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: 

Non-conformities on adjustment of some 

hydromechanical units (HMUs) have been 

reported by a Turbomeca repair centre. The 

technical investigations carried out by 

Turbomeca are showing that only a limited 

number of HMUs are potentially affected by 

this non-conformity to HMU adjustment. 

Twenty nine HMUs have been 

identified with the non-conformities. 

We are issuing this AD to prevent an 

uncommanded inflight shutdown, 

which could result in an emergency 

autorotation landing. 

DATES: This AD becomes effective 

December 14, 2011. 

We must receive comments on this 

AD by December 29, 2011. 

The Director of the Federal Register

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 

Airworthiness Directive 2011–0128–E, 

dated July 6, 2011 (referred to after this 

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

condition for the specified products. 

The MCAI states: 

Non-conformities on adjustment of some 

hydromechanical units (HMUs) have been 

reported by a Turbomeca repair centre. The 

technical investigations carried out by 

Turbomeca are showing that only a limited 

number of HMUs are potentially affected by 

this non-conformity to HMU adjustment. 

Twenty nine HMUs have been 

identified with potential nonconformities in the proper adjustment of 


pmangrum on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 76, No. 229 / Tuesday, November 29, 2011 / Rules and Regulations 73495 

the metering valve. The exact location of 

these 29 HMUs is unknown. This AD 

requires actions to be done before 

further flight. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Turbomeca S.A. has issued Alert 

Mandatory Service Bulletin (SB) No. 

A292 73 2841, Version A, dated July 4, 

2011, SB No. 292 73 2143, dated July 24, 

2007, and SB No. 292 73 2840, Version 

A, dated June 28, 2011. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. The one-time 

functional test required by the service 

bulletin is not a normal engine run-up 

test: the one-time functional test 

involves additional requirements 

including mode switching, that are not 

part of a normal engine run-up after 

start. 

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, 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. 

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 this AD requires either 

replacing, or functional testing of the 

HMU before further flight. 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–2011–1031; 

Directorate Identifier 2011–NE–27–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.

Reason 

(d) 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: 

Non-conformities on adjustment of some 

hydromechanical units (HMUs) have been 

reported by a Turbomeca repair centre. The 

technical investigations carried out by 

Turbomeca are showing that only a limited 

number of HMUs are potentially affected by 

this non-conformity to HMU adjustment. 

Twenty nine HMUs have been identified 

with potential non-conformities in the proper 

adjustment of the metering valve. The exact 

location of these 29 HMUs is unknown. We 

are issuing this AD to prevent an 

uncommanded inflight shutdown, which 

could result in an emergency autorotation 

landing. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

(f) Before further flight, perform a one-time 

functional test of the engine to confirm 

proper engine operation. This one-time 

functional test is not a normal engine run-up 

test. Use the instructions in paragraph 

2.B.(1)(a) of Turbomeca Alert Mandatory 

Service Bulletin No. A292 73 2841, Version 

A, dated July 4, 2011, to perform the 

functional test. 

(1) If the engine fails the functional test, 

replace the HMU with an HMU eligible for 

installation. 

(2) If the engine passes the functional test, 

do the following: 

(i) Within four months after the effective 

date of this AD, install software modification 

TU143 on the Engine Electronic Control Unit 

of the engine. Use paragraph 2.B. of 

Turbomeca Service Bulletin No. 292 73 2143, 

dated July 24, 2007 to do the installation; and 

(ii) Within 12 months after the effective 

date of this AD, replace the HMU with an 

HMU eligible for installation. 

Definition 

(g) For the purpose of this AD, an HMU 

eligible for installation is defined as one with 

a serial number not listed in Table 1 of this 

AD, or, an HMU that passed when tested 

using Turbomeca Service Bulletin No. 292 73 

2840. 

FAA AD Differences 

(h) None. 

Alternative Methods of Compliance 

(AMOCs) 

(i) The Manager, Engine Certification 

Office, FAA, may approve AMOCs for this 

AD. Use the procedures found in 14 CFR

–301, –302, –303, –321, –322, –323, 

–341, –342, and –343 airplanes; and 

Model A340–200 and –300 series 

airplanes. This AD results from 

mandatory continuing airworthiness 

information (MCAI) originated 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: 

During A330 and A340 aeroplanes fatigue 

tests, cracks appeared on the right (RH) and 

left (LH) sides between the crossing area of 

the keel beam fitting and the front spar of the 

Centre Wing Box (CWB). This condition, if 

not corrected, could lead to keel beam 

rupture which would affect the area 

structural integrity.

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

January 3, 2012.
