Airworthiness Directives; GEVEN S.p.A., Seat Assemblies, Type D1-
02 and D1-03

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Geven S.p.A., Type D1-02 and D1-03 seat assemblies. This 
proposed AD was prompted by a report that seat belt attachment bolts 
were found detached or partially detached from the seat. This proposed 
AD would require inspection, torque verification, and modification of 
certain model seats. We are proposing this AD to correct the unsafe 
condition on these products.

DATES: We must receive comments on this NPRM by August 28, 2017.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2014-0187, dated August 20, 2014 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    An operator reported that seat belt attachment bolts were found 
detached or partially detached from the seat. A further check on 
several aeroplanes revealed that on a large number of seats of the 
same model, the seat belt attachment bolts were not properly torqued 
and secured as defined. This condition, if not detected and 
corrected, could lead to failure of the seats to perform their 
intended function, possibly resulting in injury to occupants in case 
of an emergency landing. To address this potential unsafe condition, 
Geven published SB No. D103-25-004 to provide inspection 
instructions to verify if the seat belt attachment bolts are 
properly torqued and secured, and correction of any deficiencies. In 
addition, for certain D1-03 seats, the SB provides instructions to 
modify the seat belt attachment assembly. For the reasons described 
above, this AD requires a one-time inspection of all safety belt 
attachment bolts and, depending on findings, accomplishment of the 
applicable corrective action(s). This AD also requires modification 
of the seat belt attachment assembly on certain D1-03 seats.

    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-2017-0504.

Related Service Information Under 1 CFR Part 51

    Geven S.p.A. has issued Service Bulletin (SB) No. D103-25-004, 
Revision 4, dated March 15, 2016. The SB describes procedures for 
inspection, torque verification, and modification 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 the aviation authority of Italy, 
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, torque verification 
and modification of certain model seats.

Costs of Compliance

    We estimate that this proposed AD affects an unknown number of seat 
assemblies installed on, but not limited to, 38 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 modification ATR 42...........  1.5 work-hours x $85 per               $302         $429.50      $10,737.50
                                      hour = $127.50.
Torque check ATR 42................  0.8 work-hours x $85 per                  0           68.00        1,700.00
                                      hour = $68.00.
Seat modification ATR 72...........  2.3 work-hours x $85 per                368          563.50        7,325.50
                                      hour = $195.50.
Seat remove and replace ATR 72.....  1.2 work-hours x $85 per                  0          102.00        1,326.00
                                      hour = $102.00.
----------------------------------------------------------------------------------------------------------------

    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.

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 to the extent 
that it justifies making a regulatory distinction, 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.
