SUPPLEMENTARY INFORMATION:
Discussion
We have received reports indicating that an FCM will reset if
continuously powered on for 22 days. This condition, if not corrected,
could result in simultaneous resets of all three FCMs, which could
result in flight control surfaces not moving in response to flight crew
inputs for a short time and consequent temporary loss of
controllability. We are issuing this AD to correct the unsafe condition
on these products.
Related Service Information Under 1 CFR Part 51
We reviewed Boeing Alert Service Bulletin B787-81205-SB270040-00,
Issue 001, dated November 25, 2016. The service information describes
procedures for cycling the airplane electrical power and cycling power
to the three FCMs. 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-
9436.
Interim Action
We consider this AD interim action. Boeing and its suppliers are
developing a terminating solution to address the identified unsafe
condition. Once this terminating solution 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
simultaneous resets of all three FCMs could result in flight control
surfaces not moving in response to flight crew inputs for a short time
and consequent temporary loss of controllability. 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
[[Page 86913]]
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-2016-9436 and
Directorate Identifier 2016-NM-197-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.
Costs of Compliance
We estimate that this AD affects 99 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Cycling of either the airplane 1 work-hour x $85 per hour $85 per cycle......... $8,415 per cycle.

FCMs.
----------------------------------------------------------------------------------------------------------------
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.
