ACTION: Final rule. AGENCY: 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 motoroperated 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. SUMMARY: 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: khammond on DSK30JT082PROD with RULES 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 VerDate Sep<11>2014 19:54 Oct 10, 2018 Jkt 247001 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 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 51305 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 E:\FR\FM\11OCR1.SGM 11OCR1 51306 Federal Register / Vol. 83, No. 197 / Thursday, October 11, 2018 / Rules and Regulations 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.

In the past, E:\FR\FM\11OCR1.SGM 11OCR1 khammond on DSK30JT082PROD with RULES Federal Register / Vol. 83, No. 197 / Thursday, October 11, 2018 / Rules and Regulations 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 × $85 per work-hour). (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. 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. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: 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 VerDate Sep<11>2014 19:54 Oct 10, 2018 Jkt 247001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION: Discussion SUMMARY: DATES: Examining the AD Docket We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus SAS Model A350– 941 airplanes. The NPRM published in the Federal Register on May 15, 2018 (83 FR 22414). The NPRM was prompted by an inspection on the production line that revealed evidence of paint peeling on the forward and aft cargo frame forks around the hook bolt hole. The NPRM proposed to require a detailed visual inspection for any deficiency of the frame forks around the hook bolt hole on certain forward and aft cargo doors and applicable corrective actions. We are issuing this AD to address paint peeling on the forward and aft cargo doors that could develop into galvanic corrosion, which could lead to cargo door failure and possibly result in decompression of the airplane and injury to occupants. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0031, dated January 31, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A350–941 airplanes. The MCAI states: Following an inspection on the production line, paint peeling was found on forward and aft cargo door frame forks around the hook bolt hole. Subsequent investigations determined this had been caused by incorrect masking method during application of primer, top coat and Tartaric Sulfuric PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 51313 Anodizing (TSA) layer. As the cargo doors are located in an area with high corrosion sensitivity, where a surface protection with primer, top coat and TSA is specified, in case of paint peeling off, galvanic corrosion could develop. This condition, if not detected and corrected, could lead to cargo door failure, possibly resulting in decompression of the aeroplane and injury to occupants. To address this potential unsafe condition, Airbus identified the affected parts and issued the SB [Airbus Service Bulletin (SB) A350–52–P011, dated May 12, 2017] to provide inspection instructions. For the reasons described above, this [EASA] AD requires a one-time detailed [visual] inspection (DET) of the affected parts [for discrepancies] and, depending on findings, accomplishment of applicable corrective action(s) [i.e., restoration of the anti-corrosion protection of frame forks of affected parts]. You may examine the MCAI in the AD docket on the internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0410. Comments We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM or on the determination of the cost to the public. Clarification of Definition of Serviceable Part We have changed paragraph (g)(2) in this AD by adding that a serviceable part is also ‘‘a part identified as an affected part, and the actions in paragraph (i) of this AD have been accomplished on that part.’’ This change has been coordinated with EASA and Airbus. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for 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. Related Service Information Under 1 CFR Part 51 Airbus SAS has issued Airbus Service Bulletin A350–52–P011, dated May 12, 2017.

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.

fuel shutoff valve, in accordance with the Accomplishment 
Instructions of Boeing Special Attention Service Bulletin 757-28-
0138, Revision 1, dated June 19, 2017 (``SB 757-28-0138 R1''); or 
Boeing Service Bulletin 767-28-0115, Revision 1, dated June 2, 2016 
(``SB 767-28-0115 R1''); as applicable. A review of airplane 
maintenance records is acceptable in lieu of this inspection if the 
part number of the MOV actuator at each location can be conclusively 
determined from that review.

(h) Replacement

    (1) For Model 737-600, -700, -700C, -800, -900, and -900ER 
series airplanes on which any MOV actuator having P/N MA20A2027 or 
P/N MA30A1001 (Boeing P/N S343T003-56 or Boeing P/N S343T003-66, 
respectively), is found during the inspection required by paragraph
