Called A300–600 Series Airplanes) 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

An operator reported several cases of wire 

damages at the pylon/wing interface. 

Analysis revealed that wires damages are due 

to installation quality issue resulting from 

lack of information in installation drawings 

and job cards. 

Moreover detailed analysis has highlighted 

that the Low Pressure Valve (LPV) wires were 

not segregated by design. 

* * * * * 

If left uncorrected, the wire chafing could 

impact fire protection and detection system. 

It may also induce dormant failure on LPV 

preventing its closure leading to a permanent 

and uncontrolled fire (in case of fire ignited 

upstream the High Pressure Valve (HPV)). 

* * * * * 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by May 6, 2011.

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 2010–0178, 

dated August 23, 2010 (referred to after 

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

condition for the specified products. 

The MCAI states: 

An operator reported several cases of wire 

damages at the pylon/wing interface. 

Analysis revealed that wires damages are due 

to installation quality issue resulting from 

lack of information in installation drawings 

and job cards. 

Moreover detailed analysis has highlighted 

that the Low Pressure Valve (LPV) wires were 

not segregated by design. 

Due to design similarities, A310, A300–600 

and A300–600ST aeroplanes can be affected, 

depending on the wires installation in the 

concerned area. 

If left uncorrected, the wire chafing could 

impact fire protection and detection system. 

It may also induce dormant failure on LPV 

preventing its closure leading to a permanent 

and uncontrolled fire (in case of fire ignited 

upstream the High Pressure Valve (HPV)). 

For the reasons explained above, this AD 

requires the modification of the electrical 

installation in the pylon/wing interface to 

avoid wire damages. 

The modification includes a general 

visual inspection of wires for damage. 

and repair if necessary. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletin A300–24–6106, including 

Appendix 01, dated March 31, 2010; 

and Mandatory Service Bulletin A310– 

24–2106, including Appendix 01, dated 

May 27, 2010. 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 Proposed 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 proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 


srobinson on DSKHWCL6B1PROD with PROPOSALS
Federal Register / Vol. 76, No. 55 / Tuesday, March 22, 2011 / Proposed Rules 15871 

develop on other products of the same 

type design. 

Differences Between This 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 proposed 

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 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 185 products of U.S. 

registry. We also estimate that it would 

take about 16 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $1,170 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these costs. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$468,050, or $2,530 per product. 

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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

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 proposed AD and placed it in the 

AD docket.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

* * * * * 

The airworthiness limitations applicable to 

the Safe Life Airworthiness Limitation Items 

(SL ALI) are given in Airbus A330 ALS Part 

1 and A340 ALS Part 1, which are approved 

by the European Aviation Safety Agency 

(EASA). 

The revision 05 of Airbus A340 ALS Part 

1 introduces more restrictive maintenance 

requirements and/or airworthiness 

limitations. Failure to comply with this 

revision constitutes an unsafe condition. 

For A330 aeroplanes, this EASA AD retains 

the requirements of EASA AD 2010–0131, 

which it supersedes. 

For A340 aeroplanes, this EASA AD 

supersedes EASA AD 2009–0192, and 

requires the implementation of the new or 

more restrictive maintenance requirements 

and/or airworthiness limitations as specified 

in Airbus A340 ALS Part 1, revision 05. 

The unsafe condition is fatigue cracking, 

damage, and corrosion in certain 

structure, which could result in reduced 

structural integrity of the airplane. The 

proposed AD would require actions that 

are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by May 6, 2011.

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2010–0253, 

dated December 3, 2010 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

The airworthiness limitations are currently 

distributed in the Airbus A330 Airworthiness 

Limitations Section (ALS) and A340 ALS. 

The airworthiness limitations applicable to 

the Safe Life Airworthiness Limitation Items 

(SL ALI) are given in Airbus A330 ALS Part
