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 describes the unsafe 

condition as: 

A review of A340 missions has 

demonstrated that CFM56–5C forward engine 

mount thrust links fitted with oversized 

bearing[s] will not reach the updated link 

fatigue life limit of 15500 Flight Cycles (FC) 

due to an increase in bore diameter. 

* * * The consequent potential failure of 

the affected thrust link would reduce the 

forward engine mounts’ structural integrity 

and could eventually lead to engine 

separation, constituting an unsafe condition. 

* * * * * 

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective 

March 12, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD

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 2009–0108, 

dated May 5, 2009 (referred to after this 

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

condition for the specified products. 

The MCAI states: 

A review of A340 missions has 

demonstrated that CFM56–5C forward engine 

mount thrust links fitted with oversized 

bearing[s] will not reach the updated link 

fatigue life limit of 15,500 Flight Cycles (FC) 

due to an increase in bore diameter. 

Oversized bearing repairs have been 

possible through the accomplishment of 

CMM 71–21–12 Repair 1. The consequent 

potential failure of the affected thrust link 

would reduce the forward engine mounts’ 

structural integrity and could eventually lead 

to engine separation, constituting an unsafe 

condition. 

Consequently, this AD requires: 

—The [detailed] inspection of the link 

assembly to identify a possible oversized 

bearing repair and, in case of finding, the 

application of the associated corrective 

actions, or 

—The repetitive [detailed] inspection [for 

cracking, damage (e.g., dents), and missing 

fasteners] of the forward engine mounts 

until accomplishment of the inspection of 

the link assembly for the identification of 

a possible oversized bearing repair. 

The corrective actions for finding 

oversized bearings in the forward engine 

mount thrust link assembly include 

contacting Goodrich for instructions and 

doing the repair. The corrective actions 

for finding cracking, damage (e.g., 

dents), and missing fasteners in the 

forward engine mounts include, 

depending on the findings, replacing 

cracked parts and missing fasteners, and 

polishing damaged areas. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletin A340–71–4007, including 

Appendix 1, dated April 1, 2009. 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 

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.

8472 Federal Register / Vol. 75, No. 37 / Thursday, February 25, 2010 / Rules and Regulations 

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–2010–0131; 

Directorate Identifier 2009–NM–132– 

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 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.

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: 

2010–05–07 Airbus: Amendment 39–16216. 

Docket No. FAA–2010–0131; Directorate 

Identifier 2009–NM–132–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective March 12, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all Airbus Model 

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

Model A340–311, –312, and –313 series 

airplanes; certificated in any category. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 71: Powerplant. 

Reason 

(e) The mandatory continued airworthiness 

information (MCAI) states: 

A review of A340 missions has 

demonstrated that CFM56–5C forward engine 

mount thrust links fitted with oversized 

bearing[s] will not reach the updated link 

fatigue life limit of 15500 Flight Cycles (FC) 

due to an increase in bore diameter. 

Oversized bearing repairs have been 

possible through the accomplishment of 

CMM 71–21–12 Repair 1. The consequent 

potential failure of the affected thrust link 

would reduce the forward engine mounts 

structural integrity and could eventually lead 

to engine separation, constituting an unsafe 

condition. 

Consequently, this AD requires: 

—The [detailed] inspection of the link 

assembly to identify a possible oversized 

bearing repair and, in case of finding, the 

application of the associated corrective 

actions, or 

—The repetitive [detailed] inspection [for 

cracking, damage (e.g., dents), and missing 

fasteners] of the forward engine mounts 

until accomplishment of the inspection of 

the link assembly for the identification of 

a possible oversized bearing repair. 

The corrective actions for finding oversized 

bearings in the forward engine mount thrust 

link assembly include contacting Goodrich 

for instructions and doing the repair. The 

corrective actions for finding cracking, 

damage (e.g., dents), and missing fasteners in 

the forward engine mounts include, 

depending on the findings, replacing cracked 

parts and missing fasteners, and polishing 

damaged areas. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 1,700 flight cycles or 24 months 

from the effective date of this AD, whichever 

occurs first: Do the actions required by 

paragraph (f)(1)(i) or (f)(1)(ii) of this AD. 

(i) Perform a detailed inspection for 

oversized bearing repair of the forward 

engine mount thrust link assembly, in 

accordance with the Accomplishment 

Instructions of Airbus Mandatory Service 

Bulletin A340–71–4007, dated April 1, 2009. 

If oversized bearings are found, before further 

flight, contact Goodrich for instructions, and 

do the repair. 

(ii) Perform a detailed inspection of the 

forward engine mounts for cracking, damage 

(e.g., dents), and missing fasteners, in 

accordance with Task 71–21–11–210–801–0 

of the Airbus A340 Aircraft Maintenance 

Manual, Revision 68, dated October 1, 2009. 

Do all applicable corrective actions before 

further flight in accordance with Task 71–21– 

11–210–801–0 of the Airbus A340 Aircraft 

Maintenance Manual, Revision 68, dated 

October 1, 2009. Repeat the inspection 

thereafter at intervals not to exceed 1,700 

flight cycles or 24 months, whichever occurs 


jlentini on DSKJ8SOYB1PROD with RULES
Federal Register / Vol. 75, No. 37 / Thursday, February 25, 2010 / Rules and Regulations 8473 

first, until the inspection required by 

paragraph (f)(2) of this AD is done. 

(2) For airplanes on which the inspection 

specified in paragraph (f)(1)(ii) of this AD is 

done: Within 4,500 flight cycles from the 

effective date of this AD, do the inspection 

and applicable corrective actions required by 

paragraph (f)(1)(i) of this AD. Doing the 

inspection and applicable corrective actions 

required by paragraph (f)(1)(i) of this AD 

terminates the repetitive inspections required 

by paragraph (f)(1)(ii) of this AD. 

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: 

Airbus Mandatory Service Bulletin A340– 

71–4007, dated April 1, 2009; does not 

contain corrective actions if damage is found 

during the inspection of the forward engine 

mounts. The corrective actions are specified 

in Task 71–21–11–210–801–0 of the Airbus 

A340 Aircraft Maintenance Manual, Revision 

68, dated October 1, 2009. Therefore, this AD 

refers to Task 71–21–11–210–801–0 of the 

Airbus A340 Aircraft Maintenance Manual, 

Revision 68, dated October 1, 2009, for the 

inspection and corrective actions. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing 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: 

Field reports have indicated that the 

possibility exists that both Primary Flight 

Displays (PFDs) could indicate a roll attitude 

offset of up to 10 degrees in the same 

direction if an accelerated turn onto the 

active runway is performed immediately 

followed by take-off. In addition, 

annunciated heading splits have been 

reported. This condition has been reported to 

correct itself after several minutes. 

Additionally, if the aeroplane is operating 

in geographical latitudes with low horizontal 

magnetic field strength, incorrect heading 

may be displayed if the ADAHRS switches 

from GPS track to magnetometer heading 

while the aeroplane is on the ground.
