The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2017–0127; Directorate Identifier 2016–NM–161–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes; Model 757 airplanes; and Model 767 airplanes. This proposed AD was prompted by reports of latently failed motor operated valve (MOV) actuators of the fuel shutoff valves. This proposed AD would require replacing certain MOV actuators of the fuel shutoff valves for the left and right engines (all airplanes) and of the auxiliary power unit (APU) fuel shutoff valve (Model 757 and Model 767 airplanes); and revising the maintenance or inspection program, as applicable, to incorporate certain airworthiness limitations (AWLs).

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We have received reports of latently failed MOV actuators of the fuel shutoff valves, due to the design of the valve actuator, discovered during fuel filter or engine replacement. The MOV actuator failed to close the valve when commanded and failed to indicate the failure to close the valve. Certain component failure modes within the MOV actuator could result in simultaneous loss of valve control and indication. A latent failure of the MOV actuator for the engine or APU fuel shutoff valve 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. Related ADs We recognize there are requirements in AD 2008–06–03, Amendment 39– 15415 (73 FR 13081, March 12, 2008), and AD 2009–22–13, Amendment 39– 16066 (74 FR 55755, October 29, 2009), that might appear to conflict with the requirements of this proposed AD. However, alternative methods of compliance (AMOCs) have already been issued for those ADs to allow installation of the MOV actuators that are required for compliance with this proposed AD. Those AMOCs preclude any potential conflicts between ADs. No new AMOC is needed for this proposed AD regarding this issue. AD 2015–21–09, Amendment 39– 18302 (80 FR 65121, October 26, 2015) (‘‘AD 2015–21–09’’), which applies to Model 767 airplanes, was prompted by reports of latently failed MOV actuators of the fuel shutoff valves discovered during fuel filter replacement. AD 2015– 21–09 requires revising the maintenance or inspection program to include new AWLs. AD 2015–19–04, Amendment 39– 18267 (80 FR 55505, September 16, 2015), which applies to Model 757 airplanes was prompted by reports of E:\FR\FM\09MRP1.SGM 09MRP1 13074 Federal Register / Vol. 82, No. 45 / Thursday, March 9, 2017 / Proposed Rules jstallworth on DSK7TPTVN1PROD with PROPOSALS latently failed MOV actuators of the fuel shutoff valves discovered during fuel filter replacement. This AD requires revising the maintenance or inspection program to include new AWLs. AD 2015–21–10, Amendment 39– 18303 (80 FR 65130, October 26, 2015), which applies to Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes was prompted by reports of latently failed MOV actuators of the fuel shutoff valves discovered during fuel filter replacement. This AD requires revising the maintenance or inspection program to include a new AWL. AD 2016–04–20, Amendment 39– 18414 (81 FR 10460, March 1, 2016) (‘‘AD 2016–04–20’’), which applies to Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes, Model 757 airplanes, Model 767 airplanes, and Model 777 airplanes, resulted from fuel system reviews conducted by the manufacturer. This AD requires an inspection to determine if certain MOV actuators for the fuel tanks or fuel feed system are installed on the airplane, and replacement of any affected actuators. Airworthiness Limitations Based on Type Design The FAA recently became aware of an issue related to the applicability of ADs that require incorporation of the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) into an operator’s maintenance or inspection program. U.S. operators must operate their airplanes in an airworthy condition, in accordance with 14 CFR 91.7(a). Included in this obligation is the requirement to perform any maintenance or inspections specified in the ALS, and in accordance with the ALS as specified in 14 CFR 43.16 and 91.403(c), unless an alternative has been approved by the FAA. When a type certificate is issued for a type design, the specific ALS, including its revision level, is part of that type design, as specified in 14 CFR 21.31(c). The sum effect of these operational and maintenance requirements is an obligation to comply with the ALS revision defined in the type design referenced in the manufacturer’s conformity statement. This obligation may introduce a conflict with an AD if the AD requires a specific ALS revision for new airplanes that are delivered with a later ALS revision as part of their type design. The FAA has approved AMOCs that allow operators to incorporate the most recent ALS revision into their maintenance/inspection programs, in VerDate Sep<11>2014 14:52 Mar 08, 2017 Jkt 241001 lieu of the ALS revision required by the AD. This enables the operator to comply with both the AD and the type design. However, compliance with AMOCs is normally optional, and we recently became aware that some operators choose to retain the AD-mandated ALS revision in their fleet-wide maintenance/inspection programs, including those for new airplanes delivered with later ALS revisions, to help standardize the maintenance of the fleet. To ensure that operators comply with the applicable ALS revision for newly delivered airplanes containing a later revision than that specified in an AD, we plan to mandate the latest ALS revision as of the effective date of an AD, if we are to mandate a specific ALS revision, and limit the applicability of such AD actions to those airplanes to which the latest or earlier ALS revisions are applicable as of the effective date of that AD. This proposed AD therefore mandates the latest ALS revision as of the effective date of the AD for Model 737– 600, –700, –700C, –800, –900, and –900ER series airplanes, Model 757 airplanes, and Model 767 airplanes with an original certificate of airworthiness or original export certificate of airworthiness that was issued on or before the effective date of this proposed AD. Operators of airplanes with an original certificate of airworthiness or original export certificate of airworthiness issued after that date must comply with the airworthiness limitations specified as part of the approved type design.

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. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this Proposed AD and the Service Information.’’ For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0127. This proposed AD also requires revisions to certain operator maintenance documents to include new actions (e.g., inspections) and Critical Design Configuration Control Limitations (CDCCLs) described in the ALS of the ICA. Compliance with these E:\FR\FM\09MRP1.SGM 09MRP1 13075 Federal Register / Vol. 82, No. 45 / Thursday, March 9, 2017 / Proposed Rules actions and CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an AMOC according to paragraph (l) of this proposed AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. Costs of Compliance We estimate that this proposed AD affects 2,557 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Inspection and replacement Boeing 737 (1,440 airplanes). Inspection and replacement Boeing 757 (675 airplanes). Inspection and replacement Boeing 767 (442 airplanes). Maintenance or inspection program revision (2,557 airplanes). jstallworth on DSK7TPTVN1PROD with PROPOSALS Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, part A, Subpart III, Section 44701: ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and VerDate Sep<11>2014 14:52 Mar 08, 2017 Parts cost Cost per product Cost on U.S. operators × $85 per Up to $12,000 Up to $12,510 Up to $18,014,400. × $85 per Up to $18,000 Up to $18,765 Up to $12,666,375. × $85 per Up to $18,000 Up to $18,765 Up to $8,294,130. hour = $85 $0 ................... $85 ................. $217,345.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER 
series airplanes; Model 757 airplanes; and Model 767 airplanes. This 
proposed AD was prompted by reports of latently failed motor operated 
valve (MOV) actuators of the fuel shutoff valves. This proposed AD 
would require replacing certain MOV actuators of the fuel shutoff 
valves for the left and right engines (all airplanes) and of the 
auxiliary power unit (APU) fuel shutoff valve (Model 757 and Model 767 
airplanes); and revising the maintenance or inspection program, as 
applicable, to incorporate certain airworthiness limitations (AWLs). We 
are proposing this AD to address the unsafe condition on these 
products.

DATES: We must receive comments on this proposed AD by April 24, 2017.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2017-0127; 
Directorate Identifier 2016-NM-161-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    We have received reports of latently failed MOV actuators of the 
fuel shutoff valves, due to the design of the valve actuator, 
discovered during fuel filter or engine replacement. The MOV actuator 
failed to close the valve when commanded and failed to indicate the 
failure to close the valve. Certain component failure modes within the 
MOV actuator could result in simultaneous loss of valve control and 
indication. A latent failure of the MOV actuator for the engine or APU 
fuel shutoff valve 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.

Related ADs

    We recognize there are requirements in AD 2008-06-03, Amendment 39-
15415 (73 FR 13081, March 12, 2008), and AD 2009-22-13, Amendment 39-
16066 (74 FR 55755, October 29, 2009), that might appear to conflict 
with the requirements of this proposed AD. However, alternative methods 
of compliance (AMOCs) have already been issued for those ADs to allow 
installation of the MOV actuators that are required for compliance with 
this proposed AD. Those AMOCs preclude any potential conflicts between 
ADs. No new AMOC is needed for this proposed AD regarding this issue.
    AD 2015-21-09, Amendment 39-18302 (80 FR 65121, October 26, 2015) 
(``AD 2015-21-09''), which applies to Model 767 airplanes, was prompted 
by reports of latently failed MOV actuators of the fuel shutoff valves 
discovered during fuel filter replacement. AD 2015-21-09 requires 
revising the maintenance or inspection program to include new AWLs.
    AD 2015-19-04, Amendment 39-18267 (80 FR 55505, September 16, 
2015), which applies to Model 757 airplanes was prompted by reports of

[[Page 13074]]

latently failed MOV actuators of the fuel shutoff valves discovered 
during fuel filter replacement. This AD requires revising the 
maintenance or inspection program to include new AWLs.
    AD 2015-21-10, Amendment 39-18303 (80 FR 65130, October 26, 2015), 
which applies to Model 737-600, -700, -700C, -800, -900, and -900ER 
series airplanes was prompted by reports of latently failed MOV 
actuators of the fuel shutoff valves discovered during fuel filter 
replacement. This AD requires revising the maintenance or inspection 
program to include a new AWL.
    AD 2016-04-20, Amendment 39-18414 (81 FR 10460, March 1, 2016) 
(``AD 2016-04-20''), which applies to Model 737-600, -700, -700C, -800, 
-900, and -900ER series airplanes, Model 757 airplanes, Model 767 
airplanes, and Model 777 airplanes, resulted from fuel system reviews 
conducted by the manufacturer. This AD requires an inspection to 
determine if certain MOV actuators for the fuel tanks or fuel feed 
system are installed on the airplane, and replacement of any affected 
actuators.

Airworthiness Limitations Based on Type Design

    The FAA recently became aware of an issue related to the 
applicability of ADs that require incorporation of the Airworthiness 
Limitations section (ALS) of the Instructions for Continued 
Airworthiness (ICA) into an operator's maintenance or inspection 
program.
    U.S. operators must operate their airplanes in an airworthy 
condition, in accordance with 14 CFR 91.7(a). Included in this 
obligation is the requirement to perform any maintenance or inspections 
specified in the ALS, and in accordance with the ALS as specified in 14 
CFR 43.16 and 91.403(c), unless an alternative has been approved by the 
FAA.
    When a type certificate is issued for a type design, the specific 
ALS, including its revision level, is part of that type design, as 
specified in 14 CFR 21.31(c).
    The sum effect of these operational and maintenance requirements is 
an obligation to comply with the ALS revision defined in the type 
design referenced in the manufacturer's conformity statement. This 
obligation may introduce a conflict with an AD if the AD requires a 
specific ALS revision for new airplanes that are delivered with a later 
ALS revision as part of their type design.
    The FAA has approved AMOCs that allow operators to incorporate the 
most recent ALS revision into their maintenance/inspection programs, in 
lieu of the ALS revision required by the AD. This enables the operator 
to comply with both the AD and the type design.
    However, compliance with AMOCs is normally optional, and we 
recently became aware that some operators choose to retain the AD-
mandated ALS revision in their fleet-wide maintenance/inspection 
programs, including those for new airplanes delivered with later ALS 
revisions, to help standardize the maintenance of the fleet. To ensure 
that operators comply with the applicable ALS revision for newly 
delivered airplanes containing a later revision than that specified in 
an AD, we plan to mandate the latest ALS revision as of the effective 
date of an AD, if we are to mandate a specific ALS revision, and limit 
the applicability of such AD actions to those airplanes to which the 
latest or earlier ALS revisions are applicable as of the effective date 
of that AD.
    This proposed AD therefore mandates the latest ALS revision as of 
the effective date of the AD for Model 737-600, -700, -700C, -800, -
900, and -900ER series airplanes, Model 757 airplanes, and Model 767 
airplanes with an original certificate of airworthiness or original 
export certificate of airworthiness that was issued on or before the 
effective date of this proposed AD. Operators of airplanes with an 
original certificate of airworthiness or original export certificate of 
airworthiness issued after that date must comply with the airworthiness 
limitations specified as part of the approved type design.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between this Proposed AD and the Service 
Information.'' For information on the procedures and compliance times, 
see this service information at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2017-0127.
    This proposed AD also requires revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
Critical Design Configuration Control Limitations (CDCCLs) described in 
the ALS of the ICA. Compliance with these

[[Page 13075]]

actions and CDCCLs is required by 14 CFR 91.403(c). For airplanes that 
have been previously modified, altered, or repaired in the areas 
addressed by this proposed AD, the operator may not be able to 
accomplish the actions described in the revisions. In this situation, 
to comply with 14 CFR 91.403(c), the operator must request approval of 
an AMOC according to paragraph (l) of this proposed AD. The request 
should include a description of changes to the required inspections 
that will ensure the continued operational safety of the airplane.

Costs of Compliance

    We estimate that this proposed AD affects 2,557 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),

(d) Subject

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

(e) Unsafe Condition

    This AD was prompted by reports of latently failed motor 
operated valve (MOV) actuators of the fuel shutoff valves. We are 
issuing this AD to prevent a latent failure of the actuator for the 
engine or auxiliary power unit (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.

(f) Compliance

to determine the part numbers of the MOV actuators of the fuel 
shutoff valves for the left and right engines, in accordance with 
the Accomplishment Instructions of Boeing Service Bulletin 737-28-
1314, dated November 17, 2014. 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.
    (2) For airplanes identified in paragraphs (c)(2) and (c)(3) of 
this AD: Within 8 years after the effective date of this AD, do an 
inspection to determine the part numbers of the MOV actuators of the

using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in paragraph (m)(1) of this AD. 
Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Seattle ACO, to make those findings. To be approved, the 
repair method, modification deviation, or alteration deviation must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs

    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
