SUPPLEMENTARY INFORMATION:
Discussion
We have received several reports of disengaged decompression panels
found on in-service airplanes. It appears these decompression panels
disengaged prior to delivery, during test flights. Tests done by the
airplane manufacturer revealed some decompression panels disengage at a
pressure differential below the design/intended value. This condition,
if not corrected, would provide a path for smoke and Halon to enter the
flight compartment and passenger cabin in the event of a cargo
compartment fire, which could result in the inability to contain and
extinguish a fire.
Related Service Information Under 1 CFR Part 51
We reviewed Boeing Alert Service Bulletin B787-81205-SB500009-00,
Issue 001, dated November 16, 2015. The service information describes
procedures for repetitive inspections of the bilge barriers located in
the forward and aft cargo compartments for disengaged decompression
panels, and reinstalling any disengaged panels. 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
We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
AD Requirements
This AD requires accomplishing the actions specified in the service
information described previously.
For information on the procedures and compliance times, see this
service information at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and
locating Docket No. FAA-2016-6149.
Interim Action
We consider this AD interim action. The airplane manufacturer is
currently developing a modification that will address the unsafe
condition identified in this AD. Once this modification is developed,
approved, and available, we might consider additional rulemaking.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because if
any decompression panel is disengaged from the bilge barriers located
in the forward and aft cargo compartments and a cargo compartment fire
were to occur, the fire could not be contained or extinguished.
Therefore, we find that notice and opportunity for prior public comment
are impracticable and that good cause exists for making this amendment
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include the docket number FAA-2016-6149 and
Directorate Identifier 2016-NM-047-AD at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this AD. We will
consider all comments received by the closing date and may amend this
AD because of those comments.
We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
[[Page 27302]]
Costs of Compliance
We estimate that this AD affects 42 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------

inspection cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary reinstallation
that would be required based on the results of the inspection. We have
no way of determining the number of aircraft that might need this
action:

----------------------------------------------------------------------------------------------------------------
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.
