Airworthiness Directives; Airbus SAS Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2016-12-
09, which applied to certain Airbus Model A330-200, -200 Freighter, and
-300 series airplanes; and Model A340-200 and -300 series airplanes. AD
2016-12-09 requirements included removing existing and installing new
fasteners, inspecting for and, if necessary, repairing cracking. This
new AD requires repetitive inspections of the fastener holes at a
certain frame and applicable on-condition actions, and, for certain
airplanes, requires a modification, as specified in European Union
Aviation Safety Agency (EASA) ADs, which are incorporated by reference.
Also as specified in the EASA ADs, this AD also provide an optional
terminating action for certain airplanes, which terminates the
inspections. This AD was prompted by reports that cracks were found on
an adjacent hole of certain frames of the center wing box (CWB) and a
determination that the compliance time specified in AD 2016-12-09 for
the modification of the inside CWB must be revised. The FAA is issuing
this AD to address the unsafe condition on these products.
DATES: This AD is effective October 22, 2019.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 22,
2019.

SUPPLEMENTARY INFORMATION:
Discussion
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2018-0249R1, dated July 31, 2019;
corrected August 2, 2019 (``EASA AD 2018-0249R1'') (also referred to as
the Mandatory Continuing Airworthiness Information, or ``the MCAI''),
to correct an unsafe condition for certain Airbus SAS Model A330-200, -
200 Freighter, and -300 series airplanes; and Model A340-200 and -300
series airplanes.
The FAA issued a supplemental notice of proposed rulemaking (SNPRM)
to amend 14 CFR part 39 to supersede AD 2016-12-09, Amendment 39-18558
(81 FR 38573, June 14, 2016) (``AD 2016-12-09''). AD 2016-12-09 applied
to certain Airbus Model A330-200, -200 Freighter, and -300 series
airplanes, and Model A340-200 and -300 series airplanes. The SNPRM
published in the Federal Register on May 23, 2019 (84 FR 23742) (``the
SNPRM''). The FAA preceded the SNPRM with a notice of proposed
rulemaking (NPRM) that published in the Federal Register on February
26, 2018 (83 FR 8201) (``the NPRM''). The NPRM was prompted by reports
that cracks were found on an adjacent hole of certain frames of the
CWB. The NPRM proposed to require repetitive inspections of the
fastener holes at frame (FR) 40, and, for certain airplanes, proposed
to require a modification. The NPRM also proposed to provide an
optional terminating action for certain airplanes, which terminates the
inspections. The SNPRM proposed to revise the compliance time for the
modification of the inside CWB. The FAA is issuing this AD to address
cracking of certain holes of certain frames of the CWB, which could
affect the structural integrity of the airplane.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the SNPRM
or on the determination of the cost to the public.
New EASA AD
In the SNPRM, the FAA referred to EASA AD 2018-0249, dated November
16, 2018 (``EASA AD 2018-0249''). Since the SNPRM was issued, EASA
issued EASA AD 2018-0249R1, which clarifies the conditions for certain
actions and removes paragraphs that are not necessary.
The FAA determined that no additional work is required for
airplanes that have accomplished the actions as required by EASA AD
2018-0249. Therefore, the FAA has revised all applicable sections in
this final rule to also specify EASA AD 2018-0249R1.
Change Made to This Final Rule
The SNPRM included a terminating action paragraph for AD 2016-12-09
(paragraph (j) of the proposed AD). However, AD 2016-12-09 is
superseded by this AD; therefore, that terminating action paragraph is
not needed. We have removed paragraph (j) of the proposed AD from this
AD.
[[Page 48784]]
Conclusion
The FAA reviewed the relevant data 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:
<bullet> Are consistent with the intent that was proposed in the
SNPRM for addressing the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the SNPRM.
The FAA 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 ADs 2018-0249 and 2018-0249R1 describe procedures for
repetitive inspections of the fastener holes at the FR40 vertical web
of the affected CWB lower panel area for any cracking, and on-condition
actions; modification of the inside CWB and an optional terminating
action (modification of fastener holes by cold-working), which
terminates the repetitive inspections. On-condition actions include
installing new fasteners, additional inspections, repair, and
modification. These documents are distinct since AD 2018-0249R1
clarifies the conditions for certain actions, removes paragraphs that
are not necessary, and provides credit for certain alternative methods
of compliance. 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 103 airplanes of U.S.
registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Retained actions from AD 2016-12-09 Up to 155 work-hours x $0........................... Up to $13,175............... Up to $1,357,025.
$85 per hour = Up to
$13,175.
New actions........................ Up to 145 work-hours x Up to $650................... Up to $12,975............... Up to $1,336,425.
$85 per hour = Up to
$12,325.
--------------------------------------------------------------------------------------------------------------------------------------------------------
Estimated Costs for Optional Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Up to 145 work-hours x $85 per hour = Up Up to $621........................ Up to $12,946.
to $12,325.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions 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 these on-condition actions:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Up to 105 work-hours x $85 per hour = Up Up to $22,488..................... Up to $31,413.
to $8,925.
----------------------------------------------------------------------------------------------------------------
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
The FAA has 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) 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.
