SUPPLEMENTARY INFORMATION:

[[Page 15124]]

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 
August 17, 2016 (81 FR 54750) (``the NPRM''). The NPRM was prompted by 
a report indicating that the fire block in the closets and video 
control stations, and fire blocking tape in the floor panel opening in 
the forward and aft main passenger cabin, might be missing on some 
airplanes. The NPRM proposed to require installing a fire block in the 
closets and video control stations, as applicable, and installing fire 
blocking tape in the floor panel openings in the forward and aft main 
passenger cabin. We are issuing this AD to prevent propagation of a 
fire in the lower lobe cheek area outboard of a closet or video control 
station. Such propagation could result in an increased risk of smoke 
and/or fire propagation into the passenger cabin.

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.

Support for NPRM

    The Air Line Pilots Association, International indicated its 
support for the intent of the NPRM.

Request To Clarify the Unsafe Condition

    Boeing asked that we clarify certain language related to the unsafe 
condition throughout the NPRM. Boeing stated that the location of the 
unsafe condition, referred to in the NPRM as ``video control station 
and closets,'' should be changed to ``closets and video control 
stations.'' Boeing stated that closets and video control stations are 
two separate monument designs, and the current wording implies that the 
requirement applies only to monuments with video controls.
    We agree with the commenter's request for the reason provided. We 
have clarified this language in all applicable sections of this AD.

Request To Include Later Revision of Service Information

    United Airlines (UA) asked that we include Issue 002 of Boeing 
Alert Service Bulletin B787-81205-SB530018-00, for accomplishing 
certain actions in the proposed AD. UA stated that it was informed by 
Boeing that Issue 002 is in work. UA noted that adding this later 
revision will minimize potential requests for alternative methods of 
compliance (AMOCs).
    We do not agree with the commenter's request. We do not consider 
that delaying this final rule until after the release of the 
manufacturer's planned service information (Issue 002 of Boeing Alert 
Service Bulletin B787-81205-SB530018-00) is warranted. We have 
identified an unsafe condition and the actions specified in Boeing 
Alert Service Bulletin B787-81205-SB530018-00, Issue 001, dated June 7, 
2013, address the unsafe condition for airplanes identified in 
paragraph (g)(3) of this AD. However, under the provisions of paragraph 
(h) of this AD, operators may request approval to use later revisions 
of the service information as an AMOC with this AD. We have not changed 
this AD in this regard.

Request To Issue Two ADs Instead of One

    UA asked that we split the NPRM into two ADs; one AD for Boeing 
Alert Service Bulletin B787-81205-SB250028-00, Issue 001, dated August 
1, 2013; and Boeing Alert Service Bulletin B787-81205-SB250070-00, 
Issue 001, dated March 10, 2015; and one AD for Boeing Alert Service 
Bulletin B787-81205-SB530018-00, Issue 001, dated June 7, 2013. UA 
stated that although all of this service information addresses fire 
blocking, different areas with different procedures are specified in 
each service bulletin.
    We do not agree with the commenter's request. We do not consider 
that delaying this final rule, so that the required actions can be 
split into two ADs based on the location of the corrective actions, is 
warranted. In order to address the identified unsafe condition in a 
timely manner, we find that we must issue this AD by mandating the 
specified actions described in the referenced service information. We 
have not changed this AD in this regard.

Request To Clarify Certain Action in the Costs of Compliance Section

    Boeing asked that we change the phrase ``video control closet'' to 
``closet'' in the Costs of Compliance section, for clarification. 
Boeing stated that the referenced service information does not have a 
monument listing for a ``video control closet'' but lists this monument 
as a ``closet.''
    We agree with the commenter's request for the reason provided. We 
have changed this language in the Costs of Compliance section 
accordingly.

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 the following service information:
    Boeing Alert Service Bulletin B787-81205-SB250028-00, Issue 001, 
dated August 1, 2013. The service information describes procedures for 
installing a fire block in the closets and video control stations.
    Boeing Alert Service Bulletin B787-81205-SB250070-00, Issue 001, 
dated March 10, 2015. The service information describes procedures for 
installing a fire block in the video control station.
    Boeing Alert Service Bulletin B787-81205-SB530018-00, Issue 001, 
dated June 7, 2013. The service information describes procedures for 
installing fire blocking tape in the floor panel openings in the 
forward and aft main passenger cabin.
    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 6 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

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

    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.

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.
