Federal Register Volume 82, Issue 128 (July 6, 2017)

We are superseding Airworthiness Directive (AD) 2013-10-03, which applied to all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. AD 2013-10-03 required one-time inspections for deformation and damage of the bogie beams of the main landing gear (MLG); repetitive inspections for damage and corrosion of the sliding piston sub-assembly on certain airplanes; and related investigative and corrective actions if necessary. This new AD removes Model A340-500 and 600 series airplanes from the applicability; removes certain one-time inspections of the MLG bogie beams and the sliding piston sub-assembly; revises certain compliance times; and requires replacement of certain MLGs with MLGs having an improved bogie beam, which constitutes terminating action for the repetitive inspections on the modified MLG. This AD was prompted by reports of corroded and cracked bogie beams under the bogie stop pad. We are issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2013-10-03, 
which applied to all Airbus Model A330-200, -200 Freighter, and -300 
series airplanes; and Model A340-200, -300, -500, and -600 series 
airplanes. AD 2013-10-03 required one-time inspections for deformation 
and damage of the bogie beams of the main landing gear (MLG); 
repetitive inspections for damage and corrosion of the sliding piston 
sub-assembly on certain airplanes; and related investigative and 
corrective actions if necessary. This new AD removes Model A340-500 and 
600 series airplanes from the applicability; removes certain one-time 
inspections of the MLG bogie beams and the sliding piston sub-assembly; 
revises certain compliance times; and requires replacement of certain 
MLGs with MLGs having an improved bogie beam, which constitutes 
terminating action for the repetitive inspections on the modified MLG. 
This AD was prompted by reports of corroded and cracked bogie beams 
under the bogie stop pad. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective August 10, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 10, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2013-10-03, Amendment 39-17456 (78 
FR 31386, May 24, 2013) (``AD 2013-10-03''). AD 2013-10-03 applied to 
all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; 
and Model A340-200, -300, -500, and -600 series airplanes. The SNPRM 
published in the Federal Register on March 22, 2017 (82 FR 14642) 
(``the SNPRM''). We preceded the SNPRM with a notice of proposed 
rulemaking (NPRM) that published in the Federal Register on March 1, 
2016 (81 FR 10540) (``the NPRM''). The NPRM was prompted by reports of 
corroded and cracked bogie beams under the bogie stop pad. The NPRM 
proposed to remove Model A340-500, and -600 series airplanes from the 
applicability, remove certain one-time inspections of the MLG bogie 
beams and the sliding piston sub-assembly; revise certain compliance 
times and provide, for certain airplanes, an optional terminating 
action for the repetitive actions. The SNPRM proposed to require 
replacement of a MLG having part number (P/N) 201252 series and P/N 
201490 series with a MLG that has an improved bogie beam, which would 
constitute terminating action for the repetitive inspections on the 
modified MLG. We are issuing this AD to detect and correct damage or 
corrosion under the bogie stop pad of both MLG bogie beams; this 
condition could result in a damaged bogie beam and consequent 
detachment of the beam from the airplane, collapse of the MLG, or 
departure of the airplane from the runway, possibly resulting in damage 
to the airplane and injury to occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0108, dated June 8, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Airbus Model A330-200, -200 Freighter, and 
-300 series airplanes; and Model A340-200 and -300 series airplanes. 
The MCAI states:

    During a scheduled maintenance inspection on the Main Landing 
Gear (MLG), the bogie stop pad was found deformed and cracked. Upon 
removal of the bogie stop pad for replacement, the bogie beam was 
also found cracked. The results of a laboratory investigation 
indicated that an overload event had occurred and no fatigue 
propagation of the crack was evident. A second bogie beam crack was 
subsequently found on another aeroplane, located under a bogie stop 
pad which only had superficial paint damage.
    This condition, if not detected and corrected, could lead to 
landing gear bogie detachment from the aeroplane, or landing gear 
collapse, or a runway excursion, possibly resulting in damage to the 
aeroplane and injury to the occupants and/or people on the ground.
    To address this potential unsafe condition, EASA issued AD 2008-
0223 [which corresponds to FAA AD 2010-02-10, Amendment 39-16181 (75 
FR 4477, January 28, 2010)] to require accomplishment of a one-time 
detailed inspection under the bogie stop pad of both MLG bogie 
beams. As a result of the one-time inspection required by that 
[EASA] AD, numerous bogie stop pad were found corroded and a few 
cracked. The one-time inspection was retained in EASA AD 2011-0211 
[which corresponds to FAA AD 2013-10-03], which superseded EASA AD 
2008-0223, which also introduced repetitive inspections, except for 
A340-500/-600 aeroplanes.
    After EASA AD 2011-0211 was issued, further investigation led to 
the conclusion that the one-time inspection was no longer necessary 
and only the repetitive inspections should remain. In addition, it 
was determined that repetitive inspections were also necessary for 
MLG on A340-500/-600 aeroplanes.
    Prompted by these conclusions, EASA issued AD 2014-0120, 
partially retaining the requirements of EASA AD 2011-0211, which was 
superseded, and introducing repetitive detailed inspections of the 
MLG on A340-500 and A340-600 aeroplanes. Subsequently, further 
analysis indicated that repetitive inspections of the MLG on A340-
500/-600 aeroplanes were not necessary after all. In addition, the 
threshold for the inspection of MLG P/N 10-210 series was raised 
from 24 to 126 months, and Airbus developed a modification of the 
MLG P/N 10-210 series which provides an (optional) terminating 
action for the repetitive inspections.
    Consequently, EASA AD 2014-0120 was revised to delete the 
requirements for A340-500/-600 aeroplanes, to amend the inspection 
threshold for MLG P/N 10-210 series, and to introduce an optional 
terminating action for aeroplanes with MLG P/N 10-210 series.
    Since EASA AD 2014-0120R1 was issued, Airbus developed a 
modification (mod 205289) of the MLG P/N 201252 series and P/N 
201490 series that must be embodied in service with Airbus SB A330-
32-3275 or SB A340-32-4305. It was also identified that A340-500/-
600 aeroplanes could be removed from the applicability of this 
[EASA] AD as no more actions were required on these aeroplanes.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0120R1, which is superseded, removes 
the A340-500/-600 aeroplanes from the Applicability and requires the 
modification of the MLG P/N 201252 series and P/N 201490 series, 
which constitutes terminating action for the repetitive inspections 
required by this [EASA] AD.

The required actions include repetitive detailed inspections for damage 
and corrosion of the sliding piston sub-assembly, and related 
investigative and corrective actions if necessary. Related 
investigative actions include a test for indications of corrosion and 
damage to the bogie assembly base material, and a magnetic particle 
inspection for cracks, corrosion, and damage of the bogie beam. 
Corrective actions include repairing affected parts.
    The required terminating action (for a MLG having P/N 201252 series 
or P/N 201490 series) and the optional terminating action (for a MLG 
having P/N 10-210 series) are modifications of the bogie beam of a MLG, 
which consist of installing a nickel under chrome

coating, a new bogie beam stop pad, and new stop pad brackets.

3984.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. Air Line Pilots 
Association, International supported the SNPRM.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting 
this 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 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information.

Costs of Compliance

    We estimate that this AD affects 89 Model A330-200, -200 Freighter, 
and -300 series airplanes of U.S. registry.
    We estimate that it will take about 13 work-hours per product to 
comply with the basic requirements of this AD. 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 $98,345, or $1,105 per product.
    Currently, there are no Model A340-200 or -300 series airplanes on 
the U.S. Register. However, if an affected airplane is imported and 
placed on the U.S. Register in the future, it would be subject to the 
same per-airplane cost specified above for the Model A330-200, -200 
Freighter, and -300 series airplanes.
    In addition, we estimate that any necessary follow-on actions will 
take about 24 work-hours and require parts costing $78, for a cost of 
$2,118 per product. We have no way of determining the number of 
aircraft that might need these actions.
    According to the manufacturer, all of the parts costs of the 
optional terminating action specified in this AD may be covered under 
warranty, thereby reducing the cost impact on affected individuals. We 
do not control warranty coverage for affected individuals. As a result, 
we have included all costs in our cost estimate. We have received no 
definitive data that would enable us to provide the work-hour cost 
estimates for the optional terminating action specified in 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 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.

(p) Other FAA AD Provisions

    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 approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the manager of the International Branch, send it to the 
attention of the person identified in paragraph (q)(2) of this AD. 
Information may be emailed to: [email protected].
    (i) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (ii) AMOCs approved previously for AD 2013-10-03 are not 
approved as AMOCs with this AD.
    (2) Contacting the Manufacturer: As of the effective date of 
this AD, for any requirement in this AD to obtain corrective actions 
from a manufacturer, the action must be accomplished using a method 
approved by the Manager, International Branch, ANM-116, Transport

that are not identified as RC are recommended. Those procedures and 
tests that are not identified as RC may be deviated from using 
accepted methods in accordance with the operator's maintenance or 
inspection program without obtaining approval of an AMOC, provided 
the procedures and tests identified as RC can be done and the 
airplane can be put back in an airworthy condition. Any 
substitutions or changes to procedures or tests identified as RC 
require approval of an AMOC.
