2017-13949. Airworthiness Directives; Airbus Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2013-10-03, which applied to all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. AD 2013-10-03 required one-time inspections for deformation and damage of the bogie beams of the main landing gear (MLG); repetitive inspections for damage and corrosion of the sliding piston sub-assembly on certain airplanes; and related investigative and corrective actions if necessary. This new AD removes Model A340-500 and 600 series airplanes from the applicability; removes certain one-time inspections of the MLG bogie beams and the sliding piston sub-assembly; revises certain compliance times; and requires replacement of certain MLGs with MLGs having an improved bogie beam, which constitutes terminating action for the repetitive inspections on the modified MLG. This AD was prompted by reports of corroded and cracked bogie beams under the bogie stop pad. We are issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective August 10, 2017.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 10, 2017.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2013-10-03, Amendment 39-17456 (78 FR 31386, May 24, 2013) (“AD 2013-10-03”). AD 2013-10-03 applied to all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. The SNPRM published in the Federal Register on March 22, 2017 (82 FR 14642) (“the SNPRM”). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on March 1, 2016 (81 FR 10540) (“the NPRM”). The NPRM was prompted by reports of corroded and cracked bogie beams under the bogie stop pad. The NPRM proposed to remove Model A340-500, and -600 series airplanes from the applicability, remove certain one-time inspections of the MLG bogie beams and the sliding piston sub-assembly; revise certain compliance times and provide, for certain airplanes, an optional terminating action for the repetitive actions. The SNPRM proposed to require replacement of a MLG having part number (P/N) 201252 series and P/N 201490 series with a MLG that has an improved bogie beam, which would constitute terminating action for the repetitive inspections on the modified MLG. We are issuing this AD to detect and correct damage or corrosion under the bogie stop pad of both MLG bogie beams; this condition could result in a damaged bogie beam and consequent detachment of the beam from the airplane, collapse of the MLG, or departure of the airplane from the runway, possibly resulting in damage to the airplane and injury to occupants.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016-0108, dated June 8, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200 and -300 series airplanes. The MCAI states:

During a scheduled maintenance inspection on the Main Landing Gear (MLG), the bogie stop pad was found deformed and cracked. Upon removal of the bogie stop pad for replacement, the bogie beam was also found cracked. The results of a laboratory investigation indicated that an overload event had occurred and no fatigue propagation of the crack was evident. A second bogie beam crack was subsequently found on another aeroplane, located under a bogie stop pad which only had superficial paint damage.

This condition, if not detected and corrected, could lead to landing gear bogie detachment from the aeroplane, or landing gear collapse, or a runway excursion, possibly resulting in damage to the aeroplane and injury to the occupants and/or people on the ground.

To address this potential unsafe condition, EASA issued AD 2008-0223 [which corresponds to FAA AD 2010-02-10, Amendment 39-16181 (75 FR 4477, January 28, 2010)] to require accomplishment of a one-time detailed inspection under the bogie stop pad of both MLG bogie beams. As a result of the one-time inspection required by that [EASA] AD, numerous bogie stop pad were found corroded and a few cracked. The one-time inspection was retained in EASA AD 2011-0211 [which corresponds to FAA AD 2013-10-03], which superseded EASA AD 2008-0223, which also introduced repetitive inspections, except for A340-500/-600 aeroplanes.

After EASA AD 2011-0211 was issued, further investigation led to the conclusion that the one-time inspection was no longer necessary and only the repetitive inspections should remain. In addition, it was determined that repetitive inspections were also necessary for MLG on A340-500/-600 aeroplanes.

Prompted by these conclusions, EASA issued AD 2014-0120, partially retaining the requirements of EASA AD 2011-0211, which was superseded, and introducing repetitive detailed inspections of the MLG on A340-500 and A340-600 aeroplanes. Subsequently, further analysis indicated that repetitive inspections of the MLG on A340-500/-600 aeroplanes were not necessary after all. In addition, the threshold for the inspection of MLG P/N 10-210 series was raised from 24 to 126 months, and Airbus developed a modification of the MLG P/N 10-210 series which provides an (optional) terminating action for the repetitive inspections.

Consequently, EASA AD 2014-0120 was revised to delete the requirements for A340-500/-600 aeroplanes, to amend the inspection threshold for MLG P/N 10-210 series, and to introduce an optional terminating action for aeroplanes with MLG P/N 10-210 series.

Since EASA AD 2014-0120R1 was issued, Airbus developed a modification (mod 205289) of the MLG P/N 201252 series and P/N 201490 series that must be embodied in service with Airbus SB A330-32-3275 or SB A340-32-4305. It was also identified that A340-500/-600 aeroplanes could be removed from the applicability of this [EASA] AD as no more actions were required on these aeroplanes.

For the reason described above, this [EASA] AD retains the requirements of EASA AD 2014-0120R1, which is superseded, removes the A340-500/-600 aeroplanes from the Applicability and requires the modification of the MLG P/N 201252 series and P/N 201490 series, which constitutes terminating action for the repetitive inspections required by this [EASA] AD.

The required actions include repetitive detailed inspections for damage and corrosion of the sliding piston sub-assembly, and related investigative and corrective actions if necessary. Related investigative actions include a test for indications of corrosion and damage to the bogie assembly base material, and a magnetic particle inspection for cracks, corrosion, and damage of the bogie beam. Corrective actions include repairing affected parts.

The required terminating action (for a MLG having P/N 201252 series or P/N 201490 series) and the optional terminating action (for a MLG having P/N 10-210 series) are modifications of the bogie beam of a MLG, which consist of installing a nickel under chrome coating, a new bogie beam stop pad, and new stop pad brackets.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comment received. Air Line Pilots Association, International supported the SNPRM.

Conclusion

We reviewed the available data, including the comment received, 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.

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 89 Model A330-200, -200 Freighter, and -300 series airplanes of U.S. registry.

We estimate that it will take about 13 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 $98,345, or $1,105 per product.

Currently, there are no Model A340-200 or -300 series airplanes on the U.S. Register. However, if an affected airplane is imported and placed on the U.S. Register in the future, it would be subject to the same per-airplane cost specified above for the Model A330-200, -200 Freighter, and -300 series airplanes.

In addition, we estimate that any necessary follow-on actions will take about 24 work-hours and require parts costing $78, for a cost of $2,118 per product. We have no way of determining the number of aircraft that might need these actions.

According to the manufacturer, all of the parts costs of the optional terminating action specified in this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. We have received no definitive data that would enable us to provide the work-hour cost estimates for the optional terminating action 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.
