Airworthiness Directives; Airbus Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.
-----------------------------------------------------------------------
SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for certain Airbus Model A330-200 and -300 series airplanes; and Model A340-200 and -300 series airplanes. The NPRM proposed to supersede AD 2009-15-17 to continue to require inspections for damage to the protective treatments or any corrosion of all main landing gear (MLG) bogie beams, application of protective treatments, and corrective action if necessary. The NPRM also proposed to require modification of the MLG bogie beams, to allow optional methods of compliance for certain actions, and to add airplanes to the applicability. The first supplemental notice of proposed rulemaking (SNPRM) proposed to revise the compliance times and add a one-time inspection for certain airplanes. The NPRM was prompted by reports of thin paint coats and paint degradation on enhanced MLG bogie beams. This second SNPRM proposes to clarify the required actions and the specific configurations to which the actions must be applied. We are proposing this second SNPRM to detect and correct damage or corrosion of the MLG bogie beams, which could cause a runway excursion event, bogie beam detachment from the airplane, or MLG collapse, and could result in damage to the airplane and injury to the occupants. Since these actions impose an additional burden over those proposed in the first SNPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
DATES: We must receive comments on this SNPRM by March 21, 2016.

Discussion
We issued an SNPRM to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A330-200 Freighter series airplanes, Model A330-200 and A330-300 series airplanes, and Model A340-200 and A340-300 series airplanes. The SNPRM published in the Federal Register on March 5, 2014 (79 FR 12414).
We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on September 25, 2013 (78 FR 58978). The NPRM was prompted by reports of thin paint coats and paint degradation on enhanced MLG bogie beams. The NPRM proposed to supersede AD 2009-15-17, Amendment 39-15980 (74 FR 37523, July 29, 2009), to continue to require inspections for damage to the protective treatments or any corrosion of all MLG bogie beams, application of protective treatments, and corrective action if necessary. The NPRM also proposed to require modification of the MLG bogie beams, which would terminate the repetitive inspections for any modified bogie beam. In addition, the NPRM proposed to allow optional methods of compliance for certain actions, and to add Airbus Model A330-200 Freighter series airplanes to the applicability.
The SNPRM (79 FR 12414, March 5, 2014) (``the first SNPRM'') proposed to revise the compliance times and add a one-time inspection for airplanes that were inspected too early.
Actions Since the First SNPRM Was Issued
Since we issued the first SNPRM, we have determined that it is necessary to clarify the required actions and the specific configurations to which the actions must be applied. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2013-0267R1, dated March 4, 2014, Corrected May 8, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition on certain Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Model A340-200 and -300 series airplanes. The MCAI states:
The operator of an A330 aeroplane (which has a common bogie beam with the A340) reported a fracture of the Right Hand (RH) main landing gear (MLG) bogie beam, which occurred while turning during low speed taxi maneuvers. The bogie fractured aft of the pivot point and remained attached to the sliding tube by the brake torque reaction rods. After this RH bogie failure, the aeroplane continued for approximately 40 meters on the forks of the sliding member before coming to rest on the taxiway.
The investigations revealed that this event was due to corrosion pitting occurring on the bore of the bogie beam.
This condition, if not detected and corrected, could lead to a runway excursion event or to detachment of the bogie from the aeroplane, or to MLG collapse, possibly resulting in damage to the aeroplane and injury to the occupants.
To enable early detection and repair of corrosion of the internal surfaces, EASA issued EASA AD 2007-0314 http://ad.easa.europa.eu/ad/2007-0314R1 to require a one-time inspection of all MLG bogie beams, except Enhanced MLG bogie beams, and the reporting of the results to Airbus. EASA AD 2007-0314 was revised and later superseded by EASA AD 2008-0093 http://ad.easa.europa.eu/ad/2008-0093, reducing the inspection threshold period.
The results of subsequent investigations showed thin paint coats and paint degradation, confirmed as well on Enhanced MLG bogie beams. To address this additional concern, EASA issued AD 2011-0141 http://ad.easa.europa.eu/ad/2011-0141 which was not mandated by the FAA, retaining the requirements of EASA AD 2008-0093, which was superseded, to require a one-time visual inspection of all MLG bogie beams, including a visual examination of the internal diameter for corrosion or damage to protective treatments of the bogie beam and measurement of the paint thickness on the internal bore, accomplishment of the applicable corrective actions and a modification of the MLG bogie beam to improve the coat paint application method, and application of corrosion protection.
Prompted by in-service requests, EASA issued EASA AD 2012-0015 http://ad.easa.europa.eu/ad/2012-0015 corresponds with FAA NPRM (78 FR 58978, September 25, 2013) retaining the requirements of EASA AD 2011-0141, which was superseded, and introducing repetitive inspections of the MLG bogie beams, which allows extension of the compliance time for the MLG bogie beam modification from 15 years to 21 years. Modification of a MLG bogie beam constitutes terminating action for the repetitive inspections for that MLG bogie beam.
Reports on inspection results provided to Airbus show that some aeroplanes were initially inspected too early (before 4 years and 6 months since aeroplane first flight with bogie beam installed/
installed after overhaul) and have not been re-inspected as required.
For the reasons described above, this EASA AD retains the requirements of EASA AD 2012-0015, which is superseded, and redefines the inspection periodicity. This EASA AD also introduces a specific one-time inspection for aeroplanes that have been inspected too early.
Prompted by operator comments, this EASA AD is revised to clarify the required actions and the specific configurations to which the actions must be applied. Appendix 1 of this EASA AD has been amended accordingly.
This EASA AD is republished to editorially correct paragraph (4).

0828.

Change to the First SNPRM
Since the first SNPRM was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, paragraphs (m)(1) and (m)(2) of the proposed AD (in the first SNPRM) have been redesignated as paragraphs (n)(1) and (n)(2) of this proposed AD.
Comments
We gave the public the opportunity to participate in developing this proposed AD. We considered the comment received.
Request To Revise Paragraph (l) of the Proposed AD (in the First SNPRM)
Air France requested that we revise paragraph (l) of the proposed AD (in the first SNPRM) by changing the references to paragraphs (n)(1) and (n)(2) to refer to paragraphs (m)(1) and (m)(2).
We agree that the optional terminating action paragraph should refer to the optional methods of compliance paragraphs, which are paragraphs (m)(1) and (m)(2) of the proposed AD (in the first SNPRM). However, no change to this proposed AD is necessary because those paragraphs have been redesignated as paragraphs (n)(1) and (n)(2).
FAA's Determination and Requirements of This SNPRM
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs.
Certain changes described above expand the scope of the first SNPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM.
Differences Between This SNPRM and the MCAI or Service Information
The MCAI specifies repair and corrective actions in accordance with Airbus Mandatory Service Bulletin A330-32-3225, Revision 02, dated October 26, 2012; or A340-32-4268, Revision 03, dated January 14, 2013. However, Airbus Mandatory Service Bulletins A330-32-3225, Revision 02, dated October 26, 2012; and A340-32-4268, Revision 03, dated January 14, 2013; do not describe repair and corrective actions. Paragraphs (i) and (j) of this proposed AD specify repair and corrective actions in accordance with Messier-Dowty Service Bulletin A33/34-32-272, Revision 1, including Appendices A, B, C, and D, dated September 22, 2008. This difference has been coordinated with Airbus.
Costs of Compliance
We estimate that this proposed AD affects 51 airplanes of U.S. registry.
We also estimate that it would take about 34 work-hours per product to comply with the new basic requirements of this proposed AD, and 1 work-hour per product for reporting. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $151,725, or $2,975 per product.
In addition, we estimate that any necessary follow-on actions would take about 10 work-hours, for a cost of $850 per product. We have no way of determining the number of aircraft that might need these actions.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this proposed AD is 2120-0056. The paperwork cost associated with this proposed AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this proposed AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200.
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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
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.
