series Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Metallurgical non-conformities have been 

found when performing quality inspections 

during production of Arriel 1 gas generator 

(GG) second stage turbine discs introduced 

by Turbomeca Modification TU347 (P/N 0 

292 25 040 0). Analysis has concluded that 

the approved life limit of the post-TU347 GG 

second stage turbine disc needs to be reduced 

to 2,500 GG cycles. 

We are issuing this AD to prevent 

failure of the gas generator second stage 

turbine disc which could result in the 

release of high energy debris and 

damage to the helicopter. 

DATES: This AD becomes effective 

October 6, 2010. 

We must receive comments on this 

AD by October 21, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, previously issued EASA 

AD 2010–0101–E, dated June 4, 2010, 

and has now issued a revision to that 

AD, which is AD 2010–0101R1, dated 

August 4, 2010 (referred to after this as 

‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Metallurgical non-conformities have been 

found when performing quality inspections 

during production of Arriel 1 gas generator 

(GG) second stage turbine discs introduced 

by Turbomeca Modification TU347 (P/N 0 

292 25 040 0). Analysis has concluded that 

the approved life limit of the post-TU347 GG 

second stage turbine disc needs to be reduced 

to 2,500 GG cycles. 

Since issuance of AD 2010–0101–E, 

Turbomeca has introduced a reinforced 

Eddy-current inspection which provides a 

lower (improved) detection threshold of the 

metallurgical non-conformities. This 

reinforced Eddy-current inspection, named 

‘‘CFR’’, combined with a revised analysis, 

allows to increase the life limit of the postTU347 GG second Stage Turbine Discs 

identified as ‘‘CFR’’ over the 2,500 GG life 

cycles of the ‘‘non-CFR’’ Discs. 

You may obtain further information by 

examining the MCAI in the AD docket. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of France, and is 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with France, they have 

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: 

• For gas generator second stage 

turbine discs, part number (P/N) 0 292 

25 040 0 that do not have the ‘‘CFR’’ 

marking, removing them from service 

before exceeding 2,500 cycles-in-service 

(CIS) since-new or within 20 CIS from 

the effective date of the AD, whichever 

occurs later; and 

• For gas generator second stage 

turbine discs, P/N 0 292 25 040 0 that 

have the ‘‘CFR’’ marking, removing them 

from service before exceeding 3,500 CIS 

since-new. 

Differences Between the AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. This 

AD differs from the MCAI and/or 

service information as follows: 

• EASA AD 2010–0101R1, dated 

August 4, 2010, requires second stage 

turbine discs with fewer than 2,500 CIS 

to be removed upon accumulating 2,500 

CIS. 

• EASA AD 2010–0101R1, dated 

August 4, 2010, requires revising the 

approved aircraft maintenance program 

to reflect the life limit of 2,500 CIS. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because of the short compliance 


hsrobinson on DSK69SOYB1PROD with RULES
57372 Federal Register / Vol. 75, No. 182 / Tuesday, September 21, 2010 / Rules and Regulations 

time in removing affected gas generator 

second stage discs that are near or over 

the reduced life limit. Therefore, we 

determined that notice and opportunity 

for public comment before issuing this 

AD are impracticable and that good 

cause exists for making this amendment 

effective in fewer 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–2010–0710; 

Directorate Identifier 2010–NE–26–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 

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.

the geographic coordinates of the airport 

to aid in the navigation of our National 

Airspace System.

SUPPLEMENTARY INFORMATION: 

History 

The FAA received a request from the 

National Aeronautical Navigation 

Services to correct the geographic 

coordinates for Opa Locka Airport in the 

Class D airspace for Miami and 

Hollywood, FL. This action makes the 

adjustment. 

The Rule 

This amendment to Title 14, Code of 

Federal Regulations (14 CFR) part 71 

amends Class D airspace at Miami, and 

Hollywood, FL. The geographic 

coordinates of the Opa Locka Airport 

will be corrected to coincide with the 

FAAs National Aeronautical Navigation 

Services. Accordingly, since this is an 

administrative change, and does not 

involve a change in the dimensions or 

operating requirements of that airspace, 

notice and public procedures under 5 

U.S.C. 553(b) are unnecessary. 

The Class D airspace designations are 

published in Paragraph 5000 of FAA 

order 7400.9U, signed August 18, 2010, 

and effective September 15, 2010, which 

is incorporated by reference in 14 CFR 

71.1. The Class D airspace designations 

listed in this document will be 

published subsequently in the Order. 

The FAA has determined that his 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them, operationally 

current, is non-controversial and 

unlikely to result in adverse or negative 

comments. It, therefore, (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); and (3) does not 

warrant preparation of a Regulatory 

Evaluation as the anticipated impact is 

so minimal. Since this is a routine 

matter that will only affect air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. 

This rulemaking is promulgated 

under the authority described in subtitle 

VII, part A, subpart I, section 40103. 

Under that section, the FAA is charged 

with prescribing regulations to assign 

the use of airspace necessary to ensure 

the safety of aircraft and the efficient 

use of airspace. This regulation is 

within the scope of that authority as it 

amends controlled airspace at Miami 

and Hollywood, FL.
