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) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI (European Aviation 

Safety Agency AD 2009–0192) describes 

the unsafe condition as: 

Performing some quality tests on material, 

Airbus found that some 300M steel forgings 

used to manufacture certain landing gear 

components were below specification limits. 

Adapted airworthiness limitations were 

introduced in Airbus A340 Airworthiness 

Limitations Section (ALS) Part 1 ‘‘Safe Life 

Airworthiness Limitation Items (SL ALI)’’ for 

different source route codes. 

* * * * * 

This [EASA] AD introduces more 

restrictive life limitations for several landing 

gear components. 

The MCAI (EASA AD 2010–0131) 

describes the unsafe condition as: 

* * * * * 

The revision 04 of Airbus A330 and A340 

ALS Part 1 introduces more restrictive 

maintenance requirements and/or 

airworthiness limitations as specified in 

Airbus A330 and A340 ALS Part 1 revision 

04. 

The unsafe condition is failure of 

certain life-limited parts, which could 

result in reduced structural integrity of 

the airplane. This AD requires actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective 

March 2, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of March 2, 2011. 

We must receive comments on this 

AD by April 1, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the aviation authority 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directives 2010–0131, 

dated June 28, 2010 and EASA AD 

2009–0192, dated August 28, 2009 

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

correct an unsafe condition for the 

specified products. The MCAI (EASA 

AD 2009–0192) states: 

Performing some quality tests on material, 

Airbus found that some 300M steel forgings 

used to manufacture certain landing gear 

components were below specification limits. 

Adapted airworthiness limitations were 

introduced in Airbus A340 Airworthiness 

Limitations Section (ALS) Part 1 ‘‘Safe Life 

Airworthiness Limitation Items (SL ALI)’’ for 

different source route codes. 

A new source route (S3) has since been 

investigated and has led to another set of 

adapted airworthiness limitations for affected 

main fittings. 

In addition, further tests based on a new 

method for damage load selection led to the 

limitation changes for A340–500/–600 centre 

landing gear main fitting part number (P/N) 

50–1105236–01 and P/N 1105296–00. 

This [EASA] AD introduces more 

restrictive life limitations for several landing 

gear components. 

The MCAI (EASA AD 2010–0131) 

describes the unsafe condition as: 

The airworthiness limitations are currently 

distributed in the Airbus A330 and A340 

Airworthiness Limitations Section (ALS). 

The airworthiness limitations applicable to 

the Safe Life Airworthiness Limitation Items 

(SL ALI) are given in Airbus A330 and A340 

ALS Part 1, which are approved by the 

European Aviation Safety Agency (EASA). 

The revision 04 of Airbus A330 and A340 

ALS Part 1 introduces more restrictive 

maintenance requirements and/or 

airworthiness limitations as specified in 

Airbus A330 and A340 ALS Part 1 revision 

04. 

This new [EASA] AD supersedes EASA AD 

2007–0300, EASA AD 2008–0152 and EASA 

AD 2009–0191 and requires the 

implementation of the new or more 

restrictive maintenance requirements and/or 

airworthiness limitations as specified in 

Airbus A330 and A340 ALS Part 1 revision 

04. 

The unsafe condition is failure of 

certain life-limited parts, which could 

result in reduced structural integrity of 

the airplane. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Airbus has issued A340 ALS Part 1, 

Safe Life Airworthiness Limitation 

Items Revision 05, dated July 29, 2010. 

This document provides for mandatory 

replacement times, structural inspection 

intervals, and related structural 

inspection procedures or other 

procedures (e.g., modifications). The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

Other Relevant Rulemaking 

On April 20, 2006, we issued AD 

2006–09–07, Amendment 39–14577 (71 

FR 25919, May 3, 2006), for all Airbus 

Model A330–200 and –300, and A340– 

200 and –300 series airplanes, and 

A340–541 and –642 airplanes. That AD 

requires operators to revise the 

Airworthiness Limitations section of the 

Instructions for Continued 

Airworthiness to incorporate new 

information. That information includes, 

for all affected airplanes, decreased life 

limit values for certain components; and 

for Model A330–200 and –300 series 

airplanes, new inspections, compliance 

times, and new repetitive intervals to 

detect fatigue cracking, accidental 

damage, or corrosion in certain 

structures. That AD results from a 

revision to section 9–1 of the Airbus 

A330 and A340 maintenance planning 

documents (MPDs) for life limits/ 

monitored parts, and section 9–2 of the 

Airbus A330 MPD for airworthiness 

limitations items. Accomplishing the 

revision in paragraph (g) of this AD 

eliminates the need for the revision 

required by paragraph (f)(2) of AD 2006– 

09–07 for Model A340 airplanes. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are issuing this 

AD because we evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

There are no products of this type 

currently registered in the United States. 

However, this rule is necessary to 

ensure that the described unsafe 

condition is addressed if any of these 

products are placed on the U.S. Register 

in the future. 

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. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a Note within the AD. 

FAA’s Determination of the Effective 

Date 

Since there are currently no domestic 

operators of this product, notice and 

opportunity for public comment before 

issuing this AD are unnecessary. 

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–2011–0039; 

Directorate Identifier 2010–NM–184– 

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. 


jdjones on DSK8KYBLC1PROD with RULES
8614 Federal Register / Vol. 76, No. 31 / Tuesday, February 15, 2011 / Rules and Regulations 

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 we receive 

about this AD. 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation

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: 

2011–04–05 Airbus: Amendment 39–16605. 

Docket No. FAA–2011–0039; Directorate 

Identifier 2010–NM–184–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective March 2, 2011. 

Affected ADs 

(b) This AD affects AD 2006–09–07, 

Amendment 39–14577. 

Applicability 

(c) This AD applies to Airbus Model A340– 

211, –212, and –213 airplanes; A340–311, 

–312, and –313 airplanes; A340–541 

airplanes; and A340–642 airplanes; 

certificated in any category; all manufacturer 

serial numbers. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new inspections. Compliance with 

these inspections is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired in 

the areas addressed by these inspections, the 

operator may not be able to accomplish the 

inspections described in the revisions. In this 

situation, to comply with 14 CFR 91.403(c), 

the operator must request approval for an 

alternative method of compliance according 

to paragraph (j)(1) of this AD. The request 

should include a description of changes to 

the required inspections that will ensure the 

continued operational safety of the airplane. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 05. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) (European 

Aviation Safety Agency (EASA) AD 2009– 

0192) states: 

Performing some quality tests on material, 

Airbus found that some 300M steel forgings 

used to manufacture certain landing gear 

components were below specification limits. 

Adapted airworthiness limitations were 

introduced in Airbus A340 Airworthiness 

Limitations Section (ALS) Part 1 ‘‘Safe Life 

Airworthiness Limitation Items (SL ALI)’’ for 

different source route codes. 

* * * * * 

This [EASA] AD introduces more 

restrictive life limitations for several landing 

gear components. 

The MCAI (EASA AD 2010–0131) 

describes the unsafe condition as: 

* * * * * 

The revision 04 of Airbus A330 and A340 

ALS Part 1 introduces more restrictive 

maintenance requirements and/or 

airworthiness limitations as specified in 

Airbus A330 and A340 ALS Part 1 revision 

04. 

The unsafe condition is failure of certain lifelimited parts, which could result in reduced 

structural integrity of the airplane. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Revise the Maintenance Program 

(g) Within 3 months after the effective date 

of this AD: Revise the maintenance program 

by incorporating Airbus A340 ALS Part 1— 

Safe Life Airworthiness Limitation Items (SL 

ALI), Revision 05, dated July 29, 2010. At the 

times specified in the Airbus A340 ALS Part 

1—SL ALI, Revision 05, dated July 29, 2010, 

comply with all applicable maintenance 

requirements and associated airworthiness 

limitations specified in Airbus A340 ALS, 

Part 1—SL ALI, Revision 05, dated July 29, 

2010. 

Alternative Intervals or Limits 

(h) Except as provided by paragraph (j)(1) 

of this AD, after accomplishing the actions 

specified in paragraph (g) of this AD, no 

alternative to the replacements, replacement 

intervals, or limitations specified in 

paragraph (g) of this AD may be used. 

Method of Compliance With Paragraph (f)(2) 

of AD 2006–09–07 

(i) Doing the revision required by 

paragraph (g) of this AD terminates the 

requirements of paragraph (f)(2) of AD 2006– 

09–07 for that Model A340 airplane only. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

Although the MCAI specifies a compliance 

time of ‘‘from the effective date of this AD’’ 

for revising the maintenance program to 

incorporate Airbus A340 ALS Part 1—Safe 

Life Airworthiness Limitation Items, 

Revision 05, dated July 29, 2010; this AD 

requires the action be done within 3 months 

after the effective date of this AD. 

Other FAA AD Provisions 

(j) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane

actions if necessary. This AD also 

requires doing a detailed inspection for 

foreign objects, debris and damage to 

the wall of the track housing of the 

outboard slats, and corrective actions if 

necessary. This AD results from reports 

of broken bolts in the outboard slat main 

track downstop assembly. We are 

issuing this AD to detect and correct 

incorrectly installed main track 

downstop assemblies, which can allow 

the main track downstop hardware to 

fall into the track housing and cause a 

puncture in the track housing when the 

slat is retracted. This condition, if not 

corrected, could result in a fuel leak and 

an increased risk of fire. 

DATES: This AD is effective March 22, 

2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of March 22, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Model 767 airplanes. That 

NPRM was published in the Federal 

Register on April 8, 2010 (75 FR 17887). 

That NPRM proposed to require doing a 

detailed inspection for correct main 

track downstop assembly, thread 

protrusion, and damaged and missing 

parts of the main track downstop 

assemblies of the outboard slats, and 

related investigative and corrective 

actions if necessary. That proposed AD 

also proposed to require doing a 

detailed inspection for foreign objects 

debris and damage to the wall of the 

track housing of the outboard slats, and 

corrective actions if necessary. 

Relevant Service Information 

The NPRM referred to Boeing Special 

Attention Service Bulletin 767–57– 

0118, dated October 8, 2009. We 

reviewed Boeing Special Attention 

Service Bulletin 767–57–0118, Revision 

1, dated October 21, 2010. This service 

bulletin revision adds an option to 

inspect either the bolt or nut for 

looseness by applying torque to the 

main track downstop assembly nut or 

the bolt head, corrects a reference, and 

removes the references to slat numbers 

6 and 7 in Appendix A. This service 

bulletin revision does not add any 

additional work for the affected 

airplanes. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received from 

the commenters. 

Request To Add Boeing Document D–
