SUPPLEMENTARY INFORMATION: Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0083, dated April 3, 2020 (‘‘EASA AD 2020–0083’’) (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus SAS Model A330–202, –203, –223, –223F, –243, –243F, –302, –303, –323, –343, and –941 airplanes; and Model A340–313, –541, and –642 airplanes. 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 A330–202, –203, –223, –223F, –243, –243F, –302, –303, –323, –343, and –941 airplanes; and Model A340–313, –541, and –642 airplanes. The NPRM published in the Federal Register on May 6, 2020 (85 FR 26896). The NPRM was prompted by the results of laboratory tests on non-rechargeable lithium batteries installed in ELTs, which highlighted a lack of protection against currents of 28 volts DC or 115 volts AC that could lead to thermal runaway and a battery fire. The NPRM proposed to require modifying a certain ELT by installing a diode between the ELT and the terminal block, as specified in EASA AD 2020–0083. Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Allow Any Color and Width of Tape Delta Air Lines (DAL) requested that operators be allowed to use any color and width of reinforced silicon tape, instead of part number (P/N) ASNA51072503, to protect the wiring in the area where the diode is secured to the harness. The commenter explained that P/N ASNA51072503 is specified in Airbus Service Bulletin A330–25–3733 (‘‘Airbus Service Bulletin A330–25– 3733’’), and is for the 1-inch orange reinforced silicon tape under the ASNA5107 standard (which is an aerospace industry standard for a silicone rubber tape). The commenter requested approval to use any color and width of reinforced silicon tape meeting E:\FR\FM\08OCR1.SGM 08OCR1 Federal Register / Vol. 85, No. 196 / Thursday, October 8, 2020 / Rules and Regulations the specifications of the broader ASNA5107 standard. The commenter explained that the specified reinforced silicon tape has a shelf-life, and it would be beneficial to operators if they were given the flexibility to use any color and width of reinforced silicon tape if the reinforced silicon tape is needed to be replaced during maintenance. The FAA does not agree with the commenter’s request. The commenter did not provide sufficient justification for the use of any color and width of reinforced silicon tape meeting the specifications of the broader ASNA5107 standard. The FAA is not aware of the airworthiness quality of other reinforced silicon tapes under specification ASNA5107. Furthermore, all selfadhesive tapes under the ASNA5107 standard, and their alternatives, have limited shelf lives. The reinforced silicon tape having P/N ASNA51072503 is included in the parts kit specified in Airbus Service Bulletin A330–25–3733 and will be delivered to operators. Airbus, as the Design Approval Holder (DAH), may authorize using alternate materials, which may be included in revised Airbus service information. Operators may, however, request alternative methods of compliance to use reinforced silicone tape other than P/N ASNA51072503 by following the procedures specified in paragraph (i)(1) of this AD and demonstrating how this alternative addresses the unsafe condition. The FAA has not revised this AD in regard to this issue. Request To Allow an Alternative Continuity Check In addition, DAL requested and provided an option to replace Step 3.C.(h) specified in Airbus Service Bulletin A330–25–3733. The commenter explained that Step 3.C.(h) in Airbus Service Bulletin A330–25–3733 requires a continuity test of the modified wiring and provides no specific steps for this test other than referencing Electrical Standard Practices Manual (ESPM) section 20–52–21. The commenter noted that although this ESPM section does provide basic continuity procedures, it fails to provide a procedure for a wire with a diode installed. The FAA disagrees with the commenter’s request. The FAA has determined that the procedures described in ESPM section 20–52–21 provide an adequate method for performing a continuity test using a standard multimeter. When placing the multimeter probes in the correct position, the operator is instructed to refer to the wiring schematic within Airbus Service Bulletin A330–25–3733, which provides the necessary procedures for a wire with a diode installed. In addition, anode/cathode polarization is depicted on the diode’s housing. Furthermore, Airbus Service Bulletin A330–25–3733 specifies that after the wiring modification is done, a built-in test equipment (BITE) test of the ELT should be performed. The BITE test is also adequate to reveal an incorrectly installed diode. In addition, the commenter did not provide justification regarding how its proposed procedure would maintain the airworthiness of the airplane. Operators 63439 may, however, request alternative methods of compliance to replace Step 3.C.(h) specified in Airbus Service Bulletin A330–25–3733 by using the procedures described in paragraph (i)(1) of this AD and demonstrating how this alternative addresses the unsafe condition. The FAA has not changed this AD regarding this issue. Conclusion The FAA reviewed the relevant data, considered the comments 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 IBR Material Under 1 CFR Part 51 EASA AD 2020–0083 describes procedures for modifying a certain ELT by installing a diode between the ELT and the terminal block. 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 12 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 3 work-hours × $85 per hour = $255 .......................................................................................... $460 $715 $8,580 khammond on DSKJM1Z7X2PROD with RULES 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 individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in our 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 VerDate Sep<11>2014 16:24 Oct 07, 2020 Jkt 253001 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:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0083, dated April 3, 2020 
(``EASA AD 2020-0083'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus SAS Model A330-202, -203, -223, -223F, -
243, -243F, -302, -303, -323, -343, and -941 airplanes; and Model A340-
313, -541, and -642 airplanes.
    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 A330-202, -203, -223, -223F, -243, -243F, -302, -303, -323, -343, 
and -941 airplanes; and Model A340-313, -541, and -642 airplanes. The 
NPRM published in the Federal Register on May 6, 2020 (85 FR 26896). 
The NPRM was prompted by the results of laboratory tests on non-
rechargeable lithium batteries installed in ELTs, which highlighted a 
lack of protection against currents of 28 volts DC or 115 volts AC that 
could lead to thermal runaway and a battery fire. The NPRM proposed to 
require modifying a certain ELT by installing a diode between the ELT 
and the terminal block, as specified in EASA AD 2020-0083.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment.

Request To Allow Any Color and Width of Tape

    Delta Air Lines (DAL) requested that operators be allowed to use 
any color and width of reinforced silicon tape, instead of part number 
(P/N) ASNA51072503, to protect the wiring in the area where the diode 
is secured to the harness. The commenter explained that P/N 
ASNA51072503 is specified in Airbus Service Bulletin A330-25-3733 
(``Airbus Service Bulletin A330-25-3733''), and is for the 1-inch 
orange reinforced silicon tape under the ASNA5107 standard (which is an 
aerospace industry standard for a silicone rubber tape). The commenter 
requested approval to use any color and width of reinforced silicon 
tape meeting

[[Page 63439]]

the specifications of the broader ASNA5107 standard. The commenter 
explained that the specified reinforced silicon tape has a shelf-life, 
and it would be beneficial to operators if they were given the 
flexibility to use any color and width of reinforced silicon tape if 
the reinforced silicon tape is needed to be replaced during 
maintenance.
    The FAA does not agree with the commenter's request. The commenter 
did not provide sufficient justification for the use of any color and 
width of reinforced silicon tape meeting the specifications of the 
broader ASNA5107 standard. The FAA is not aware of the airworthiness 
quality of other reinforced silicon tapes under specification ASNA5107. 
Furthermore, all self-adhesive tapes under the ASNA5107 standard, and 
their alternatives, have limited shelf lives. The reinforced silicon 
tape having P/N ASNA51072503 is included in the parts kit specified in 
Airbus Service Bulletin A330-25-3733 and will be delivered to 
operators. Airbus, as the Design Approval Holder (DAH), may authorize 
using alternate materials, which may be included in revised Airbus 
service information. Operators may, however, request alternative 
methods of compliance to use reinforced silicone tape other than P/N 
ASNA51072503 by following the procedures specified in paragraph (i)(1) 
of this AD and demonstrating how this alternative addresses the unsafe 
condition. The FAA has not revised this AD in regard to this issue.

Request To Allow an Alternative Continuity Check

    In addition, DAL requested and provided an option to replace Step 
3.C.(h) specified in Airbus Service Bulletin A330-25-3733. The 
commenter explained that Step 3.C.(h) in Airbus Service Bulletin A330-
25-3733 requires a continuity test of the modified wiring and provides 
no specific steps for this test other than referencing Electrical 
Standard Practices Manual (ESPM) section 20-52-21. The commenter noted 
that although this ESPM section does provide basic continuity 
procedures, it fails to provide a procedure for a wire with a diode 
installed.
    The FAA disagrees with the commenter's request. The FAA has 
determined that the procedures described in ESPM section 20-52-21 
provide an adequate method for performing a continuity test using a 
standard multimeter. When placing the multimeter probes in the correct 
position, the operator is instructed to refer to the wiring schematic 
within Airbus Service Bulletin A330-25-3733, which provides the 
necessary procedures for a wire with a diode installed. In addition, 
anode/cathode polarization is depicted on the diode's housing. 
Furthermore, Airbus Service Bulletin A330-25-3733 specifies that after 
the wiring modification is done, a built-in test equipment (BITE) test 
of the ELT should be performed. The BITE test is also adequate to 
reveal an incorrectly installed diode.
    In addition, the commenter did not provide justification regarding 
how its proposed procedure would maintain the airworthiness of the 
airplane. Operators may, however, request alternative methods of 
compliance to replace Step 3.C.(h) specified in Airbus Service Bulletin 
A330-25-3733 by using the procedures described in paragraph (i)(1) of 
this AD and demonstrating how this alternative addresses the unsafe 
condition. The FAA has not changed this AD regarding this issue.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
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.

    EASA AD 2020-0083 describes procedures for modifying a certain ELT 
by installing a diode between the ELT and the terminal block. 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 12 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
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255...........................            $460             $715           $8,580
----------------------------------------------------------------------------------------------------------------

    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 individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in our 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

[[Page 63440]]

    (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.
