DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2017–0127; Product Identifier 2016–NM–161–AD; Amendment 39–19447; AD 2018–20–13] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. 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: 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 PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 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. Republication Editorial Note: Rule document 2018–21460 was originally published on pages 51304 through 51313 in the issue of Thursday, October 11, 2018. In that publication, on page 51307, in the second column, in (c)(1), ‘‘Estimated –200’’ should read ‘‘–200’’. The corrected document is published here in its entirety. 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 E:\FR\FM\17OCR1.SGM 17OCR1 52306 Federal Register / Vol. 83, No. 201 / Wednesday, October 17, 2018 / Rules and Regulations daltland on DSKBBV9HB2PROD with RULES (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 VerDate Sep<11>2014 16:09 Oct 16, 2018 Jkt 247001 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 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, PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 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 E:\FR\FM\17OCR1.SGM 17OCR1 Federal Register / Vol. 83, No. 201 / Wednesday, October 17, 2018 / Rules and Regulations burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 We reviewed the following service information. • Boeing Service Bulletin 737–28– 1314, dated November 17, 2014, describes procedures for installing new MOV actuators of the fuel shutoff valves for the left and right engines on Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. • Boeing 737–600/700/700C/800/900/ 900ER Special Compliance Items/ Airworthiness Limitations, D626A001– 9–04, Revision June 2018, describes AWLs for fuel tank ignition prevention on Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. • Boeing Special Attention Service Bulletin 757–28–0138, Revision 1, dated June 19, 2017, describes procedures for installing new MOV actuators of the fuel shutoff valves for the left and right engines, and of the APU fuel shutoff valve, on Model 757 airplanes. • Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D622N001–9, Revision May 2018, describes AWLs for fuel tank ignition prevention on Model 757 airplanes. • Boeing Service Bulletin 767–28– 0115, Revision 1, dated June 2, 2016, describes procedures for installing new MOV actuators of the fuel shutoff valves for the left and right engines, and of the 52307 APU fuel shutoff valve, on Model 767 airplanes. • Boeing 767–200/300/300F/400 Special Compliance Items/ Airworthiness Limitations, D622T001– 9–04, Revision March 2018, describes AWLs for fuel tank ignition prevention on Model 767 airplanes. 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 2,557 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Inspection and replacement Model 737 (1,440 airplanes). Inspection and replacement Model 757 (675 airplanes). Inspection and replacement Model 767 (442 airplanes). Labor cost Parts cost Cost per product Up to 6 work-hours × $85 per hour = Up to $510. Up to $12,000 ................... Up to $12,510 ................... Up to $18,014,400. Up to 9 work-hours × $85 per hour = Up to $765. Up to $18,000 ................... Up to $18,765 ................... Up to $12,666,375. Up to 9 work-hours × $85 per hour = Up to $765. Up to $18,000 ................... Up to $18,765 ................... Up to $8,294,130. daltland on DSKBBV9HB2PROD with RULES 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, 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). 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 VerDate Sep<11>2014 16:09 Oct 16, 2018 Jkt 247001 for practices, methods, and procedures the Administrator finds necessary for safety in air commerce.

ACTION: Final order. The Food and Drug Administration (FDA or we) is classifying the herpes virus nucleic acid-based cutaneous and mucocutaneous lesion panel into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the herpes virus nucleic acid-based cutaneous and mucocutaneous lesion panel’s classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients’ access to beneficial innovative devices, in part by reducing regulatory burdens. DATES: This order is effective October 17, 2018. The classification was applicable on May 13, 2014. FOR FURTHER INFORMATION CONTACT: Scott McFarland, Center for Devices and Radiological Health, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 66, Rm. 4676, Silver Spring, MD, 20993–0002, 301–796–6217, scott.mcfarland@fda.hhs.gov. SUPPLEMENTARY INFORMATION: daltland on DSKBBV9HB2PROD with RULES SUMMARY: I. Background Upon request, FDA has classified the herpes virus nucleic acid-based cutaneous and mucocutaneous lesion panel as class II (special controls), which we have determined will provide VerDate Sep<11>2014 16:09 Oct 16, 2018 Jkt 247001 a reasonable assurance of safety and effectiveness. In addition, we believe this action will enhance patients’ access to beneficial innovation, in part by reducing regulatory burdens by placing the device into a lower device class than the automatic class III assignment. The automatic assignment of class III occurs by operation of law and without any action by FDA, regardless of the level of risk posed by the new device. Any device that was not in commercial distribution before May 28, 1976, is automatically classified as, and remains within, class III and requires premarket approval unless and until FDA takes an action to classify or reclassify the device (see 21 U.S.C. 360c(f)(1)). We refer to these devices as ‘‘postamendments devices’’ because they were not in commercial distribution prior to the date of enactment of the Medical Device Amendments of 1976, which amended the Federal Food, Drug, and Cosmetic Act (FD&C Act). FDA may take a variety of actions in appropriate circumstances to classify or reclassify a device into class I or II. We may issue an order finding a new device to be substantially equivalent under section 513(i) of the FD&C Act (21 U.S.C. 360c(i) to a predicate device that does not require premarket approval. We determine whether a new device is substantially equivalent to a predicate by means of the procedures for premarket notification under section 510(k) of the FD&C Act (21 U.S.C. 360(k)) and part 807 (21 CFR part 807). FDA may also classify a device through ‘‘De Novo’’ classification, a common name for the process authorized under section 513(f)(2) of the FD&C Act. Section 207 of the Food and Drug Administration Modernization Act of 1997 (Pub. L. 105–115) established the first procedure for De Novo classification. Section 607 of the Food and Drug Administration Safety and Innovation Act (Pub. L. 112–144) modified the De Novo application process by adding a second procedure. A device sponsor may utilize either procedure for De Novo classification. Under the first procedure, the person submits a 510(k) for a device that has not previously been classified. After receiving an order from FDA classifying the device into class III under section 513(f)(1) of the FD&C Act, the person then requests a classification under section 513(f)(2). Under the second procedure, rather than first submitting a 510(k) and then a request for classification, if the person determines that there is no legally marketed device upon which to base a determination of substantial equivalence, that person requests a PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 52313 classification under section 513(f)(2) of the FD&C Act. Under either procedure for De Novo classification, FDA is required to classify the device by written order within 120 days. The classification will be according to the criteria under section 513(a)(1) of the FD&C Act. Although the device was automatically placed within class III, the De Novo classification is considered to be the initial classification of the device. We believe this De Novo classification will enhance patients’ access to beneficial innovation, in part by reducing regulatory burdens. When FDA classifies a device into class I or II via the De Novo process, the device can serve as a predicate for future devices of that type, including for 510(k)s (see 21 U.S.C. 360c(f)(2)(B)(i)). As a result, other device sponsors do not have to submit a De Novo request or premarket approval application (PMA) to market a substantially equivalent device (see 21 U.S.C. 360c(i), defining ‘‘substantial equivalence’’). Instead, sponsors can use the less-burdensome 510(k) process, when necessary, to market their device. II. De Novo Classification For this device, FDA issued an order on February 7, 2014, finding the LyraTM Direct HSV 1 + 2/VZV Assay not substantially equivalent to a predicate not subject to PMA. Thus, the device remained in class III in accordance with section 513(f)(1) of the FD&C Act when we issued the order. On February 21, 2014, Quidel Corporation submitted a request for De Novo classification of the LyraTM Direct HSV 1 + 2/VZV Assay. FDA reviewed the request in order to classify the device under the criteria for classification set forth in section 513(a)(1) of the FD&C Act. We classify devices into class II if general controls by themselves are insufficient to provide reasonable assurance of safety and effectiveness, but there is sufficient information to establish special controls that, in combination with the general controls, provide reasonable assurance of the safety and effectiveness of the device for its intended use (see 21 U.S.C. 360c(a)(1)(B)). After review of the information submitted in the request, we determined that the device can be classified into class II with the establishment of special controls. FDA has determined that these special controls, in addition to general controls, will provide reasonable assurance of the safety and effectiveness of the device. Therefore, on May 13, 2014, FDA issued an order to the requestor classifying the device into class II. FDA E:\FR\FM\17OCR1.SGM 17OCR1

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.

Republication

    Editorial Note: Rule document 2018-21460 was originally 
published on pages 51304 through 51313 in the issue of Thursday, 
October 11, 2018. In that publication, on page 51307, in the second 
column, in (c)(1), ``Estimated -200'' should read ``-200''. The 
corrected document is published here in its entirety.

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

[[Page 52306]]

(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 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

[[Page 52307]]

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
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
             Action                   Labor cost          Parts cost       Cost per product        operators
----------------------------------------------------------------------------------------------------------------
Inspection and replacement Model  Up to 6 work-hours  Up to $12,000.....  Up to $12,510.....  Up to $18,014,400.
 737 (1,440 airplanes).            x $85 per hour =
                                   Up to $510.
Inspection and replacement Model  Up to 9 work-hours  Up to $18,000.....  Up to $18,765.....  Up to $12,666,375.
 757 (675 airplanes).              x $85 per hour =
                                   Up to $765.
Inspection and replacement Model  Up to 9 work-hours  Up to $18,000.....  Up to $18,765.....  Up to $8,294,130.
 767 (442 airplanes).              x $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, 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.
