Airworthiness Directives; Airbus SAS Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus SAS Model A330-200 Freighter, -200, and -300 series
airplanes; and certain Airbus SAS Model A340-200, -300, -500, and -600
series airplanes. This AD was prompted by a determination that certain
wing slat tracks that were inadvertently indicated as eligible for
installation on all Model A330 and A340 series airplanes are unable to
sustain the ultimate loads relative to the weight variant of certain
airplane configurations. This AD requires identifying affected parts,
inspecting for and repairing cracks, and replacing affected parts with
serviceable parts, as specified in a European Aviation Safety Agency
(EASA) AD, which is incorporated by reference. The FAA is issuing this
AD to address the unsafe condition on these products.
DATES: This AD is effective October 15, 2019.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 15,
2019.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Airbus SAS
Model A330-200 Freighter, -200 and -300 series airplanes; and certain
Airbus SAS Model A340-200, -300, -500, and -600 series airplanes. The
NPRM published in the Federal Register on May 8, 2019 (84 FR 20057).
The NPRM was prompted by a determination that certain wing slat tracks
that were inadvertently indicated as eligible for installation on all
Model A330 and A340 series airplanes are unable to sustain the ultimate
loads relative to the weight variant of certain airplane
configurations. The NPRM proposed to require inspecting any affected
part for cracking, and replacing with a serviceable part.
The FAA is issuing this AD to address installation of affected
parts, which could result in slat detachment in flight and consequent
reduced control of the airplane.
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2019-0026, dated February 4, 2019
(``EASA AD 2019-0026'') (also referred to as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Airbus SAS Model A330-200 Freighter, -200, and -
300 series airplanes; and certain Airbus SAS Model A340-200, -300, -
500, and -600 series airplanes. The MCAI states:
It was recently determined that, since June 2010, the affected
parts were inadvertently indicated as eligible for installation on
all A330 and A340 aeroplanes in the applicable Illustrated Part
Catalogue (IPC), although in fact, those parts are not valid for
some aeroplane configurations (weight variants), because they are
unable to sustain ultimate load. Investigation demonstrated that
affected parts were never delivered as spare part. However, it
cannot be excluded that an affected part was removed in-service from
an aeroplane and installed on another.
This condition, if not detected and corrected, could lead to
slat detachment in flight, possibly resulting in reduced control of
the aeroplane.
To address this potential unsafe condition, Airbus published the
applicable SB [service bulletin] to provide instructions to identify
affected parts, and instructions to inspect [for cracking of] those
affected parts found installed.
For the reasons described above, this [EASA] AD requires a one-
time detailed (DET) and special detailed inspection (SDI) of the aft
lug of each affected part and replacement of each affected part.
This [EASA] AD also prohibits installation of affected parts.
You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0320.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Request To Include Additional Exceptions to the MCAI
American Airlines (AAL) asked that an airplane records review for
the affected part identification be an approved method of compliance in
the proposed AD. AAL stated that its maintenance records indicate that
no affected #10 slat track was installed in production, or has been
installed since aircraft delivery.
The FAA agrees with the commenter's request. The FAA has added
paragraph (h)(2) to this AD to allow a review of airplane maintenance
records in lieu of the inspections for the part numbers of the wing
slat tracks at the #10 position. Subsequent paragraphs have been
redesignated accordingly.
AAL also asked that in cases where the slat track part number is
not identifiable, instructions be provided in the proposed AD to
specify a range for the slat track measured thickness used to identify
affected parts. AAL stated that Airbus Service Bulletin A330-57-3144,
dated November 12, 2018, which is referenced in EASA AD 2019-0026,
specifies that if the slat track part number is not identifiable, the
upper thickness of the aft lug must be measured, and if the dimension
is ``10.80 mm,'' the part is an affected slat track and must be
replaced. AAL questioned whether a slat track with a measurement other
than 10.80 mm would be affected. Therefore, AAL requested that Airbus
provide a specific tolerance range that would require further
inspection and ultimate replacement. AAL stated that Airbus provided a
range of between 10.763 mm and 11.275 mm for the part to be an affected
slat track, which will be added to the next revision of the referenced
service bulletin.
The FAA agrees with the commenter's request for the reasons
provided. Paragraph (h)(3) has been added to this AD to specify the
measured dimension range of 10.763 mm through 11.275 mm inclusive for
an affected part. Subsequent paragraphs have been redesignated
accordingly.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule with the changes described previously
and minor editorial changes. The FAA has determined that these minor
changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
The FAA has also determined that these changes will not increase
the economic burden on any operator or increase the scope of this final
rule.
Related IBR Material Under 1 CFR Part 51
EASA AD 2019-0026 describes procedures for one-time detailed and
special detailed (high frequency eddy current) inspections for cracking
of the aft lug of each affected wing slat track (including an
inspection to first determine if an affected slat track is installed),
and replacement of any affected part with a serviceable part. This
material 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
The FAA estimates that this AD affects 104 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 47409]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
7 work-hours x $85 per hour = $595........................... $0 $595 $61,880
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:
Estimated Costs of On-Condition Action
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
8 work-hours x $85 per hour = $680.... $0 $680
------------------------------------------------------------------------
According to the manufacturer, some or all of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected individuals. The FAA does not control warranty coverage for
affected individuals. As a result, the FAA has included all known costs
in the cost estimate.
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.
The FAA is 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.
Regulatory Findings
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) Will not affect intrastate aviation in Alaska, and
(3) 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.

(e) Reason
This AD was prompted by a determination that certain wing slat
tracks that had been inadvertently indicated as eligible for
installation on all Model A330 and A340 series airplanes are unable
to sustain the ultimate loads relative to the weight variant of
certain airplane configurations. The FAA is issuing this AD to
address installation of affected parts, which could result in slat
detachment in flight and consequent reduced control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, EASA AD 2019-0026.
(h) Exceptions to EASA AD 2019-0026
(1) For purposes of determining compliance with the requirements
of this AD:
[[Page 47410]]
Where EASA AD 2019-0026 refers to its effective date, this AD
requires using the effective date of this AD.
(2) Where EASA AD 2019-0026 requires inspecting to determine the
part number of the wing slat tracks at the #10 position, this AD
allows a review of airplane maintenance records in lieu of the
inspection if the part number can be conclusively determined from
that review.
(3) EASA AD 2019-0026 refers to Airbus Service Bulletin A330-57-
3144, dated November 12, 2018, which specifies that if the slat
track part number is not identifiable, the upper thickness of the
aft lug must be measured, and if the dimension is 10.80 millimeters
(mm), it is an affected part and must be replaced. For this AD, the
affected part dimensions range from 10.763 mm through 11.275 mm
inclusive.
(4) The ``Remarks'' section of EASA AD 2019-0026 does not apply
to this AD.
(i) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Section, Transport Standards Branch, FAA, has the
authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
send your request to your principal inspector or local Flight
Standards District Office, as appropriate. If sending information
directly to the International Section, send it to the attention of
the person identified in paragraph (j) of this AD. Information may
be emailed to: [email protected]. Before using any
approved AMOC, notify your appropriate principal inspector, or
lacking a principal inspector, the manager of the local flight
standards district office/certificate holding district office.
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain instructions from a manufacturer, the instructions must be
accomplished using a method approved by the Manager, International
Section, Transport Standards Branch, FAA; or EASA; or Airbus SAS's
EASA Design Organization Approval (DOA). If approved by the DOA, the
approval must include the DOA-authorized signature.
(3) Required for Compliance (RC): For any service information
referenced in EASA AD 2019-0026 that contains RC procedures and
tests: Except as required by paragraph (i)(2) of this AD, RC
procedures and tests must be done to comply with this AD; any
procedures or tests that are not identified as RC are recommended.
Those procedures and tests that are not identified as RC may be
deviated from using accepted methods in accordance with the
operator's maintenance or inspection program without obtaining
approval of an AMOC, provided the procedures and tests identified as
RC can be done and the airplane can be put back in an airworthy
condition. Any substitutions or changes to procedures or tests
identified as RC require approval of an AMOC.
