RIN 2120-AA6

Airworthiness Directives; Zodiac Seats France, Cabin Attendant 
Seats

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Zodiac Seats France, 536 Series Cabin Attendant Seats. This 
proposed AD was prompted by cracks found in a highly concentrated 
stress area of the seat pan hinges. This proposed AD would require 
repetitive inspections and replacement of the seat pan. We are 
proposing this AD to correct the unsafe condition on these products.

DATES: We must receive comments on this NPRM by February 5, 2018.

Discussion

    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 hereinafter 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is superseded, prohibits installation of unreinforced seat pans on 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.

Related Service Information Under 1 CFR Part 51

    Zodiac Aerospace has issued Service Bulletin (SB) No. 536-25-003, 
Revision 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by EASA, and is approved for 
operation in the United States. Pursuant to our bilateral agreement 
with the European Community, EASA has notified us of the unsafe 
condition described in the MCAI and service information referenced 
above. We are proposing this AD because we evaluated all information 
provided by EASA and determined the unsafe condition exists and is 
likely to exist or develop on other products of the same type design. 
This proposed AD would require inspection, and modification of certain 
model seats.

Costs of Compliance

    We estimate that this proposed 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 proposed 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 proposed 
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

[[Page 60692]]

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

    We 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) 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.
