Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2009-15-17 for 
certain Airbus Model A330-200 and -300 series airplanes; and Model 
A340-200 and -300 series airplanes. AD 2009-15-17 required an 
inspection for damage to the protective treatments or any corrosion of 
all main landing gear (MLG) bogie beams, and application of protective 
treatments if no damage or corrosion was found. If any damage or 
corrosion was found, corrective action followed by the application of 
protective treatments was required. This new AD continues to require 
inspections for damage to the protective treatments or any corrosion of 
all MLG bogie beams, application of protective treatments, and 
corrective action if necessary. This new AD also requires modification 
of the MLG bogie beams, which terminates the repetitive inspections for 
any modified bogie beam. This new AD allows optional methods of 
compliance for certain actions, and adds Airbus Model A330-200 
Freighter series airplanes to the applicability. This new AD revises 
the compliance times and adds a one-time inspection for airplanes that 
were inspected too early. This AD was prompted by reports of thin paint 
coats and paint degradation on enhanced main landing gear (MLG) bogie 
beams, as well as reports that some airplanes have been inspected too 
early and not re-inspected as needed. We are issuing this AD to detect 
and correct damage or corrosion of the MLG bogie beams, which could 
cause a runway excursion event, bogie beam detachment from the 
airplane, or MLG collapse, and could result in damage to the airplane 
and injury to the occupants.

DATES: This AD is effective November 2, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 2, 
2016.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a second supplemental notice of proposed rulemaking 
(SNPRM) to amend 14 CFR part 39 to supersede AD 2009-15-17, Amendment 
39-15980 (74 FR 37523, July 29, 2009) (``AD 2009-15-17''). AD 2009-15-
17 applied to certain Airbus Model A330-200 and -300 series airplanes, 
and Model A340-200 and -300 series airplanes. The second SNPRM 
published in the Federal Register on February 5, 2016 (81 FR 6185) 
(``the second SNPRM''). We preceded the second SNPRM with the first 
SNPRM, which was published in the Federal Register on March 5, 2014 (79 
FR 12414) (``the first SNPRM''). We preceded the first SNPRM with a 
notice of proposed rulemaking (NPRM) that published in the Federal 
Register on September 25, 2013 (78 FR 58978) (``the NPRM''). The NPRM 
was prompted by reports of thin paint coats and paint degradation on 
enhanced MLG bogie beams. The NPRM proposed to continue to require 
inspections for damage to the protective treatments or any corrosion of 
all MLG bogie beams, application of protective treatments, and 
corrective action if necessary. The NPRM also proposed to require 
modification of the MLG bogie beams, which would terminate the 
repetitive inspections for any modified bogie beam. In addition, the 
NPRM proposed to allow optional methods of compliance for certain 
actions, and to add Airbus Model A330-200 Freighter series airplanes to 
the applicability. The first SNPRM proposed to revise the compliance 
times and add a one-time inspection for airplanes that were inspected 
too early. The second SNPRM proposed to clarify the required actions 
and the specific configurations to which the actions must be applied. 
We are issuing this AD to detect and correct damage or corrosion of the 
MLG bogie beams, which could cause a runway excursion event, bogie beam 
detachment from the airplane, or MLG collapse, and could result in 
damage to the airplane and injury to the occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2013-0267R1, dated March 4, 2014; corrected May 8, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A330-200 Freighter, -200, and -300 series airplanes; and Model A340-200 
and -300 series airplanes. The MCAI states:

    The operator of an A330 aeroplane (which has a common bogie beam 
with the A340) reported a fracture of the Right Hand (RH) main 
landing gear (MLG) bogie beam, which occurred while turning during 
low speed taxi maneuvers. The bogie fractured aft of the pivot point 
and remained attached to the sliding tube by the brake torque 
reaction rods. After this RH bogie failure, the aeroplane continued 
for approximately 40 meters on the forks of the sliding member 
before coming to rest on the taxiway.
    The investigations revealed that this event was due to corrosion 
pitting occurring on the bore of the bogie beam.
    This condition, if not detected and corrected, could lead to a 
runway excursion event or to detachment of the bogie from the 
aeroplane, or to MLG collapse, possibly resulting in damage to the 
aeroplane and injury to the occupants.
    To enable early detection and repair of corrosion of the 
internal surfaces, EASA issued EASA AD 2007-0314 to require a one-
time inspection of all MLG bogie beams, except Enhanced MLG bogie 
beams, and the reporting of the results to Airbus. EASA AD 2007-0314 
was revised and later superseded by EASA AD 2008-0093, reducing the 
inspection threshold period.
    The results of subsequent investigations showed thin paint coats 
and paint degradation, confirmed as well on Enhanced MLG bogie 
beams. To address this additional concern, EASA issued AD 2011-0141 
[which was not mandated by the FAA], retaining the requirements of 
EASA AD 2008-0093, which was superseded, to require a one-time 
visual inspection of all MLG bogie beams, including a visual 
examination of the internal diameter for corrosion or damage to 
protective treatments of the bogie beam and measurement of the paint 
thickness on the internal bore, accomplishment of the applicable 
corrective actions and a modification of the MLG bogie beam to 
improve the coat paint application method, and application of 
corrosion protection.
    Prompted by in-service requests, EASA issued EASA AD 2012-0015 
retaining the requirements of EASA AD 2011-0141, which was 
superseded, and introducing repetitive inspections of the MLG bogie 
beams, which allows extension of the compliance time for the MLG 
bogie beam modification from 15 years to 21 years. Modification of a 
MLG bogie beam constitutes terminating action for the repetitive 
inspections for that MLG bogie beam.
    Reports on inspection results provided to Airbus show that some 
aeroplanes were initially inspected too early (before 4 years and 6 
months since aeroplane first flight with bogie beam installed/
installed after overhaul) and have not been re-inspected as 
required.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2012-0015, which is superseded, and 
redefines the inspection periodicity. This [EASA] AD also introduces 
a specific one-time inspection for aeroplanes that have been 
inspected too early.
    Prompted by operator comments, this [EASA] AD is revised to 
clarify the required actions and the specific configurations to 
which the actions must be applied. Appendix 1 of this [EASA] AD has 
been amended accordingly.
    This [EASA] AD is republished to editorially correct paragraph 
(4).

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2013-
0828.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the second 
SNPRM and the FAA's response.

Request To Revise the Applicability of the Second SNPRM

    American Airlines (AAL) requested that we revise the applicability 
of the proposed AD (in the second SNPRM) to exclude airplanes with MLG 
bogie beams that have had Airbus modification 58896 embodied in-
service, as specified in Airbus Service Bulletin A330-32-3237. AAL 
pointed out that paragraph (c) of the proposed AD (in the second SNPRM) 
does not reflect MLG bogie beams that were modified in-service.
    We disagree with the request to revise the applicability of the 
proposed AD (in the second SNPRM). Paragraph (k) of this AD 
specifically requires inspection, repair, modification, and re-
identification of the MLG bogie beams. However, paragraph (f) of this 
AD states that actions already done need not be repeated. If an 
operator has already accomplished the actions required by paragraph (k) 
of this AD before the effective date of this AD, then the modified 
airplane is already in compliance with the corresponding requirements 
of this AD. We have not made any changes to this AD in this regard.

Additional Changes Made in This AD

    We have revised paragraph (m)(1) of this AD to remove reference to 
paragraph (g) of this AD; the reporting requirement specified in 
paragraph (m)(1) of this AD is required only for the

[[Page 66520]]

inspection required by paragraph (k) of this AD.
    We have also revised paragraph (m)(2) of this AD to reference the 
correct service information for reporting inspection findings for the 
inspection required by paragraph (h) of this AD.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
second SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the second SNPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information.
     Airbus Service Bulletin A330-32-3225, Revision 02, 
including Appendix 1, dated October 26, 2012. This service information 
describes procedures for cleaning the internal bore and accomplishing a

and corrosion of the internal bores of the LH and RH MLG bogie beam and 
repair, as well as modification and re-identification.
     Airbus Service Bulletin A340-32-4268, Revision 03, 
including Appendix 1, dated January 14, 2013. This service information 
describes procedures for cleaning the internal bore and accomplishing a 
detailed inspection of internal surfaces of the LH and RH MLG bogie 
beams to detect any damage to the protective treatments and any 
corrosion, and measuring the paint thickness on the internal bore.
     Airbus Service Bulletin A340-32-4279, Revision 01, 
including Reporting Sheet, dated October 14, 2011. This service 
information describes procedures for a detailed inspection for damage 
and corrosion of the internal bores of the LH and RH MLG bogie beam, 
repair, modification, and reidentification.
    Messier-Bugatti-Dowty has issued the following service information.
     Messier-Dowty Service Bulletin A33/34-32-278, Revision 1, 
including Appendixes A and B, dated August 24, 2011. This service 
information describes procedures for inspections for damage and 
corrosion to the protective treatment of the internal bores of the LH 
and RH MLG bogie beam, and repairs.
     Messier-Dowty Service Bulletin A33/34-32-283, Revision 1, 
including Appendix A, dated July 10, 2012. This service information 
describes procedures for modification of the LH and RH MLG bogie beams.
     Messier-Dowty Service Bulletin A33/34-32-284, Revision 1, 
including Appendix A, dated July 10, 2012. This service information 
describes procedures for modification of the LH and RH MLG bogie beams.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 51 airplanes of U.S. registry.
    We also estimate that it takes about 34 work-hours per product to 
comply with this AD, and 1 work-hour per product for reporting. The 
average labor rate is $85 per work-hour. Based on these figures, we 
estimate the cost of this AD on U.S. operators to be $151,725, or 
$2,975 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 10 work-hours at a labor rate of $85 per work-hour, for a 
cost of $850 per product. We have no way of determining the number of 
aircraft that might need these actions.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2009-15-17, Amendment 39-15980 (74 FR 37523, July 29, 2009), and adding 
the following new AD:

2016-18-07 Airbus: Amendment 39-18637; Docket No. FAA-2013-0828; 
Directorate Identifier 2012-NM-036-AD.

(a) Effective Date

    This AD is effective November 2, 2016.

(b) Affected ADs

    This AD replaces AD 2009-15-17, Amendment 39-15980 (74 FR 37523, 
July 29, 2009) (``AD 2009-15-17'').

(c) Applicability

    This AD applies to the airplanes identified in paragraphs (c)(1) 
and (c)(2) of this AD, certificated in any category, all 
manufacturer serial numbers (MSN), except those on which Airbus 
modification 58896 has been embodied in production.
    (1) Airbus Model A330-223F, -243F, -201, -202, -203, -223, -243, 
-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.
    (2) Airbus Model A340-211, -212, -213, -311, -312, and -313 
airplanes.

(d) Subject

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

(e) Reason

    This AD was prompted by reports of thin paint coats and paint 
degradation on enhanced main landing gear (MLG) bogie beams, as well 
as reports that some airplanes have been inspected too early and not 
re-inspected as needed. We are issuing this AD to detect and correct 
damage or corrosion of the MLG bogie beams, which could cause a 
runway excursion event, bogie beam detachment from the airplane, or 
MLG collapse, and could result in damage to the airplane and injury 
to the occupants.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Inspections for Certain Airplane Configurations

    For airplanes equipped with basic MLG (201252 series), or growth 
MLG (201490 series): After 54 months at the earliest, but no later 
than 72 months since the left-hand (LH) or right-hand (RH) MLG bogie 
beam's first flight on an airplane, or since its first flight on an 
airplane after overhaul, as applicable, clean the internal bore and 
accomplish a detailed inspection of internal surfaces of the LH and 
RH MLG bogie beams to detect any damage to the protective treatments 
and any corrosion, and measure the paint thickness on the internal 
bore, in accordance with the Accomplishment Instructions of Airbus 
Service Bulletin A330-32-3225, Revision 02, including Appendix 1, 
dated October 26, 2012; or Airbus Service Bulletin A340-32-4268, 
Revision 03, including Appendix 1, dated January 14, 2013; as 
applicable. Repeat the inspections thereafter at intervals not less 
than 54 months, but not exceeding 72 months, after the most recent 
inspection. During overhaul of a MLG bogie beam, any corrosion will 
be removed, which means that the first inspection after overhaul of 
that MLG bogie beam, as required by this paragraph, is between 54 
months and 72 months since its first flight on an airplane after 
overhaul.

(h) One-Time Detailed Inspection for Certain Airplane Configurations

    For airplanes equipped with basic MLG (201252 series), or growth 
MLG (201490 series) having a LH or RH MLG bogie beam that has 
already exceeded 72 months since its first flight on an airplane, or 
since its first flight on an airplane after overhaul, as applicable, 
as of the effective date of this AD; and that has been inspected as 
specified in Airbus Service Bulletin A330-32-3225 or Airbus Service 
Bulletin A340-32-4268, as applicable, earlier than 54 months since 
first flight of the affected MLG bogie beam on an airplane, or since 
its first flight on an airplane after its most recent overhaul, as 
applicable: Within the applicable compliance time indicated in 
paragraphs (h)(1) through (h)(4) of this AD, clean the internal bore 
and accomplish a detailed inspection of the internal surfaces of the 
LH and RH MLG bogie beams to detect any damage to the protective 
treatments and any corrosion, and measure the paint thickness on the 
internal bore, in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A330-32-3225, Revision 02, including 
Appendix 1, dated October 26, 2012; or Airbus Service Bulletin A340-
32-4268, Revision 03, including Appendix 1, dated January 14, 2013; 
as applicable.
