RIN 2120-AA64
Airworthiness Directives; The Boeing Company
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain The Boeing Company Model 787-8 and 787-9 airplanes. This
proposed AD was prompted by a report that some inboard and outboard
trailing edge flap rotary actuators may have been assembled with an
incorrect no-back brake rotor-stator stack sequence during
manufacturing. This proposed AD would require an inspection of the
inboard and outboard flap trailing edge rotary actuator for any
discrepant rotary actuator. For discrepant rotary actuators, this
proposed AD would require replacing the rotary actuator, or determining
the flight cycles on the rotary actuator and doing related
investigative and corrective actions if necessary. We are proposing
this AD to detect and replace rotary actuators having incorrect
assembly, which could cause accelerated unit wear that will eventually
reduce braking performance. This degradation could lead to loss of no-
back brake function and reduced controllability of the airplane.
DATES: We must receive comments on this proposed AD by August 26, 2016.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
We received a report that some inboard and outboard trailing edge
flap rotary actuators may have been assembled with an incorrect no-back
brake rotor-stator stack sequence during manufacturing. This condition,
if not corrected, could result in accelerated unit wear that will
eventually reduce braking performance. This degradation could lead to
loss of no-back brake function and reduced controllability of the
airplane.
Related Service Information Under 1 CFR Part 51
We reviewed Boeing Alert Service Bulletin B787-81205-SB270032-00,
Issue 001, dated November 3, 2015. The service information describes
procedures for an inspection of the inboard and outboard flap rotary
actuator for any discrepant rotary actuator, and procedures for
replacing the rotary actuator, or determining the flight cycles on the
rotary actuator and applicable related investigative and corrective
actions. 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 proposing 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.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in the service information described
[[Page 45071]]
previously. For information on the procedures and compliance times, see
this service information at http://www.regulations.gov by searching for
and locating Docket No. FAA-2016-7419.
``Related investigative actions'' are follow-on actions that (1)
are related to the primary action, and (2) are actions that further
investigate the nature of any condition found. Related investigative
actions in an AD could include, for example, inspections.
``Corrective actions'' are actions that correct or address any
condition found. Corrective actions in an AD could include, for
example, repairs.
Costs of Compliance
We estimate that this proposed AD affects 5 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection.......................... 1 work-hour x $85 per $0 $85 $425

----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary on-condition
actions that would be required based on the results of the proposed
inspection. We have no way of determining the number of aircraft that
might need this replacement:
On-Condition Costs

----------------------------------------------------------------------------------------------------------------
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
We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
(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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
