The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2023–0661; Project Identifier MCAI–2022–00737–Q] RIN 2120–AA64 Airworthiness Directives; Ipeco Pilot and Co-Pilot Seats Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2019–21–06, which applies to certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 2019–21–06 requires modification and reidentification of the affected seats, initial and repetitive inspections of the affected track lock springs and, depending on the findings, replacement of the track lock springs with a part eligible for installation. Since the FAA issued AD 2019–21–06, the FAA determined the need for a mandatory terminating action to the track lock spring inspections. This proposed AD was prompted by reports of track lock spring failures occurring on affected seats. This proposed AD would retain the requirements of AD 2019–21–06. This proposed AD would also add a mandatory terminating action for the initial and repetitive inspections of the affected track lock springs. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this NPRM by May 25, 2023. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to regulations.gov.

Submissions containing CBI should be sent to Kevin Kung, Aviation Safety Engineer, Boston ACO Branch, FAA, 1200 District Avenue, Burlington, MA 01803. 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 FAA issued AD 2019–21–06, Amendment 39–19772 (84 FR 60325, November 8, 2019) (AD 2019–21–06), for certain Ipeco pilot and co-pilot seats. AD 2019–21–06 was prompted by an MCAI originated by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued EASA AD 2018–0262, dated December 6, 2018 (EASA AD 2018– 0262), to correct an unsafe condition identified as reports of track lock spring failures occurring on affected seats, including those seats already modified by EASA AD 2016–0256, dated December 16, 2016 (EASA AD 2016– 0256). AD 2019–21–06 requires modification and re-identification of the affected seats, initial and repetitive inspections of the affected track lock springs and, depending on the findings, replacement of the track lock springs with a part E:\FR\FM\10APP1.SGM 10APP1 21115 Federal Register / Vol. 88, No. 68 / Monday, April 10, 2023 / Proposed Rules eligible for installation. AD 2019–21–06 also adds additional seat part numbers to the applicability. The FAA issued AD 2019–21–06 to prevent unexpected movement of pilot and co-pilot seats on takeoff and landing. Actions Since AD 2019–21–06 Was Issued Since the FAA issued AD 2019–21– 06, the Civil Aviation Authority (CAA), which is the aviation authority for the United Kingdom (UK) (UK CAA), superseded EASA AD 2018–0262 and issued UK CAA AD G–2022–0011, dated June 9, 2022 (UK CAA AD G–2022– 0011) (also referred to after this as the MCAI). The MCAI states that occurrences of track lock spring failures continued to be reported, including seats already modified, as required by EASA AD 2016–0256. Consequently, the manufacturer published revised service information, which specifies instructions for inspection and replacement, if necessary, of affected track lock springs. The MCAI partially retains the requirements of EASA AD 2018–0262, which is superseded. The MCAI maintains the inspection of affected seats and springs and, depending on the results of the inspection, replacement of the affected springs from EASA AD 2018–0262. The MCAI also adds a mandatory terminating action, which requires that replacement of affected springs and lever, and the installation of a lever control placard, is accomplished. Track lock spring failures, if not addressed, could lead to further cases of unexpected movement of pilot and copilot seats on takeoff and landing, which could result in reduced control of the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–0661. Related Service Information Under 1 CFR Part 51 The FAA reviewed Ipeco Service Bulletin (SB) Number 063–25–15, Issue 2; SB Number 063–25–16, Issue 2; SB Number 063–25–17, Issue 2; and SB Number 063–25–18, Issue 2; all dated March 8, 2022. These SBs provide instructions for removal and replacement of the levers and springs of affected track lock springs and the installation of a lever control placard. This proposed AD would also require Ipeco SB Number 063–25–08, Revision 00; SB Number 063–25–09, Revision 00; and SB Number 063–25–10, Revision 00; all dated May 31, 2016, which the Director of the Federal Register approved for incorporation by reference as of December 12, 2017 (82 FR 51552, November 7, 2017). This proposed AD would also require Ipeco SB Number 063–25–14, Revision 00, dated August 14, 2018, which the Director of the Federal Register approved for incorporation by reference as of December 13, 2019 (84 FR 60325, November 8, 2019). This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES. FAA’s Determination These products have been approved by the aviation authority of another country and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information described above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of these same type designs. Proposed AD Requirements in This NPRM This proposed AD would retain all of the requirements of AD 2019–21–06. This proposed AD would also add a mandatory terminating action for the initial and repetitive inspections of the affected track lock springs. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 120 pilot and co-pilot seats installed on, but not limited to, ATR 42 and ATR 72 airplanes of U.S. registry. The FAA estimates that seats installed on 34 ATR 42 airplanes and seats installed on 21 ATR 72 airplanes will require modification and inspection. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Cost per product Parts cost Cost on U.S. operators Action Labor cost Inspect ATR 42 or ATR 72 flight crew seats .. Modify ATR 42 or ATR 72 flight crew seats ... Report results of ATR 42 or ATR 72 inspection. Modify ATR 42 or ATR 72 flight crew seats per mandatory terminating action. 0.25 work-hours × $85 per hour = $21.25 ..... 2 work-hours × $85 per hour = $170 ............. 1 work-hour × $85 per hour = $85 ................. $0 56 0 $21.25 226 85 $2,550 27,120 10,200 2.5 work-hours × $85 per hour = $212.50 ..... 56 268.50 32,220 The FAA estimates the following costs to do any necessary replacements that would be required based on the results of the inspection. The FAA has no way of determining the number of aircraft that might need these replacements: ddrumheller on DSK120RN23PROD with PROPOSALS1 ON-CONDITION COSTS Action Labor cost Remove seat and replace ATR 42 track lock spring ... Remove seat and replace ATR 72 track lock spring ... 1.5 work-hours × $85 per hour = $127.50 ................... 1.50 work-hours × $85 per hour = $127.50 ................. The FAA has included all known costs in its cost estimate. According to VerDate Sep<11>2014 16:51 Apr 07, 2023 Jkt 259001 the manufacturer, however, some of the costs of this proposed AD may be PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 Parts cost Cost per product $28 28 covered under warranty, thereby E:\FR\FM\10APP1.SGM 10APP1 $155.50 155.50 21116 Federal Register / Vol. 88, No. 68 / Monday, April 10, 2023 / Proposed Rules reducing the cost impact on affected operators. 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 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 currently 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. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177–1524. ddrumheller on DSK120RN23PROD with PROPOSALS1 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 16:51 Apr 07, 2023 Jkt 259001 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: 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 [Amended] 2. The FAA amends § 39.13 by: ■ a. Removing Airworthiness Directive 2019–21–06, Amendment 39–19772 (84 FR 60325, November 8, 2019); and ■ b. Adding the following new airworthiness directive: ■ Authority for This Rulemaking VerDate Sep<11>2014 responsibilities among the various levels of government. For the reasons discussed above, I certify that the 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.

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2019-21-06, which applies to certain Ipeco Holdings Limited (Ipeco) 
pilot and co-pilot seats. AD 2019-21-06 requires modification and re-
identification of the affected seats, initial and repetitive 
inspections of the affected track lock springs and, depending on the 
findings, replacement of the track lock springs with a part eligible 
for installation. Since the FAA issued AD 2019-21-06, the FAA 
determined the need for a mandatory terminating action to the track 
lock spring inspections. This proposed AD was prompted by reports of 
track lock spring failures occurring on affected seats. This proposed 
AD would retain the requirements of AD 2019-21-06. This proposed AD 
would also add a mandatory terminating action for the initial and 
repetitive inspections of the affected track lock springs. The FAA is 
proposing this AD to address the unsafe condition on these products.

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 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 Kevin 
Kung, Aviation Safety Engineer, Boston ACO Branch, FAA, 1200 District 
Avenue, Burlington, MA 01803. 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 FAA issued AD 2019-21-06, Amendment 39-19772 (84 FR 60325, 
November 8, 2019) (AD 2019-21-06), for certain Ipeco pilot and co-pilot 
seats. AD 2019-21-06 was prompted by an MCAI originated by the European 
Aviation Safety Agency (EASA), which is the Technical Agent for the 
Member States of the European Union. EASA issued EASA AD 2018-0262, 
dated December 6, 2018 (EASA AD 2018-0262), to correct an unsafe 
condition identified as reports of track lock spring failures occurring 
on affected seats, including those seats already modified by EASA AD 
2016-0256, dated December 16, 2016 (EASA AD 2016-0256).
    AD 2019-21-06 requires modification and re-identification of the 
affected seats, initial and repetitive inspections of the affected 
track lock springs and, depending on the findings, replacement of the 
track lock springs with a part

[[Page 21115]]

eligible for installation. AD 2019-21-06 also adds additional seat part 
numbers to the applicability. The FAA issued AD 2019-21-06 to prevent 
unexpected movement of pilot and co-pilot seats on takeoff and landing.

Actions Since AD 2019-21-06 Was Issued

    Since the FAA issued AD 2019-21-06, the Civil Aviation Authority 
(CAA), which is the aviation authority for the United Kingdom (UK) (UK 
CAA), superseded EASA AD 2018-0262 and issued UK CAA AD G-2022-0011, 
dated June 9, 2022 (UK CAA AD G-2022-0011) (also referred to after this 
as the MCAI). The MCAI states that occurrences of track lock spring 
failures continued to be reported, including seats already modified, as 
required by EASA AD 2016-0256. Consequently, the manufacturer published 
revised service information, which specifies instructions for 
inspection and replacement, if necessary, of affected track lock 
springs. The MCAI partially retains the requirements of EASA AD 2018-
0262, which is superseded. The MCAI maintains the inspection of 
affected seats and springs and, depending on the results of the 
inspection, replacement of the affected springs from EASA AD 2018-0262. 
The MCAI also adds a mandatory terminating action, which requires that 
replacement of affected springs and lever, and the installation of a 
lever control placard, is accomplished. Track lock spring failures, if 
not addressed, could lead to further cases of unexpected movement of 
pilot and co-pilot seats on takeoff and landing, which could result in 
reduced control of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0661.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Ipeco Service Bulletin (SB) Number 063-25-15, 
Issue 2; SB Number 063-25-16, Issue 2; SB Number 063-25-17, Issue 2; 
and SB Number 063-25-18, Issue 2; all dated March 8, 2022. These SBs 
provide instructions for removal and replacement of the levers and 
springs of affected track lock springs and the installation of a lever 
control placard.
    This proposed AD would also require Ipeco SB Number 063-25-08, 
Revision 00; SB Number 063-25-09, Revision 00; and SB Number 063-25-10, 
Revision 00; all dated May 31, 2016, which the Director of the Federal 
Register approved for incorporation by reference as of December 12, 
2017 (82 FR 51552, November 7, 2017).
    This proposed AD would also require Ipeco SB Number 063-25-14, 
Revision 00, dated August 14, 2018, which the Director of the Federal 
Register approved for incorporation by reference as of December 13, 
2019 (84 FR 60325, November 8, 2019).
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in ADDRESSES.

FAA's Determination

    These products have been approved by the aviation authority of 
another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, it has notified the FAA of the unsafe condition described in 
the MCAI and service information described above. The FAA is issuing 
this NPRM after determining that the unsafe condition described 
previously is likely to exist or develop on other products of these 
same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all of the requirements of AD 2019-
21-06. This proposed AD would also add a mandatory terminating action 
for the initial and repetitive inspections of the affected track lock 
springs.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 120 pilot and co-pilot seats installed on, but not limited to, 
ATR 42 and ATR 72 airplanes of U.S. registry. The FAA estimates that 
seats installed on 34 ATR 42 airplanes and seats installed on 21 ATR 72 
airplanes will require modification and inspection.
    The FAA estimates the following costs to comply with this proposed 
AD:

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
inspection. The FAA has no way of determining the number of aircraft 
that might need these replacements:

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 
proposed AD may be covered under warranty, thereby

reducing the cost impact on affected operators.

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 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 currently 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. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, 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 that the 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.
