SUPPLEMENTARY INFORMATION:

I. Background

    The Department of Labor, as part of its continuing effort to reduce
paperwork and respondent (i.e., employer) burden, conducts a
preclearance consultation

program to provide the public with an opportunity to comment on
proposed and continuing information collection requirements in
accordance with the Paperwork Reduction Act of 1995 (44 U.S.C.
3506(c)(2)(A)). This program ensures that information is in the desired
format, reporting burden (time and costs) is minimal, collection
instruments are clearly understood, and OSHA's estimate of the
information collection burden is accurate. The Occupational Safety and
Health Act of 1970 (the OSH Act) (29 U.S.C. 651 et seq.) authorizes
information collection by employers as necessary or appropriate for
enforcement of the OSH Act or for developing information regarding the
causes and prevention of occupational injuries, illnesses, and
accidents (29 U.S.C. 657). The OSH Act also requires that OSHA obtain
such information with minimum burden upon employers, especially those
operating small businesses, and to reduce to the maximum extent
feasible unnecessary duplication of efforts in obtaining information
(29 U.S.C. 657).
    Two construction standards, ``Medical Services and First Aid''
(Sec.  1926.50), and ``General Requirements for Storage'' (Sec.
1926.250), contain posting provisions. Paragraph (f) of Sec.  1926.50
requires employers to post emergency telephone numbers for physicians,
hospitals, or ambulances at the worksite if the 911 emergency telephone
service is not available; in the event a worker has a serious injury at
the worksite, this posting requirement expedites emergency medical
treatment of the employee. Paragraph (a)(2) of Sec.  1926.250 specifies
that employers must post the maximum safe load limits of floors located
in storage areas inside buildings or other structures, unless the
floors are on grade. This provision prohibits employers from
overloading floors in areas used to store material and equipment in
multi-story units that are under construction, thereby preventing the
floors from collapsing and seriously injuring workers.

II. Special Issues for Comment

    OSHA has a particular interest in comments on the following issues:
     Whether the proposed information collection requirements
are necessary for the proper performance of the Agency's functions to
protect workers, including whether the information is useful;
     The accuracy of OSHA's estimate of the burden (time and
costs) of the information collection requirements, including the
validity of the methodology and assumptions used;
     The quality, utility, and clarity of the information
collected; and
     Ways to minimize the burden on employers who must comply;
for example, by using automated or other technological information
collection and transmission techniques.

III. Proposed Actions

    OSHA is requesting that OMB extend its approval of the information
collection requirements contained in the two construction standards,
``Medical Services and First Aid'' paragraph (f) of Sec.  1926.50, and
``General Requirements for Storage'' paragraph (a)(2) of Sec.
1926.250. The Agency is requesting an adjustment decrease to its
current burden hour total from 197,819 to 139,078 for a total decrease
of 58,741 hours associated with these two Standards. The Agency will
summarize the comments submitted in response to this notice and will
include this summary in the request to OMB.
    Type of Review: Extension of a currently approved collection.
    Title: Construction Standards on the Posting of Emergency Telephone
Numbers and Floor Load Limits (29 CFR 1926.50(f) and 29 CFR
1926.250(a)(2)).
    OMB Number: 1218-0093.
    Affected Public: Business or other for-profits; Not-for-profit
institutions; Federal Government; State, Local or Tribal Governments.
    Number of Respondents: 282,050.
    Frequency: Varies from 2 minutes (.03 hour) to post emergency
numbers to 15 minutes (.25 hour) to develop and post load limits for
floors.
    Total Responses: 559,958.
    Estimated Total Burden Hours: 139,078.
    Estimated Cost (Operation and Maintenance): $0.

39-19535; AD 2018-26-05]
RIN 2120-AA64

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 777 airplanes. This AD was prompted by reports
of latently failed engine fuel shutoff spar valves discovered during
fuel filter replacement. This AD requires inspecting to determine the
part numbers (P/Ns) of the motor-operated valve (MOV) actuators at the
engine fuel shutoff spar valve positions, installing MOV actuators
having a certain acceptable part number or software if necessary, and
revising the maintenance or inspection program to add a new
airworthiness limitation. We are issuing this AD to address the unsafe
condition on these products.

DATES: This AD is effective February 1, 2019.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of February 1,
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 777 airplanes. The NPRM published in the Federal Register on
March 8, 2016 (81 FR 12039). The NPRM was prompted by reports of
latently failed engine fuel shutoff spar valves discovered during fuel
filter replacement. The NPRM proposed to require replacing certain MOV
actuators with MOV actuators having a certain acceptable part number on
both airline information management system (AIMS) Version 1- and 2-
equipped airplanes, or installing a newer software version on AIMS
Version 2-equipped airplanes.
    We issued a SNPRM to amend 14 CFR part 39 by adding an AD that
would apply to certain The Boeing Company Model 777 airplanes. The
SNPRM published in the Federal Register on August 21, 2017 (82 FR
39545). We issued the SNPRM to add a part number inspection, add an
AWL, and specify new AIMS software.
    We are issuing this AD to address latent failure of the fuel
shutoff spar valve to the engine, which could result in the inability
to terminate fuel flow to the engine and, in the case of an engine
fire, could lead to wing failure.

Comments

    We gave the public the opportunity to participate in developing
this final rule. The following presents the comments received on the
SNPRM and the FAA's response to each comment.

Request To Omit Inspection Requirement

    American Airlines (American) requested that we revise paragraph (g)
of the proposed AD (in the SNPRM) to omit the requirement to inspect
for the MOV actuator part numbers, and to reflect only the essential
compliance requirements as stated in paragraphs (g)(1) and (g)(2) of
the proposed AD (in the SNPRM) (the conditional requirements that
depend on the part number found). The commenter stated that the
inspection is not necessary to accomplish any of the compliance options
and adds no value to the process.
    We disagree with the request. The MOV actuator is a rotable part.
Several previously approved and existing interchangeable MOV actuator
part numbers may be installed at the engine fuel shutoff spar valve
positions. The MOV actuator installed at the engine fuel shutoff spar
valve positions at the time of airplane manufacture may have been later
replaced by an MOV actuator of a different part number. Because an
unsafe condition exists with certain part numbers, we have determined
that it is necessary to control the method by which an operator may
determine what part number is installed. In the absence of such a
control, an operator might simply assume that the part number delivered
with the airplane is still in place. The most positive method to verify
the installed part number is to inspect the part. Alternatively, as
stated in paragraph (g) of this AD, the FAA will accept verification
through a maintenance records check if the records positively show the
installed part number. We have not changed the AD regarding this issue.

Request To Incorporate AWL After MOV Actuator Installation

    American requested that we revise paragraph (g)(1) of the proposed
AD (in the SNPRM) to include incorporation of new airworthiness
limitation (AWL) 28-AWL-MOVA, which is specified in paragraph (h) of
the proposed AD (in the SNPRM).
    We disagree with the request. The commenter did not provide
rationale for the requested change, but we infer their request was to
have all required actions within paragraph (g) of this AD. We have
determined that it is better to structure the AD by separating required
actions that are discretely different into separate paragraphs. As
such, all required actions associated with inspecting and replacing the
affected MOV actuators are in paragraph (g) of this AD and all required
actions associated with the AWL revisions are in paragraph (h) of this
AD. Therefore, we find it unnecessary to change this AD regarding this
issue.

Request To Clarify Airplanes Subject to Inspection

    Cathay Pacific noted a discrepancy in Boeing Service Bulletin 777-
28A0034, Revision 3, dated September 25, 2015. Some airplanes that
subsequently installed AIMS-2 Block Point (BP) Version 17A software may
no longer match the conditions for the service bulletin groups, and do
not fit the criteria of either paragraph (g)(1) or (g)(2) of the
proposed AD (in the SNPRM). Cathay Pacific therefore requested that we
revise paragraph (g) of the proposed AD (in the SNPRM) to clarify that
the inspection is required only on airplanes without AIMS-2 BP Version
17A software. The commenter reported that Boeing confirmed that the
service bulletin will be revised to address this discrepancy.
    We agree with the request. We had intended to exclude the
inspection requirement for airplanes with AIMS-2 BP Version 17A
software installed. We have therefore revised paragraph (g) of this AD
to also state that no further action is required by paragraph (g) of
this AD if AIMS-2 BP Version 17 or later software is installed, which
also include AIMS-2 BP Versions 17.1 and 17A.

Request To Allow Alternative Service Information

    Delta Air Lines (Delta) requested that we revise paragraph
(g)(2)(ii) of the proposed AD (in the SNPRM) to allow Boeing Service
Bulletin 777-31-0275, dated June 8, 2017, as another method to use to
install AIMS-2 BP Version 17A software or later-approved version. Delta
explained that this service bulletin describes procedures for modifying
the hardware and software related to converting from AIMS-1 to AIMS-2
software, including AIMS-2 BP Version 17A software. Delta added that
Boeing Service Bulletin 777-31-0275 specifies installation of the same
software as that specified in Boeing Service Bulletin 777-31-0218, and
provides an equivalent level of safety to that of the SNPRM.
    We partially agree with the request. We agree that installation of
AIMS-2 BP Version 17A and later-approved software is an acceptable
alternative to replacing the MOV actuator, because that software allows
failure of any of the previously approved MOV actuator part numbers to
be detected and annunciated by the airplane display system. However, we
find it unnecessary to revise paragraph (g)(2)(ii) of this AD to add
another acceptable method of compliance (Boeing Service Bulletin 777-
31-0275) for the installation of AIMS-2 BP Version 17A software during
conversion of an airplane from AIMS-1 to AIMS-2 software. Instead, we
have revised paragraph (g) of this AD to clarify that no further action
is required by paragraph (g) of this AD if AIMS-2 BP Version 17 or
later software is installed.

Request To Provide Credit for AIMS-2 BP Version 17A Software

    American and Delta requested that we revise paragraph (j) of the
proposed AD (in the SNPRM) to provide credit for installation of AIMS-2
BP Version 17A software. Delta noted a conflict between the ``Actions
Since the NPRM was Issued'' section of the SNPRM (which specified the
proposed AD would require installing AIMS-2 BP Version 17A software)
and paragraph (j) of the proposed AD (in the SNPRM) (which

specified credit for paragraph (g)(2)(ii) when AIMS-2 BP Version 17 or
17.1 software was installed before the effective date of this AD).
    We agree to clarify that we have achieved similar results to the
commenters request since we have clarified the multiple references to
AIMS-2 BP Version 17 software in this AD, and that we have revised this
AD to exclude airplanes with AIMS-2 BP Version 17 or later software
installed from the requirements of paragraph (g) of this AD. Therefore,
we have not changed paragraph (j) and have determined that no further
change to the AD is necessary regarding this issue.

Request To Remove AWL Requirement

    Boeing requested that we revise paragraph (h) of the proposed AD
(in the SNPRM) to remove the requirement to incorporate the new AWL.
Boeing noted that paragraphs (g)(1) and (g)(2)(i) of the proposed AD
(in the SNPRM) would require inspection of all affected airplanes and
replacement of all MOV actuators at the engine fuel shutoff spar valve
positions with MOV actuators having P/N MA30A1017 (Boeing P/N S343T003-
76). Boeing asserted that those proposed requirements would therefore
be redundant with the proposed requirement of paragraph (h) of the
proposed AD (in the SNPRM), since the AWL prohibits installation of
MA20A2027 (Boeing P/N S343T003-56) and P/N MA30A1001 (Boeing P/N
S343T003-66) MOV actuators at the engine fuel shutoff spar valve
positions.
    We disagree with the request. As previously explained in the SNPRM,
the new AWL is necessary to prevent an airplane from being modified to
a pre-AD condition. Although the AWL would prohibit installation of the
MOV actuators at the engine fuel shutoff spar valve positions, these
two MOV actuator part numbers may still be installed at other locations
(as their failure in the other locations is of economic impact only),
and could be inadvertently re-installed at the engine fuel shutoff spar
valve positions. To address this concern, we added paragraph (h) to the
proposed AD (in the SNPRM) to specify the incorporation of the new AWL.
We have not changed this AD regarding this issue.

Request To Add Instructions for Maintenance Program Revision

    Delta recommended that we add details on how to conduct the
maintenance or inspection program, such as inspection methods and
repetitive intervals, in order to clarify the proposed requirements of
paragraph (h) of the proposed AD (in the SNPRM). That proposed
requirement would require revising the maintenance program to
incorporate a new airworthiness limitation prohibiting the installation
of certain MOV actuators, and to maintain this limitation in the
operator's fleet maintenance program. Delta inferred that the purpose
of the proposed requirement is to ensure that P/Ns MA30A1001 and
MA20A2027 are not installed in the two engine fuel shutoff spar valve
positions once the requirements of paragraph (g) of the AD have been
complied with.
    Delta stated that the requirement to incorporate a statement
indicating that a part is prohibited is not a maintenance program.
Delta stated that an aircraft maintenance program is not the
appropriate way to do this, adding that a ``parts prohibition''
statement (including locations--left and right engine fuel shutoff spar
valve positions, in this case) would be more appropriate to ensure that
a specific part number is not installed in the future. Delta stated
that similar parts prohibition statements are included in AD 2016-04-
20, Amendment 39-18414 (81 FR 10460, March 1, 2016), and AD 2013-05-03,
Amendment 39-17375 (78 FR 17290, March 21, 2013), such that operators
could then add notes to the airplane illustrated parts catalog (IPC),
aircraft maintenance manual (AMM), etc., to ensure that those parts are
not installed at the specified location in the future.
    We disagree with the request. An AWL containing a parts prohibition
statement for a maintenance or inspection program has been required by
other ADs, and is appropriate in this case. Paragraph (h) of this AD
requires only the incorporation of the AWL item into the operator's
fleet, not specific ways to accomplish the AWL task or comply with the
restriction. Each operator is responsible for accomplishing the AWL
task and maintaining the AWL restriction. Although a parts prohibition
statement could be included in the AD, we chose to mandate this
requirement via incorporation of an AWL to be consistent with the
requirements of AD 2015-19-01, Amendment 39-18264 (80 FR 55521,
September 16, 2015) (``AD 2015-19-01''). AD 2015-19-01 required
revising the existing maintenance or inspection program to include a
new AWL that required certain actions for The Boeing Company Model 777
airplanes with MOV actuators having P/N MA20A2027 or P/N MA30A1001
installed at the engine fuel shutoff spar valve positions. The
prohibited MOV actuator part numbers at the engine fuel shutoff spar
valve positions are still physically interchangeable with the
acceptable part numbers and may be used in other valve locations, and
they are expected to remain in operators' parts stores for a long
period of time. We have not changed this AD regarding this issue.

Request To Revise Compliance Time to Incorporate AWL

    Delta requested that we clarify the compliance time for
incorporating the new AWL into the maintenance program, as specified in
paragraph (h) of the proposed AD (in the SNPRM): 24 months after the
effective date of the AD, and after accomplishing the actions required
by (g). Delta recommended that the compliance time be changed to within
24 months after the effective date of the AD or after accomplishment of
the actions required by paragraph (g)(1) or (g)(2)(i) of the AD,
whichever occurs first. Delta also asked that we remove the condition
``after accomplishing the actions required by paragraph (g) of this AD
on all airplanes in an operator's fleet.'' Delta stated that the
current wording is unclear and appears to indicate operators must wait
until the actions of paragraph (g) of the AD are complete on their
Model 777 fleets before they can insert 28-AWL-MOVA into the
maintenance program. Delta believes the FAA's intent is to put in place
a part prohibition for MOV actuators at the engine fuel shutoff spar
valve positions on applicable airplanes without AIMS-2 BP Version 17
software or later version, and that when the requirements of paragraph
(g)(2)(ii) of the AD are completed, this AWL would no longer be
applicable.
    We agree with the request. We have revised the compliance time in
paragraph (h) of this AD to ``within 24 months after the effective date
of the AD.'' This allows operators to incorporate the new AWL into
their maintenance program at any time within that 24-month period,
without waiting until all required actions on all affected airplanes in
the fleet are completed. This would also allow continued operation of
an airplane if another airplane having the pre-AD configuration is
introduced into an operator's fleet before the end of the compliance
time, even if this were to occur after the accomplishment of the
required actions on all other airplanes in the fleet.

Request To Exclude Model 777F Series Airplanes

    FedEx requested that we exclude Model 777F series airplanes from
the proposed requirements of paragraphs (g), (h), and (i) of the
proposed AD (in the SNPRM). The service information,

Boeing Service Bulletin 777-28A0034, Revision 3, dated September 25,
2015, specifies that no work is necessary for airplanes in Group 7,
which includes Model 777F series airplanes.
    We disagree with the request. Even though the commenter is correct
in that Boeing Service Bulletin 777-28A0034, Revision 3, dated
September 25, 2015, specifies that no work is necessary for airplanes
in Group 7, which includes Model 777F series airplanes, the intent of
this AD is to ensure that all airplanes identified in paragraph (c) of
this AD, which includes Model 777F series airplanes and other Group 7
airplanes, address the unsafe condition through compliance with the
requirements of the AD. Compliance with the requirements of paragraph
(g) of this AD may be accomplished by installing a certain MOV actuator
in accordance with Boeing Service Bulletin 777-28A0034, Revision 3,
dated September 25, 2015, or installing certain AIMS-2 BP Version 17 or
later software in accordance with Boeing Service Bulletin 777-31-0218,
dated September 8, 2016 (depending on configuration).
    We have clarified the options available for some of the affected
airplanes, i.e., Group 7 airplanes with AIMS-2 BP Version 16 or earlier
software. Specifically, if the actions specified in paragraph (g)(2)(i)
of this AD are done, Figures 35 and 37 of Boeing Service Bulletin 777-
28A0034, Revision 3, dated September 25, 2015, can be used for
compliance regarding installation of the MOV actuator. Operators may
also install AIMS-2 BP Version 17A software in accordance with
paragraph (g)(2)(ii) of this AD. It is also necessary for operators of
affected Boeing Model 777F airplanes to incorporate the AWL
requirements specified in paragraph (h) of this AD.

Additional Changes to AD

    The effectivity of Boeing Service Bulletin 777-28A0034, Revision 3,
dated September 25, 2015, incorrectly categorizes airplanes in Group 4
as only those with AIMS-1 software installed. We have confirmed with
Boeing that Group 4 airplanes includes airplanes with AIMS-1 software
or AIMS-2 BP Version 16 or earlier software; or AIMS-2 BP Version 17 or
later software. The airplane variable number listing in the service
information does include the AIMS-2 equipped airplanes. We have
therefore clarified for the purposes of the requirements in paragraph
(g)(2) of this AD to state that Group 4, as identified in Boeing
Service Bulletin 777-28A0034, Revision 3, dated September 25, 2015,
includes airplanes with AIMS-1 software or AIMS-2 BP Version 16 or
earlier software installed.
    We have revised paragraph (i) in this AD to clarify that the
requirements of AD 2015-19-01 may be terminated only when the
requirements of paragraph (g) and (h) of this AD have been done on
``all affected airplanes in an operator's fleet.''

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
SNPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was
already proposed in the SNPRM.
    We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin 777-28A0034, Revision 3, dated
September 25, 2015. This service information describes procedures for,
among other things, inspection and replacement of the MOV actuators at
the engine fuel shutoff spar valve positions.
    We also reviewed Boeing Service Bulletin 777-31-0218, dated
September 8, 2016. This service information describes procedures for
installing the AIMS-2 BP Version 17A software upgrade.
    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 154 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                         Cost per
             Action                   Labor cost        Parts cost        product       Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspection......................  1 work-hour x $85               $0             $85  $13,090.
                                   per hour = $85.
Replacement of two MOV actuators  5 work-hours x $85          12,000          12,425  Up to $422,450.
 without fuel tank access.         per hour = $425.
Installation of AIMS-2 BP         7 work-hours x $85               0             595  Up to 71,400.
 Version 17A software.             per hour = $595.
----------------------------------------------------------------------------------------------------------------

    We have determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although we
recognize that this number may vary from operator to operator. In the
past, we have estimated that this action takes 1 work-hour per
airplane. Since operators incorporate maintenance or inspection program
changes for their affected fleets, we have determined that a per-
operator estimate is more accurate than a per-airplane estimate.
Therefore, we estimate the total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).

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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness
directive (AD):

2018-26-05 The Boeing Company: Amendment 39-19535; Docket No. FAA-
2016-4219; Product Identifier 2015-NM-169-AD.

(a) Effective Date

    This AD is effective February 1, 2019.

(b) Affected ADs

    This AD affects AD 2015-19-01, Amendment 39-18264 (80 FR 55521,
September 16, 2015) (``AD 2015-19-01'').

(c) Applicability

    This AD applies to The Boeing Company Model 777-200, 777-200LR,

category, excluding line numbers 1165 and subsequent.

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Unsafe Condition

    This AD was prompted by reports of latently failed engine fuel
shutoff spar valves discovered during fuel filter replacement. We
are issuing this AD to address latent failure of the fuel shutoff
spar valve to the engine, which could result in the inability to
terminate fuel flow to the engine and, in the case of an engine
fire, could lead to wing failure.

(f) Compliance

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

(g) Inspection and Replacement

    Within 24 months after the effective date of this AD: Do an
inspection to determine the part numbers (P/Ns) of the motor-
operated valve (MOV) actuators at the fuel shutoff spar valve
positions for the left and right engines, in accordance with the
Accomplishment Instructions of Boeing Service Bulletin 777-28A0034,
Revision 3, dated September 25, 2015. A review of airplane
maintenance records is acceptable in lieu of this inspection if the
part numbers can be conclusively determined from that review. If it
can be definitively determined, by visual inspection or airplane
maintenance records review, that P/N MA30A1017 (Boeing P/N S343T003-
76) is installed, or that airplane information management system
(AIMS) 2 Block Point (BP) Version 17 or later software is installed,
no further action is required by paragraph (g) of this AD.
    (1) For any MOV actuator with a P/N other than P/N MA30A1017
(Boeing P/N S343T003-76) on an airplane having AIMS-1 installed:
Within 24 months after the effective date of this AD, install MOV
actuators having part number (P/N) MA30A1017 at the engine fuel
shutoff spar positions, in accordance with the Accomplishment
Instructions of Boeing Service Bulletin 777-28A0034, Revision 3,
dated September 25, 2015.
    (2) For any MOV actuator with a P/N other than P/N MA30A1017
(Boeing P/N S343T003-76) on an airplane having AIMS-2 BP Version 16
software or earlier version, installed: Within 24 months after the
effective date of this AD, do the actions specified in paragraph
(g)(2)(i) or (g)(2)(ii) of this AD. For purposes of this AD,
