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 all The
Boeing Company Model 737 airplanes, excluding Model 737-100, -200, -
200C, -300, -400, and -500 series airplanes; all Model 757-200, -200PF,
-200CB, and -300 series airplanes; and all Model 767-200, -300, -300F,
and -400ER series airplanes. This AD was prompted by reports of
latently failed motor-operated valve (MOV) actuators of the fuel
shutoff valves. This AD requires replacing certain MOV actuators of the
fuel shutoff valves for the left and right engines (on certain
airplanes) and of the auxiliary power unit (APU) fuel shutoff valve (on
Model 757 and Model 767 airplanes); and revising the maintenance or
inspection program to incorporate certain airworthiness limitations
(AWLs). We are issuing this AD to address the unsafe condition on these
products.
DATES: This AD is effective November 15, 2018.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of November 15,
2018.

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 all The Boeing Company
Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes;
Model 757 airplanes; and Model 767 airplanes. The NPRM published in the
Federal Register on March 9, 2017 (82 FR 13073). The NPRM was prompted
by reports of latently failed MOV actuators of the fuel shutoff valves.
The NPRM proposed to require replacing certain MOV actuators of the
fuel shutoff valves for the left and right engines (on all airplanes)
and of the APU fuel shutoff valve (on Model 757 and Model 767
airplanes); and revising the maintenance or inspection program, as
applicable, to incorporate certain AWLs.
We subsequently issued a supplemental NPRM (SNPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all Model 737 airplanes,
excluding Model 737-100, -200, -200C, -300, -400, and -500 series
airplanes; and all Model 757 and 767 airplanes. The SNPRM published in
the Federal Register on April 3, 2018 (83 FR 14207). The SNPRM proposed
to add Model 737-8 airplanes and future Model 737 airplanes to the
applicability.
We are issuing this AD to address a latent failure of the actuator
for the engine or APU fuel shutoff valves, which could result in the
inability to shut off fuel to the engine or the APU, and, in case of
certain engine or APU fires, could result in structural 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 Exclude Model 737-8 and Future Model 737
Boeing requested that we revise the proposed AD (in the SNPRM) to
exclude Model 737-8 airplanes and future Model 737 airplanes, because
MOV actuator part number MA30A1017 (Boeing P/N S343T003-76) is the only
certified MOV actuator for use on any future Model 737 airplanes as
documented in the drawings and Illustrated Parts Catalog (IPC). The
commenter stated that using airworthiness limitations to prohibit the
use of parts with AD restrictions on one minor model series (Model 737
next generation (NG) airplanes) from being used on a different minor
model series (Model 737-8 and future Model 737 airplanes) that does not
allow the use of the restricted parts is unnecessary and implies that
certified configurations and ADs can be overridden via an Advisory
Circular (AC) or other means.
We disagree with the commenter's request. The MOV actuator
currently allowed on Model 737-8 and 737-9 airplanes, part number
MA30A1017 (Boeing P/N S343T003-76), is the only part number
certificated on those models, as documented in the manufacturer's
drawings. However, manufacturer's proprietary drawings are not readily
available to all affected operators, and there is no prohibition
against installing MOV actuator part numbers that were determined
unsafe in this AD. We have been informed by operators that the practice
of rotating physically interchangeable parts among airplanes is
widespread, and even a key part of their operations. In the absence of
an AD or AWL that restricts the installation of the affected parts, we
cannot be assured that the unsafe condition will not be introduced to
Model 737-8, 737-9, and future 737 airplanes. In addition, ACs are
advisory in nature and do not include mandatory actions. Therefore, ACs
do not take precedence over ADs. We have not changed this AD regarding
this issue.
Request To Remove Requirement To Revise Maintenance Program
Boeing requested that we remove paragraph (j) of the proposed AD
and revise FAA AC 120-77 or other applicable advisory material to
preclude installation of equipment that both Boeing and the FAA have
determined cause a potential safety issue, against certified
configurations. Boeing suggested that listing parts that are not
approved for use on a given model sets a precedent that can become
unmanageable, and that identifying parts that are acceptable for a
given airplane and installation position is a more explicit and
manageable approach. Boeing added that the use of AWLs to prohibit AD-
driven part installations is unnecessary and implies that certified
configurations and ADs can be overridden via an AC or other means.
We disagree with the commenter's request. The FAA is currently
considering revising AC 120-77 to help prevent the rotation of parts as
a minor alteration. However, ACs are advisory in nature and do not
include mandatory actions. Therefore, ACs cannot prohibit the
installation of unsafe equipment, and they do not take precedence over
ADs. In addition, the practice of rotating parts is widespread, and
revising the AC will not improve the situation in a timely manner.
Certain MOV actuator part numbers have been identified to be unsafe for
installation at certain locations. Since those part numbers continue to
be available and acceptable for installation at certain other
locations, we consider the use of AWLs to prohibit specific parts
installation to be a reasonable way to address the safety concern in a
timely manner. We have not changed this AD regarding this issue.
Request To Clarify Affected Part Numbers
FedEx requested that we revise paragraphs (h)(2) and (h)(3) of the
proposed AD (in the SNPRM) to state that no replacement is necessary if
the MOV actuator part number is one of the following alternative part
numbers: AV-31-1 (Boeing P/N S343T003-111), MA11A1265 (Boeing P/N
S343T003-14), or MA11A1265-1 (Boeing P/N S343T003-41). FedEx stated
that the service information specified in paragraphs (h)(2) and (h)(3)
of the proposed AD (in the SNPRM) explicitly state that those
alternative MOV actuator part numbers are acceptable substitutes for P/
N MA30A1017 (Boeing P/N S343T003-76).
We disagree with the commenter's request. However, we agree to
clarify the requirements of paragraphs (h)(2) and (h)(3) of this AD.
Paragraphs (h)(2) and (h)(3) of this AD require replacement of MOV
actuator P/N MA20A2027 (Boeing P/N S343T003-56) and P/N MA30A1001
(Boeing P/N S343T003-66) with an acceptable MOV actuator part number.
Those paragraphs do not state or imply that MOV actuator P/N AV-31-1
(Boeing P/N S343T003-111), P/N MA11A1265 (Boeing P/N S343T003-14), or
P/N MA11A1265-1 (Boeing P/N S343T003-41) must be replaced. Therefore,
we consider that adding the
[[Page 51306]]
proposed statement is unnecessary. We have not changed this AD
regarding this issue.
Request To Add a Terminating Action Provision
FedEx requested that we revise paragraphs (i)(2) and (i)(3) of the
proposed AD (in the SNPRM) to state that the actuator installation
would terminate the daily functional checks required by AWLs 28-AWL-ENG
and 28-AWL-APU. The commenter added that installation of MOV actuator
part number MA30A1017 (Boeing P/N S343T003-76) or an acceptable
alternative part number should substantially increase the safety value.
We disagree with the commenter's request. We have determined that
accomplishing the applicable maintenance or inspection program
revisions specified in paragraph (j) of this AD are the appropriate
terminating actions. As discussed previously in the preamble of the
SNPRM, we included the conditions (accomplishing the applicable
maintenance or inspection program revisions) that would terminate the
requirements of AD 2015-21-10, Amendment 39-18303 (80 FR 65130, October
26, 2015); AD 2015-19-04, Amendment 39-18267 (80 FR 55505, September
16, 2015); and AD 2015-21-09, Amendment 39-18302 (80 FR 65121, October
26, 2015). Those ADs require incorporation of the AWLs that require
repetitive inspections of specific MOV actuator part numbers installed
at specific locations. The requirements of those ADs may be terminated
if the applicable conditions specified in paragraph (m) of this AD are
met. We have not changed this AD regarding this issue.
Request To Refer to Latest Service Information
Southwest Airlines requested that we refer to the latest revisions
of the airworthiness limitations documents.
We agree with the commenter's request and have revised this AD to
refer to the current airworthiness limitations as the appropriate
source of service information, and have included earlier revisions of
the service information as credit in this AD. There are no changes to
the required actions of this AD because the tasks that must be
incorporated into the maintenance or inspection program are not changed
in Boeing 737-600/700/700C/800/900/900ER Special Compliance Items/
Airworthiness Limitations, D626A001-9-04, Revision June 2018; Boeing
757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness
Limitations (AWLS) and Certification Maintenance Requirements (CMRs),
D622N001-9, Revision May 2018; or Boeing 767-200/300/300F/400 Special
Compliance Items/Airworthiness Limitations, D622T001-9-04, Revision
March 2018; except for Task 28-AWL-23 for Model 767-200, -300, -300F,
and -400ER series airplanes, which adds instructions that further
describe the conditions for performing electrical bonding resistance
measurements, in addition to being more descriptive regarding cap seal
application.
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.

Costs of Compliance
We estimate that this AD affects 2,557 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspection and replacement Model Up to 6 work-hours x Up to $12,000................. Up to $12,510................. Up to $18,014,400.
737 (1,440 airplanes). $85 per hour = Up to
$510.
Inspection and replacement Model Up to 9 work-hours x Up to $18,000................. Up to $18,765................. Up to $12,666,375.
757 (675 airplanes). $85 per hour = Up to
$765.
Inspection and replacement Model Up to 9 work-hours x Up to $18,000................. Up to $18,765................. Up to $8,294,130.
767 (442 airplanes). $85 per hour = Up to
$765.
--------------------------------------------------------------------------------------------------------------------------------------------------------
For the maintenance/inspection program revision, we have determined
that this action takes an average of 90 work-hours per operator,
although we recognize that this number may vary from operator to
operator. In the past,
[[Page 51307]]
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.
