We are superseding Airworthiness Directive (AD) 2011-17-

[[Page 24036]]

09 for all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and AD 2012-25-12 for all Airbus Model A330-200 and -300 series airplanes. AD 2011-17-09 required revisions to certain operator maintenance documents to include new inspections. AD 2012-25-12 required replacing certain main landing gear (MLG) bogie beams before reaching new reduced life limits. This new AD requires revising the maintenance or inspection program, as applicable, to incorporate new, more restrictive, or revised instructions and/or airworthiness limitation requirements. This AD was prompted by revisions to certain airworthiness limitation item (ALI) documents, which specify more restrictive instructions and/or airworthiness limitations. 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:

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2011-17-09, Amendment 39-16773 (76 FR 53305, August 26, 2011) (``AD 2011-17-09''); and AD 2012-25-12, Amendment 39-17293 (77 FR 75825, December 26, 2012) (``AD 2012-25- 12''). AD 2011-17-09 applied to all Airbus Model A330-200, -200 Freighter, and -300 series airplanes. AD 2012-25-12 applied to all Airbus Model A330-200 and -300 series airplanes. The SNPRM published in the Federal Register on December 16, 2016 (81 FR 91062). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on January 13, 2016 (81 FR 1570). The NPRM was prompted by a determination that more restrictive instructions and/or airworthiness limitations should be incorporated into the maintenance or inspection program, as applicable. The NPRM proposed to require revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. The SNPRM proposed to require revising the maintenance or inspection program, as applicable, to incorporate more restrictive instructions and/or airworthiness limitations that the manufacturer has recently issued. We are issuing this AD to detect and correct fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, 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, 2014-0009, dated January 8, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340- 200, -300, -500, and -600 series airplanes. The MCAIstates:

The airworthiness limitations for Airbus aeroplanes are currently published in Airworthiness Limitations Section (ALS) documents.
The instructions and airworthiness limitations applicable to the Safe Life Airworthiness Limitation Items (SL ALI) are given in Airbus A330 ALS Part 1 and A340 ALS Part 1, which are approved by EASA.
The revision 07 of Airbus A330 and A340 ALS Part 1 introduces more restrictive instructions and/or airworthiness limitations. Failure to comply with this revision could result in an unsafe condition.
For the reason described above, this [EASA] AD retains the requirements of EASA AD 2012-0179, which is superseded, and requires accomplishment of the actions specified in Airbus A330 or A340 ALS Part 1 revision 07.
In addition, this [EASA] AD also supersedes EASA AD 2011-0122-E and EASA AD 2011-0212, whose requirements have been transferred into Airbus A330 and A340 ALS Part 1 revision 07.

The unsafe condition is fatigue cracking,accidental damage, or corrosion in certain principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane. 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-2015-8428.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the SNPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the SNPRM.

Related Service Information Under1 CFR Part 51

Airbus has issued Airbus A330 ALS Part 1, SL-ALI, Revision 08, dated April 11, 2016. Messier-Bugatti-Dowty has issued Service Letter A33-34 A20, Revision 7, including Appendixes A through F, dated July 20, 2012. This service information describes SL-ALI for the landing gear. This service information is distinct since it was issued by two different manufacturers for different purposes.
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 82 airplanes of U.S. registry.
The actions that are required by AD 2011-17-09, and retained in this AD, take about 1 work-hour 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 2011-17-09 is $85 per product.
The actions that are required by AD 2012-25-12, and retained in this AD, take about 16 work-hours, at an average labor rate of $85 per work-hour, with required parts cost of about $255,000 per MLG bogie beam. Based on these figures, the estimated cost of the actions that are required by AD 2012-25-12 is up to $256,360 per MLG bogie beam.
We also estimate that it would take about 1 work-hour 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 $6,970, or $85 per product.

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.
