SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0255, dated November 13, 2020 (EASA AD 2020–0255) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Airbus SAS Model A330–201, –202, –203, –223, –243, –301, –302, –303, –321, –322, –323, –341, –342, and –343 airplanes; and Model A340–211, –212, –213, –311, –312, –313, –541, –542, –642, and –643 airplanes. Model A340–542 and A340– 643 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. E:\FR\FM\11JNR1.SGM 11JNR1 31096 Federal Register / Vol. 86, No. 111 / Friday, June 11, 2021 / Rules and Regulations The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A330–200, A330–300, A340–200, A340– 300, A340–500, and A340–600 series airplanes. The NPRM published in the Federal Register on March 11, 2021 (86 FR 13836). The NPRM was prompted by reports that, for certain LDMCR units, the connection of a certain halon outlet tube to the outlet of a certain fire extinguisher bottle may be incorrect. The NPRM proposed to require replacing each affected halon outlet tube with a flexible hose, as specified in EASA AD 2020–0255. The FAA is issuing this AD to address the possible incorrect connection of the halon outlet tube as described previously, which, in case of a fire inside the LDMCR, could lead to disconnection of the tube, possibly resulting in reduced concentration of fire suppressing agent at any location inside the LDMCR. See the MCAI for additional background information. • Do not add any additional burden upon the public than was already proposed in the NPRM. Comments Related Service Information Under 1 CFR Part 51 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), stated that it supports 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: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and EASA AD 2020–0255 describes procedures for replacing each affected halon outlet tube in the LDMCR with a flexible hose. 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 123 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .......................................................................................... $(*) $340 $41,820 * The FAA has received no definitive data on which to base the parts cost estimates for the replacements specified in this AD. 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. jbell on DSKJLSW7X2PROD with RULES 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.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0255, dated November 13, 2020 
(EASA AD 2020-0255) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Airbus SAS Model A330-201, -202, -203, -223, -243, -301, -
302, -303, -321, -322, -323, -341, -342, and -343 airplanes; and Model 
A340-211, -212, -213, -311, -312, -313, -541, -542, -642, and -643 
airplanes. Model A340-542 and A340-643 airplanes are not certificated 
by the FAA and are not included on the U.S. type certificate data 
sheet; this AD therefore does not include those airplanes in the 
applicability.

[[Page 31096]]

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Airbus SAS 
Model A330-200, A330-300, A340-200, A340-300, A340-500, and A340-600 
series airplanes. The NPRM published in the Federal Register on March 
11, 2021 (86 FR 13836). The NPRM was prompted by reports that, for 
certain LDMCR units, the connection of a certain halon outlet tube to 
the outlet of a certain fire extinguisher bottle may be incorrect. The 
NPRM proposed to require replacing each affected halon outlet tube with 
a flexible hose, as specified in EASA AD 2020-0255.
    The FAA is issuing this AD to address the possible incorrect 
connection of the halon outlet tube as described previously, which, in 
case of a fire inside the LDMCR, could lead to disconnection of the 
tube, possibly resulting in reduced concentration of fire suppressing 
agent at any location inside the LDMCR. 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), stated 
that it supports 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:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     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 2020-0255 describes procedures for replacing each affected 
halon outlet tube in the LDMCR with a flexible hose. 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 123 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

* The FAA has received no definitive data on which to base the parts cost estimates for the replacements
  specified in this AD.

    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.
    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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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:
2021-11-20 Airbus SAS: Amendment 39-21582; Docket No. FAA-2021-0140; 
Project Identifier MCAI-2020-01531-T.

(a) Effective Date

    This airworthiness directive (AD) is effective July 16, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Airbus SAS airplanes specified in 
paragraphs (c)(1) through (6) of this AD, certificated in any 
category, as identified in European Union Aviation Safety Agency 
(EASA) AD 2020-0255, dated November 13, 2020 (EASA AD 2020-0255).
    (1) Model A330-201, -202, -203, -223, and -243 airplanes.
    (2) Model A330-301, -302, -303, -321, -322, -323, -341, -342, 
and -343 airplanes.
    (3) Model A340-211, -212, and -213 airplanes.
    (4) Model A340-311, -312, and -313 airplanes.

[[Page 31097]]

    (5) Model A340-541 airplanes.
    (6) Model A340-642 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 25, Equipment/
furnishings.

(e) Reason

    This AD was prompted by reports that, for certain lower deck 
mobile crew rest (LDMCR) units, the connection of a certain halon 
outlet tube to the outlet of a certain fire extinguisher bottle may 
be incorrect. The FAA is issuing this AD to address this condition, 
which, in case of a fire inside the LDMCR, could lead to 
disconnection of the tube, possibly resulting in reduced 
concentration of fire suppressing agent at any location inside the 
LDMCR.

(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 2020-0255.

(h) Exceptions to EASA AD 2020-0255

    (1) Where EASA AD 2020-0255 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2020-0255 does not apply 
to this AD.

(i) No Reporting Requirement

    Although the service information referenced in EASA AD 2020-0255 
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: [email protected]. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
responsible Flight Standards 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): Except as required by 
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.
