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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2007-03-18, AD 
2008-17-02, AD 2012-08-03, and AD 2012-15-14, for certain Airbus Model 
A300 B4-2C, B4-103, and B4-203 airplanes; Model A300 B4-600, B4-600R, 
and F4-600R series airplanes, and Model A300 C4-605R Variant F 
airplanes (collectively called Model A300-600 series airplanes); and 
Model A310 series airplanes. AD 2007-03-18, AD 2008-17-02, AD 2012-08-
03, and AD 2012-15-14 required repetitive inspections of the forward 
lugs of the aft bearing at rib 5 of the main landing gear (MLG) on the 
left-hand (LH) and right-hand (RH) wings, and repair if necessary; and 
installation of new bushes with increased interference fit in the 
forward lug of the aft bearing at rib 5 of the MLG on the LH and RH 
wings. This new AD adds airplanes to the applicability; and adds, for 
certain airplanes, repetitive inspections of the MLG rib 5 aft bearing 
forward lugs, and repair if necessary. This AD was prompted by reports 
of cracking in the forward lug of the MLG rib 5 aft bearing attachment. 
We are issuing this AD to detect and correct cracking of the forward 
lugs of the aft bearing at rib 5 of the MLG on the LH and RH wings, 
which could affect the structural integrity of the MLG attachment, 
resulting in possible MLG collapse during landing or rollout.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2008-17-02, Amendment 39-15640 (73 FR 47032, 
August 13, 2008); AD 2012-08-03, Amendment 39-17019 (77 FR 24367, April 
24, 2012); and AD 2012-15-14, Amendment 39-17143 (77 FR 46937, August 
7, 2012). AD 2008-17-02, AD 2012-08-03, and AD 2012-15-14, applied to 
certain Airbus Model A300 B4-2C, B4-103, and B4-203 airplanes; Model 
A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-
605R Variant F airplanes (collectively called Model A300-600 series 
airplanes); and Model A310 series airplanes. The NPRM published in the 
Federal Register on March 12, 2014 (79 FR 13938).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2012-0176, dated September 7, 2012, corrected 
September 20, 2012 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

Several cases of corrosion of the Main Landing Gear (MLG) Rib 5 aft 
fitting forward lug have been reported on A310 family aeroplanes. In 
some instances, corrosion pits caused the cracking of the forward 
lug.

This condition, if not detected and corrected, may lead to the 
complete failure of the fitting and thus could affect the structural 
integrity of the MLG installation.

EASA ADs 2006-0372R1 (http://ad.easa.europa.eu/blob/easa_ad_2006_0372_R1_superseeded.pdf/AD_2006-0372R1_1), 2007-0195 
(http://ad.easa.europa.eu/blob/easa_ad_2007_0195_superseded.pdf/AD_2007-0195_1) [which corresponds with FAA AD 2008-17-02, Amendment 
39-15640 (73 FR 47032, August 13, 2008)], 2010-0250 (http://ad.easa.europa.eu/blob/easa_ad_2010_0250_superseded.pdf/AD_2010-0250_1) [which corresponds with FAA AD 2012-15-14, Amendment 39-
17143 (77 FR 46937, August 7, 2012)] and 2010-0251 (http://ad.easa.europa.eu/blob/easa_ad_2010_0251_superseded.pdf/AD_2010-0251_1) [which corresponds with FAA AD 2012-08-03, Amendment 39-
17019 (77 FR 24367, April 24, 2012)] were issued to address this 
condition and required a repetitive inspection programme of the MLG 
Rib 5 fitting forward lugs and, as terminating action, the 
embodiment of mandatory design change (bushes with increased 
interference fit).

MLG Rib 5 forward lug on A320 family aeroplanes is a similar design 
to the A300/A300-600/A310 family. Since those [EASA] ADs were 
issued, on two A321 aeroplanes, post modification (bushes with 
increased interference fit) MLG Rib 5 forward lugs were reportedly 
found ruptured. One other case was due to a sealant discrepancy that 
led to water ingress and consequently corrosion initiation, leading 
to cracking. Subsequent investigation results have shown that a 
remaining defect, not removed during the repair, had propagated, 
resulting in rupture of the lug.

For the reasons stated above, this new [EASA] AD retains the 
requirements of EASA ADs 2006-0372R1, 2007-0195, 2010-0250 and 2010-
0251, which are superseded, expands the applicability to all models 
and series of A300, A310, A300-600 and A300-600ST aeroplanes, and 
requires:
--For aeroplanes not yet modified or repaired, implementation of 
Modification Service Bulletin (SB) A300-57-0249, A310-57-2090, A300-
57-6106, or A300-57-9019, all at Revision 3, and
--for aeroplanes which already embody that modifications, at 
original issue or revision 01 or 02 of the applicable SB, or have 
MLG Ribs already repaired in accordance with Airbus repair 
instruction R57240221 or R57249121, implementation of an additional 
inspection programme [repetitive detailed inspection for cracking or 
ultrasonic inspections for any crack indication] and associated 
corrective action(s) [detailed inspection for cracking if any crack 
indication found, and repair].

The unsafe condition is cracking of the forward lugs of the aft bearing 
at rib 5 of the MLG on the LH and RH wings, which could affect the 
structural integrity of the MLG attachment, resulting in possible MLG 
collapse during landing or rollout.
    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0142-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 13938, March 12, 2014) and the FAA's response to each comment.

Request To Withdraw the NPRM (79 FR 13938, March 12, 2014)

    United Parcel Service (UPS) requested that we withdraw the NPRM (79 
FR 13938, March 12, 2014) and focus on airplanes that have been 
serviced at the facilities where the two airplanes specified in the 
Discussion section of the NPRM had been reworked. UPS stated that both 
events are the result of an operator not following procedures.
    We disagree with the commenter's request to withdraw the NPRM (79 
FR 13938, March 12, 2014). This issue concerns more than one operator 
and airplane model. We have no data indicating that these events are 
definitively limited to just one repair station or operator. Therefore, 
the unsafe condition may exist on other airplanes of a similar type 
design. Consequently, the actions required by this final rule must be 
done for airplanes identified in paragraph (c) of this AD. We have not 
changed this AD in this regard.

Request To Revise Post-Modification Repetitive Inspection

    UPS requested that we revise the post-modification repetitive 
inspections to a one-time inspection. UPS stated that it does not 
believe that the root cause of the reported events is addressed in the 
NPRM (79 FR 13938, March 12, 2014). UPS explained that the primary 
focus of Airbus Mandatory Service Bulletin A300-57-6106, Revision 03, 
dated January 26, 2012, and the incident investigation is on sealing 
and protection in the bushing head area. UPS stated that the only 
difference between the sealing process of Airbus Mandatory Service 
Bulletin A300-57-6106, Revision 03, dated January 26, 2012, and prior 
service bulletin revision levels, is the application of a single coat 
of polyurethane paint applied over the fillet seal around the bushing 
flange. UPS explained that, based on a process review of Airbus Service 
Bulletin A300-57-6106 and the failure analysis results from the two 
post-modification reported events, it concurs that a post-modification 
check of the modification integrity is valid; however, the post-
modification repetitive inspection should be a one-time inspection to 
verify proper accomplishment of the rework process.
    We disagree with the commenter's request to revise the post-
modification repetitive inspections to a one-time inspection. The 
corresponding MCAI specifies that the inspection be repeated; FAA ADs 
match the MCAI requirements if the MCAI provides an adequate level of 
safety and does not conflict with FAA policies. The sealing process 
could be compromised over time. Thus a repetitive inspection is 
considered necessary to ensure that corrosion will not occur and to 
ensure the structural integrity of the MLG rib 5. However, under the 
provisions of paragraph (aa) of this AD, we might approve requests for 
adjustments to the compliance time if data are submitted to 
substantiate that such an adjustment would provide an acceptable level 
of safety. We have not changed this AD in this regard.

[[Page 7292]]

Request To Supersede AD 2007-03-18, Amendment 39-14929 (72 FR 5919, 
February 8, 2007)

    UPS requested that we revise the wording in paragraph (o) of the 
NPRM (79 FR 13938, March 12, 2014) to terminate the inspections 
required by AD 2007-03-18, Amendment 39-14929 (72 FR 5919, February 8, 
2007); and to add AD 2007-03-18 to the list of superseded ADs in 
paragraph (b)(1) of the NPRM. UPS stated that it believes the intent of 
paragraph (g) of AD 2012-15-14, Amendment 39-17143 (77 FR 46937, August 
7, 2012), was to terminate the AD 2007-03-18 inspection requirements 
upon initiation of inspections as described in Airbus Mandatory Service 
Bulletin A300-57-6107, including Appendix 01, dated August 8, 2007.
    We agree with the commenter's request to add AD 2007-03-18, 
Amendment 39-14929 (72 FR 5919, February 8, 2007), to the list of 
superseded ADs in this final rule. We have revised paragraph (b) of 
this AD by removing paragraph (b)(2) of the NPRM (79 FR 13938, March 
12, 2014); re-designating paragraph (b)(1) of the NPRM as paragraph (b) 
of this AD; adding new paragraph (b)(1) to this AD, which adds AD 2007-
03-18 to the list of superseded ADs in this AD; and re-designating 
paragraphs (b)(1)(i) through (b)(1)(iii) of the NPRM as paragraphs 
(b)(2) through (b)(4) of this AD, respectively.

Request To Remove Repair Approval Requirement

    UPS requested that we remove the statement ``For a repair method to 
be approved, the repair approval must specifically refer to this AD'' 
in paragraph (x) of the NPRM (79 FR 13938, March 12, 2014). UPS 
acknowledged that the rules governing the AD repair and deviation 
approval process for foreign-manufactured aircraft differ from 
domestic-built airplanes. UPS recommended that the FAA meet with U.S. 
operators of foreign-built airplanes to discuss concerns about repair 
instructions being used that might not fully address the unsafe 
condition and to review options to alleviate those concerns.
    We concur with the commenter's request to remove from this final 
rule the requirement that repair approvals must specifically refer to 
this AD. Our responses to specific aspects of this request are 
presented as follows.
    Since late 2006, we have included a standard paragraph titled 
``Airworthy Product'' in all MCAI ADs in which the FAA develops an AD 
based on a foreign authority's AD. The MCAI or referenced service 
information in an FAA AD often directs the owner/operator to contact 
the manufacturer for corrective actions, such as a repair. Briefly, the 
Airworthy Product paragraph allowed owners/operators to use corrective 
actions provided by the manufacturer if those actions were FAA-
approved. In addition, the paragraph stated that any actions approved 
by the State of Design Authority (or its delegated agent) are 
considered to be FAA-approved.
    In the NPRM (79 FR 13938, March 12, 2014), we proposed to prevent 
the use of repairs that were not specifically developed to correct the 
unsafe condition, by requiring that the repair approval provided by the 
State of Design Authority or its delegated agent specifically refer to 
this FAA AD. This change was intended to clarify the method of 
compliance and to provide operators with better visibility of repairs 
that are specifically developed and approved to correct the unsafe 
condition. In addition, we proposed to change the phrase ``its 
delegated agent'' to include ``the Design Approval Holder (DAH) with 
State of Design Authority's design organization approval'' to refer to 
a DAH authorized to approve required repairs for the proposed AD.
    UPS also commented on an NPRM having Directorate Identifier 2012-
NM-101-AD (78 FR 78285, December 26, 2013). UPS stated the following: 
``The proposed wording, being specific to repairs, eliminates the 
interpretation that Airbus messages are acceptable for approving minor 
deviations (corrective actions) needed during accomplishment of an AD 
mandated Airbus service bulletin.''
    This comment has made the FAA aware that some operators have 
misunderstood or misinterpreted the Airworthy Product paragraph to 
allow the owner/operator to use messages provided by the manufacturer 
as approval of deviations during the accomplishment of an AD-mandated 
action. The Airworthy Product paragraph does not approve messages or 
other information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
the approval for an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed that paragraph and 
retitled it ``Contacting the Manufacturer.'' This paragraph now 
clarifies that for any requirement in this AD to obtain corrective 
actions from a manufacturer, the actions must be accomplished using a 
method approved by the FAA, EASA, or Airbus's EASA Design Organization 
Approval (DOA).
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DOA, the approval must include the DOA-authorized 
signature. The DOA signature indicates that the data and information 
contained in the document are EASA-approved, which is also FAA-
approved. Messages and other information provided by the manufacturer 
that do not contain the DOA-authorized signature approval are not EASA-
approved, unless EASA directly approves the manufacturer's message or 
other information.
    This clarification does not remove flexibility afforded previously 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the Airworthiness 
Directive Implementation Aviation Rulemaking Committee to increase 
flexibility in complying with ADs by identifying those actions in 
manufacturers' service instructions that are ``Required for 
Compliance'' with ADs. We continue to work with manufacturers to 
implement this recommendation. But once we determine that an action is 
required, any deviation from the requirement must be approved as an 
alternative method of compliance.
    Other commenters to the NPRM having Directorate Identifier 2012-NM-
101-AD (78 FR 78285, December 26, 2013) pointed out that, in many 
cases, the foreign manufacturer's service bulletin and the foreign 
authority's MCAI may have been issued some time before the FAA AD. 
Therefore, the DOA may have provided U.S. operators with an approved 
repair, developed with full awareness of the unsafe condition, before 
the FAA AD is issued. Under these circumstances, to comply with the FAA 
AD, the operator would be required to go back to the manufacturer's DOA 
and obtain a new approval document, adding time and expense to the 
compliance process with no safety benefit.
    Based on these comments, we removed the requirement that the DAH-
provided repair specifically refer to this

[[Page 7293]]

AD. Before adopting such a requirement, the FAA will coordinate with 
affected DAHs and verify they are prepared to implement means to ensure 
that their repair approvals consider the unsafe condition addressed in 
the AD. Any such requirements will be adopted through the normal AD 
rulemaking process, including notice-and-comment procedures, when 
appropriate.
    We have also decided not to include a generic reference to either 
the ``delegated agent'' or the ``DAH with State of Design Authority 
design organization approval,'' but instead we will provide the 
specific delegation approval granted by the State of Design Authority 
for the DAH.

Change to Paragraph (h)(3) of This AD

    We removed a requirement to use the latest revision of certain 
service information, which appeared as the last sentence at the end of 
paragraph (h)(3) of the NPRM (79 FR 13938, March 12, 2014). That 
requirement already appears in paragraph (h)(2) of this AD.

Conclusion

    We reviewed the available data, including the comments 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 changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 13938, March 12, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 13938, March 12, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service bulletins.
    Airbus Service Bulletin A300-57-0255, including Inspection 
Reporting Form, dated January 13, 2012. The service information 
describes procedures for inspections of the forward lugs of the aft 
bearing at rib 5 of the MLG on the LH and RH wings.
    Airbus Service Bulletin A300-57-6112, including Inspection 
Reporting Form, dated January 13, 2012. The service information 
describes procedures for inspections of the forward lugs of the aft 
bearing at rib 5 of the MLG on the LH and RH wings.
    Airbus Service Bulletin A310-57-2090, Revision 02, dated June 18, 
2010. The service information describes procedures for installation of 
new bushes with increased interference fit in the forward lug of the 
aft bearing at rib 5 of the MLG on the LH and RH wings.
    Airbus Service Bulletin A310-57-2101, including Inspection 
Reporting Form, dated January 13, 2012. The service information 
describes procedures for inspections of the forward lugs of the aft 
bearing at rib 5 of the MLG on the LH and RH wings.
    This service information is reasonably available; see ADDRESSES for 
ways to access this service information.

Costs of Compliance

    We estimate that this AD affects 194 airplanes of U.S. registry.
    The actions that are required by AD 2008-17-02, Amendment 39-15640 
(73 FR 47032, August 13, 2008), and retained in this AD take about 5 
work-hours per product, at an average labor rate of $85 per work-hour. 
Based on these figures, the estimated cost of the actions that were 
required by AD 2008-17-02 is $425 per product.
    The actions that are required by AD 2012-08-03, Amendment 39-17019 
(77 FR 24367, April 24, 2012), and retained in this AD take about 38 
work-hours per product, at an average labor rate of $85 per work-hour. 
Required parts cost about $4,590 per product. Based on these figures, 
the estimated cost of the actions that were required by AD 2012-08-03 
is $7,820 per product.
    The actions that are required by AD 2012-15-14, Amendment 39-17143 
(77 FR 46937, August 7, 2012), and retained in this AD take about 3 
work-hours per product, at an average labor rate of $85 per work-hour. 
Based on these figures, the estimated cost of the actions that were 
required by AD 2012-15-14 is $255 per product.
    We also estimate that it would take about 3 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 $49,470, or $255 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD. We 
have no way of determining the number of products that may need these 
actions.
    According to the manufacturer, some of the costs of 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.

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);

[[Page 7294]]

    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
