Final rule.

# SUMMARY:

We are superseding Airworthiness Directive (AD) 2000-12-12, for certain Airbus Model A300, A300-600, and A310 series airplanes. AD 2000-12-12 required inspecting to detect cracks in the lower spar axis of the nacelle pylon between ribs 9 and 10, and repair if necessary. AD 2000-12-12 also provided for optional modification of the pylon, which terminated the inspections for Model A300 series airplanes. This new AD reduces the initial and repetitive inspection compliance times. This AD was prompted by reports of cracking of the lower pylon spar after accomplishing the existing modification. We are issuing this AD to detect and correct fatigue cracking, which could result in reduced structural integrity of the lower spar of the nacelle pylon.

## Discussion

                    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2000-12-12, Amendment 39-11790 (65 FR 39072, June 23, 2000). AD 2000-12-12 applied to certain Airbus Model A300, A300-600, and A310 series airplanes. The NPRM published in the                     **Federal Register**                     on December 30, 2013 (78 FR 79333).                

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013-0016, dated September 17, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Model A300, A300-600, and A310 series airplanes. The MCAI states:

Cracks were found between ribs 9 and 10 in the lower pylon spar of A310 aeroplanes equipped with Pratt & Whitney (PW) engines.

For A310, A300 and A300-600 aeroplanes and, in order to prevent crack initiation, the implementation of a first inspection programme of this area was required by DGAC [Direction Générale de l'Aviation Civile] France AD 1992-049-130(B) [which corresponds to certain actions in FAA AD 2000-12-12, Amendment 39-11790 (65 FR 39072, June 23, 2000)], currently at Revision 4.

General Electric (GE) and PW pylons on A300 aeroplanes are also affected, due to similar design.

                        After that [DGAC] AD was issued, prompted by new findings, a specific inspection programme for A310 aeroplanes was introduced and required by DGAC France AD 1999-237-285(B) [which corresponds to certain actions in FAA AD 2000-12-12, Amendment 39-11790 (65 FR 39072, June 23, 2000)], which was subsequently superseded by EASA AD 2008-0008 [                        *http://ad.easa.europa.eu/​blob/​easa_​ad_​2008_​0008_​superseded.pdf/​AD_​2008-0008_​1*], which introduced new thresholds and intervals in the frame of the A310 extended service goal exercise.                    

Some cracks, which were discovered after the implementation of the preventive modification, prompted Airbus to perform a new Fatigue and Damage Tolerance analysis with a refined model of the area with and without repair or preventive reinforcement before crack appearance. Based on the results of this analysis, Airbus revised the related Service Bulletins to introduce more restrictive thresholds and intervals for curative and preventive repair configuration.

                        EASA issued AD 2013-0014 [                        *http://ad.easa.europa.eu/​blob/​easa_​ad_​2013_​0214.pdf/​AD_​2013-0014_​1*], which superseded DGAC France AD 1992-049-130(B) and EASA AD 2008-0008, to mandate a new inspection programme [including related investigative and corrective actions].                    

After EASA AD 2013-0014 was issued, further analysis allowed to identify one A300 aeroplane model and one retrofitted A300 MSN [manufacturer serial number] missing in the applicability chapter.

For the reason described above, this [EASA] AD retains the requirements of EASA AD 2013-0014, which is superseded, and clarifies the Applicability section and adds one A300 model and one A300 MSN.

                    The unsafe condition is fatigue cracking, which could result in reduced structural integrity of the lower spar of the nacelle pylon. Related investigative actions include additional eddy current and liquid penetrant inspections for cracking. Corrective actions include repairing cracking. For certain cracking lengths, repairs are described as reinforcing the lower spar with a doubler. You may examine the MCAI in the AD docket on the Internet at                     *http://www.regulations.gov/​#!documentDetail;​D=​FAA-2013-1066-0002*.                

## Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (78 FR 79333, December 30, 2013) and the FAA's response to each comment.

## “Contacting the Manufacturer” Paragraph in This AD

                    United Parcel Service (UPS) requested that we revise the NPRM (78 FR 79333, December 30, 2013) to remove the requirement to include the AD reference in repair approvals. UPS noted its concerns that the proposal would require development of a unique Airbus process for U.S. operators; that it could have significant financial and administrative impacts to existing customer support agreements and different AD records requirements within an operator's fleet; that it will increase requests for approval of alternative methods of compliance                           ( print page 72128)                        (AMOC) and result in delayed return to service; and that it creates a new requirement that did not exist when the superseded AD was written.                

We concur with the commenter's request to remove from this AD the requirement that repair approvals must specifically refer to this AD.

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 (78 FR 79333, December 30, 2013), 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 a design approval holder (DAH) with State of Design Authority design organization approval (DOA), as applicable, to refer to a DAH authorized to approve required repairs for the proposed AD.

UPS specifically stated the following in its comments to the NPRM (78 FR 79333, December 30, 2013): “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 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.

Commenters to an 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 from this AD 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 also have decided to revise the language in paragraphs (g)(3), (g)(4), (h)(3), (h)(4), (i)(3), and (i)(4) of this AD to retain references to repair approvals done by the DGAC (or its delegated agent) from AD 2000-12-12, Amendment 39-11790 (65 FR 39072, June 23, 2000), as well as including references to EASA and the specific delegation approval granted by EASA for the DAH. Further, we revised paragraphs (n)(2) and (n)(3) of this AD to remove references to the “delegated agent” and the “DAH with State of Design Authority design organization approval” and instead provided the specific delegation approval granted by the State of Design Authority for the DAH.

## Conclusion

We reviewed the relevant 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 minor changes:
    - Are consistent with the intent that was proposed in the NPRM ( 78 FR 79333 , December 30, 2013) for correcting the unsafe condition; and
    - Do not add any additional burden upon the public than was already proposed in the NPRM ( 78 FR 79333 , December 30, 2013).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

## Costs of Compliance

We estimate that this AD affects 91 airplanes of U.S. registry.

                    The actions required by AD 2000-12-12, Amendment 39-11790 (65 FR 39072, June 23, 2000), and retained in                           ( print page 72129)                        this AD take about 4 work-hours per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions required by AD 2000-12-12 is $340 per product.                

We also estimate that it would take about 12 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 $92,820, or $1,020 per product.

In addition, we estimate that any necessary follow-on actions would take about 60 work-hours and require parts costing $1,680, for a cost of $6,780 per product. We have no way of determining the number of aircraft that might need these actions.

## 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.
