ACTION: Final rule; request for comments. AGENCY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model DC–9–81 (MD– 81), DC–9–82 (MD–82), DC–9–83 (MD– 83), and DC–9–87 (MD–87) airplanes, and Model MD–88 airplanes. This AD requires repetitive eddy current high frequency (ETHF) inspections for any cracking in the left and right side center wing lower skin, and corrective actions if necessary. This AD was prompted by reports of cracking at certain stringers, associated end fittings, and skins in the center wing fuel tank where the stringers meet the end fittings. We are issuing this AD to detect and correct cracking in the center wing lower skin. Such cracking could cause structural failure of the wings. DATES: This AD is effective April 26, 2016.

SUPPLEMENTARY INFORMATION: Discussion We have received reports of cracks at stringers S–15, S–16, or S–17, associated end fittings, and skins in the center wing fuel tank where the stringers meet the end fittings near Xcw=13 and Xcw=15. If stringer S–15, S–16, or S–17 is cracked in this area and there is a crack in the skin adjacent to the stringer crack, the skin crack could grow to a critical length before it can be found by routine maintenance inspections. This condition, if not corrected, could result in structural failure of the wings. We are issuing this AD to correct the unsafe condition on these products. E:\FR\FM\11APR1.SGM 11APR1 21254 Federal Register / Vol. 81, No. 69 / Monday, April 11, 2016 / Rules and Regulations Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin MD80–57A244, dated March 3, 2016. The service information describes procedures for repetitive ETHF inspections for any cracking in the left and right side center wing lower skin, 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. FAA’s Determination We are issuing 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. AD Requirements This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this 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–2016– 5458. The phrase ‘‘corrective actions’’ is used in this AD. Corrective actions correct or address any condition found. Corrective actions in an AD could include, for example, repairs. Differences Between This AD and the Service Information Boeing Alert Service Bulletin MD80– 57A244, dated March 3, 2016, specifies to contact the manufacturer for certain instructions, but this AD requires accomplishment of repair methods, modification deviations, and alteration deviations in one of the following ways: • In accordance with a method that we approve; or • Using data that meet the certification basis of the airplane, and that have been approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) whom we have authorized to make those findings. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because we have received reports indicating cracking at certain stringers, associated end fittings, and skins in the center wing fuel tank where the stringers meet the end fittings. This condition, if not corrected, could cause structural failure of the wings. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2016–5458 and Directorate Identifier 2016–NM–027–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this 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 AD. Costs of Compliance We estimate that this AD affects 395 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Inspection ........... 14 work-hours × $85 per hour = $1,190 per inspection cycle. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. jstallworth on DSK7TPTVN1PROD with RULES 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 VerDate Sep<11>2014 14:13 Apr 08, 2016 Jkt 238001 Cost per product $0 $1,190 per inspection cycle .......... 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 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, PO 00000 Frm 00032 Fmt 4700 Cost on U.S. operators Sfmt 4700 $470,050 per inspection cycle. (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: E:\FR\FM\11APR1.SGM 11APR1 Federal Register / Vol. 81, No. 69 / Monday, April 11, 2016 / Rules and Regulations PART 39—AIRWORTHINESS DIRECTIVES 1.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

SUMMARY: We are adopting a new airworthiness directive (AD) for all The 
Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), 
and DC-9-87 (MD-87) airplanes, and Model MD-88 airplanes. This AD 
requires repetitive eddy current high frequency (ETHF) inspections for 
any cracking in the left and right side center wing lower skin, and 
corrective actions if necessary. This AD was prompted by reports of 
cracking at certain stringers, associated end fittings, and skins in 
the center wing fuel tank where the stringers meet the end fittings. We 
are issuing this AD to detect and correct cracking in the center wing 
lower skin. Such cracking could cause structural failure of the wings.

SUPPLEMENTARY INFORMATION:

Discussion

    We have received reports of cracks at stringers S-15, S-16, or S-
17, associated end fittings, and skins in the center wing fuel tank 
where the stringers meet the end fittings near Xcw=13 and Xcw=15. If 
stringer S-15, S-16, or S-17 is cracked in this area and there is a 
crack in the skin adjacent to the stringer crack, the skin crack could 
grow to a critical length before it can be found by routine maintenance 
inspections. This condition, if not corrected, could result in 
structural failure of the wings. We are issuing this AD to correct the 
unsafe condition on these products.

[[Page 21254]]

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin MD80-57A244, dated March 
3, 2016. The service information describes procedures for repetitive 
ETHF inspections for any cracking in the left and right side center 
wing lower skin, 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.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously, except as discussed under 
``Differences Between this 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-2016-5458.
    The phrase ``corrective actions'' is used in this AD. Corrective 
actions correct or address any condition found. Corrective actions in 
an AD could include, for example, repairs.

Differences Between This AD and the Service Information

    Boeing Alert Service Bulletin MD80-57A244, dated March 3, 2016, 
specifies to contact the manufacturer for certain instructions, but 
this AD requires accomplishment of repair methods, modification 
deviations, and alteration deviations in one of the following ways:
     In accordance with a method that we approve; or
     Using data that meet the certification basis of the 
airplane, and that have been approved by the Boeing Commercial 
Airplanes Organization Designation Authorization (ODA) whom we have 
authorized to make those findings.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because we 
have received reports indicating cracking at certain stringers, 
associated end fittings, and skins in the center wing fuel tank where 
the stringers meet the end fittings. This condition, if not corrected, 
could cause structural failure of the wings.
    Therefore, we find that notice and opportunity for prior public 
comment are impracticable and that good cause exists for making this 
amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2016-5458 and 
Directorate Identifier 2016-NM-027-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
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 AD.

Costs of Compliance

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

    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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

[[Page 21255]]

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2016-07-28 The Boeing Company: Amendment 39-18473; Docket No. FAA-
2016-5458; Directorate Identifier 2016-NM-027-AD.

(a) Effective Date

    This AD is effective April 26, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model DC-9-81 (MD-81), 
DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes, and 
Model MD-88 airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Unsafe Condition

    This AD was prompted by reports of cracking at certain 
stringers, associated end fittings, and skins in the center wing 
fuel tank where the stringers meet the end fittings. We are issuing 
this AD to detect and correct cracking in the center wing lower 
skin. Such cracking could cause structural failure of the wings.

(f) Compliance

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

(g) Inspection

    Except as required by paragraph (h)(1) and (h)(2) of this AD, at 
the applicable time specified in paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin MD80-57A244, dated March 3, 2016: Do 
an eddy current high frequency (ETHF) inspection for any cracking in 
the left and right side center wing lower skin, and do all 
applicable corrective actions; except as required by paragraph 
(h)(3) of this AD. Do all applicable corrective actions before 
further flight. Repeat the inspection thereafter at the intervals 
specified in paragraph 1.E., ``Compliance,'' of Boeing Alert Service 
Bulletin MD80-57A244, dated March 3, 2016.

(h) Exception to the Service Information

    (1) Where Boeing Alert Service Bulletin MD80-57A244, dated March 
3, 2016, 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.
    (2) The Condition column of paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin MD80-57A244, dated March 3, 2016, 
refers to total flight cycles ``as of the original issue date of 
this service bulletin.'' This AD, however, applies to the airplanes 
with the specified total flight cycles as of the effective date of 
this AD.
    (3) If any crack is found during any inspection required by this 
AD, and Boeing Alert Service Bulletin MD80-57A244, dated March 3, 
2016, specifies to contact Boeing for appropriate action, and 
specifies that action as ``RC'' (Required for Compliance): Before 
further flight, repair using a method approved in accordance with 
the procedures specified in paragraph (i) of this AD.

(i) 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 (j) 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, 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, Los Angeles 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) Except as required by paragraph (h)(3) of this AD: For 
service information that contains steps that are labeled as Required 
for Compliance (RC), the provisions of paragraphs (i)(4)(i) and 
(i)(4)(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.
