ACTION: Final rule. AGENCY: (i) Parts Installation Prohibition [FR Doc. 2016–04033 Filed 2–29–16; 8:45 am] DEPARTMENT OF TRANSPORTATION We are superseding Airworthiness Directive (AD) 2008–26– 07 for all 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. AD 2008–26–07 required repetitive inspections of the lower skin and stringers at certain stations, and corrective actions if necessary. This new AD continues to require the actions specified in AD 2008–26–07 and also requires 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. 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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2008–26–07, Amendment 39–15773 (73 FR 78946, December 24, 2008), (‘‘AD 2008–26– 07’’). AD 2008–26–07 applied 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 airplanes; Model DC–8–60F series airplanes; Model DC–8–70 series airplanes; and Model DC–8–70F series airplanes. The NPRM published in the Federal Register on July 2, 2015 (80 FR 38038) (‘‘the NPRM’’). The NPRM was prompted by certain mandated programs intended to support the airplane reaching its limit of validity of E:\FR\FM\01MRR1.SGM 01MRR1 10466 Federal Register / Vol. 81, No. 40 / Tuesday, March 1, 2016 / Rules and Regulations the engineering data that support the established structural maintenance program. The NPRM proposed to continue to require the actions specified in AD 2008–26–07 and also to 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; and corrective actions if necessary. 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. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA’s response to the comment. Request To Clarify the Actions in Paragraph (j)(1) of the Proposed AD Boeing requested that we clarify paragraph (j)(1) of the proposed AD. Boeing stated that paragraph (j)(1) of the proposed AD does not specify what to inspect or how to inspect. Boeing recommended that a description similar to that of paragraph (j)(2) of the proposed AD be included in paragraph (j)(1) of the proposed AD. We agree with the request to clarify the inspection requirements. Paragraph (j)(l) of the AD is for airplanes that have previous structural repairs at the lower skins, stringers, and splice. For those airplanes, because the details of the configuration are not known, a specific description of the area to be inspected cannot be given. Paragraph (j)(2) of this AD provides specific inspections for certain airplanes because those inspections are described in Boeing Service Bulletin DC8–57–104, dated August 18, 2014. However, that service information does not provide specific inspection areas for airplanes identified in paragraph (j)(1) of this AD. Therefore, for the inspection and applicable corrective actions, paragraph (j)(1) of this AD requires that the operator use a method approved in the accordance with the procedures specified in paragraph (m) of this AD. We have revised paragraph (j)(1) of this AD to specify the general inspection area, which includes the lower skins, stringers, and splice fittings. Clarification of Actions Specified in Paragraph (k) of This AD. Paragraph (k) of the NPRM referred to Boeing Service Bulletin DC8–57–104, dated August 18, 2014, for the compliance times for the actions required by that paragraph but did not include a reference for the installation and inspections required by paragraph (k) of this AD. We have revised paragraph (k) of this AD to refer to Boeing Service Bulletin DC8–57–104, dated August 18, 2014, as the appropriate source of service information for accomplishing the installation and inspections. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD 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 NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. 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. Costs of Compliance We estimate that this AD affects 12 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Inspection [retained actions from AD 2008-26-07, Amendment 39–15773 (73 FR 78946, December 24, 2008)].

Federal Register / Vol. 81, No. 40 / Tuesday, March 1, 2016 / Rules and Regulations 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 AD. ■ Authority for this Rulemaking § 39.13 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 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. asabaliauskas on DSK5VPTVN1PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2008-26-07 for 
all 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. AD 2008-26-07 required 
repetitive inspections of the lower skin and stringers at certain 
stations, and corrective actions if necessary. This new AD continues to 
require the actions specified in AD 2008-26-07 and also requires 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. 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.

DATES: This AD is effective April 5, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 5, 
2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
January 28, 2009 (73 FR 78946, December 24, 2008).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2008-26-07, Amendment 39-15773 (73 FR 78946, 
December 24, 2008), (``AD 2008-26-07''). AD 2008-26-07 applied 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 
airplanes; Model DC-8-60F series airplanes; Model DC-8-70 series 
airplanes; and Model DC-8-70F series airplanes. The NPRM published in 
the Federal Register on July 2, 2015 (80 FR 38038) (``the NPRM''). The 
NPRM was prompted by certain mandated programs intended to support the 
airplane reaching its limit of validity of

[[Page 10466]]

the engineering data that support the established structural 
maintenance program. The NPRM proposed to continue to require the 
actions specified in AD 2008-26-07 and also to 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; and corrective actions 
if necessary. 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to the comment.

Request To Clarify the Actions in Paragraph (j)(1) of the Proposed AD

    Boeing requested that we clarify paragraph (j)(1) of the proposed 
AD. Boeing stated that paragraph (j)(1) of the proposed AD does not 
specify what to inspect or how to inspect. Boeing recommended that a 
description similar to that of paragraph (j)(2) of the proposed AD be 
included in paragraph (j)(1) of the proposed AD.
    We agree with the request to clarify the inspection requirements. 
Paragraph (j)(l) of the AD is for airplanes that have previous 
structural repairs at the lower skins, stringers, and splice. For those 
airplanes, because the details of the configuration are not known, a 
specific description of the area to be inspected cannot be given. 
Paragraph (j)(2) of this AD provides specific inspections for certain 
airplanes because those inspections are described in Boeing Service 
Bulletin DC8-57-104, dated August 18, 2014. However, that service 
information does not provide specific inspection areas for airplanes 
identified in paragraph (j)(1) of this AD. Therefore, for the 
inspection and applicable corrective actions, paragraph (j)(1) of this 
AD requires that the operator use a method approved in the accordance 
with the procedures specified in paragraph (m) of this AD. We have 
revised paragraph (j)(1) of this AD to specify the general inspection 
area, which includes the lower skins, stringers, and splice fittings.

Clarification of Actions Specified in Paragraph (k) of This AD.

    Paragraph (k) of the NPRM referred to Boeing Service Bulletin DC8-
57-104, dated August 18, 2014, for the compliance times for the actions 
required by that paragraph but did not include a reference for the 
installation and inspections required by paragraph (k) of this AD. We 
have revised paragraph (k) of this AD to refer to Boeing Service 
Bulletin DC8-57-104, dated August 18, 2014, as the appropriate source 
of service information for accomplishing the installation and 
inspections.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD 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 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

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.

Costs of Compliance

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

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                              Cost per          Cost on U.S.

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

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

                                               On-Condition Costs

Repetitive ETLF inspection..............  8 work-hour x $85 per hour              $0  $680 per inspection cycle.
                                           = $680 per inspection
                                           cycle.
----------------------------------------------------------------------------------------------------------------


[[Page 10467]]

    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 
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 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.

2008), with no changes. 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 With No Changes

    This paragraph restates the exception specified in paragraph (h) 
of AD 2008-26-07, Amendment 39-15773 (73 FR 78946, December 24, 
2008), with no changes. 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.

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) 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) of this AD 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.
