AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2004-16-01 for certain Airbus Model A330-200 and -300 series airplanes and Model A340-200 and -300 series airplanes. AD 2004-16-01 required repetitive inspections for cracking of the chromed area of the left and right piston rods for the main landing gear (MLG) retraction actuators, and related investigative and corrective actions if necessary. This new AD requires repetitive draining of any fluid from the retraction actuator piston rod internal volume and sealing of the vent hole; repetitive ultrasonic inspections of the upper end of the piston rods, and corrective actions if necessary; a one-time ultrasonic inspection (longitudinal and circumferential) of the full length of the piston rod, and corrective actions if necessary; and a terminating modification of the left-hand and right-hand MLG retraction actuators. This AD was prompted by reports of the piston rods for the MLG retraction actuators rupturing during flight. We are issuing this AD to prevent cracking of the piston rods for the MLG retraction actuators, which could result in rupture of a piston rod, non-damped extension of the MLG, high loads on the fully extended MLG, and consequent reduced structural integrity of the MLG.

DATES:

This AD becomes effective December 31, 2014.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2004-16-01, Amendment 39-13757 (69 FR 46979, August 4, 2004). AD 2004-16-01 applied to certain Airbus Model A330-200 and -300 series airplanes and Model A340-200 and -300 series airplanes. The NPRM published in the Federal Register on February 6, 2014 (79 FR 7098; corrected March 20, 2014 (79 FR 15555)). The NPRM was prompted by reports of the piston rods for the MLG retraction actuators rupturing during flight.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2011-0178R1, dated March 6, 2012, corrected March 7, 2012 (for Model A340-200 and -300 series airplanes); and EASA AD 2011-0179R1, dated March 6, 2012 (for Model A330-200 and -300 series airplanes) (both referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”); to correct an unsafe condition for the specified products. EASA AD 2011-0178R1, dated March 6, 2012, corrected March 7, 2012, states:

During an approach phase, the flight crew of an A330 aeroplane had to perform a free-fall extension of the left-hand (LH) MLG.

Rupture of the LH MLG retraction actuator piston rod was found near the rod attachment point. The inspection revealed at the location of the rupture the presence of corrosion resulting from incorrect application of the anticorrosion protection, and circumferential cracks resulting from normal operational loading effects.

Since the above rupture, new cases of crack propagation along the length of the piston rod occurred. These ruptures led to a non-damped extension of the landing gear. Fully extended, the landing gear assembly was submitted to high loads jeopardising its structural integrity.

This condition, if not detected and corrected, could lead to MLG failure during landing or roll-out and consequent damage to the aeroplane and injury to occupants.

DGAC [Direction Générale de l'Aviation Civile] France issued AD F-2005-098 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2005_​5887_​F20050980tb_​superseded.pdf/​AD_​F-2005-098_​1] (EASA approval 2005-5887) [and AD F-2005-099 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2005_​5888_​F20050990tb_​superseded.pdf/​AD_​F-2005-099_​2] (EASA approval 2005-5888)] to address this unsafe condition [the FAA issued AD 2004-16-01, Amendment 39-13757 (69 FR 46979, August 4, 2004)]. Since that [DGAC France] AD was issued, the results of extensive investigation determined that the presence of water in the internal volume of the piston rod can lead to the formation of ice which represents a potential source of high magnitude tensile hoop stresses in the material of the rod, leading to propagation of longitudinal crack in the body of the piston rod.

Prompted by these findings, EASA issued AD 2006-0301 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2006_​0301_​R2_​superseded.pdf/​AD_​2006-0301R2_​1], partially retaining the requirements of DGAC France AD F-2005-099, which was superseded, and to revise the inspection requirements as follows:

a. Extend the repetitive inspections interval for the removal of fluid from the internal volume of the piston rod using flight cycles in lieu of flight hours as this better represents the mechanism for the accumulation of water within the piston rod.

b. Remove the preliminary visual inspection from the ultrasonic longitudinal inspection of the upper end of the piston rod.

c. Add a new one-time ultrasonic longitudinal and circumferential inspection of the full piston rod length to eliminate any parts that exhibit severe corrosion along the internal length of the piston rod.

d. Require installation of new design hollow piston rod Part Number (P/N) 114256328 (Airbus mod. 52980—SB A340-32-4222 Revision 01) without a vent hole, thus eliminating moisture ingress as the terminating action.

EASA AD 2006-0301 was later revised:

—at revision 01, to correct a number of typographical errors and to add reference to Airbus SB A340-32-4212 Revision 04, and

—at revision 02 to extend the inspections threshold from 3 to 6 years in service usage for retraction actuator piston rod P/N 114256321 issue 06 which was re-identified to P/N 114256326 issue 01 in accordance with the instructions of Airbus SB A340-32-4260.

More recently, the sampling of piston rod P/N 114256326 issue 1 and P/N 114256321 issue 06 have confirmed the need to replace all retraction actuator piston rods with a piston rod P/N114256328.

For the reasons described above, this [EASA] AD at original issue retained the requirements of EASA AD 2006-0301R2 (http://ad.easa.europa.eu/​blob/​easa_​ad_​2006_​0301_​R2_​superseded.pdf/​AD_​2006-0301R2_​1), which is superseded, and required the replacement of all retraction actuator piston rods with a piston rod P/N 114256328, which constitutes terminating action to the repetitive requirements of this AD.

This [EASA] AD is revised to clarify that aeroplanes on which Airbus mod. 52980 has been embodied in production are not required to accomplish the reidentification of MLG retraction actuator P/N 114256002-055 which is mentioned in the accomplishment instructions of Airbus SB A340-32-4222 Revision 03.

This [EASA] AD has been republished to correct a typographical mistake of the applicable Airbus SB number in the Applicability (in the Note) and in the Reason sections of this [EASA] AD.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 7098, February 6, 2014; corrected March 20, 2014 (79 FR 15555)), and the FAA's response to each comment.

Request To Reference Latest Service Information

Delta Airlines requested that we reference the latest Airbus service information, which is Airbus Service Bulletin A330-32-3180, Revision 05, dated January 27, 2014. Delta Airlines further requested that we provide credit for actions previously accomplished using Airbus Service Bulletin A330-32-3180, Revision 03, dated January 28, 2011; and Airbus Service Bulletin A330-32-3180, Revision 04, dated July 30, 2013.

We agree with Delta Airlines' comment to reference the latest service information. Airbus Service Bulletin A330-32-3180, Revision 05, dated January 27, 2014, provides the latest information on the modification required by this AD. This service bulletin specifies two additional work-hours for re-identification of the part number of the MLG retraction actuator for Model A330-200 and -300 series airplanes at configuration 3, which were modified as described in Airbus Service Bulletin A330-32-3180, Revision 03, dated January 28, 2011. Re-identification of the MLG retraction actuator may be considered as a logical outgrowth of the proposed AD (79 FR 7098, February 6, 2014; corrected March 20, 2014 (79 FR 15555)) requirements.

Airbus has also released Service Bulletin A340-32-4222, Revision 04, dated July 30, 2013. This service bulletin also specifies two additional work-hours for re-identification of the part number of the MLG retraction actuator for Model A340 series airplanes. There are currently no U.S.-registered Model A340 series airplanes. We have revised paragraphs (s) and (t) of this AD to specify Airbus Service Bulletin A330-32-3180, Revision 05, dated January 27, 2014; and Airbus Service Bulletin A340-32-4222, Revision 04, dated July 30, 2013; as the appropriate sources of service information for the required actions in those paragraphs. We have also revised paragraphs (w)(2) and (w)(3) of this AD to provide credit for previous actions Start Printed Page 70449accomplished using Airbus Service Bulletin A330-32-3180, Revision 03, dated January 28, 2011; Airbus Service Bulletin A330-32-3180, Revision 04, dated July 30, 2013; and Airbus Service Bulletin A340-32-4222, Revision 03, dated January 28, 2011; as applicable.

“Contacting the Manufacturer” Paragraph in This AD

Since late 2006, we have included a standard paragraph titled “Airworthy Product” in all MCAI ADs in which the FAA develops an AD based on a foreign authority's AD.

The MCAI or referenced service information in an FAA AD often directs the owner/operator to contact the manufacturer for corrective actions, such as a repair. Briefly, the Airworthy Product paragraph allowed owners/operators to use corrective actions provided by the manufacturer if those actions were FAA-approved. In addition, the paragraph stated that any actions approved by the State of Design Authority (or its delegated agent) are considered to be FAA-approved.

In the NPRM (79 FR 7098, February 6, 2014; corrected March 20, 2014 (79 FR 15555)), we proposed to prevent the use of repairs that were not specifically developed to correct the unsafe condition, by requiring that the repair approval provided by the State of Design Authority or its delegated agent specifically refer to this FAA AD. This change was intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we proposed to change the phrase “its delegated agent” to include a design approval holder (DAH) with State of Design Authority design organization approval (DOA), as applicable, to refer to a DAH authorized to approve required repairs for the proposed AD.

No comments were provided to the NPRM (79 FR 7098, February 6, 2014; corrected March 20, 2014 (79 FR 15555)) about these proposed changes. However, a comment was provided for an NPRM having Directorate Identifier 2012-NM-101-AD (78 FR 78285, December 26, 2013). The commenter stated the following: “The proposed wording, being specific to repairs, eliminates the interpretation that Airbus messages are acceptable for approving minor deviations (corrective actions) needed during accomplishment of an AD mandated Airbus service bulletin.”

This comment has made the FAA aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an AD-mandated action. The Airworthy Product paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19.

To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed the paragraph and retitled it “Contacting the Manufacturer.” This paragraph now clarifies that for any requirement in this AD to obtain corrective actions from a manufacturer, the actions must be accomplished using a method approved by the FAA, the European Aviation Safety Agency (EASA), or Airbus's EASA Design Organization Approval (DOA).

The Contacting the Manufacturer paragraph also clarifies that, if approved by the DOA, the approval must include the DOA-authorized signature. The DOA signature indicates that the data and information contained in the document are EASA-approved, which is also FAA-approved. Messages and other information provided by the manufacturer that do not contain the DOA-authorized signature approval are not EASA-approved, unless EASA directly approves the manufacturer's message or other information.

This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers' service instructions that are “Required for Compliance” with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance.

Other commenters to the NPRM having Directorate Identifier 2012-NM-101-AD (78 FR 78285, December 26, 2013) pointed out that in many cases the foreign manufacturer's service bulletin and the foreign authority's MCAI might have been issued some time before the FAA AD. Therefore, the DOA might have provided U.S. operators with an approved repair, developed with full awareness of the unsafe condition, before the FAA AD is issued. Under these circumstances, to comply with the FAA AD, the operator would be required to go back to the manufacturer's DOA and obtain a new approval document, adding time and expense to the compliance process with no safety benefit.

Based on these comments, we removed the requirement that the DAH-provided repair specifically refer to this AD. Before adopting such a requirement, the FAA will coordinate with affected DAHs and verify they are prepared to implement means to ensure that their repair approvals consider the unsafe condition addressed in this AD. Any such requirements will be adopted through the normal AD rulemaking process, including notice-and-comment procedures, when appropriate.

We also have decided not to include a generic reference to either the “delegated agent” or “DAH with State of Design Authority design organization approval,” but instead we have provided the specific delegation approval granted by the State of Design Authority for the DAH.

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 changes:

  • Are consistent with the intent that was proposed in the NPRM (79 FR 7098, February 6, 2014; corrected March 20, 2014 (79 FR 15555)) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 7098, February 6, 2014; corrected March 20, 2014 (79 FR 15555)).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

Costs of Compliance

We estimate that this AD affects 24 Model A330-200 and -300 series airplanes of U.S. registry. There are no Start Printed Page 70450Model A340-200 or -300 series airplanes of U.S. registry.

We estimate that it will take about 67 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $56,000 per product (2 actuators). Based on these figures, we estimate the cost of this AD on U.S. operators to be $1,480,680, or $61,695 per product.

In addition, we estimate that any necessary follow-on actions will take about 38 work-hours and require parts costing $56,000 (2 actuators), for a cost of $59,230 per product. We have no way of determining the number of aircraft that might need these actions.

According to the manufacturer, some of the costs of 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.

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 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 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.
