39-19082; AD 2017-22-02]

Airworthiness Directives; IPECO Pilot and Co-Pilot Seats

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Ipeco Holdings Ltd. (Ipeco) pilot and co-pilot seats. This AD requires 
modification and reidentification of the affected seats. This AD was 
prompted by reports of unexpected movement of pilot and co-pilot seats 
on takeoff and landing. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD becomes effective December 12, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 12, 
2017.

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 the specified products. The 
NPRM was published in the Federal Register on June 16, 2017 (82 FR 
27629). The NPRM proposed to correct an unsafe condition for the 
specified 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 various 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.

    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-2017-0490.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Request To Shorten Compliance Time

    The Air Line Pilots Association (ALPA) requested that the FAA work 
with EASA to reevaluate the compliance time for this AD. ALPA indicated 
that the requirements of this AD could be accomplished in a shorter 
timeframe that would enhance safety.
    ALPA did not provide data or a detailed explanation with respect to 
its request for a shorter time frame. Consequently, upon further review 
of the risk analysis with EASA, we determined the proposed time frame 
for accomplishment of this AD is appropriate.

Miscellaneous Comments

    We received miscellaneous comments not relevant to this AD. No 
further response is required.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed.

Related Service Information Under 1 CFR Part 51

    Ipeco has issued 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. These SBs provide instructions, 
differentiated by the part numbers of the affected pilot and co-pilot 
seats, for the modification and reidentification of these seats. 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 pilot and co-
pilot seats installed on 55 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

    We determined that 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.
