Airworthiness Directives; Airbus Airplanes

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.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 31, 
2014.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

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 G[eacute]n[eacute]rale 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

[[Page 70449]]

accomplished 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

[[Page 70450]]

Model 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.

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2004-16-01, Amendment 39-13757 (69 FR 46979, August 4, 2004), and 
adding the following new AD:

2014-23-07 Airbus: Amendment 39-18023. Docket No. FAA-2014-0132; 
Directorate Identifier 2012-NM-007-AD.

(a) Effective Date

    This AD becomes effective December 31, 2014.

(b) Affected ADs

    This AD replaces AD 2004-16-01, Amendment 39-13757 (69 FR 46979, 
August 4, 2004).

(c) Applicability

    This AD applies to Airbus Model A330-201, -202, -203, -223, -
243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 
airplanes; and Model A340-211, -212, -213, -311, -312, and -313

Gear.

(e) Reason

    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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Detailed Inspections

    At the applicable time specified in paragraph (g)(1) or (g)(2) 
of this AD: Do a detailed inspection for cracking of the visible 
chromed area of the MLG retraction actuator piston rods in the fully 
extended position, in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A330-32-3173, Revision 05, 
dated September 26, 2008 (for Model A330-200 and -300 series 
airplanes); or Airbus Service Bulletin A340-32-4212, Revision 05, 
dated September 26, 2008 (for Model A340-200 and -300 series 
airplanes). Repeat the inspection thereafter at intervals not to 
exceed 8 days until the actions required by paragraphs (j) and (o) 
of this AD are accomplished.
    (1) For MLG retraction actuator piston rods that have not had a 
detailed inspection accomplished as of the effective date of this 
AD, as described in any applicable service information specified in 
paragraph (h)(1) or (h)(2) of this AD: At the applicable time

[[Page 70451]]

specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD.
    (i) For MLG retraction actuator piston rods having part number 
(P/N) 114256309 or P/N 114256321 issue 03: Do the inspection within 
60 days after the effective date of this AD, or before the MLG 
retraction actuator has been in service 36 months, whichever occurs 
later.
    (ii) For MLG retraction actuator piston rods having P/N 
114256326 issue 01 or P/N 114256321 issue 06: Do the inspection 
within 60 days after the effective date of this AD, or before the 
MLG retraction actuator has been in service 72 months, whichever
