Federal Register Volume 83, Issue 196 (October 10, 2018)

We are adopting a new airworthiness directive (AD) for certain GEVEN S.p.A. (Geven) Type D1-02 and D1-03 seat assemblies. This AD was prompted by a report that seat belt attachment bolts were found detached or partially detached from the seat. This AD requires inspection, torque verification, and modification of certain model seats. We are issuing this AD to address the unsafe condition on these products.

seats. We are issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective November 14, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 14, 
2018.

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 Geven, Type D1-02 
and D1-03 seat assemblies. The NPRM published in the Federal Register 
on July 14, 2017 (82 FR 32494). The NPRM was prompted by a report that 
seat belt attachment bolts were found detached or partially detached 
from the seat. The NPRM proposed to require inspection, torque 
verification, and modification of certain model seats. 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 2014-0187, dated August 20, 2014 (referred to after this as ``the 
MCAI''), to address the unsafe condition on these 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

[[Page 50817]]

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 EASA AD requires a one-time inspection of all safety 
belt attachment bolts and, depending on findings, accomplishment of 
the applicable corrective action(s). This EASA 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.

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.

Clarification to the Number of Affected Airplanes

    Since we issued the NPRM, we determined that we needed to identify 
the specific number of affected Avions de transport regional (ATR) 42 
and ATR 72 airplanes rather than list the overall number of airplanes 
that are affected. The estimated costs have not changed.

Clarification to Required Actions

    We also determined that the compliance in the NPRM was not clear as 
to which Geven seats required modification and which required bushing 
replacement. We have clarified the Required Actions in this AD. 
Additionally, all Geven Type D1-02 and D1-03 safety belt assemblies are 
torque checked, but, only Geven Type D1-03 seat belt attachment 
assemblies on the aisle side spreader must be modified.

Clarification of Service Information Reporting Requirements

    We also determined that Geven Service Bulletin (SB) No. D103-25-
004, Revision 4, dated March 15, 2016, specifies to submit certain 
information to the manufacturer. This AD does not include that 
requirement.

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 Geven 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.

Costs of Compliance

    We estimate that this AD affects an unknown number of seat 
assemblies installed on, but not limited to, 25 ATR 42 airplanes and 13 
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

                                      hour = $127.50.

                                      hour = $195.50.

                                      hour = $102.00.
----------------------------------------------------------------------------------------------------------------

    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:
    (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.
