Airworthiness Directives; Ipeco Pilot and Co-Pilot Seats

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-21-
06, which applied to certain Ipeco Holdings Limited (Ipeco) pilot and 
co-pilot seats. AD 2019-21-06 required 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 AD is prompted by reports of track lock 
spring failures occurring on affected seats. This AD retains the 
requirements of AD 2019-21-06. This AD also adds a mandatory 
terminating action for the initial and repetitive inspections of the 
affected track lock springs. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective September 7, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 7, 
2023.

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-21-06, Amendment 39-19772 (84 FR 
60325, November 8, 2019) (AD 2019-21-06). AD 2019-21-06 applied to 
Ipeco pilot and co-pilot seats with a part number (P/N) listed in 
Paragraph 1.A., Planning Information, Tables 1 and 2, of Ipeco Service 
Bulletin (SB) Number 063-25-14, Revision 00, dated August 14, 2018, and 
Ipeco pilot seat P/N 3A063-0099-01-1 and Ipeco co-pilot seat P/N 3A063-
0100-01-1. 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 
required 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. The FAA issued AD 2019-21-06 to 
prevent unexpected movement of pilot and co-pilot seats on takeoff and 
landing.
    The NPRM published in the Federal Register on April 10, 2023 (88 FR 
21114). The NPRM was prompted by United Kingdom (UK) Civil Aviation 
Authority (CAA) AD G-2022-0011, dated June 9, 2022 (referred to after 
this as the MCAI), issued by UK CAA, which is the aviation authority 
for the UK. The MCAI states that occurrences of track lock spring 
failures continued to be reported, including seats already modified, as 
instructed 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; and EASA issued EASA AD 2018-0262 to supersede EASA AD 2016-
0256, which retained the modification and re-identification; and 
introduced new instructions to inspect for damage and incorrect 
installation of the track lock springs and, if necessary, replacement 
of both track lock springs of the affected seat. The MCAI supersedes 
EASA AD 2018-0262; removes the previous instructions for modification 
and re-identification; retains the inspection for damage and incorrect 
installation of the track lock springs; and introduces new instructions 
for replacement of the affected track lock springs and lever, and 
installation of a track lock lever control placard (modification and 
re-identification) as terminating action.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0661.
    In the NPRM, the FAA proposed to retain all of the requirements of 
AD 2019-21-06. The FAA also proposed to add a mandatory terminating 
action (modification and re-identification of each affected seat) for 
the initial and repetitive inspections of the affected track lock 
springs. The FAA is issuing this AD to prevent unexpected movement of 
pilot and co-pilot seats on takeoff and landing.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    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 referenced above. The FAA reviewed the relevant data and 
determined that air safety requires adopting this AD as proposed. 
Accordingly, the FAA is issuing this AD to address the unsafe condition 
on these products. Except for minor editorial changes this AD is 
adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Ipeco 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 track lock levers and springs and 
installation of a track lock lever control placard.
    This AD also requires 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 AD also requires 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.

Costs of Compliance

    The FAA estimates that this AD affects 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 require modification and 
inspection.

[[Page 51232]]

    The FAA estimates the following costs to comply with this AD:

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 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 has determined that 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.
