ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787–8 SUMMARY: E:\FR\FM\17NOP1.SGM 17NOP1 Federal Register / Vol. 79, No. 221 / Monday, November 17, 2014 / Proposed Rules airplanes. This proposed AD was prompted by reports of a potential latent failure of the valve actuator circuitry, which was not identified during actuator development. This proposed AD would require replacing certain engine and auxiliary power unit (APU) fuel shutoff valve actuators with new actuators, and would also require revising the maintenance or inspection program to include a new airworthiness limitation into the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA). We are proposing this AD to prevent latent failures of the fuel shutoff valve actuators, which could result in the inability to shut off fuel to the engine or APU in the case of an engine or APU fire. If the fuel cannot be shut off to a fire, the engine or APU fire could be uncontrollable, which could lead to structural failure. DATES: We must receive comments on this proposed AD by January 2, 2015. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

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– 2014–0773; Directorate Identifier 2014– NM–068–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 http:// 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 received reports on Model 787 airplanes of a potential latent failure of the valve actuator circuitry, which was not identified during actuator development. The fuel shutoff valve actuator circuit design provides common input power through microswitches to both the motor and position indications. The latent failure condition has the potential for a stuck microswitch, which could lead to a disagreement between the valve command and position indication. If a command is sent to change the valve position and one of the internal microswitches is stuck in the depressed state, power would immediately provide indication that the valve transitioned to its commanded state, when the motor actually never received power to rotate. This condition, if not corrected, could result in the inability to shut off fuel to the engine or APU in the case of an engine or APU fire. If the fuel cannot be shut off to a fire, the engine or APU fire could be uncontrollable, which could lead to structural failure. PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 68385 Relevant Service Information We reviewed Boeing Service Bulletin B787–81205–SB280015–00, Issue 002, dated June 19, 2014. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for Docket No. FAA–2014–0773. 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 the same type design. Proposed AD Requirements This proposed AD would require airplanes with certain part number shutoff valves to revise the maintenance or inspection program to add airworthiness limitation number 28– AWL–ACT, ‘‘Engine and APU Shut-Off Valve Actuator Test.’’ This proposed AD would also require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Difference Between this Proposed AD and the Service Information.’’ This proposed AD would require revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, an operator might not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) in accordance with the provisions of paragraph (k) 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. Explanation of ‘‘RC’’ Steps in Service Information The FAA worked in conjunction with industry, under the Airworthiness Directives Implementation Aviation Rulemaking Committee, to enhance the AD system. One enhancement was a new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner’s/ operator’s understanding of crucial AD E:\FR\FM\17NOP1.SGM 17NOP1 68386 Federal Register / Vol. 79, No. 221 / Monday, November 17, 2014 / Proposed Rules requirements and help provide consistent judgment in AD compliance. The actions specified in the service information described previously include steps that are labeled as RC (required for compliance) because these steps have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. As noted in the specified service information, steps labeled as RC and all subordinate steps must be done to comply with the proposed AD. However, steps that are not labeled as RC are recommended. Those steps that are not labeled as RC may be deviated from, done as part of other actions, or done using accepted methods different from those identified in the service information without obtaining approval of an AMOC, provided the steps labeled as RC can be done and the airplane can be put back in a serviceable condition. Any substitutions or changes to steps labeled as RC will require approval of an alternative method of compliance. Differences Between This Proposed AD and the Service Information Although Boeing Service Bulletin B787–81205–SB280015–00, Issue 002, dated June 19, 2014, describes installing engine fuel shutoff valve and APU fuel shutoff valve actuators having part number (P/N) 53–0037, this proposed AD would prohibit installing valves having P/N 53–0037, and require installing certain other valves. We have coordinated this difference with Boeing. The applicability of this proposed AD includes all Model 787–8 airplanes, which differs from the effectivity of the service information referenced previously. The parts are rotable, therefore, this proposed AD includes all Model 787–8 airplanes. Costs of Compliance We estimate that this proposed AD affects 6 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Maintenance program revision ....................... Engine and APU fuel shutoff valve actuator replacement. 1 work-hour × $85 per hour = $85 ................. 10 work-hours × $85 per hour = $850 ........... According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. mstockstill on DSK4VPTVN1PROD 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 VerDate Sep<11>2014 16:18 Nov 14, 2014 Jkt 235001 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 (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701.

(c) Applicability This AD applies to all The Boeing Company Model 787–8 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 28, Fuel. (e) Unsafe Condition This AD was prompted by a report of an error in the valve actuator design. We are issuing this AD to prevent latent failures of the fuel shutoff valve actuators, which could result in the inability to shut off fuel to the engine or APU in the case of an engine or APU fire. If the fuel cannot be shut off to a fire the engine or APU fire could be uncontrollable which could lead to structural failure. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Maintenance or Inspection Program Revision Within 30 days after the effective date of this AD, revise the maintenance or inspection E:\FR\FM\17NOP1.SGM 17NOP1 Federal Register / Vol. 79, No. 221 / Monday, November 17, 2014 / Proposed Rules program, as applicable, to add airworthiness limitation number 28–AWL–ACT, by incorporating the information specified in figure 1 to paragraph (g) of this AD into the Airworthiness Limitations Section of the Instructions for Continued Airworthiness. This may be accomplished by inserting a copy of airworthiness limitation number 28– AWL–ACT into the maintenance or inspection program, as applicable. For the airplanes identified in the applicability note of airworthiness limitation number 28–AWL– ACT, the initial compliance time for accomplishing the actions specified in figure 1 to paragraph (g) of this AD is within 10 days after accomplishment of the 68387 maintenance or inspection program revision required by this paragraph. When the engine and APU fuel shutoff valve actuators have been replaced as required by paragraph (i) of this AD, the airworthiness limitation number 28–AWL–ACT required by this paragraph may be removed from the maintenance or inspection program, as applicable.

AD 2006–22–15 currently requires repetitive inspections for cracking of certain panel webs and stiffeners of the nose wheel well (NWW), and corrective actions if necessary. AD 2006–22–15 also requires replacing certain panels with new panels, which terminates the repetitive inspections. Since we issued AD 2006–22–15, we received reports of fatigue cracking in the panel webs and stiffeners of the NWW prior to the inspection threshold of AD 2006–22–15. This proposed AD would reduce a compliance time and add certain inspections and repair if necessary. We are proposing this AD to prevent fatigue cracking of the NWW side and top panels, which could result in a NWW depressurization event severe enough to reduce the structural integrity of the fuselage. SUMMARY: We must receive comments on this proposed AD by January 2, 2015.

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 787-8

[[Page 68385]]

airplanes. This proposed AD was prompted by reports of a potential 
latent failure of the valve actuator circuitry, which was not 
identified during actuator development. This proposed AD would require 
replacing certain engine and auxiliary power unit (APU) fuel shutoff 
valve actuators with new actuators, and would also require revising the 
maintenance or inspection program to include a new airworthiness 
limitation into the Airworthiness Limitations Section (ALS) of the 
Instructions for Continued Airworthiness (ICA). We are proposing this 
AD to prevent latent failures of the fuel shutoff valve actuators, 
which could result in the inability to shut off fuel to the engine or 
APU in the case of an engine or APU fire. If the fuel cannot be shut 
off to a fire, the engine or APU fire could be uncontrollable, which 
could lead to structural failure.

DATES: We must receive comments on this proposed AD by January 2, 2015.

Discussion

    We received reports on Model 787 airplanes of a potential latent 
failure of the valve actuator circuitry, which was not identified 
during actuator development. The fuel shutoff valve actuator circuit 
design provides common input power through micro-switches to both the 
motor and position indications. The latent failure condition has the 
potential for a stuck micro-switch, which could lead to a disagreement 
between the valve command and position indication. If a command is sent 
to change the valve position and one of the internal micro-switches is 
stuck in the depressed state, power would immediately provide 
indication that the valve transitioned to its commanded state, when the 
motor actually never received power to rotate. This condition, if not 
corrected, could result in the inability to shut off fuel to the engine 
or APU in the case of an engine or APU fire. If the fuel cannot be shut 
off to a fire, the engine or APU fire could be uncontrollable, which 
could lead to structural failure.

Relevant Service Information

    We reviewed Boeing Service Bulletin B787-81205-SB280015-00, Issue 
002, dated June 19, 2014. For information on the procedures and 
compliance times, see this service information at http://www.regulations.gov by searching for Docket No. FAA-2014-0773.

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 the same type design.

Proposed AD Requirements

    This proposed AD would require airplanes with certain part number 
shutoff valves to revise the maintenance or inspection program to add 
airworthiness limitation number 28-AWL-ACT, ``Engine and APU Shut-Off 
Valve Actuator Test.'' This proposed AD would also require 
accomplishing the actions specified in the service information 
described previously, except as discussed under ``Difference Between 
this Proposed AD and the Service Information.''
    This proposed AD would require revisions to certain operator 
maintenance documents to include new inspections. Compliance with these 
inspections is required by section 91.403(c) of the Federal Aviation 
Regulations (14 CFR 91.403(c)). For airplanes that have been previously 
modified, altered, or repaired in the areas addressed by these 
inspections, an operator might not be able to accomplish the 
inspections described in the revisions. In this situation, to comply 
with 14 CFR 91.403(c), the operator must request approval of an 
alternative method of compliance (AMOC) in accordance with the 
provisions of paragraph (k) 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.

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directives Implementation Aviation Rulemaking Committee, 
to enhance the AD system. One enhancement was a new process for 
annotating which steps in the service information are required for 
compliance with an AD. Differentiating these steps from other tasks in 
the service information is expected to improve an owner's/operator's 
understanding of crucial AD

[[Page 68386]]

requirements and help provide consistent judgment in AD compliance. The 
actions specified in the service information described previously 
include steps that are labeled as RC (required for compliance) because 
these steps have a direct effect on detecting, preventing, resolving, 
or eliminating an identified unsafe condition.
    As noted in the specified service information, steps labeled as RC 
and all subordinate steps must be done to comply with the proposed AD. 
However, steps that are not labeled as RC are recommended. Those steps 
that are not labeled as RC may be deviated from, done as part of other 
actions, or done using accepted methods different from those identified 
in the service information without obtaining approval of an AMOC, 
provided the steps labeled as RC can be done and the airplane can be 
put back in a serviceable condition. Any substitutions or changes to 
steps labeled as RC will require approval of an alternative method of 
compliance.

Differences Between This Proposed AD and the Service Information

    Although Boeing Service Bulletin B787-81205-SB280015-00, Issue 002, 
dated June 19, 2014, describes installing engine fuel shutoff valve and 
APU fuel shutoff valve actuators having part number (P/N) 53-0037, this 
proposed AD would prohibit installing valves having P/N 53-0037, and 
require installing certain other valves. We have coordinated this 
difference with Boeing.
    The applicability of this proposed AD includes all Model 787-8 
airplanes, which differs from the effectivity of the service 
information referenced previously. The parts are rotable, therefore, 
this proposed AD includes all Model 787-8 airplanes.

Costs of Compliance

    We estimate that this proposed AD affects 6 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators

Maintenance program revision..........  1 work-hour x $85 per                 $0             $85            $510
                                         hour = $85.
Engine and APU fuel shutoff valve       10 work-hours x $85 per                0             850           5,100
 actuator replacement.                   hour = $850.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

2. Amend Sec.  39.13 by adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2014-0773; Directorate Identifier 
2014-NM-068-AD.

(a) Comments Due Date

    We must receive comments by January 2, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 787-8 airplanes, 
certificated in any category.

(d) Subject

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

(e) Unsafe Condition

    This AD was prompted by a report of an error in the valve 
actuator design. We are issuing this AD to prevent latent failures 
of the fuel shutoff valve actuators, which could result in the 
inability to shut off fuel to the engine or APU in the case of an 
engine or APU fire. If the fuel cannot be shut off to a fire the 
engine or APU fire could be uncontrollable which could lead to 
structural failure.

(f) Compliance

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

(g) Maintenance or Inspection Program Revision

    Within 30 days after the effective date of this AD, revise the 
maintenance or inspection

[[Page 68387]]

program, as applicable, to add airworthiness limitation number 28-
AWL-ACT, by incorporating the information specified in figure 1 to 
paragraph (g) of this AD into the Airworthiness Limitations Section 
of the Instructions for Continued Airworthiness. This may be 
accomplished by inserting a copy of airworthiness limitation number 
28-AWL-ACT into the maintenance or inspection program, as 
applicable. For the airplanes identified in the applicability note 
of airworthiness limitation number 28-AWL-ACT, the initial 
compliance time for accomplishing the actions specified in figure 1 
to paragraph (g) of this AD is within 10 days after accomplishment 
of the maintenance or inspection program revision required by this 
paragraph. When the engine and APU fuel shutoff valve actuators have 
been replaced as required by paragraph (i) of this AD, the 
airworthiness limitation number 28-AWL-ACT required by this 
paragraph may be removed from the maintenance or inspection program, 
as applicable.
