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.

(e) Reason

    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: 9-ANM-116-AMOC-REQUESTS@faa.gov. 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,

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.
