14 CFR Part 39
[Docket No. FAA-2019-0989; Product Identifier 2019-NM-097-AD]
RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directives (ADs)
2015-14-07, 2016-07-10, and 2016-24-09, which apply to The Boeing
Company Model 787-8 and 787-9 airplanes. ADs 2015-14-07, 2016-07-10,
and 2016-24-09 require actions related to certain flight control module
(FCM) software. Since the FAA issued these ADs, the agency has received
reports of unannunciated dual symmetric inboard slat skew and
deficiencies in the FCM software. This proposed AD would also require
installing flight control electronics (FCE) common block point 5 (CBP5)
software, which would terminate the existing requirements. The FAA is
proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by February
18, 2020.

Discussion
The FAA issued three ADs to address certain deficiencies in the FCM
software that, if not corrected, could prevent continued safe flight
and landing.
AD 2015-14-07, Amendment 39-18205 (80 FR 42014, July 16, 2015)
(``AD 2015-14-07''), applies to certain Model 787-8 airplanes. AD 2015-
14-07 requires installing certain FCM software, and resulted from
reports of deficiencies in the FCM software.
AD 2016-07-10, Amendment 39-18455 (81 FR 18741, April 1, 2016)
(``AD 2016-07-10''), applies to all Model 787-8 and 787-9 airplanes. AD
2016-07-10 requires revising the airplane flight manual (AFM) to
instruct the flightcrew to avoid abrupt flight control inputs in
response to sudden drops in airspeed, and to reinforce the need to
disconnect the autopilot before making any manual flight control
inputs. AD 2016-07-10 resulted from reports indicating that in certain
weather conditions with high moisture content or possible icing,
erroneous low airspeed may be displayed to the flightcrew before
detection and annunciation via engine indicating and crew-alerting
system (EICAS) messages.
AD 2016-24-09, Amendment 39-18726 (81 FR 86912, December 2, 2016)
(``AD 2016-24-09''), applies to all Model 787-8 and 787-9 airplanes. AD
2016-24-09 requires repetitive cycling of either the airplane
electrical power or the power to the three FCMs, and resulted from a
report indicating that all three FCMs might simultaneously reset if
continuously powered on for 22 days.
Actions Since ADs 2015-14-07, 2016-07-10, and 2016-24-09 Were Issued
The preambles to AD 2016-07-10 and AD 2016-24-09 explained that the
FAA considered the requirements ``interim action'' and were considering
further rulemaking. The FAA has now determined that further rulemaking
is indeed necessary, and this proposed AD follows from that
determination.
Since the FAA issued ADs 2015-14-07, 2016-07-10, and 2016-24-09,
the
[[Page 24]]
agency has received reports of unannunciated dual symmetric inboard
slat skew and deficiencies in the FCM software. An unannunciated dual
symmetric inboard slat skew can result in adverse handling
characteristics of the airplane.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Service Bulletin B787-81205-SB270039-00,
Issue 002, dated March 8, 2018. This service information describes
procedures for installing FCM loadable diagnostic information (LDI)
database (DB) and central maintenance computer function (CMCF) LDI DB
software.
The FAA also reviewed Boeing Alert Requirements Bulletin B787-
81205-SB270044-00 RB, Issue 001, dated December 18, 2018. This service
information describes procedures for installing FCE CBP5 software, and
applicable concurrent requirements (installing certain software).
The FAA also reviewed Boeing Service Bulletin B787-81205-SB310014,
Issue 002, dated June 14, 2017. This service information describes
procedures for installing new displays and crew alerting (DCA) system
and maintenance system (MS) software and doing a software check.
This proposed AD would also require Boeing Alert Service Bulletin
B787-81205-SB270017-00, Issue 001, dated September 18, 2013; Boeing
Alert Service Bulletin B787-81205-SB270020-00, Issue 002, dated
February 12, 2015; and Boeing Service Bulletin B787-81205-SB270023-00,
Issue 001, dated July 24, 2014; which the Director of the Federal
Register approved for incorporation by reference as of August 20, 2015
(80 FR 42017, July 16, 2015).
This proposed AD would also require Boeing Alert Service Bulletin
B787-81205-SB270040-00, Issue 001, dated November 25, 2016, which the
Director of the Federal Register approved for incorporation by
reference as of December 2, 2016 (81 FR 86912, December 2, 2016).
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
The FAA is proposing this AD because the agency 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 retain all of the requirements of AD 2016-
07-10 and AD 2016-24-09. This proposed AD would retain all of the
requirements of AD 2015-14-07, except paragraph (g)(3) of AD 2015-14-07
(installation of FCM Common Block Point 1 software), which was
erroneously included in AD 2015-14-07 and is therefore no longer
necessary. The service information specified in paragraph (g)(3) of AD
2015-14-07 applies only to Model 787-9 airplanes. This proposed AD
would also require accomplishing the actions specified in the service
information described previously, except as discussed under
``Difference Between this Proposed AD and the Service Information,''
and except for any differences identified as exceptions in the
regulatory text of this proposed AD. The new proposed requirements
would terminate all of the retained requirements.
For information on the procedures and compliance times, see this
service information at https://www.regulations.gov by searching for and
locating Docket No. FAA-2019-0989.
Difference Between This Proposed AD and the Service Information
Although Boeing Alert Requirements Bulletin B787-81205-SB270044-00
RB, Issue 001, dated December 18, 2018, recommends accomplishing the
software installation within 12 months, the FAA has determined that
this interval would not address the identified unsafe condition soon
enough to ensure an adequate level of safety for the affected fleet. In
developing an appropriate compliance time for this AD, the FAA
considered the manufacturer's recommendation, the degree of urgency
associated with the subject unsafe condition, and the average
utilization of the affected fleet. In light of these factors, the FAA
finds that a 6-month compliance time represents an appropriate interval
of time for affected airplanes to continue to operate without
compromising safety. This difference has been coordinated with Boeing.
Other Relevant Rulemaking
The concurrent requirements specified in this proposed AD are also
concurrent requirements for the actions required by AD 2019-08-05,
Amendment 39-19626 (84 FR 18707, May 2, 2019) (``AD 2019-08-05''), as
specified in paragraph (g)(2) of AD 2019-08-05.
Explanation of Requirements Bulletin
The FAA worked in conjunction with industry, under the
Airworthiness Directive Implementation Aviation Rulemaking Committee
(AD ARC), to enhance the AD system. One enhancement is a process for
annotating which steps in the service information are ``required for
compliance'' (RC) with an AD. Boeing has implemented this RC concept
into Boeing service bulletins.
In an effort to further improve the quality of ADs and AD-related
Boeing service information, a joint process improvement initiative was
worked between the FAA and Boeing. The initiative resulted in the
development of a new process in which the service information more
clearly identifies the actions needed to address the unsafe condition
in the ``Accomplishment Instructions.'' The new process results in a
Boeing Requirements Bulletin, which contains only the actions needed to
address the unsafe condition (i.e., only the RC actions).
Costs of Compliance
The FAA estimates that this proposed AD affects 78 airplanes of
U.S. registry.
The compliance time has passed for the retained requirements in
this proposed AD, so all affected airplanes should already be in
compliance with those requirements. Therefore, this AD imposes no
additional financial burden on any U.S. operator.
However, if a noncompliant airplane is imported and placed on the
U.S. Register in the future, the FAA estimates the following costs to
comply with the retained actions:
Estimated Costs for Retained Requirements
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Retained requirements of AD 2015-14[dash]07 4 work-hours x $85 per hour = $0 $340
(11 airplanes). $340.
Retained requirements of AD 2016-07-10........ 1 work-hour x $85 per hour = $85 0 85
[[Page 25]]
Retained requirements of AD 2016-24-09........ 1 work-hour x $85 per hour = $85 0 85
per cycle.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to comply with the new
requirements in this proposed AD:
Estimated Costs for New Requirements
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
New proposed software installation.... 2 work-hours x $85 per $0 $170 $13,260
hour = $170.
----------------------------------------------------------------------------------------------------------------
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.
The FAA is 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 proposed 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
The FAA has 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 that the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) 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:
