Airworthiness Directives; Airbus Airplanes
Publication summary
We are superseding Airworthiness Directive (AD) 2012-06-19 for certain Airbus Model A330-201, -202, -203, -223, -243, -301, -302, - 303, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340- 200 and -300 series airplanes. AD 2012-06-19 required repetitive inspections of the main fitting and sliding tube of the nose landing gear (NLG) for defects, damage, and cracks; and corrective actions if necessary. This new AD requires an inspection of the part number and serial number of the NLG main fitting and NLG sliding tube; for affected parts, this new AD requires a magnetic particle inspection (MPI) for cracks, and flap peening and replacement if necessary. This new AD also requires, for certain parts, additional inspections for damage and cracking. This new AD also adds airplanes to the applicability. This AD was prompted by reports of a cracked main fitting and sliding tube during NLG overhaul. We are issuing this AD to detect and correct cracks, defects, or damage of the main fitting or sliding tube, which could result in consequent NLG collapse.

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-06-19 for
certain Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -
303, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-
200 and -300 series airplanes. AD 2012-06-19 required repetitive
inspections of the main fitting and sliding tube of the nose landing
gear (NLG) for defects, damage, and cracks; and corrective actions if
necessary. This new AD requires an inspection of the part number and
serial number of the NLG main fitting and NLG sliding tube; for
affected parts, this new AD requires a magnetic particle inspection
(MPI) for cracks, and flap peening and replacement if necessary. This
new AD also requires, for certain parts, additional inspections for
damage and cracking. This new AD also adds airplanes to the
applicability. This AD was prompted by reports of a cracked main
fitting and sliding tube during NLG overhaul. We are issuing this AD to
detect and correct cracks, defects, or damage of the main fitting or
sliding tube, which could result in consequent NLG collapse.
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 2012-06-19, Amendment 39-17000 (77 FR 22188,
April 13, 2012). AD 2012-06-19 applied to certain Airbus Model A330-
201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341,
-342, and -343 airplanes; and Model A340-200 and -300 series airplanes.
The NPRM published in the Federal Register on June 30, 2014 (79 FR
36666).
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2013-0179, dated August 7, 2013 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Airbus Model
A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321,
-322, -323, -341, -342, and -343 airplanes; and Model A340-200 and -300
series airplanes. The MCAI states:
During the overhaul of two different Nose Landing Gear (NLG)
units, cracks were found on the main fitting of one and the sliding
tube of the other. Investigations concluded that the cracks
initiated as a result of residual stress in the parts, following
damage due to impact during towing incidents.
A subsequent review of the reported incidents identified a
specific group of NLG main fittings and sliding tubes that may have
sustained impact damage as a result of towing incidents.
This condition, if not detected and corrected could lead to NLG
collapse.
To address this potential unsafe condition, EASA issued AD 2010-
0034 [(http://ad.easa.europa.eu/blob/easa_ad_2010_0034_Corrected_superseded.pdf/AD_2010-0034_1) [which
corresponds to FAA AD 2012-06-19, Amendment 39-17000 (77 FR 22188,
April 13, 2012)] to require accomplishment of a one-time Magnetic
Particles Inspection (MPI), followed by repetitive Detailed Visual
Inspections (DVI) of the main fittings and sliding tubes of the
affected NLG units identified by Part Number (P/N) and Serial Number
(S/N) in the Applicability section of that AD and, depending on
findings, accomplishment of applicable corrective actions.
Since that [EASA] AD was issued, it has been found necessary to
address the issue at the level of NLG detail parts and no longer at
NLG assembly level, as some detail parts have been transferred from
an aeroplane to another. Airbus revised the applicable Service
Bulletins (SB), which now list the affected NLG main fittings and
sliding tubes.
For the reasons described above, this [EASA] AD retains
[certain] requirements of EASA AD 2010-0034 which is superseded and
requires [an inspection of the part number and serial number of the
NLG main fitting and NLG sliding tube, and for affected parts,] a
one-time MPI [for cracks], followed by repetitive DVI [for cracking,
damage to paint, sealant, cadmium, and base metal] of the affected
NLG main fittings and sliding tubes and, depending on inspection
results, accomplishment of corrective actions [e.g., flap peening
and replacing cracked parts]. This AD also extends the applicability
to A330 freighters.
You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0425-0002.
Clarification of Service Information References
We have clarified the service information references in this AD to
identify the appendices.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the NPRM (79 FR
36666, June 30, 2014) and the FAA's response to each comment.
Request to Reference Service Information Instead of Table
Air France requested that we revise paragraph (g) of the NPRM (79
FR 36666, June 30, 2014), to replace table 1 to paragraph (g) of the
NPRM with references to Airbus Service Bulletin A330-32-3233, Revision
02, including Appendix 01, dated January 27, 2014; and Airbus Service
Bulletin A340-32-4275, Revision 01, including Appendix 01, dated July
5, 2013. Air France asserted that the main reason for superseding AD
2012-06-19, Amendment 39-17000 (77 FR 22188, April 13, 2012), is to
address the issue at the level of NLG detail parts and no longer at the
NLG assembly level, as some detail parts have been transferred from one
airplane to another.
We agree with the commenter that Airbus Service Bulletin A330-32-
3233, Revision 02, including Appendix 01, dated January 27, 2014; and
Airbus Service Bulletin A340-32-4275, Revision 01, including Appendix
01, dated July 5, 2013, contain the NLG detail parts (NLG main fitting
and NLG sliding tube). However, paragraph (g) of this AD is a
requirement that is retained from AD 2012-06-19, Amendment 39-17000 (77
FR 22188, April 13, 2012) and only restates the affected parts
identified in that AD. Paragraphs (i) and (j) of this AD require
inspecting for affected NLG main fittings and NLG sliding tubes
identified in the service information and inspecting affected parts for
cracks. Accomplishing the new requirements specified in paragraph (j)
of this AD terminates the actions specified in paragraph (g) of this
AD. Therefore, no changes were made to this AD in this regard.
``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.
We have become 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
[[Page 70460]]
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.
We also have decided not to include a generic reference to either
the ``delegated agent'' or ``design approval holder (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 minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (79 FR 36666, June 30, 2014) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 36666, June 30, 2014).
Costs of Compliance
We estimate that this AD affects 92 airplanes of U.S. registry.
The actions that were required by AD 2012-06-19, Amendment 39-17000
(77 FR 22188, April 13, 2012), that are retained in this AD take about
4 work-hours per product, at an average labor rate of $85 per work-
hour. Required parts cost about $0 per product. Based on these figures,
the estimated cost of the actions that were required by AD 2012-06-19
is $31,280 per product.
We also estimate that it will take about 10 work-hours per product
to comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $0 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $78,200, or $850 per product.
In addition, we estimate that any necessary follow-on actions will
take about 114 work-hours and require parts costing $435,000, for a
cost of $444,690 per product. We have no way of determining the number
of aircraft that might need these actions.
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.
