AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Airbus Model A330–200, A330–300, 

A340–200 and A340–300 series 

airplanes. This proposed AD was 

prompted by a report that revealed the 

wheel axles of the main landing gear 

(MLG) were machined with a radius as 

small as 0.4 millimeters. This proposed 

AD would require replacing the wheel 

axle of the MLG with a serviceable part. 

We are proposing this AD to prevent 

fatigue of the wheel axle of the MLG, 

which could adversely affect the 

structural integrity of the airplane. 

DATES: We must receive comments on 

this proposed AD by October 11, 2012. 

ADDRESSES: You may send comments by 

any of the following methods:

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 2011–0170, 

dated September 7, 2011 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

EASA has received a report via Airbus and 

Messier-Bugatti-Dowty Ltd, from a 

Maintenance repair organisation, concerning 

a specific repair, accomplished on certain 

MLG wheel axles. Investigations revealed 

that the axles have been machined with a 

radius as small as 0.4 mm. 

This condition, if not corrected, has a 

detrimental effect on the fatigue lives of these 

parts, possibly affecting the structural 

integrity of the aeroplane. Fatigue analyses 

were performed, the results of which 


pmangrum on DSK3VPTVN1PROD with PROPOSALS-1
51730 Federal Register / Vol. 77, No. 166 / Monday, August 27, 2012 / Proposed Rules 

indicated that the life limit of the affected 

MLG wheel axles must be reduced to below 

the one stated in the A330 and A340 Airbus 

Airworthiness Limitation Section (ALS) Part 

1. 

For the reasons described above, this 

[EASA] AD requires the replacement of the 

MLG wheel axles before reaching the new 

reduced demonstrated life limit. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued All Operator Telex 

A330–32A3256, dated August 24, 2011, 

including Appendix 1, dated August 23, 

2011 (for Model A330–200 and –300 

series airplanes); and All Operator Telex 

A340–32A4292, dated August 24, 2011, 

including Appendix 1, dated August 23, 

2011 (for Model A340–200 and –300 

series airplanes). 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 

develop on other products of the same 

type design. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 59 products of U.S. registry. 

We also estimate that it would take 

about 48 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 $153,443 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 parts. 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 

$9,293,857, or $157,523 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); 

3. Will not affect intrastate aviation in 

Alaska; and 

4. 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. 

List of Subjects in 14 CFR Part 39
