SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0035, dated January 25, 2021
(EASA AD 2021-0035) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all Airbus SAS Model A330-841 and -941 airplanes.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Airbus SAS Model
A330-841 and -941 airplanes. The NPRM published in the Federal Register
on May 10, 2021 (86 FR 24790). The NPRM was prompted by reports of
missing or disbonded pressure seals on two TR translating cowls. The
NPRM proposed to require a one-time inspection of each TR for damage,
seal bonding rework, and replacement of translating cowl pressure seals
if necessary, as specified in EASA AD 2021-0035.
The FAA is issuing this AD to address missing or disbonded TR
translating cowl seal segments. In a case where all seal segments were
missing, this condition, if not addressed, could lead to loss of thrust
at maximum continuous thrust or at takeoff/go-around, possibly
resulting in substantially reduced performance of the airplane. See the
MCAI for additional background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA has considered the comment
received. The Air Line Pilots Association, International, (ALPA)
indicated its support for the NPRM.
Conclusion
The FAA reviewed the relevant data, considered the comment
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for minor
editorial changes. The FAA has determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0035 describes procedures for inspecting each TR for
damage (including tears, cracks, unwanted sealant on the contact
surface, missing pieces, worn-out seals, or glass or ceramic ply that
is not impacted), reworking the pressure seal bonding, and replacing
damaged translating cowl pressure seals.
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 8 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
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 (per thrust reverser)..... $0 $595 $4,760
----------------------------------------------------------------------------------------------------------------
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 these on-condition actions:
Estimated Costs of On-Condition Action
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
22 work-hours x $85 per hour = $1,870 $42,268 $44,138
(per thrust reverser)................
------------------------------------------------------------------------
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 operators. The FAA does not control warranty coverage for
affected operators. 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
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.
[[Page 42691]]
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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2021-15-13 Airbus SAS: Amendment 39-21660; Docket No. FAA-2021-0349;
Project Identifier MCAI-2021-00103-T.
(a) Effective Date
This airworthiness directive (AD) is effective September 9,
2021.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Airbus SAS Model A330-841 and -941
airplanes, certificated in any category.

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, European Union Aviation Safety Agency (EASA) AD
2021-0035, dated January 25, 2021 (EASA AD 2021-0035).
(h) Exceptions to EASA AD 2021-0035
(1) Where EASA AD 2021-0035 refers to its effective date, this
AD requires using the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2021-0035 does not apply
to this AD.
(i) No Reporting Requirement
Although the service information referenced in EASA AD 2021-0035
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 responsible Flight
Standards 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) of this
AD. Information may be emailed to: <a href="/cdn-cgi/l/email-protection#cff6e28e999ce28e869de2f8fcffe28e82808c8fa9aeaee1a8a0b9"><span class="__cf_email__" data-cfemail="b0899df1e6e39df1f9e29d8783809df1fdfff3f0d6d1d19ed7dfc6">[email protected]</span></a>.

paragraph (j)(2) of this AD, if any service information contains
procedures or tests that are identified as RC, those 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.
