SUPPLEMENTARY INFORMATION: tkelley on DSK3SPTVN1PROD with SUMMARY: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR VerDate Mar<15>2010 05:50 Dec 22, 2012 Jkt 229001 part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on September 12, 2012 (77 FR 56172). That NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (MCAI) states: During ground load test cycles on an A340–600 aeroplane, the MLG bogie beam has prematurely fractured. The results of the investigation identified that this premature fracture was due to high tensile standing stress, resulting from dry fit axle assembly method. Improvement has been introduced subsequently with a grease fit axle assembly method. Fatigue and damage tolerance analyses were performed, whose results demonstrated that the current life limit of certain MLG bogie beams with dry fit axles installed on A330 aeroplanes only must be reduced compared to the life limit stated in the A330 Airworthiness Limitations Section (ALS) Part 1-Safe Life Airworthiness Limitation Items revision 05 approved by EASA [European Aviation Safety Agency] on 29 July 2010. Failure to comply with the reduced life limit of the MLG bogie beam with dry fit axle might jeopardize the MLG structural integrity. For the reasons described above, this [EASA] AD requires the replacement of the affected MLG bogie beams before reaching the new reduced life limit. The unsafe condition is a possible fracture of the MLG bogie beam, which, under high speed, could ultimately result in the airplane departing the runway, the bogie beam detaching from the airplane, or collapse of the MLG; and consequent structural damage to the airplane and injury to the occupants. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (77 FR 56172, September 12, 2012) or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (77 FR 56172, September 12, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 56172, September 12, 2012). PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 75825 Costs of Compliance We estimate that this AD will affect 53 products of U.S. registry. We also estimate that it will take about 16 workhours per MLG bogie beam (2 MLG bogie beams per airplane) to comply with the basic requirements of this AD. The average labor rate is $85 per workhour. Required parts will cost about $255,000 per MLG bogie beam. 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 this AD to the U.S. operators to be up to $27,174,160, or $256,360 per MLG bogie beam. 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 that 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); 3. Will not affect intrastate aviation in Alaska; and 4.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A330-200 and -300 series airplanes. This AD was prompted 
by a report of a prematurely fractured main landing gear (MLG) bogie 
beam. This AD requires replacing certain MLG bogie beams before 
reaching new reduced life limits. We are issuing this AD to prevent 
fracture of the MLG bogie beam, which, under high speed, could 
ultimately result in the airplane departing the runway, the bogie beam 
detaching from the airplane, or collapse of the MLG; and consequent 
structural damage to the airplane and injury to the occupants.

DATES: This AD becomes effective January 30, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 30, 
2013.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on September 12, 2012 
(77 FR 56172). That NPRM proposed to correct an unsafe condition for 
the specified products. The Mandatory Continuing Airworthiness 
Information (MCAI) states:

    During ground load test cycles on an A340-600 aeroplane, the MLG 
bogie beam has prematurely fractured.
    The results of the investigation identified that this premature 
fracture was due to high tensile standing stress, resulting from dry 
fit axle assembly method. Improvement has been introduced 
subsequently with a grease fit axle assembly method.
    Fatigue and damage tolerance analyses were performed, whose 
results demonstrated that the current life limit of certain MLG 
bogie beams with dry fit axles installed on A330 aeroplanes only 
must be reduced compared to the life limit stated in the A330 
Airworthiness Limitations Section (ALS) Part 1-Safe Life 
Airworthiness Limitation Items revision 05 approved by EASA 
[European Aviation Safety Agency] on 29 July 2010.
    Failure to comply with the reduced life limit of the MLG bogie 
beam with dry fit axle might jeopardize the MLG structural 
integrity.
    For the reasons described above, this [EASA] AD requires the 
replacement of the affected MLG bogie beams before reaching the new 
reduced life limit.

    The unsafe condition is a possible fracture of the MLG bogie beam, 
which, under high speed, could ultimately result in the airplane 
departing the runway, the bogie beam detaching from the airplane, or 
collapse of the MLG; and consequent structural damage to the airplane 
and injury to the occupants. You may obtain further information by 
examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 56172, September 
12, 2012) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 56172, September 12, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 56172, September 12, 2012).

Costs of Compliance

    We estimate that this AD will affect 53 products of U.S. registry. 
We also estimate that it will take about 16 work-hours per MLG bogie 
beam (2 MLG bogie beams per airplane) to comply with the basic 
requirements of this AD. The average labor rate is $85 per work-hour. 
Required parts will cost about $255,000 per MLG bogie beam. 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 this AD to the U.S. operators to be up 
to $27,174,160, or $256,360 per MLG bogie beam.

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 that 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);
    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 AD and placed it in the AD docket.

2. The FAA amends Sec.  39.13 by adding the following new AD:

2012-25-12 Airbus: Amendment 39-17293. Docket No. FAA-2012-0934; 
Directorate Identifier 2011-NM-260-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective January 30, 
2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus Model A330-201, -202, -203, -223, 
-243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 
airplanes, certificated in any category, all manufacturer serial 
numbers (S/Ns).

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    This AD was prompted by a report of a prematurely fractured main 
landing gear (MLG) bogie beam. We are issuing this AD to prevent 
fracture of the MLG bogie beam, which, under high speed, could 
ultimately result in the airplane departing the runway, the bogie 
beam detaching from the airplane, or collapse of the MLG; and 
consequent structural damage to the airplane and injury to the 
occupants.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Bogie Beam Replacement

    At the later of the times specified in paragraph (g)(1) or 
(g)(2) of this AD, replace all MLG bogie beams having part number 
(P/N) 201485300, 201485301, 201272302, 201272304, 201272306, or 
201272307, except those that have S/N S2A, S2B, or S2C, as 
identified in Messier-Dowty Service Letter A33-34 A20, Revision 5, 
including Appendices A through F, dated July 31, 2009, with a new or 
serviceable part, in accordance with a method approved by the 
Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA, or European Aviation Safety Agency (EASA) (or its 
delegated agent).

(h) Parts Installation Limitation

    As of the effective date of this AD, a MLG bogie beam having any 
part number identified in paragraph (g) of this AD, may be installed 
on an airplane, provided its life has not exceeded the life limit
