AD 2016-18-07

We are superseding Airworthiness Directive (AD) 2009-15-17 for certain Airbus Model A330-200 and -300 series airplanes; and Model A340-200 and -300 series airplanes. AD 2009-15-17 required an inspection for damage to the protective treatments or any corrosion of all main landing gear (MLG) bogie beams, and application of protective treatments if no damage or corrosion was found. If any damage or corrosion was found, corrective action followed by the application of protective treatments was required. This new AD continues 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. This new AD also requires modification of the MLG bogie beams, which terminates the repetitive inspections for any modified bogie beam. This new AD allows optional methods of compliance for certain actions, and adds Airbus Model A330-200 Freighter series airplanes to the applicability.This new AD revises the compliance times and adds a one-time inspection for airplanes that were inspected too early. This AD was prompted by reports of thin paint coats and paint degradation on enhanced main landing gear (MLG) bogie beams, as well as reports that some airplanes have been inspected too early and not re-inspected as needed. We are issuing this AD 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.

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:

[[Page 66521]]

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 removing Airworthiness Directive (AD) 2009-15-17, Amendment 39-15980 (74 FR 37523, July 29, 2009), and adding the following new AD:

Discussion

We issued a second supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2009-15-17, Amendment 39-15980 (74 FR 37523, July 29, 2009) (``AD 2009-15-17''). AD 2009-15- 17 applied to certain Airbus Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. The second SNPRM published in the Federal Register on February 5, 2016 (81 FR 6185) (``the second SNPRM''). We preceded the second SNPRM with the first SNPRM, which was published in the Federal Register on March 5, 2014 (79 FR 12414) (``the first SNPRM''). We preceded the first SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on September 25, 2013 (78 FR 58978) (``the NPRM''). The NPRM was prompted by reports of thin paint coats and paint degradation on enhanced MLG bogie beams. The NPRM proposed 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 first SNPRM proposed to revise the compliance times and add a one-time inspection for airplanes that were inspected too early. The second SNPRM proposed to clarify the required actions and the specific configurations to which the actions must be applied. We are issuing this AD 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.
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 for 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 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, 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 [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 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 afteroverhaul) 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).

Comments

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

Request To Revise the Applicability of theSecond SNPRM

American Airlines (AAL) requested that we revise the applicability of the proposed AD (in the second SNPRM) to exclude airplanes with MLG bogie beams that have had Airbus modification 58896 embodied in- service, as specified in Airbus Service Bulletin A330-32-3237. AAL pointed out that paragraph (c) of the proposed AD (in the second SNPRM) does not reflect MLG bogie beams that were modified in-service.
We disagree with the request to revise the applicability of the proposed AD (in the second SNPRM). Paragraph (k) of this AD specifically requires inspection, repair, modification, and re- identification of the MLG bogie beams. However, paragraph (f) of this AD states that actions already done need not be repeated. If an operator has already accomplished the actions required by paragraph (k) of this AD before the effective date of this AD, then the modified airplane is already in compliance with the corresponding requirements of this AD. We have not made any changes to this AD in this regard.

Additional Changes Made in This AD

We have revised paragraph (m)(1) of this AD to remove reference to paragraph (g) of this AD; the reporting requirement specified in paragraph (m)(1) of this AD is required only for the

[[Page 66520]]

inspection required by paragraph (k) of this AD.
We have also revised paragraph (m)(2) of this AD to reference the correct service information for reporting inspection findings for the inspection required by paragraph (h) of this AD.

Conclusion

We reviewed the available data, including the comment 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 second SNPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the second SNPRM.

Costs of Compliance

We estimate that this AD affects 51 airplanes of U.S. registry.
We also estimate that it takes about 34 work-hours per product to comply with this 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 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-hoursat a labor rate of $85 per work-hour, 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 AD is 2120- 0056. The paperwork cost associated with this 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 AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directedto 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 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.
