Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2015-09-07, 
which applied to all The Boeing Company Model 787 airplanes. AD 2015-
09-07 required a repetitive maintenance task for electrical power 
deactivation. This AD requires installing new software for the 
generator control unit (GCU). This AD also removes certain airplanes 
from the applicability. This AD was prompted by the determination that 
a Model 787 airplane that has been powered continuously for 248 days 
can lose all alternating current (AC) electrical power due to the GCUs 
simultaneously going into failsafe mode. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective November 20, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 20, 
2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of May 1, 
2015 (80 FR 24789, May 1, 2015).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2015-09-07, Amendment 39-18153 (80 FR 24789, 
May 1, 2015) (``AD 2015-09-07''). AD 2015-09-07 applied to all The 
Boeing Company Model 787 airplanes. The NPRM published in the Federal 
Register on August 15, 2017 (82 FR 38629). The NPRM was prompted by the 
determination that a Model 787 airplane that has been powered 
continuously for 248 days can lose all AC electrical power due to the 
GCUs simultaneously going into failsafe mode. This condition is caused 
by a software counter internal to the GCUs that will overflow after 248 
days of continuous power. The NPRM proposed to require installing the 
new GCU software developed to address the software counter overflow 
anomaly. The NPRM also proposed to remove certain airplanes from the 
applicability. We are issuing this AD to address loss of all AC 
electrical power, which could result in loss of control of the 
airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. 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) and American 
Airlines indicated their support for the NPRM.

Request To Update Number of Affected Airplanes

    Boeing requested that we update the Costs of Compliance section of 
the proposed AD to state that ``55 airplanes of U.S. registry'' are 
affected. Boeing noted that its records show 55 N-registered airplanes, 
not 47 as stated in the proposed AD.
    We agree with the commenter's request for the reason provided. We 
have updated the Costs of Compliance section of this AD accordingly.

Request To Revise Warranty Information in Costs of Compliance Section

    Boeing requested that we revise the Costs of Compliance section of 
the proposed AD to state that warranty remedies are not available for 
Boeing Service Bulletin B787-81205-SB240063-00, Issue 002, dated June 
7, 2016. Boeing noted that Boeing Service Bulletin B787-81205-SB240063-
00, Issue 002, dated June 7, 2016, states ``Boeing warranty remedies 
are not available for the configuration changes set forth in this 
service bulletin. Notwithstanding, Boeing will provide the supplier 
software referenced in this service bulletin at no charge. This offer 
will expire eight years from the original issue date of this service 
bulletin.''
    We acknowledge the commenter's request and agree to clarify. The 
warranty information in the Costs of Compliance section of this AD is 
meant to be informational, and is included when the manufacturer's 
service information states warranty coverage may be available. We do 
not control warranty coverage and operators must work with the 
manufacturer to determine if they are eligible for a warranty. We have 
revised the warranty information in the Costs of Compliance section of 
this AD to note that some of the software costs may be covered under 
warranty.

[[Page 52132]]

Request To Clarify Requirements Related to Software Installation

    Boeing requested that we clarify or confirm that requiring 
operators to concurrently install new software as specified in 
paragraph (i) of the proposed AD will not require operators to request 
alternative methods of compliance (AMOCs) for installing later-approved 
software revisions in accordance with future service bulletins. Boeing 
noted that Boeing Service Bulletin B787-81205-SB420006-00 includes 
instructions to install several software part numbers that will bring 
airplanes up to common interface control document (ICD) 9.3 
configuration, which is not a safety-related project. Boeing further 
noted that several other service bulletins call out common ICD 9.3 as a 
concurrent requirement.
    Based on the commenter's request, we have changed paragraphs (h), 
(i)(1)(i), (i)(1)(ii), and (i)(2) of this AD to allow operators to 
install later-approved software versions, provided those later-approved 
versions meet certain conditions. Therefore, operators will not be 
required to obtain AMOCs to install newer versions of the software 
required by paragraph (i) of this AD. Similarly, operators will not be 
required to obtain AMOCs to install newer versions of the software 
required by paragraph (h) of this AD.

Request To Provide Additional Credit

    Boeing and United Airlines (UAL) requested that we provide credit 
for certain actions done in accordance with Issue 002 of Boeing Service 
Bulletin B787-81205-SB420006-00. Boeing also requested that we provide 
credit for certain actions done in accordance with Issue 001 of Boeing 
Service Bulletin B787-81205-SB420006-00. UAL noted that it had 
accomplished Boeing Service Bulletin B787-81205-SB420006-00, Issue 002, 
dated February 13, 2015, on its fleet. UAL added that Boeing Service 
Bulletin B787-81205-SB420006-00, Issue 003, dated October 15, 2015, was 
issued to correct software part numbers for certain groups of 
airplanes, and none of those airplanes are in its fleet. Boeing noted 
that Issue 002 and Issue 003 of Boeing Service Bulletin B787-81205-
SB420006-00 were issued to provide clarification and to provide 
additional required work for a limited group of airplanes. Boeing 
suggested that we revise paragraph (j) of the proposed AD to provide 
credit for the earlier service bulletin revisions for certain airplanes 
and provide credit for the earlier revisions for certain other 
airplanes provided that additional work is done on those airplanes.
    We agree with the commenters' requests for the reasons provided. We 
have changed paragraphs (j)(1) and (j)(2) of this AD and added 
paragraph (j)(3) to this AD to provide credit for actions required by 
paragraphs (i)(1)(ii) and (i)(2) of this AD for certain airplanes.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD 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 AD.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service information.
     Boeing Service Bulletin B787-81205-SB240063-00, Issue 002, 
dated June 7, 2016, which describes procedures for installing 
operational program software (OPS) into each of the six GCUs and doing 
a software check. This service information specifies to concurrently 
accomplish the following two service bulletins.
     Boeing Service Bulletin B787-81205-SB280018-00, Issue 001, 
dated April 17, 2014, which describes procedures for installing fuel 
quantity management program software and doing a software check.
     Boeing Service Bulletin B787-81205-SB420006-00, Issue 003, 
dated October 15, 2015, which describes procedures for installing 
common interface control document 9.3 software and doing a software 
check.

April 19, 2015; and Boeing Multi Operator Message MOM-MOM-15-0248-
01B(R1), dated April 20, 2015. This service information describes 
procedures for electrical power deactivation of Model 787 airplanes. 
These documents are distinct due to editorial revisions.
    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.

Costs of Compliance

    We estimate that this AD affects 55 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

\1\ We have received no definitive data that would enable us to provide parts cost estimates for the concurrent
  actions specified in this AD.

    According to the manufacturer, some of the software costs of this 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all available costs in our 
cost estimate.

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

    We have determined that 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2015-09-07, Amendment 39-18153 (80 FR 24789, May 1, 2015), and adding 
the following new AD:

2018-20-15 The Boeing Company: Amendment 39-19449; Docket No. FAA-
2017-0771; Product Identifier 2016-NM-212-AD.

(a) Effective Date

    This AD is effective November 20, 2018.

(b) Affected ADs

    This AD replaces AD 2015-09-07, Amendment 39-18153 (80 FR 24789, 
May 1, 2015) (``AD 2015-09-07'').

(c) Applicability

    This AD applies to The Boeing Company Model 787-8 and 787-9 
airplanes, certificated in any category, as identified in Boeing 
Service Bulletin B787-81205-SB240063-00, Issue 002, dated June 7, 
2016.

(d) Subject

    Air Transport Association (ATA) of America Code 24, Electrical 
power.

(e) Unsafe Condition

    This AD was prompted by the determination that a Model 787 
airplane that has been powered continuously for 248 days can lose 
all alternating current (AC) electrical power due to the generator 
control units (GCUs) simultaneously going into failsafe mode. This 
condition is caused by a software counter internal to the GCUs that 
will overflow after 248 days of continuous power. We are issuing 
this AD to address loss of all AC electrical power, which could 
result in loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Repetitive Maintenance Task: Electrical Power Deactivation 
With a New Reference to Terminating Action

    This paragraph restates the actions required by paragraph (g) of 
AD 2015-09-07, with a new reference to terminating action. At the 
latest of the times specified in paragraphs (g)(1), (g)(2), and 
(g)(3) of this AD, accomplish electrical power deactivation on the 
airplane, in accordance with step 2) in ``DESIRED ACTION'' of Boeing 
Multi Operator Message MOM-MOM-15-0248-01B, dated April 19, 2015; or 
Boeing Multi Operator Message MOM-MOM-15-0248-01B(R1), dated April 
20, 2015. The main and auxiliary power unit (APU) batteries do not 
need to be disconnected when performing the electrical power 
deactivation. Repeat the electrical power deactivation thereafter at 
intervals not to exceed 120 days until the software installation 
required by paragraph (h) of this AD is done.
    (1) Within 120 days after the last electrical power deactivation 
in accordance with step 2) in ``DESIRED ACTION'' of Boeing Multi 
Operator Message MOM-MOM-15-0248-01B, dated April 19, 2015; or 
Boeing Multi Operator Message MOM-MOM-15-0248-01B(R1), dated April 
20, 2015.
    (2) Within 120 days after the date of issuance of the original 
certificate of airworthiness or the date of issuance of the original 
export certificate of airworthiness.
    (3) Within 7 days after May 1, 2015 (the effective date of AD 
2015-09-07).

(h) New Requirement of This AD: Software Installation

    Within 12 months after the effective date of this AD: Install 
new operational program software (OPS), or later-approved version, 
into each of the six GCUs, do a software check, and do all 
applicable corrective actions before further flight, in accordance 
with the Accomplishment Instructions of Boeing Service Bulletin 
B787-81205-SB240063-00, Issue 002, dated June 7, 2016.

    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
