Airworthiness Directives; Airbus Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain Airbus 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. This AD was prompted by a report of cracking in the door sill area of the aft cargo door. This AD requires repetitive inspections of the aft cargo door lower torsion box area, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective November 27, 2017.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 27, 2017.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus 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 May 22, 2017 (82 FR 23166) (``the NPRM'').
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016-0241, dated December 6, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus 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 MCAI states:
Cracks were found on in-service aeroplane post mod 5438 in the door sill area, from frame (FR) 60 to FR63, including the sill beam flag, lock fitting, door sill web and torsion door panel. Two previous cases with less crack extent were also reported.
This condition, if not detected and corrected, could lead to reduced structural integrity of the aeroplane.
To address this unsafe condition, Airbus published Inspection Service Bulletin (SB) A310-53-2139 and SB A300-53-6179 to provide inspection instructions for the affected areas. Airbus published also Airbus SB A310-53-2141 and SB A300-53-6181 to provide modification instructions.
Further analysis showed that aeroplanes pre-mod 5438, for which one or several lock fittings have been replaced by post mod 10319 lock fittings, could also be affected. Airbus published SB A310-53-
2143 and SB A300-53-6185 to provide inspection instructions.
For the reason described above, this EASA AD requires repetitive Special Detailed Inspections (SDI) of the aft cargo door lower torsion box area and, depending on findings, accomplishment of applicable corrective action(s).
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-2017-
0480.
Comment
We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA's response to that comment.
Request To Clarify Terminating Action
United Parcel Service (UPS) requested that the terminating action specified in paragraph (i) of the proposed AD be clarified to specify that the repair of a damaged fitting is terminating action for the repetitive inspections specified in paragraph (g) of the proposed AD for the repaired fitting location only. The commenter stated that this clarification would mitigate premature termination of repetitive inspections of the aft cargo door lower torsion box area.
We agree with the commenter's request for the reasons provided by the commenter. We have revised paragraph (i) of this AD to specify that repair of a lock fitting as required by paragraph (h) of this AD constitutes terminating action for the repetitive inspections required by paragraph (g) of this AD for the repaired fitting location only.
Conclusion
We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes:
Page 48911
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 A300-53-6185, dated February 11, 2016; and Service Bulletin A310-53-2143, dated February 11, 2016; which describe, among other actions, repetitive inspections of the aft cargo door sill area for cracking. 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 18 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection................. 12 work-hours x $85 $0 $1,020 per inspection $18,360 per

per inspection cycle.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that will enable us to provide a cost estimate for the on-condition corrective actions 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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division.
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.
