ACTION: Notice of proposed rulemaking (NPRM). asabaliauskas on DSK5VPTVN1PROD with PROPOSALS AGENCY: We propose to supersede Airworthiness Directive (AD) 2008–26– 07, which applies to all McDonnell Douglas Model DC–8–11, DC–8–12, DC– 8–21, DC–8–31, DC–8–32, DC–8–33, DC–8–41, DC–8–42, and DC–8–43 airplanes; Model DC–8–50 series airplanes; Model DC–8F–54 and DC– 8F–55 airplanes; Model DC–8–60 series SUMMARY: VerDate Sep<11>2014 21:02 Jul 01, 2015 Jkt 235001 airplanes; Model DC–8–60F series airplanes; Model DC–8–70 series airplanes; and Model DC–8–70F series airplanes. AD 2008–26–07 currently requires repetitive inspections of the lower skin and stringers at certain stations, and corrective actions if necessary. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would also require an eddy current high frequency (ETHF) inspection for cracks of the fastener open holes common to the lower skins, stringers, and splice fittings at a certain station; installation of external doublers and fasteners and repetitive eddy current low frequency (ETLF) inspections around the fasteners for any crack; and corrective actions if necessary. We are proposing this AD to detect and correct cracks in the lower skins, stringers, and fastener holes of the splice fittings, which could result in the loss of structural integrity of the airplane.

Discussion On December 12, 2008, we issued AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008), for all McDonnell Douglas Model DC–8–11, DC–8–12, DC–8–21, DC–8–31, DC–8–32, DC–8–33, DC–8–41, DC–8–42, and DC– 8–43 airplanes; Model DC–8–50 series airplanes; Model DC–8F–54 and DC– 8F–55 airplanes; Model DC–8–60 series airplanes; Model DC–8–60F series airplanes; Model DC–8–70 series airplanes; and Model DC–8–70F series airplanes. AD 2008–26–07 requires repetitive inspections of the lower skin and stringers at stations Xw=408 and Xw=-408, and corrective actions if E:\FR\FM\02JYP1.SGM 02JYP1 38039 Federal Register / Vol. 80, No. 127 / Thursday, July 2, 2015 / Proposed Rules necessary. AD 2008–26–07 resulted from reports of cracks in the skins and stringers at the end fasteners common to the stringer end fittings at stations Xw=408 and Xw=-408 wing splice joints. We issued AD 2008–26–07 to detect and correct fatigue cracking in the skins and stringers at the end fasteners common to the stringer end fittings at certain station and wing splice joints, which could result in wing structure that might not sustain limit load, and consequent loss of structural integrity of the wing. asabaliauskas on DSK5VPTVN1PROD with PROPOSALS Widespread Fatigue Damage As described in FAA Advisory Circular 120–104 (http://www.faa.gov/ documentLibrary/media/Advisory_ Circular/120-104.pdf), several programs have been developed to support initiatives that will ensure the continued airworthiness of aging airplane structure. The last element of those initiatives is the requirement to establish a limit of validity (LOV) of the engineering data that support the structural maintenance program under 14 CFR 26.21. This proposed AD is the result of an assessment of the previously established programs by Boeing during the process of establishing the LOV for The Boeing Company Model DC–8–11, DC–8–12, DC–8–21, DC–8–31, DC–8–32, DC–8–33, DC–8–41, DC–8–42, and DC– 8–43 airplanes; Model DC–8–50 series airplanes; Model DC–8F–54 and DC– 8F–55 airplanes; Model DC–8–60 series airplanes; Model DC–8–60F series airplanes; Model DC–8–70 series airplanes; and Model DC–8–70F series airplanes. The actions specified in this proposed AD are necessary to complete certain programs to ensure the continued airworthiness of aging airplane structure and to support an airplane reaching its LOV. We are proposing this AD to detect and correct cracks in the lower skins, stringers, and fastener holes of the splice fittings, which could result in the loss of structural integrity of the airplane. Actions Since AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008) Was Issued Since we issued AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008), we have received new service information to ensure the continued airworthiness of aging airplane structure and to support an airplane reaching its LOV. The new VerDate Sep<11>2014 21:02 Jul 01, 2015 Jkt 235001 inspection and modification of the left and right lower wing skin, stringers, and splice fittings will support operation up to the DC–8 LOV. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Service Bulletin DC8–57–104, dated August 18, 2014. The service information describes procedures for certain airplanes for an ETHF inspection for cracks of the fastener open holes common to the lower skins, stringers, and splice fittings at a certain station; installation of external doublers and fasteners and repetitive ETLF inspections around the fasteners for any crack; and corrective actions. 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 of this NPRM. 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 retain all requirements of AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008). This proposed AD would also require an ETHF inspection for cracks of the fastener open holes common to the lower skins, stringers, and splice fittings at a certain station; installation of external doublers and fasteners and repetitive ETLF inspections around the fasteners for any crack if necessary; and corrective actions. Clarification of Actions for Groups 1–3, Configuration 1 Airplanes Where the Accomplishment Instructions of Boeing Service Bulletin DC8–57–104, dated August 18, 2014, specifies repair, this AD also requires an inspection and possible other actions. Change to AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008) Since AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008), was issued, the AD format has been revised, and certain paragraphs have been rearranged with new title PO 00000 Frm 00021 Fmt 4702 Sfmt 4702 headers. As a result, the corresponding paragraph identifiers have been redesignated in this proposed AD, as listed in the following table: REVISED PARAGRAPH IDENTIFIERS Requirement in AD 2008–26–07 paragraph paragraph paragraph paragraph (e) ............ (f) ............. (g) ............ (h) ............ Corresponding requirement in this proposed AD paragraph paragraph paragraph paragraph (f) (g) (h) (i) Explanation of ‘‘RC’’ Steps in Service Information The FAA worked in conjunction with industry, under the Airworthiness Directive Implementation Aviation Rulemaking Committee (ARC), 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 requirements and help provide consistent judgment in AD compliance. The steps identified as RC (required for compliance) in any service information identified previously have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. For service information that contains steps that are labeled as Required for Compliance (RC), the following provisions apply: (1) 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, and an AMOC is required for any deviations to RC steps, including substeps and identified figures; and (2) 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. Costs of Compliance We estimate that this proposed AD affects 12 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\02JYP1.SGM 02JYP1 38040 Federal Register / Vol. 80, No. 127 / Thursday, July 2, 2015 / Proposed Rules ESTIMATED COSTS Cost per product Parts cost Action Labor cost Inspection [retained actions from AD 2008-26-07, Amendment 39–15773 (73 FR 78946, December 24, 2008)]. ETHF Inspection [new proposed action] ............. 6 work-hours × $85 per hour = $510 per inspection cycle. $0 $510 $6,120 per inspection cycle 8 work-hours × $85 per hour = $680 per inspection cycle. $0 $680 $8,160 per inspection cycle We estimate the following costs to do any necessary certain follow-on actions that would be required based on the results of the proposed inspection. We Cost on U.S. operators have no way of determining the number of aircraft that might need these actions: ON-CONDITION COSTS Action Labor cost Installation of External Doubler .............................. Repetitive ETLF inspection .................................... 5 work-hour × $85 per hour = $425 ....................... 8 work-hour × $85 per hour = $680 per inspection cycle. For all actions and repairs on Groups 1–3, Configuration 1 Airplanes, we have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. asabaliauskas on DSK5VPTVN1PROD 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 have 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 that the proposed regulation: VerDate Sep<11>2014 21:02 Jul 01, 2015 Jkt 235001 Parts cost $20,000 $0 Cost per product $20,425 $680 per inspection cycle (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. (b) Affected ADs This AD replaces AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008). List of Subjects in 14 CFR Part 39 (d) Subject Joint Aircraft System Component (JASC) 57, Wings. 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. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008), and adding the following new AD: ■ The Boeing Company: Docket No. FAA– 2015–2455; Directorate Identifier 2014– NM–180–AD.

ACTION: Notice of proposed rulemaking. AGENCY: The Danny Keysar Child Product Safety Notification Act, section 104 of the Consumer Product Safety Improvement Act of 2008 (‘‘CPSIA’’), requires the United States Consumer Product Safety Commission (‘‘Commission’’ or ‘‘CPSC’’) to promulgate consumer product safety standards for durable infant or toddler products. These standards are to be ‘‘substantially the same as’’ applicable voluntary standards or more stringent than the voluntary standard if the Commission concludes that more stringent requirements would further reduce the risk of injury associated with the product. The Commission is proposing a safety standard for portable hook-on chairs (‘‘hook-on chairs’’) in response to the direction under section 104(b) of the CPSIA. In addition, the Commission is proposing an amendment to include an additional CFR part in the list of notice of requirements (‘‘NORs’’) issued by the Commission.

airplanes; Model DC-8-60 series airplanes; Model DC-8-60F series 
airplanes; Model DC-8-70 series airplanes; and Model DC-8-70F series 
airplanes. AD 2008-26-07 currently requires repetitive inspections of 
the lower skin and stringers at certain stations, and corrective 
actions if necessary. This proposed AD is intended to complete certain 
mandated programs intended to support the airplane reaching its limit 
of validity (LOV) of the engineering data that support the established 
structural maintenance program. This proposed AD would also require an 
eddy current high frequency (ETHF) inspection for cracks of the 
fastener open holes common to the lower skins, stringers, and splice 
fittings at a certain station; installation of external doublers and 
fasteners and repetitive eddy current low frequency (ETLF) inspections 
around the fasteners for any crack; and corrective actions if 
necessary. We are proposing this AD to detect and correct cracks in the 
lower skins, stringers, and fastener holes of the splice fittings, 
which could result in the loss of structural integrity of the airplane.

Discussion

    On December 12, 2008, we issued AD 2008-26-07, Amendment 39-15773 
(73 FR 78946, December 24, 2008), for all McDonnell Douglas Model DC-8-
11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and 
DC-8-43 airplanes; Model DC-8-50 series airplanes; Model DC-8F-54 and 
DC-8F-55 airplanes; Model DC-8-60 series airplanes; Model DC-8-60F 
series airplanes; Model DC-8-70 series airplanes; and Model DC-8-70F 
series airplanes. AD 2008-26-07 requires repetitive inspections of the 
lower skin and stringers at stations Xw=408 and Xw=-408, and corrective 
actions if

[[Page 38039]]

necessary. AD 2008-26-07 resulted from reports of cracks in the skins 
and stringers at the end fasteners common to the stringer end fittings 
at stations Xw=408 and Xw=-408 wing splice joints. We issued AD 2008-
26-07 to detect and correct fatigue cracking in the skins and stringers 
at the end fasteners common to the stringer end fittings at certain 
station and wing splice joints, which could result in wing structure 
that might not sustain limit load, and consequent loss of structural 
integrity of the wing.

Widespread Fatigue Damage

    As described in FAA Advisory Circular 120-104 (http://www.faa.gov/documentLibrary/media/Advisory_Circular/120-104.pdf), several programs 
have been developed to support initiatives that will ensure the 
continued airworthiness of aging airplane structure. The last element 
of those initiatives is the requirement to establish a limit of 
validity (LOV) of the engineering data that support the structural 
maintenance program under 14 CFR 26.21. This proposed AD is the result 
of an assessment of the previously established programs by Boeing 
during the process of establishing the LOV for The Boeing Company Model 
DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, 
and DC-8-43 airplanes; Model DC-8-50 series airplanes; Model DC-8F-54 
and DC-8F-55 airplanes; Model DC-8-60 series airplanes; Model DC-8-60F 
series airplanes; Model DC-8-70 series airplanes; and Model DC-8-70F 
series airplanes. The actions specified in this proposed AD are 
necessary to complete certain programs to ensure the continued 
airworthiness of aging airplane structure and to support an airplane 
reaching its LOV.
    We are proposing this AD to detect and correct cracks in the lower 
skins, stringers, and fastener holes of the splice fittings, which 
could result in the loss of structural integrity of the airplane.

Actions Since AD 2008-26-07, Amendment 39-15773 (73 FR 78946, December 
24, 2008) Was Issued

    Since we issued AD 2008-26-07, Amendment 39-15773 (73 FR 78946, 
December 24, 2008), we have received new service information to ensure 
the continued airworthiness of aging airplane structure and to support 
an airplane reaching its LOV. The new inspection and modification of 
the left and right lower wing skin, stringers, and splice fittings will 
support operation up to the DC-8 LOV.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin DC8-57-104, dated August 18, 
2014. The service information describes procedures for certain 
airplanes for an ETHF inspection for cracks of the fastener open holes 
common to the lower skins, stringers, and splice fittings at a certain 
station; installation of external doublers and fasteners and repetitive 
ETLF inspections around the fasteners for any crack; and corrective 
actions. 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 of this 
NPRM.

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 retain all requirements of AD 2008-26-07, 
Amendment 39-15773 (73 FR 78946, December 24, 2008). This proposed AD 
would also require an ETHF inspection for cracks of the fastener open 
holes common to the lower skins, stringers, and splice fittings at a 
certain station; installation of external doublers and fasteners and 
repetitive ETLF inspections around the fasteners for any crack if 
necessary; and corrective actions.

Clarification of Actions for Groups 1-3, Configuration 1 Airplanes

    Where the Accomplishment Instructions of Boeing Service Bulletin 
DC8-57-104, dated August 18, 2014, specifies repair, this AD also 
requires an inspection and possible other actions.

Change to AD 2008-26-07, Amendment 39-15773 (73 FR 78946, December 24, 
2008)

    Since AD 2008-26-07, Amendment 39-15773 (73 FR 78946, December 24, 
2008), was issued, the AD format has been revised, and certain 
paragraphs have been rearranged with new title headers. As a result, 
the corresponding paragraph identifiers have been redesignated in this 
proposed AD, as listed in the following table:

                      Revised Paragraph Identifiers

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

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive Implementation Aviation Rulemaking Committee 
(ARC), 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 requirements and help provide consistent 
judgment in AD compliance. The steps identified as RC (required for 
compliance) in any service information identified previously have a 
direct effect on detecting, preventing, resolving, or eliminating an 
identified unsafe condition.
    For service information that contains steps that are labeled as 
Required for Compliance (RC), the following provisions apply: (1) 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, 
and an AMOC is required for any deviations to RC steps, including 
substeps and identified figures; and (2) 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.

Costs of Compliance

    We estimate that this proposed AD affects 12 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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

    We estimate the following costs to do any necessary certain follow-
on actions that would be required based on the results of the proposed 
inspection. We have no way of determining the number of aircraft that 
might need these actions:

                                            cycle.
----------------------------------------------------------------------------------------------------------------

    For all actions and repairs on Groups 1-3, Configuration 1 
Airplanes, we have received no definitive data that would enable us to 
provide cost estimates for the on-condition actions specified in 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 have 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 that the 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

(d) Subject

    Joint Aircraft System Component (JASC) 57, Wings.

(e) Unsafe Condition

    This AD was prompted by certain mandated programs intended to 
support the airplane reaching its limit of validity of the 
engineering data that support the established structural maintenance 
program. We are issuing this AD to detect and correct cracks in the 
lower skins, stringers, and fastener holes of the splice fittings, 
which could result in the loss of structural integrity of the 
airplane.

(f) Compliance

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

(g) Retained Repetitive Inspections

    This paragraph restates the requirements of paragraph (f) of AD 
2008-26-07, Amendment 39-15773 (73 FR 78946, December 24, 2008). At 
the times specified in paragraph 1.E., ``Compliance,'' of Boeing 
Alert Service Bulletin DC8-57A102, dated February 12, 2008, except 
as provided by paragraph (h) of this AD, do the applicable 
inspections for fatigue cracking of the lower skin and stringers at 
stations Xw=408 and Xw=-408, and do all applicable corrective 
actions, by accomplishing all applicable actions

[[Page 38041]]

specified in the Accomplishment Instructions of Boeing Alert Service 
Bulletin DC8-57A102, dated February 12, 2008. Do all corrective 
actions before further flight. Thereafter, repeat the inspections at 
the applicable intervals specified in paragraph 1.E., 
``Compliance,'' of Boeing Alert Service Bulletin DC8-57A102, dated 
February 12, 2008, until paragraph (j) of this AD is done.

(h) Retained Exception for Compliance Time

    This paragraph restates the exception specified in paragraph (g) 
of AD 2008-26-07, Amendment 39-15773 (73 FR 78946, December 24, 
2008). Where Boeing Alert Service Bulletin DC8-57A102, dated 
February 12, 2008, specifies a compliance time ``after the date on 
this service bulletin,'' this AD requires compliance within the 
specified compliance time after January 28, 2009 (the effective date 
of AD 2008-26-07).

(i) Retained Exception for Corrective Action

    This paragraph restates the exception specified in paragraph (h) 
of AD 2008-26-07, Amendment 39-15773 (73 FR 78946, December 24, 
2008): If any cracking is found during any inspection required by 
paragraph (g) of this AD, and Boeing Alert Service Bulletin DC8-
57A102, dated February 12, 2008, specifies to contact Boeing for 
appropriate action: Before further flight, repair the cracking using 
a method approved in accordance with the procedures specified in 
paragraph (m) of this AD.

(j) New Inspections and Corrective Action

    (1) For Groups 1-3, Configuration 1 Airplanes: At the applicable 
time specified in paragraph 1.E., ``Compliance,'' of Boeing Service 
Bulletin DC8-57-104, dated August 18, 2014, except as required in 
paragraph (l) of this AD, do an inspection for any cracking, and do 
all applicable corrective actions using a method approved in 
accordance with the procedures specified in paragraph (m) of this 
AD.
    (2) For Groups 1-3, Configuration 2 Airplanes: At the applicable 
time specified in paragraph 1.E., ``Compliance,'' of Boeing Service 
Bulletin DC8-57-104, dated August 18, 2014, except as required in 
paragraph (l) of this AD, do an eddy current high frequency (ETHF) 
inspection for any cracking of the fastener open holes common to the 
lower skins, stringers, and splice fittings at station Xw=408 and 
Xw=-408 from stringer 51 to stringer 65, in accordance with the 
Accomplishment Instructions of Boeing Service Bulletin DC8-57-104, 
dated August 18, 2014. If any cracking is found, before further 
flight, repair the crack using a method approved in accordance with 
the procedures specified in paragraph (m) of this AD.

(k) New Doubler and Fastener Installation and Eddy Current Low 
Frequency (ETLF) Inspection of the External Doubler and Corrective 
Action

    If no crack is found during the inspection required by paragraph 
(j)(2) of this AD: At the applicable times specified in paragraph 
1.E., ``Compliance,'' of Boeing Service Bulletin DC8-57-104, dated 
August 18, 2014, install external doublers and fasteners, and do an 
external doubler ETLF inspection around the fasteners for any 
cracking. Repeat the external ETLF inspection at the applicable 
intervals specified in 1.E., ``Compliance,'' of Boeing Service 
Bulletin DC8-57-104, dated August 18, 2014. If any cracking is found 
during any ETLF inspection required by this paragraph, before 
further flight, repair the crack using a method approved in 
accordance with the procedures specified in paragraph (m) of this 
AD.

(l) Exception to the Compliance Time

    Where Boeing Service Bulletin DC8-57-104, dated August 18, 2014, 
specifies a compliance time ``after the original issue date of this 
service bulletin,'' this AD requires compliance within the specified 
compliance time after the effective date of this AD.

(m) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles Aircraft Certification Office 
(ACO), FAA, has the authority to approve AMOCs for this AD, if 
requested 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 (n)(1) of this AD. 
Information may be emailed to 9-ANM-LAACO-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 required by this AD if it is approved by the 
Boeing Commercial Airplanes Organization Designation Authorization 
(ODA) that has been authorized by the Manager, Los Angeles ACO, to 
make those findings. For a repair method to be approved, the repair 
must meet the certification basis of the airplane, and the approval 
must specifically refer to this AD.
    (4) AMOCs approved for AD 2008-26-07, Amendment 39-15773 (73 FR 
78946, December 24, 2008), are approved as AMOCs for the 
corresponding provisions of this AD.
    (5) Except as required by paragraphs (j) and (k) of this AD: For 
service information that contains steps that are labeled as Required 
for Compliance (RC), the provisions of paragraphs (m)(5)(i) and 
(m)(5)(ii) apply.
    (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. 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.
