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 A330-200 and A330-300 series airplanes,
and all Model A340-200 and A340-300 series airplanes. This proposed AD
was prompted by reports of hydraulic system failure due to fatigue
failure of the screws attaching the manual valve to the ground service
manifold (GSM). This proposed AD would require, for certain GSMs,
repetitive replacement of the hydraulic system GSM manual valve
attachment screws having certain part numbers; and, for certain other
GSMs with certain screws installed, replacement of those screws, 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 September
14, 2020.

Discussion
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0093, dated April 24, 2020
(``EASA AD 2020-0093'') (also referred to as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Airbus SAS Model A330-200 and A330-300 series
airplanes, and all Model A340-200 and A340-300 series airplanes.
This proposed AD was prompted by reports of hydraulic system
failure due to the fatigue failure of the screws attaching the manual
valve to the GSM. The FAA is proposing this AD to address the failure
of hydraulic system manual valve attachment screws. This condition, if
not addressed, could lead to the loss of one or more hydraulic systems
and damage to surrounding structure and components, possibly resulting
in reduced control of the airplane, or injury to maintenance staff
working in the main landing gear bay. See the MCAI for additional
background information.
Related IBR Material Under 1 CFR Part 51
EASA AD 2020-0093 describes procedures for replacement of the
hydraulic system GSM manual valve attachment screws. For GSMs with part
number (P/N) 70902-3 or P/N 70902-4 installed with screws having P/N
NAS1101-3H8, EASA AD 2020-0093 describes procedures for repetitive
replacement of those screws with new screws having P/N NAS1101-3H8. For
GSMs with P/N 70902-5 installed with screws having P/N NAS1101-3H8,
EASA AD 2020-0093 describes procedures for replacement of those screws
with new bolts having P/N EWB0420D-3H-3 or four new screws having P/N
NAS1101-3H8; if new screws are installed, EASA AD 2020-0093 describes
procedures for replacing them with new bolts having P/N EWB0420D-3H-3
before the screws exceed 10,000 flight cycles since installation on an
airplane. EASA AD 2020-0093 also describes an optional terminating
modification (replacement of all affected GSMs), which would terminate
the repetitive replacements of the attachment screws.
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
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 2020-0093 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 2020-0093
will be incorporated by reference in the FAA final rule. This proposed
AD would, therefore, require compliance with EASA AD 2020-0093 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 2020-0093 that is required for compliance with EASA AD 2020-
0093 will be available on the internet at https://www.regulations.gov
by searching for and locating Docket No. FAA-2020-0674 after the FAA
final rule is published.
Costs of Compliance
The FAA estimates that this proposed AD affects 107 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
7 work-hours x $85 per hour = $595 per $0* $595 per cycle............ $63,665 per cycle.
cycle.
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency to provide parts cost estimates for the
required actions specified in this proposed AD.
[[Page 46014]]
Estimated Costs for Optional Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
10 work-hours x $85 per hour = $850... $0* $850
------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency
to provide parts cost estimates for the optional actions specified in
this proposed AD.
According to the manufacturer, some or all of the costs of this
proposed 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.
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.

This AD was prompted by reports of hydraulic system failure due
to fatigue failure of the screws attaching the manual valve to the
ground service manifold (GSM). The FAA is issuing this AD to address
the failure of hydraulic system manual valve attachment screws. This
condition, if not addressed, could lead to the loss of one or more
hydraulic systems and damage to surrounding structure and
components, possibly resulting in reduced control of the airplane,
or injury to maintenance staff working in the main landing gear bay.
(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 2020-0093.
(h) Exceptions to EASA AD 2020-0093
(1) Where EASA AD 2020-0093 refers to its effective date or to
``the effective date of EASA AD 2019-0314,'' this AD requires using
the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2020-0093 does not apply
to this AD.
(3) Where EASA AD 2020-0093 specifies to comply with ``the
instructions of the AOT,'' and ``the AOT'' specifies that ``the
accomplishment instructions marked as Required for Compliance (RC)
must be done'' this AD requires compliance with ``paragraph 4.4.2.,
Accomplishment Instructions, of the AOT'' only.
(i) No Reporting Requirement
Although the service information referenced in EASA AD 2020-0093
specifies to submit certain information to the manufacturer, this AD
does not include that requirement.
(j) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Large Aircraft Section, International Validation 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 Large Aircraft Section, International Validation
Branch, send it to the attention of the person identified in
paragraph (k)(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, Large Aircraft
Section,
[[Page 46015]]
International Validation 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 2020-0093 that contains RC procedures and
tests: Except as required by paragraphs (h)(3) and (j)(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.
