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 airplanes. This AD was prompted by a 
report indicating that during an airplane inspection in production, the 
variable frequency starter generator (VFSG) power feeder cables were 
found to contain terminal lugs incorrectly installed common to terminal 
blocks located in the wing front spar. This AD requires a general 
visual inspection of the wings, section 16, terminal lugs at the 
terminal power block of the VFSG power feeder cable for correct 
installation and applicable corrective actions. We are issuing this AD 
to address the unsafe condition on these products.

DATES: This AD is effective June 27, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 27,

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 airplanes. The NPRM published in the Federal Register on 
December 16, 2016 (81 FR 91066) (``the NPRM''). The NPRM was prompted 
by a report indicating that during an airplane inspection in 
production, the VFSG power feeder cables were found to contain terminal 
lugs incorrectly installed common to terminal blocks located in the 
wing front spar. The NPRM proposed to require a general visual 
inspection of the wings, section 16, terminal lugs at the terminal 
power block of the VFSG power feeder cable for correct installation and 
applicable corrective actions. We are issuing this AD to detect and 
correct incorrectly installed terminal lugs which may contact adjacent 
structure and be damaged. Damaged terminal lugs could cause the 
potential loss of several functions essential for safe flight or 
electrical arcing in a flammable leakage zone, which could result in an 
electrical short and the possible introduction of energy into the main 
fuel tanks.

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, expressed support 
for the NPRM.

Request To Revise Compliance Time

    Boeing and All Nippon Airways (ANA) requested that we revise the 
compliance time specified in paragraph (g) of the proposed AD. Boeing 
stated that paragraph (g) of the proposed AD refers to paragraph 1.E., 
``Compliance,'' of Boeing Alert Service Bulletin B787-81205-SB240027-
00, Issue 002, dated September 6, 2016 (``ASB B787-81205-SB240027-00, 
Issue 002'') and requested that we instead refer to paragraph 5., 
``Compliance,'' of ASB B787-81205-SB240027-00, Issue 002'' because that 
is the correct location for the applicable times. ANA stated that 
paragraph 1.E., ``Compliance,'' doesn't exist in ASB B787-81205-
SB240027-00, Issue 002, and recommended a compliance time of ``within 
12 months after the effective date of this AD.'' Boeing also 
recommended that the compliance time be tied to the effective date of 
the AD to allow operators a valid and acceptable time frame to perform 
the actions specified in ASB B787-81205-SB240027-00, Issue 002. 
Additionally, the commenters stated that the compliance time ``within 
12 months after the original issue date of this service bulletin,'' as 
specified in ASB B787-81205-SB240027-00, Issue 002, would put operators 
out of compliance upon AD issuance.
    We agree with the commenters. We have revised paragraph (g) of this 
AD to specify ``Within 12 months after the effective date of this AD'' 
and have removed reference to paragraph 1.E., ``Compliance,'' of ASB 
B787-81205-SB240027-00, Issue 002. We have determined that extending 
the compliance time from what was proposed will provide an acceptable 
level of safety.

Request To Clarify the Unsafe Condition Statement

    Boeing requested that we revise the ``Discussion'' section of the 
NPRM and paragraph (e) of the proposed AD to remove information about 
the potential to introduce energy into the main fuel tanks and include 
information about

[[Page 23513]]

potential loss of systems. Boeing stated that ``introduction of energy 
into the fuel tank'' is possible but doesn't fully describe the unsafe 
condition. Boeing noted that the ``BACKGROUND'' and ``REASON'' 
statements of ASB B787-81205-SB240027-00, Issue 002, specifically 
include information that the unsafe condition is due to the ``potential 
loss of several functions essential for safe flight.''
    We agree that clarification of the unsafe condition statement is 
necessary. We have revised the ``Discussion'' section of this final 
rule, and paragraph (e) of this AD to state that the unsafe condition 
is due to the ``potential loss of several functions essential for safe 
flight.'' However, we have not removed information about the potential 
to introduce energy into the main fuel tanks, because that information 
also describes the potential unsafe condition.

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 correcting 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 ASB B787-81205-SB240027-00, Issue 002. The service 
information describes procedures for a general visual inspection of the 
right and left wing, section 16, VFSG power feeder cable terminal lugs 
for correct installation 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.

Costs of Compliance

    We estimate that this AD affects 6 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
               Action                         Labor cost            Parts cost        product        operators

                                      = $680.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
will be required based on the results of the inspection. We have no way 
of determining the number of aircraft that might need these repairs:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per

----------------------------------------------------------------------------------------------------------------
\1\ Labor costs are specific to each wing (left or right.)

    According to the manufacturer, some of the 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 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.

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.

generator (VFSG) power feeder cables were found to contain terminal 
lugs incorrectly installed common to terminal blocks located in the 
wing front spar; the lugs were close to the structure causing the 
lug sleeve to come in contact with adjacent fasteners. We are 
issuing this AD to detect and correct incorrectly installed terminal 
lugs which may contact adjacent structure and be damaged. Damaged 
terminal lugs could cause the potential loss of several functions 
essential for safe flight or electrical arcing in a flammable 
leakage zone, which could result in an electrical short and the 
possible introduction of energy into the main fuel tanks.

(f) Compliance

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

(g) Inspection of Terminal Lugs and Corrective Actions

    Within 12 months after the effective date of this AD, do a
