[Docket No. FAA-2019-0260; Product Identifier 2017-NE-13-AD; Amendment 
39-19772; AD 2019-21-06]
RIN 2120-AA64


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) 2017-22-02 
for certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 
2017-22-02 required modification and re-identification of the affected 
seats. This AD continues to require modification and re-identification 
of the affected seats. This AD also requires initial and repetitive 
inspections of the affected tracklock springs and, depending on the 
findings, replacement of the tracklock springs with a part eligible for 
installation. This AD was prompted by reports that the tracklock spring 
modification required by AD 2017-22-02 does not adequately address the 
issue of unexpected seat movement during takeoff and landing and the 
need to add additional seat part numbers (P/Ns) to the applicability. 
The FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective December 13, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 13, 
2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2017-22-02, Amendment 39-19082 (82 FR 
51552, November 7, 2017), (``AD 2017-22-02''). AD 2017-22-02 applied to 
certain Ipeco pilot and co-pilot seats. The NPRM published in the 
Federal Register on July 19, 2019 (84 FR 34816). The NPRM was prompted 
by reports of tracklock spring failures occurring on affected seats, 
including those seats already modified by AD 2017-22-02. The NPRM 
proposed to retain all the requirements of AD 2017-22-02 and add 
additional seat P/Ns to the applicability. The NPRM also proposed to 
require initial and repetitive inspections of the affected tracklock 
springs and, depending on the findings, replacement of the tracklock 
springs with a part eligible for installation. The FAA is issuing this 
AD to address the unsafe condition on these products.
    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community, has 
issued EASA AD 2018-0262, dated December 6, 2018, (referred to after 
this as ``the MCAI''), to address the unsafe condition on these 
products. The MCAI states:

    Occurrences have been reported of pilot/co-pilot unexpected 
rearward movement during take-off and landing. Investigations 
determined that horizontal guide block wear, presence of burrs on 
horizontal centre track and horizontal track lock system weakness 
(spring tension too low) were causes which contributed to the seat 
not being correctly locked.
    This condition, if not corrected, could lead to further cases of 
unwanted flight crew seat movement, possibly resulting in reduced 
control of the aeroplane.
    To address this potential unsafe condition, IPECO improved the 
quality control on the final assembly line and issued the applicable 
modification SB, providing modification instructions, and EASA 
issued AD 2016-0256, requiring modification of pre-mod seats and 
subsequent re-identification with a new P/N.
    Since that AD was issued, occurrences of track lock spring 
failures have been reported on affected seats (including seats 
already modified as required by EASA AD 2016-0256). Consequently, 
IPECO published the inspection SB, providing applicable instructions 
to inspect and replace, if necessary, any affected spring of each 
affected seat.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0256, which is superseded, and requires 
repetitive inspection of seats and, depending on findings, 
replacement of affected springs and reporting to IPECO.

    You may obtain further information by examining the MCAI in the AD 
docket on the internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2019-0260.

Comments

    The FAA gave the public the opportunity to participate in 
developing this AD. The FAA received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this AD 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 Service Information Under 1 CFR Part 51

    The FAA reviewed Ipeco Service Bulletin (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. The SBs provide instructions, 
differentiated by the part numbers of the affected pilot and co-pilot 
seats, for the modification and re-identification of these seats. The 
FAA also reviewed Ipeco SB Number 063-25-14, Revision 00, dated August 
14, 2018. This SB provides instructions for inspection and replacement, 
if necessary, of affected

tracklock springs. 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 the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 110 pilot and co-pilot seats 
installed on, but not limited to, ATR-GIE Avions de Transport Regional 
(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 revised the 
estimated number of affected seats in this cost estimate to include two 
affected seats per airplane.
    The FAA estimates the following costs to comply with this AD:

    According to the manufacturer, some 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 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

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
    (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.
