RIN 2120-AA64
Airworthiness Directives; Airbus SAS Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Airbus SAS Model A318-111, -112, -121, and -122 airplanes;
Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes;
Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and
Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes.
This proposed AD was prompted by reports of fatigue cracks on
continuity fittings at the lower framing of the front windshield on
airplanes on which a certain production modification has been embodied.
Additional analysis showed that certain certification requirements for
damage tolerance and fatigue are not met on airplanes in a certain
post-production modification configuration. This proposed AD would
require repetitive high frequency eddy current (HFEC) inspections of
the central node windshield area for cracking, and applicable
corrective actions if cracking is found, as specified in a European
Union Aviation Safety Agency (EASA) AD, which will be incorporated by
reference. The FAA is proposing this AD to address the unsafe condition
on these products.
DATES: The FAA must receive comments on this proposed AD by May 4,
2020.

Discussion
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0005, dated January 13, 2020
(``EASA AD 2020-0005'') (also referred to as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Airbus SAS Model A318-111, -112, -121, and -122
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133
airplanes; Model A320-211, -212, -214, -215, -216, -231, -232, and -233
airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and
-232 airplanes. Model A320-215 airplanes are not certified by the FAA
and are not included on the U.S. type certificate data sheet; this
proposed AD therefore does not include those airplanes in the
applicability.
This proposed AD was prompted by reports of fatigue cracks on
continuity fittings at the lower framing of the front windshield on
airplanes on which Airbus Production Modification 22058 (which is
included in Airbus Modification 21999) has been embodied. Additional
analysis showed that certain certification requirements for damage
tolerance and fatigue are not met on airplanes in a post-production
Modification 22058 configuration. The FAA is proposing this AD to
address this condition, which could lead to failure of the continuity
fittings at the lower node of the windshield central frame, possibly
resulting in decompression of the airplane and injury to occupants. See
the MCAI for additional background information.
Related IBR Material Under 1 CFR part 51
EASA AD 2020-0005 describes procedures for repetitive HFEC
inspections of the central node windshield area for cracking, and
applicable corrective actions if cracking is found. The corrective
actions include modification or repair. 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.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
[[Page 16012]]
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
referenced above. The FAA is proposing this AD because the FAA
evaluated all the relevant information and determined the unsafe
condition described previously is likely to exist or develop in other
products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in EASA AD 2020-0005 described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA initially worked with Airbus and EASA to develop a
process to use certain EASA ADs as the primary source of information
for compliance with requirements for corresponding FAA ADs. The FAA has
since coordinated with other manufacturers and civil aviation
authorities (CAAs) to use this process. As a result, EASA AD 2020-0005
will be incorporated by reference in the FAA final rule. This proposed
AD would, therefore, require compliance with EASA AD 2020-0005 in its
entirety, through that incorporation, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Using common terms that are the same as the heading of a particular
section in the EASA AD does not mean that operators need comply only
with that section. For example, where the AD requirement refers to
``all required actions and compliance times,'' compliance with this AD
requirement is not limited to the section titled ``Required Action(s)
and Compliance Time(s)'' in the EASA AD. Service information specified
in EASA AD 2020-0005 that is required for compliance with EASA AD 2020-
0005 will be available on the internet at https://www.regulations.gov
by searching for and locating Docket No. FAA-2020-0201 after the FAA
final rule is published.
Explanation of Note 1 of EASA AD 2020-0005
Note 1 of EASA AD 2020-0005 states that, for certain airplanes, no
further action is required by that AD up to the ``Publication
Trigger.'' The ``Publication Trigger'' is the operation limit for the
affected airplanes, which is specified in the Airbus A318/A319/A320/
A321 Airworthiness Limitations Section (ALS) Part 2-Damage Tolerant
Airworthiness Limitation Items (DT-ALI), Revision 07, dated June 13,
2018, (which is mandated by AD 2019-23-01, Amendment 39-19794 (84 FR
66579, December 5, 2019)). Airbus A318/A319/A320/A321 Airworthiness
Limitations Section (ALS) Part 2-Damage Tolerant Airworthiness
Limitation Items (DT-ALI), Revision 07, dated June 13, 2018, requires
operators to contact Airbus for further instructions before they exceed
the operation limit referenced as ``Publication Trigger.''
Costs of Compliance
The FAA estimates that this proposed AD affects 1,203 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
19 work-hours x $85 per hour = $1,615........................ $0 $1,615 $1,942,845
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.
The FAA estimates that it would take about 1 work-hour per product
to comply with the proposed reporting requirement in this proposed AD.
The average labor rate is $85 per hour. Based on these figures, the FAA
estimates the cost of reporting the inspection results on U.S.
operators to be $102,255, or $85 per product.
The FAA estimates the following costs to do any necessary on-
condition modifications 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 modifications:
Estimated Costs of On-Condition Modifications *
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
1,122 work-hours x $85 per hour = $316,043 $411,413
$95,370..............................
------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency
to provide cost estimates for the on-condition repairs specified in
this proposed AD.
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 proposed AD
is 2120-0056. The paperwork cost associated with this proposed 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 proposed AD is mandatory. Comments concerning the
accuracy of this burden and suggestions for reducing the burden should
be directed to Information Collection Clearance Officer, Federal
Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-
1524.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue
[[Page 16013]]
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.
Regulatory Findings
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(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.
List of Subjects in 14 CFR Part 39

(e) Reason
This AD was prompted by reports of fatigue cracks on continuity
fittings at the lower framing of the front windshield on airplanes
on which Airbus Production Modification 22058 (which is included in
Airbus Modification 21999) has been embodied. Additional analysis
showed that certain certification requirements for damage tolerance
and fatigue are not met on airplanes in a post-production
Modification 22058 configuration. The FAA is issuing this AD to
address this condition, which could lead to failure of the
continuity fittings at the lower node of the windshield central
frame, possibly resulting in decompression of the airplane and
injury to occupants.
(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 2020-0005.
(h) Exceptions to EASA AD 2020-0005
(1) Where EASA AD 2020-0005 refers to its effective date, this
AD requires using the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2020-0005 does not apply
to this AD.
(3) Paragraph (8) of EASA AD 2020-0005 specifies to report
inspection results to Airbus within a certain compliance time. For
this AD, report inspection results at the applicable time specified
in paragraph (h)(3)(i) or (ii) of this AD.
(i) If the inspection was done on or after the effective date of
this AD: Submit the report within 90 days after the inspection.
(ii) If the inspection was done before the effective date of
this AD: Submit the report within 90 days after the effective date
of 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)(2) 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 2020-0005 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.
(4) Paperwork Reduction Act Burden Statement: A federal agency
may not conduct or sponsor, and a person is not required to respond
to, nor shall a person be subject to a 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 OMB Control Number
for this information collection is 2120-0056. Public reporting for
this collection of information is estimated to be approximately 1
hour per response, including the time for reviewing instructions,
searching existing data sources, gathering and maintaining the data
needed, and completing and reviewing the collection of information.
All responses to this collection of information are mandatory as
required by this AD; the nature and extent of confidentiality to be
provided, if any. Send comments regarding this burden estimate or
any other aspect of this collection of information, including
