AD 2017-06-07

We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports that nonconforming aluminum alloy was used to manufacture several structural parts on the inboard flap. This AD requires identification of the potentially affected inboard flap parts, a one-time eddy current inspection to identify which material the parts are made of, and, depending on findings, replacement with serviceable parts. We are issuing this AD to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):

2017-06-07 Airbus: Amendment 39-18831; Docket No. FAA-2016-8851; Directorate Identifier 2016-NM-070-AD.

(a) Effective Date

This AD is effective May 15, 2017.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Airbus Model A330-223F and -243F airplanes; A330-201, -202, -203, -223, and -243 airplanes; A330-301, -302, - 303, -321, -322, -323, -341, -342, and -343 airplanes; A340-211, - 212, and -213 airplanes; A340-311, -312, and -313 airplanes; A340- 541 airplanes; and A340-642 airplanes; certificated in any category, all manufacturer serial numbers.

(d) Subject

Air Transport Association (ATA) of America Code 57, Wings.

(e) Reason

This AD was prompted by reports that nonconforming aluminum alloy was used to manufacture several structural parts on the inboard flap. We are issuing this AD to detect and correct structural parts of inboard flaps made of nonconforming aluminum alloy, which could result in reduced structural integrity of the airplane.

(f) Compliance

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

(g) Inboard Flap Serial Number Identification

Within 24 months after the effective date of this AD: Inspect each left-hand (LH) and right-hand (RH) inboard flap, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-57-3120, dated September 18, 2015; or Airbus Service Bulletin A340-57-5036, dated September 18, 2015; as applicable; to identify the serial number. A review of airplane deliveryand maintenance records is acceptable in lieu of inspecting the inboard flaps, provided those records can be relied upon for that purpose and the serial number of the affected parts can be conclusively identified from that review. The serial numbers of affected inboard flaps are identified in figure 1 to paragraphs (g), (j)(1), and (j)(2) of this AD.

Note 1 to paragraphs (g) and (h) of this AD: Airbus Service Bulletin A330-57-3120, dated September 18, 2015; and Airbus Service Bulletin A340-57-5036, dated September 18, 2015; list the serial numbers of potentially affected LH and RH inboard flaps and the corresponding airplane serial number on which these parts were installed during production. The airplane serial number list is for information only, as it cannot be excluded that a potentially affected inboard flap has been removed from an airplane and later re-installed on another airplane.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-500 and -600 series airplanes. The NPRM published in the Federal Register on August 31, 2016 (81 FR 59922) (``the NPRM''). The NPRM was prompted by reports that nonconforming aluminum alloy was used to manufacture several structural parts on the inboard flap. The NPRM proposed to require identification of the potentially affected inboard flap parts, a one-time eddy current inspection to identify which material the parts are made of, and, depending on findings, replacement with serviceable parts. We are issuing this AD to detect and correct structural parts of inboard flaps made of nonconforming aluminum alloy, which could result in reduced structural integrity of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016-0231, dated November 22, 2016 (``EASA AD 2016-0231'') (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), which superseded EASA Airworthiness Directive 2016-0082, dated April 27, 2016 (``EASA AD 2016-0082''), to correct an unsafe condition all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-200, -300, -500 and -600 series airplanes. The MCAI states:

Following an Airbus quality control review on the final assembly line, it was discovered that non-conforming aluminium alloy was used to manufacture several structural parts on the inboard flap.
This condition, if not detected and corrected, could reduce the structural integrity of the aeroplane.
To address this potential unsafe condition, Airbus issued Service Bulletin (SB) A330-57-3120 and SB A340-57-5036 to provide instructions to identify and inspect the potentially affected parts.
Consequently, EASA issued AD 2016-0082 to require identification of the potentially affected inboard flap parts, a one-time special detailed inspection (SDI) [eddy current measurement] to identify which material they are made of and, depending on findings, replacement with serviceable parts.
Since EASA AD 2016-0082 was issued, it was confirmed that flaps, initially installed on A340-500 and A340-600 aeroplanes, may also have been installed in service on A340-200 or A340-300 aeroplanes. As this installation was not done during production, no SB was published for these models.
For the reason described above, this [EASA] AD retains the requirements of EASA AD 2016-0082 [which corresponded to the FAA NPRM], which is superseded, expands the Applicability to include A340-200 and A340-300 aeroplanes, corrects a typographical error in Appendix 1 of this [EASA] AD for one affected flap, Right Hand (RH) serial number (s/n) ``TB 11411'' in placeof ``TB 14411'' (date of first operation: 19/04/13) and identified in bold in Appendix 1, and adds the prefix ``TB'' to the s/n's of all Left Hand (LH) and RH flaps, which was inadvertently omitted in Appendix 1 of [EASA] AD 2016-0082. This [EASA] AD also allows, under certain conditions, installation of an affected inboard flap on an aeroplane.

Airbus Model A340-200 and -300 series airplanes have been added to the applicability of this AD. Since there are currently no domestic operators of these added airplanes, notice and opportunity for public comment before issuing this AD are unnecessary.
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-2016- 8851.

Comments

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

Request To Account for a Superseding EASA Airworthiness Directive

Airbus commented that EASA was planning to supersede EASA AD 2016- 0082 with EASA AD 2016-0231, which would update the AD applicability, correct a certain part serial number, and add the prefix ``TB'' to the serial

[[Page 17108]]

numbers of all flaps. (These changes are described in the MCAI.)
We agree with the commenter and have revised this AD to update the applicability, correct a serial number for a right-hand flap (from TB14411 to TB11411), and add the prefix ``TB'' before each flap serial number.

Requests To Extend Compliance Time for Part Replacement

Airbus and American Airlines requested that the requirement to replace an affected part within 30 days after performing the eddy current inspection be changed to allow a longer compliance time. Paragraph (i) of the proposed AD states that if a part requires replacement due to a nonconforming material finding per paragraph (h) of the proposed AD, the part must be replaced within 30 days after the finding in accordance with a method approved by the FAA, EASA, or Airbus's EASA Design Organization Approval (DOA). EASA AD 2016-0082, paragraph (3), states, for the same nonconforming material finding, to contact Airbus within 30 days of the finding for approved replacement instructions, and within the compliance time(s) specified in those instructions to replace the nonconforming parts accordingly. The commenters stated that this allows more flexibility for replacement actions.
We agree that additional time can be allowed for replacement of affected parts if approved by the Manager, International Branch, ANM- 116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA). We have revised paragraph (i) of this AD accordingly. This provision corresponds to EASA AD 2016-0231, which superseded EASA AD 2016-0082.

Removal of Note From Regulatory Text

We have removed Note 2 to paragraph (h)of the proposed AD, and added text to paragraph (h) of this AD to clarify that the date of the first operation of the flap is specified in figure 1 to paragraphs (g), (j)(1), and (j)(2) of this AD.

Conclusion

We reviewed the relevant data, considered 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 for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.
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 Airbus Service Bulletin A330-57-3120, dated September 18, 2015; and Airbus Service Bulletin A340-57-5036, dated September 18, 2015. The service information describes procedures for inspecting inboard flaps using eddy current inspection methods to determine the materials used. These documents are distinct since they apply to different airplane models. 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 31 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

We estimate the following costs to do any necessary replacements that would be required based on the results of the required inspection. We have no way of determining the number of aircraft that might need these replacements:

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. The cost of purchasing a flap spare is not available. As a result, we have included only labor costs in our cost estimate.

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.
