We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report of uncommanded movement by a captain's seat during a landing rollout due to a failure in the seat horizontal actuator. This AD requires repetitive tests of the captain and first officer seat assemblies for proper operation, and corrective action if necessary. This AD also requires installation of new captain and first officer seat assemblies, which terminates the repetitive tests. We are issuing this AD to prevent a seat actuator clutch failure, which could result in a loss of seat locking and uncommanded motion of the captain's or first officer's seat; uncommanded seat movement could result in reduced controllability of the airplane.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 787-8 airplanes. This AD was prompted by a 
report of uncommanded movement by a captain's seat during a landing 
rollout due to a failure in the seat horizontal actuator. This AD 
requires repetitive tests of the captain and first officer seat 
assemblies for proper operation, and corrective action if necessary. 
This AD also requires installation of new captain and first officer 
seat assemblies, which terminates the repetitive tests. We are issuing 
this AD to prevent a seat actuator clutch failure, which could result 
in a loss of seat locking and uncommanded motion of the captain's or 
first officer's seat; uncommanded seat movement could result in reduced 
controllability of the airplane.

DATES: This AD is effective October 31, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 31, 
2016.

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 The Boeing Company 
Model 787-8 airplanes. The NPRM published in the Federal Register on 
March 7, 2016 (81 FR 11687) (``the

[[Page 65858]]

NPRM''). The NPRM was prompted by a report of uncommanded movement by a 
captain's seat during a landing rollout due to a failure in the seat 
horizontal actuator. The NPRM proposed to require repetitive tests of 
the captain and first officer seat assemblies for proper operation, and 
corrective action if necessary. The NPRM also proposed to require 
installation of new captain and first officer seat assemblies, which 
would terminate the repetitive tests. We are issuing this AD to prevent 
a seat actuator clutch failure, which could result in a loss of seat 
locking and uncommanded motion of the captain's or first officer's 
seat; uncommanded seat movement could result in reduced controllability 
of the airplane.

Comments

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

Request To Remove Service Bulletin Issue Number and Date

    Boeing requested that we revise the NPRM to not specify the Service 
Bulletin issue number and date, or alternatively to include ``or 
subsequent'' when referencing Boeing Alert Service Bulletin B787-81205-
SB250054-00, Issue 001, dated December 19, 2014.
    Boeing commented that the seat supplier is currently working on a 
related nuisance issue of intermittent electrical operation of the 
seat-powered adjustment system. Boeing stated that the resolution to 
this issue may result in changes to the part numbers of the actuators 
and seat assemblies, and revision to the service bulletin issue number 
and date.
    We do not agree with the commenter's request to remove the issue 
number and date of the service information. We cannot allow use of 
``later-approved revisions'' in an AD when referring to the service 
document. Doing so violates Office of the Federal Register (OFR) 
regulations for approval of materials ``incorporated by reference,'' as 
specified in 1 CFR 51.1(f). If for any reason the issue and date of the 
service bulletin should change, the FAA may consider issuing an 
alternative method of compliance (AMOC) to allow use of a later 
revision. We have not changed this AD in this regard.

Request To Remove the Replacement Seat Part Numbers

    Boeing requested that we remove the replacement seat part numbers 
to be installed as terminating action from this AD, and instead specify 
that seats be replaced with part numbers ``as specified in Boeing Alert 
Service Bulletin B787-81205-SB250054-00.''
    Boeing commented that the seat supplier is currently working on a 
related nuisance issue of intermittent electrical operation of the 
seat-powered adjustment system. The resolution to this issue may result 
in change to the part numbers of the actuators and seat assemblies.
    We partially agree with the commenter's request. We have changed 
paragraph (h) of this AD to remove the part numbers of the actuators 
and seat assemblies from this AD and to include the part numbers 
specified in Boeing Alert Service Bulletin B787-81205-SB250054-00. 
However, we have included the revision level and date of the service 
information for the reasons noted in the previous comment response. The 
FAA may consider issuing an AMOC to allow use of a later revision of 
the service information.

Request To Allow Credit for Prior Accomplishment of Service Bulletins

    United Airlines requested that the AD allow credit for prior 
accomplishment of Boeing and Ipeco service information.
    We already provide credit in paragraph (f) of this AD for prior 
accomplishment of Boeing Alert Service Bulletin B787-81205-SB250054-00, 
Issue 001, dated December 19, 2014, if accomplished before the 
effective date of this AD. In addition, credit is not necessary for 
using the Ipeco service information referenced in Boeing Alert Service 
Bulletin B787-81205-SB250054-00, Issue 001, dated December 19, 2014, 
because this AD does not specifically require using Ipeco service 
information. No change to this AD is necessary.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB250054-00, 
Issue 001, dated December 19, 2014. This service information provides 
procedures for installation of new captain and first officer seat 
assemblies, a test of the captain and first officer seat assemblies, 
and corrective action if necessary. 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 18 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.

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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.
