ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding Airworthiness Directive (AD) 98-20-27 for all 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). AD 98-20-27 required repetitive inspections to detect fatigue cracking of the wing top skin at the front spar joint; and a follow-on eddy current inspection and repair, if necessary. This new AD reduces the inspection compliance time and intervals, and expands the inspection area of the wing top skin at the front spar joint. This AD was prompted by reports of cracking of the wing top skin in an area not required for inspection by AD 98-20-27. We are issuing this AD to detect and correct fatigue cracking of the wing top skin at the front spar joint; such fatigue cracking could result in reduced structural integrity of the airplane. DATES: This AD becomes effective March 3, 2016. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 3, 2016. The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of October 29, 1998 (63 FR 50981, September 24, 1998).

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 98-20-27, Amendment 39-10793 (63 FR 50981, September 24, 1998). AD 98-20-27 applied to all 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). The NPRM published in the Federal Register on April 14, 2015 (80 FR 19892). The NPRM was prompted by reports of cracking of the wing top skin in an area not required for inspection by AD 98-20-27. The NPRM proposed to continue to require repetitive inspections to detect fatigue cracking of the wing top skin at the front spar joint; and a follow-on eddy current inspection and repair, if necessary. The NPRM also proposed to reduce the inspection compliance time and intervals, and expand the inspection area of the wing top skin at the front spar joint. We are issuing this AD to detect and correct fatigue cracking of the wing top skin at the front spar joint; such fatigue cracking 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 2013-0232R1, dated October 2, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition. The MCAI states: During full-scale fatigue testing conducted in the early 1990's, cracks were found on the top skin of the wing between Ribs 1 and 7, starting at the front spar fastener holes. This condition, if not detected and corrected, could adversely affect the structural integrity of the wing. Consequently, Airbus issued Service Bulletin (SB) A300-57-6045 and DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] France issued AD 97-374-238 [https://ad.easa.europa.eu/blob/19973740tb_superseded.pdf/AD_F-1997-374-238_2] for A300-600 aeroplanes and AD 1999-008-020 [https://ad.easa.europa.eu/blob/19980080tb_superseded.pdf/AD_F-1999-008-020_2] for A300-600ST aeroplanes to require repetitive detailed inspections of the wing top skin and, in case of findings, an Eddy Current (EC) inspection, and, depending on the size of the cracks, repair. After those [DGAC] ADs were issued, further cracks to the wing top skin were reported by operators, within an area not covered by the existing [DGAC] ADs. To address this potential unsafe condition, Airbus revised SB A300-57-6045 to extend the area to be inspected. In addition, a fleet survey and updated Fatigue and Damage Tolerance analyses were performed in order to substantiate the second A300-600 Extended Service Goal (ESG2) exercise. The results of these analyses have determined that the inspection thresholds and intervals must be reduced to allow timely detection of these cracks and the accomplishment of applicable corrective action(s). As the ESG2 exercise is only applicable to A300-600 aeroplanes, A300-600ST aeroplanes are now addressed through new Airbus SB A300- 57-9026. For the reasons described above, this [EASA] AD retains the requirements of DGAC France AD 97-374-238(B) [https://ad.easa.europa.eu/blob/19973740tb_superseded.pdf/AD_F-1997-374-238_2] [which corresponds to FAA AD 98- [[Page 4876]] 20-27, Amendment 39-10793 (63 FR 50981, September 24, 1998)] and [DGAC] AD 1999-008-020(B) [https://ad.easa.europa.eu/blob/19980080tb_superseded.pdf/AD_F-1999-008-020_2], which are superseded, but requires those actions, for A300-600 aeroplanes only, within reduced thresholds and intervals. * * * * * You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2015-0824-0003. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 19892, April 14, 2015) and the FAA's response to each comment. Support for the NPRM (80 FR 19892, April 14, 2015) United Parcel Service (UPS) stated that the proposed changes maintain the fleet airworthiness using the service experience and current certification maintenance programs for all airplanes in service. Request To Extend the Repetitive Inspection Interval UPS requested that we extend the interval for the repetitive inspections proposed in paragraph (j)(2) of the proposed AD (80 FR 19892, April 14, 2015). UPS stated that its Model A300 fleet and associated maintenance program is not certified to the ESG-2 limitations; therefore, the repetitive inspection interval should be based on the airplane certification design service goal (DSG). UPS explained that the repetitive interval extension request is due to the additional 12,000-flight-cycle service life to ensure any crack development is detected after an airplane operates beyond the 30,000- flight-cycle DSG. UPS stated that, with an extension of airplane operational life, more frequent inspections would be necessary for airplanes operating beyond the original DSG that are not necessary for an airplane operating to the airplane DSG values. We disagree with UPS's request. UPS did not provide any data to substantiate that the changed compliance time for the repetitive inspection interval provides an equivalent level of safety. Under the provisions of paragraph (o)(1) of this AD, we will consider requests for approval of an alternative method of compliance (AMOC) if sufficient data are submitted to substantiate that a revised inspection interval would provide an equivalent level of safety. We have not changed this AD in this regard. Request To Include Corrective Actions for Repetitive Inspections UPS requested that we correct the inadvertent omission of the corrective actions for the repetitive inspections in paragraph (j) of the proposed AD (80 FR 19892, April 14, 2015) by including a reference to paragraph (j) of the proposed AD in paragraphs (k)(1) and (k)(2) of the proposed AD, which specify the corrective actions. We agree with UPS to correct the inadvertent omission. We have revised paragraphs (k)(1) and (k)(2) of this AD accordingly. 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 (80 FR 19892, April 14, 2015) for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 19892, April 14, 2015). 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 Airbus has issued Service Bulletin A300-57-6045, Revision 10, dated November 13, 2013. The service information describes inspection procedures for fatigue cracking of the wing top skin at the front spar joint between ribs 1 and 7. 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 130 airplanes of U.S. registry. The actions that are required by AD 98-20-27, Amendment 39-10793 (63 FR 50981, September 24, 1998), and retained in this AD take about 2 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 are required by AD 98-20-27 is $170 per product. We also estimate that it will take about 2 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 $22,100, or $170 per product. We have received no definitive data that will enable us to provide cost estimates for the on-condition 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. 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.
