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

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.
