SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking NPRM to amend 14 CFR part 
39 by adding an AD that would apply to certain Zodiac Seats France 536 
Series Cabin Attendant Seats. The NPRM published in the Federal 
Register on December 22, 2017 (82 FR 60690). The NPRM was prompted by 
cracks found in a highly concentrated stress area of the seat pan 
hinges. The NPRM proposed to require repetitive inspections of the 
affected cabin attendant seats and, depending on findings, replacement 
of the seat pan. We are issuing this AD to address the unsafe condition 
on these products.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2017-0001, dated January 6, 2017 (referred to after this as ``the 
MCAI'') to correct an unsafe condition for the specified products. The 
MCAI states:

    Cases of cracks were found on Zodiac Seats France cabin 
attendant seats 536 series installed on some ATR 42 and ATR 72 
aeroplanes. The detected damage was located in the area of the seat 
pan hinges. Investigations identified that fatigue had caused these 
cracks in a highly concentrated stress area.
    This condition, if not detected and corrected, could lead to 
failure of the seat, possibly resulting in injury to the seat 
occupant.
    To address this potential unsafe condition, Zodiac Seats France 
issued Service Bulletin (SB) 536-25-003 to provide inspection and 
replacement instructions. Consequently, EASA issued AD 2016-0164, 
requiring repetitive visual inspections of the affected cabin 
attendant seats and, depending on findings, replacement of the seat 
pan.
    Since that AD was issued, Zodiac Seats France developed a 
reinforced seat pan, and revised SB 536-25-003 accordingly. After 
installation of a reinforced seat pan, the seat P/N amendment status 
is updated.
    For the reason described above, this AD retains the requirements 
of EASA AD 2016-0164, which is superseded, prohibits installation of 
unreinforced seat pans on seats already modified, and introduces the 
reinforced seat pan installation as optional terminating action for 
the repetitive inspections.

    You may obtain further information by examining the MCAI in the AD 
docket on the internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2017-0632.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule as proposed except 
for minor editorial changes. We have 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

    We reviewed Zodiac Seats France Service Bulletin (SB) No. 536-25-
003, Rev. 3, dated June 2, 2017. The SB describes procedures for 
inspection, modification, or replacement of the seat pan of certain 
model seats known to be installed on ATR 42 and ATR 72 airplanes. 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

    We estimate that this AD affects 55 seat assemblies installed on, 
but not limited to, ATR 42 and ATR 72 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Seat inspection, modification, or       1.2 work-hours x $85 per          $1,500          $1,602         $88,110
 replacement.                            hour = $102.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have 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.
    We are 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 this AD:

[[Page 59290]]

    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
