ACTION: Notice of proposed rulemaking (NPRM). jspears on DSK121TN23PROD with PROPOSALS1 AGENCY: The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes; Airbus SAS Model A300 B4– 600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called SUMMARY: VerDate Sep<11>2014 16:54 Oct 05, 2021 Jkt 256001 Model A300–600 series airplanes); and Airbus SAS Model A310 series airplanes. This proposed AD was prompted by reports of incorrect installation of the fire shut-off valves (FSOV) actuator, which was found to rotate around its pivot axis. This proposed AD would require a one-time detailed inspection of the FSOV actuator for rotation around its pivot axis, and replacement 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. The FAA must receive comments on this proposed AD by November 22, 2021.

Any commentary that the FAA E:\FR\FM\06OCP1.SGM 06OCP1 Federal Register / Vol. 86, No. 191 / Wednesday, October 6, 2021 / Proposed Rules receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0106, dated April 15, 2021 (EASA AD 2021– 0106) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus SAS Model A300, A310, A300–600 series airplanes, and A300–600ST airplanes. Model A300–600ST 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. This proposed AD was prompted by reports of incorrect installation of the FSOV actuator, which was found to rotate around its pivot axis. The FAA is proposing this AD to address incorrect installation of the FSOV actuator. This condition, if not addressed, could lead to FSOV failure, and consequent risk of a temporary uncontrolled engine fire, possibly resulting in damage to, and reduced control of, the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 rotation around its pivot axis, and replacement. EASA AD 2021–0106 also describes procedures for reporting inspection results to Airbus. 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 2021–0106 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 EASA AD 2021–0106 describes procedures for a one-time detailed inspection of the FSOV actuator for 55543 process, the FAA developed a process to use certain civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 2021–0106 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021–0106 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 EASA AD 2021– 0106 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 EASA AD 2021–0106. Service information specified in EASA AD 2021–0106 that is required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0668 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 128 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 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $10,880 * 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 $10,880, or $85 per product. 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 this on-condition action: jspears on DSK121TN23PROD with PROPOSALS1 ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 3 work-hours × $85 per hour = $255 ...................................................................................................................... $28,000 $28,255 Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to VerDate Sep<11>2014 16:54 Oct 05, 2021 Jkt 256001 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 PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information E:\FR\FM\06OCP1.SGM 06OCP1 55544 Federal Register / Vol. 86, No. 191 / Wednesday, October 6, 2021 / Proposed Rules 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 jspears on DSK121TN23PROD with PROPOSALS1 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. 16:54 Oct 05, 2021 Jkt 256001 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 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. VerDate Sep<11>2014 List of Subjects in 14 CFR Part 39 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Airbus SAS: Docket No. FAA–2021–0668; Project Identifier MCAI–2021–00457–T.

(d) Subject Air Transport Association (ATA) of America Code 29, Hydraulic power. (e) Reason This AD was prompted by reports of incorrect installation of the fire shut-off valves (FSOV) actuator, which was found to rotate around its pivot axis. The FAA is issuing this AD to address incorrect installation of the FSOV actuator. This condition, if not addressed, could lead to FSOV failure, and consequent risk of a temporary uncontrolled engine fire, possibly resulting in damage to, and reduced control of, the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 (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 2021–0106, dated April 15, 2021 (EASA AD 2021–0106). (h) Exceptions to EASA AD 2021–0106 (1) Where EASA AD 2021–0106 refers to its effective date, this AD requires using the effective date of this AD. (2) The ‘‘Remarks’’ section of EASA AD 2021–0106 does not apply to this AD. (3) Paragraph (4) of EASA AD 2021–0106 specifies to report inspection results to Airbus within a certain compliance time. For this AD, report inspection results at the applicable time specified in paragraph (h)(3)(i) or (ii) of this AD. (i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection. (ii) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD. (4) Where the service information referenced in EASA AD 2021–0106 specifies to send the FSOV actuator for repair if it moves (rotates around its pivot axis) during the inspection, this AD requires replacing any FSOV actuator that moves (rotates around its pivot axis) during the inspection with a serviceable actuator, as specified in EASA AD 2021–0106. (i) 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.

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 all Airbus SAS Model A300 series airplanes; Airbus SAS Model A300 
B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R 
Variant F airplanes (collectively called Model A300-600 series 
airplanes); and Airbus SAS Model A310 series airplanes. This proposed 
AD was prompted by reports of incorrect installation of the fire shut-
off valves (FSOV) actuator, which was found to rotate around its pivot 
axis. This proposed AD would require a one-time detailed inspection of 
the FSOV actuator for rotation around its pivot axis, and replacement 
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 November 
22, 2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0106, dated April 15, 2021 
(EASA AD 2021-0106) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus SAS Model A300, A310, A300-600 series airplanes, and 
A300-600ST airplanes. Model A300-600ST 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.
    This proposed AD was prompted by reports of incorrect installation 
of the FSOV actuator, which was found to rotate around its pivot axis. 
The FAA is proposing this AD to address incorrect installation of the 
FSOV actuator. This condition, if not addressed, could lead to FSOV 
failure, and consequent risk of a temporary uncontrolled engine fire, 
possibly resulting in damage to, and reduced control of, the airplane. 
See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0106 describes procedures for a one-time detailed 
inspection of the FSOV actuator for rotation around its pivot axis, and 
replacement. EASA AD 2021-0106 also describes procedures for reporting 
inspection results to Airbus.
    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 2021-0106 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 developed a process to use certain civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA AD 2021-0106 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with EASA 
AD 2021-0106 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 EASA AD 2021-0106 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 EASA AD 2021-
0106. Service information specified in EASA AD 2021-0106 that is 
required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0668 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 128 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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................              $0              $85          $10,880
----------------------------------------------------------------------------------------------------------------
* 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 $10,880, or $85 per product.
    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 this on-condition action:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
3 work-hours x $85 per hour = $255....         $28,000          $28,255
------------------------------------------------------------------------

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

[[Page 55544]]

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.

List of Subjects in 14 CFR Part 39

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

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

    This AD was prompted by reports of incorrect installation of the 
fire shut-off valves (FSOV) actuator, which was found to rotate 
around its pivot axis. The FAA is issuing this AD to address 
incorrect installation of the FSOV actuator. This condition, if not 
addressed, could lead to FSOV failure, and consequent risk of a 
temporary uncontrolled engine fire, possibly resulting in damage to, 
and reduced control of, the airplane.

(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, European Union Aviation Safety Agency (EASA) AD 
2021-0106, dated April 15, 2021 (EASA AD 2021-0106).

(h) Exceptions to EASA AD 2021-0106

    (1) Where EASA AD 2021-0106 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2021-0106 does not apply 
to this AD.
    (3) Paragraph (4) of EASA AD 2021-0106 specifies to report 
inspection results to Airbus within a certain compliance time. For 
this AD, report inspection results at the applicable time specified 
in paragraph (h)(3)(i) or (ii) of this AD.
    (i) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (ii) If the inspection was done before the effective date of 
this AD: Submit the report within 30 days after the effective date 
of this AD.
    (4) Where the service information referenced in EASA AD 2021-
0106 specifies to send the FSOV actuator for repair if it moves 
(rotates around its pivot axis) during the inspection, this AD 
requires replacing any FSOV actuator that moves (rotates around its 
pivot axis) during the inspection with a serviceable actuator, as 
specified in EASA AD 2021-0106.

(i) 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 (j)(2) 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 
paragraphs (i)(2) and (h)(4) of this AD, if any service information 
referenced in EASA AD 2021-0106 contains paragraphs that are labeled 
as RC, the instructions in RC paragraphs, including subparagraphs 
under an RC paragraph, must be done to comply

[[Page 55545]]

with this AD; any paragraphs, including subparagraphs under those 
paragraphs, that are not identified as RC are recommended. The 
instructions in paragraphs, including subparagraphs under those 
paragraphs, 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 
instructions identified as RC can be done and the airplane can be 
put back in an airworthy condition. Any substitutions or changes to 
instructions identified as RC require approval of an AMOC.
    (4) Paperwork Reduction Act Burden Statement: A federal agency 
may not conduct or sponsor, and a person is not required to respond 
to, nor shall a person be subject to a 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 OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately 1 
hour per response, including the time for reviewing instructions, 
searching existing data sources, gathering and maintaining the data 
needed, and completing and reviewing the collection of information. 
All responses to this collection of information are mandatory as 
required by this AD. Send comments regarding this burden estimate or 
any other aspect of this collection of information, including 
suggestions for reducing this burden to Information Collection
