Download as PDF Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Proposed Rules B1, B2, B3, C, D, and D1 helicopters that do not have a redesigned hold-down strap. AD 2014–02–05 corresponds with EASA AD 2009–0019, dated February 3, 2009. Withdrawal of the NPRM constitutes only such action and does not preclude the FAA from further rulemaking on this issue, nor does it commit the FAA to any course of action in the future. Request To Revise the Applicability of the NPRM The European Aviation Safety Agency (now European Union Aviation Safety Agency (EASA) and American Eurocopter, in consultation with Eurocopter, requested that the applicability of the NPRM be limited to helicopters modified by a Geneva center console supplemental type certificate (STC). The FAA acknowledges these comments to the NPRM. However, the FAA considers the requested change to the NPRM moot by this withdrawal. FAA’s Conclusions Upon further consideration, the FAA has determined that the NPRM does not adequately address the identified unsafe condition and is unnecessary due to other rulemaking. Accordingly, the NPRM is withdrawn. Regulatory Findings List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Withdrawal Accordingly, the notice of proposed rulemaking, Docket No. FAA–2007– 27495, which was published in the Federal Register on March 13, 2007 (72 FR 11297), is withdrawn. jbell on DSKJLSW7X2PROD with PROPOSALS ■ Issued on February 24, 2021.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0222, dated October 14, 2020 (EASA AD 2020–0222) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Airbus SAS Model A321– 211, –231, and –232 airplanes. This proposed AD was prompted by a report of false drill starts found around the latch hook mounting holes of certain door frames of the fuselage due to erroneous manufacturing processes. These false drill starts were found around the latch hook mounting holes on frames 16 and 66 of the left- and right-hand sides of forward and aft passenger doors 1 and 4. The FAA is proposing this AD to address damage from false drill starts, which could result in reduced structural integrity of the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2020–0222 describes procedures for a one-time detailed inspection of the area around the latch hook mounting holes of the forward and aft door frames to detect damage from false drill starts, and repair of any damage found. 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 2020–0222 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. Clarification of Compliance Times to Certain Proposed AD Requirements Although EASA AD 2020–0222 does not specifically state compliance times for the corrective actions required by paragraph (2) of EASA AD 2020–0222, paragraph (2) of EASA AD 2020–0222 does specify to accomplish applicable corrective actions within the compliance time as specified in Airbus Service Bulletin A320–53–1473, dated December 20, 2019. Airbus Service Bulletin A320–53–1473, dated December 20, 2019, specifies the compliance times for these actions are before further flight. Therefore, paragraph (g) of this proposed AD would require the corrective actions to be done before further flight. 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 2020–0222 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2020–0222 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 2020–0222 that is required for compliance with EASA AD 2020–0222 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0128 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 21 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 14 work-hours × $85 per hour = $1,190 ..................................................................................... $0 $1,190 $24,990 jbell on DSKJLSW7X2PROD with PROPOSALS * Table does not include estimated costs for reporting. The FAA estimates that it would take about 1 work-hour per product to comply with the proposed reporting requirement in this proposed AD. The average labor rate is $85 per hour. Based VerDate Sep<11>2014 16:28 Mar 05, 2021 Jkt 253001 on these figures, the FAA estimates the cost of reporting the inspection results on U.S. operators to be $1,785, or $85 per product. The FAA estimates the following costs to do any necessary on-condition PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 repairs 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 repairs: E:\FR\FM\08MRP1.SGM 08MRP1 Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Proposed Rules 13231 ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Up to 42 work-hours × $85 per hour = $3,570 (per door) ...................................................................................... * $0 Cost per product Up to $3,570. * The FAA has received no definitive data on which to base the parts cost estimates for the on-condition repairs 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 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 PROPOSALS Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this proposed AD is 2120– 0056. The paperwork cost associated with this proposed AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this proposed AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177–1524. 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 VerDate Sep<11>2014 17:32 Mar 05, 2021 Jkt 253001 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) Would not affect intrastate aviation in Alaska, and (3) Would 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.

(Type Certificate Previously Held by Agusta S.p.A.) Helicopters Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede airworthiness directive (AD) 2015–25–04 for Agusta S.p.A (now Leonardo S.p.a.) Model A109A and A109A II helicopters. AD 2015–25–04 requires inspecting the slider assembly pitch control (slider) for play and replacing the slider if the play exceeds certain limits. Since the FAA issued AD 2015–25–04, further investigation determined the play was caused by a manufacturing issue. This proposed AD would retain certain requirements of AD 2015–25–04, require replacing certain part-numbered sliders as a terminating action for the inspections, and prohibit installing the affected part on any helicopter.

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 A321-211, -231, and -232 airplanes. This 
proposed AD was prompted by a report of false drill starts found around 
the latch hook mounting holes of certain door frames of the fuselage 
due to erroneous manufacturing processes. This proposed AD would 
require a one-time inspection of the area around the latch hook 
mounting holes of the forward and aft door frames to detect damage from 
false drill starts, and repair if necessary, as specified in a European 
Union Aviation Safety Agency (EASA) AD, which is proposed for 
incorporation 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 April 22, 
2021.

11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this proposed AD.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated

[[Page 13230]]

as private, that you actually treat as private, and that is relevant or 
responsive to this NPRM, it is important that you clearly designate the 
submitted comments as CBI. Please mark each page of your submission 
containing CBI as ``PROPIN.'' The FAA will treat such marked 
submissions as confidential under the FOIA, and they will not be placed 
in the public docket of this NPRM. Submissions containing CBI should be 
sent to Sanjay Ralhan, Aerospace Engineer, Large Aircraft Section, 
International Validation Branch, FAA, 2200 South 216th St., Des Moines, 
WA 98198; telephone and fax 206-231-3223; email [email protected]. 
Any commentary that the FAA receives which is not specifically 
designated as CBI will be placed in the public docket for this 
rulemaking.

Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0222, dated October 14, 2020 
(EASA AD 2020-0222) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Airbus SAS Model A321-211, -231, and -232 airplanes.
    This proposed AD was prompted by a report of false drill starts 
found around the latch hook mounting holes of certain door frames of 
the fuselage due to erroneous manufacturing processes. These false 
drill starts were found around the latch hook mounting holes on frames 
16 and 66 of the left- and right-hand sides of forward and aft 
passenger doors 1 and 4.
    The FAA is proposing this AD to address damage from false drill 
starts, which could result in reduced structural integrity of the 
airplane. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0222 describes procedures for a one-time detailed 
inspection of the area around the latch hook mounting holes of the 
forward and aft door frames to detect damage from false drill starts, 
and repair of any damage found. 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 2020-0222 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this AD.

Clarification of Compliance Times to Certain Proposed AD Requirements

    Although EASA AD 2020-0222 does not specifically state compliance 
times for the corrective actions required by paragraph (2) of EASA AD 
2020-0222, paragraph (2) of EASA AD 2020-0222 does specify to 
accomplish applicable corrective actions within the compliance time as 
specified in Airbus Service Bulletin A320-53-1473, dated December 20, 
2019. Airbus Service Bulletin A320-53-1473, dated December 20, 2019, 
specifies the compliance times for these actions are before further 
flight. Therefore, paragraph (g) of this proposed AD would require the 
corrective actions to be done before further flight.

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 2020-0222 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0222 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 2020-0222 that is required for compliance with EASA AD 2020-
0222 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2021-0128 after the FAA 
final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 21 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                     Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
14 work-hours x $85 per hour = $1,190........................              $0           $1,190          $24,990
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    The FAA estimates that it would take about 1 work-hour per product 
to comply with the proposed reporting requirement in this proposed AD. 
The average labor rate is $85 per hour. Based on these figures, the FAA 
estimates the cost of reporting the inspection results on U.S. 
operators to be $1,785, or $85 per product.
    The FAA estimates the following costs to do any necessary on-
condition repairs 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 repairs:

[[Page 13231]]



                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
           Labor cost                Parts cost      Cost per  product
------------------------------------------------------------------------
Up to 42 work-hours x $85 per               * $0   Up to $3,570.
 hour = $3,570 (per door).
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the parts
  cost estimates for the on-condition repairs 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 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.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this proposed AD has 
been detailed in the Costs of Compliance section of this document and 
includes time for reviewing instructions, as well as completing and 
reviewing the collection of information. Therefore, all reporting 
associated with this proposed AD is mandatory. Comments concerning the 
accuracy of this burden and suggestions for reducing the burden should 
be directed to Information Collection Clearance Officer, Federal 
Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-
1524.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
