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.
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 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 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);
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.
