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 and 787-9 airplanes. This AD was
prompted by a determination that certain areas in the tire/wheel threat
zones could be susceptible to damage, which could result in loss of
braking on one main landing gear (MLG) truck, loss of nose wheel
steering, and loss of directional control on the ground when below
rudder effectiveness speed. This AD requires installing hydraulic
tubing, a pressure-operated check valve, and new flight control
software. We are issuing this AD to address the unsafe condition on
these products.
DATES: This AD is effective June 6, 2019.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of June 6, 2019.

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 and 787-9 airplanes. The NPRM published in the Federal
Register on August 31, 2018 (83 FR 44508). The NPRM was prompted by a
determination that certain areas in the tire/wheel threat zones could
be susceptible to damage, which could result in loss of braking on one
MLG truck, loss of nose wheel steering, and loss of directional control
on the ground when below rudder effectiveness speed.
[[Page 18708]]
The NPRM proposed to require installing hydraulic tubing, a pressure-
operated check valve, and new flight control software.
We are issuing this AD to address damage from a MLG thrown tire
tread or tire burst event, which could result in loss of directional
control on the ground and consequent runway excursion.
Comments
We gave the public the opportunity to participate in developing
this final rule. The following presents the comments received on the
NPRM and the FAA's response to each comment.
Support for the NPRM
The Air Line Pilots Association, International (ALPA) stated it
agrees with the intent of the NPRM. Boeing stated it concurs with the
contents of the NPRM.
Request To Include Service Information Notice in Paragraph (g)(1) of
the Proposed AD
American Airlines asked that Boeing Information Notice B787-A-29-
00-0032-01A-931E-D, Issue 001, dated June 12, 2018, be added to
paragraph (g)(1) of the proposed AD as an additional source of service
information for accomplishing the required actions. American Airlines
stated that the information notice contains corrections to Boeing Alert
Service Bulletin B787-81205-SB290032-00, Issue 001, dated November 17,
2017, including to the aircraft configuration and accomplishment
instructions. American Airlines added that, as written, the proposed AD
would require an alternative method of compliance for operators to
accomplish the modification following the instructions in this service
information.
We agree to address the corrections in Boeing Information Notice
B787-A-29-00-0032-01A-931E-D, Issue 001, dated June 12, 2018, in this
AD. Boeing has issued Boeing Alert Service Bulletin B787-81205-
SB290032-00, Issue 002, dated February 1, 2019, which includes the
corrections and clarifications specified in Boeing Information Notice
B787-A-29-00-0032-01A-931E-D, Issue 001, dated June 12, 2018. We have
determined these corrections and clarifications to the service
information do not change the substantive requirements of this AD but
rather make the requirements more accurate and understandable. We have
further determined that Issue 002 of Boeing Alert Service Bulletin
B787-81205-SB290032-00 does not require additional work for airplanes
on which the actions specified in Issue 001 have been done.
Therefore, we revised the ``Related Service Information under 1 CFR
part 51'' paragraph of this final rule, and paragraphs (c)(1) and
(g)(1) of this AD, to refer to Boeing Alert Service Bulletin B787-
81205-SB290032-00 Issue 002, dated February 1, 2019. We also provide
credit in this AD for using Boeing Alert Service Bulletin B787-81205-
SB290032-00, Issue 001, dated November 17, 2017; and for using Boeing
Alert Service Bulletin B787-81205-SB290032-00, Issue 001, dated
November 17, 2017, in conjunction with Boeing Information Notice B787-
A-29-00-0032-01A-931E-D, Issue 001, dated June 12, 2018.
Request To Address Service Information Errors
Japan Airlines requested that we refer to a revised service
bulletin to address two errors found in Boeing Alert Service Bulletin
B787-81205-SB290033-00, Issue 001, dated November 17, 2017. Japan
Airlines stated that there are incorrect part numbers in multiple
locations in Figure 10 and Figure 11. Japan Airlines stated it
contacted Boeing to correct the errors, and Boeing stated that a
revision was in work.
We agree we should address the errors identified by the commenter
in this AD. We have confirmed the errors with Boeing; however, Boeing
has not yet issued revised service information. We have included the
corrections to the service information, including the part number
corrections identified by the commenter, as exceptions in this AD.
Request To Include Credit for Service Information Notice for Paragraph
(g)(2) of the Proposed AD
United Airlines asked that Boeing Information Notice B787-A-27-00-
0039-01A-931E-D, Issue 001, dated September 7, 2017, be approved as an
additional source of service information for accomplishing the required
actions (in paragraph (g)(2) of the proposed AD). United Airlines
stated that the information notice contains corrections to Boeing Alert
Service Bulletin B787-81205-SB270039-00, Issue 001, dated July 31,
2017, but noted the required software part numbers did not change.
We agree with the commenter since the information notice provides
the correct software location identification for a couple of steps and
refers to an alternative method of compliance to a different AD. We
have provided credit in this AD for using Boeing Alert Service Bulletin
B787-81205-SB270039-00, Issue 001, dated July 31, 2017, in conjunction
with Boeing Information Notice B787-A-27-00-0039-01A-931E-D, Issue 001,
dated September 7, 2017.
Change to Paragraph (g)(2) of This AD
Paragraph (g)(2) of the proposed AD specifies to install new
software as specified in Boeing Alert Service Bulletin B787-81205-
SB270039-00, Issue 002, dated March 8, 2018, for certain Model 787-9
airplanes. In addition to the software identified in Boeing Alert
Service Bulletin B787-81205-SB270039-00, Issue 002, dated March 8,
2018, we have determined that later-approved software versions are
acceptable for compliance, provided those later-approved versions meet
certain conditions. We have revised paragraph (g)(2) of this AD to
allow later-approved software versions.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this final rule 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 addressing 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 final
rule.

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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.
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.
