We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We have received a report of a fuel leak in a Model C–118A airplane. The fuel leak, discovered during a post-flight inspection, resulted from a crack in the wing lower skin just inboard of the number 2 nacelle attach angle at wing station 175. Related AD 80–12–02 R1, Amendment 39–5499, applies to Model DC–6, DC–6A, DC–6B, R6D, and C–118 series airplanes. AD 80–12–02 R1 requires repetitive inspections for cracking of the left and right wing lower skin at certain locations. Although wing station 175 is covered by the inspection mandated in AD 80–12–02 R1, the crack was missed during an AD-required inspection. Boeing Alert Service Bulletin DC6– 57A001, dated April 28, 2016 (‘‘ASB DC6–57A001, Revision 0’’) is an alternative method of compliance (AMOC) to the inspections required by paragraph (c)(1) of AD 80–12–02 R1. This AMOC only applies to the areas inspected in accordance with ASB DC6– 57A001, Revision 0. The service information referenced in this NPRM contains revised inspection procedures for crack detection in the area around wing station 175. Such cracking in the E:\FR\FM\26OCP1.SGM 26OCP1 Federal Register / Vol. 81, No. 207 / Wednesday, October 26, 2016 / Proposed Rules wing lower skin could adversely affect the structural integrity of the wing. develop in other products of these same type designs. Related Service Information Under 1 CFR Part 51 We reviewed ASB DC6–57A001, Revision 0. The service information describes procedures for radiographic, ETHF, and ETLF inspections for cracking of the wing lower skin at station 175, and repairs. 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. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this Proposed AD and the Service Information.’’ For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 9300. 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 Differences Between This Proposed AD and the Service Information ASB DC6–57A001, Revision 0, specifies to contact the manufacturer for certain instructions, but this proposed 74353 AD would require 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. Costs of Compliance We estimate that this proposed AD affects 36 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Inspections ......... 17 work-hours × $85 per hour = $1,445 per inspection cycle. $0 $1,445 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 proposed AD. Authority for This Rulemaking Lhorne on DSK30JT082PROD with PROPOSALS 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 VerDate Sep<11>2014 15:05 Oct 25, 2016 Jkt 241001 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 Cost on U.S. operators § 39.13 $52,020 per inspection cycle. [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ The Boeing Company: Docket No. FAA– 2016–9300; Directorate Identifier 2016– NM–124–AD. (a) Comments Due Date We must receive comments by December 12, 2016. (b) Affected ADs None. (c) Applicability This AD applies to all The Boeing Company Model DC–6, DC–6A, DC–6B, C– 118A, R6D–1, and R6D–1Z airplanes, certificated in any category. (d) Subject Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Air Transport Association (ATA) of America Code 57, Wings. The Proposed Amendment This AD was prompted by a report of a fuel leak in a Model C–118A airplane that resulted from a crack in the wing lower skin just inboard of the number 2 nacelle attach angle at wing station 175. We are issuing this AD to detect and correct fatigue cracking in the wing lower skin, which could adversely affect the structural integrity of the wing. 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 (e) Unsafe Condition (f) Compliance 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701.

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 DC-6, DC-6A, C-118A, R6D-1, DC-6B, and R6D-1Z 
airplanes. This proposed AD was prompted by a report of a fuel leak in 
a Model C-118A airplane that resulted from a crack in the wing lower 
skin. This proposed AD would require repetitive radiographic, 
electromagnetic testing high frequency (ETHF), and electromagnetic 
testing low frequency (ETLF) inspections for cracking of the wing lower 
skin, and repairs if necessary. We are proposing this AD to detect and 
correct fatigue cracking in the wing lower skin, which could adversely 
affect the structural integrity of the wing.

DATES: We must receive comments on this proposed AD by December 12, 
2016.

Discussion

    We have received a report of a fuel leak in a Model C-118A 
airplane. The fuel leak, discovered during a post-flight inspection, 
resulted from a crack in the wing lower skin just inboard of the number 
2 nacelle attach angle at wing station 175.
    Related AD 80-12-02 R1, Amendment 39-5499, applies to Model DC-6, 
DC-6A, DC-6B, R6D, and C-118 series airplanes. AD 80-12-02 R1 requires 
repetitive inspections for cracking of the left and right wing lower 
skin at certain locations. Although wing station 175 is covered by the 
inspection mandated in AD 80-12-02 R1, the crack was missed during an 
AD-required inspection.
    Boeing Alert Service Bulletin DC6-57A001, dated April 28, 2016 
(``ASB DC6-57A001, Revision 0'') is an alternative method of compliance 
(AMOC) to the inspections required by paragraph (c)(1) of AD 80-12-02 
R1. This AMOC only applies to the areas inspected in accordance with 
ASB DC6-57A001, Revision 0. The service information referenced in this 
NPRM contains revised inspection procedures for crack detection in the 
area around wing station 175. Such cracking in the

[[Page 74353]]

wing lower skin could adversely affect the structural integrity of the 
wing.

Related Service Information Under 1 CFR Part 51

    We reviewed ASB DC6-57A001, Revision 0. The service information 
describes procedures for radiographic, ETHF, and ETLF inspections for 
cracking of the wing lower skin at station 175, and repairs. This 
service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

FAA's Determination

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

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between this Proposed AD and the Service 
Information.'' For information on the procedures and compliance times, 
see this service information at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2016-9300.

Differences Between This Proposed AD and the Service Information

    ASB DC6-57A001, Revision 0, specifies to contact the manufacturer 
for certain instructions, but this proposed AD would require 
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.

Costs of Compliance

    We estimate that this proposed AD affects 36 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

Authority for This Rulemaking

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

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (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.

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

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):

The Boeing Company: Docket No. FAA-2016-9300; Directorate Identifier 
2016-NM-124-AD.

(a) Comments Due Date

    We must receive comments by December 12, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model DC-6, DC-6A, DC-
6B, C-118A, R6D-1, and R6D-1Z airplanes, certificated in any 
category.

(d) Subject

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

(e) Unsafe Condition

    This AD was prompted by a report of a fuel leak in a Model C-
118A airplane that resulted from a crack in the wing lower skin just 
inboard of the number 2 nacelle attach angle at wing station 175. We 
are issuing this AD to detect and correct fatigue cracking in the 
wing lower skin, which could adversely affect the structural 
integrity of the wing.

(f) Compliance

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

[[Page 74354]]

(g) Repetitive Inspections

    Except as specified in paragraph (i) of this AD: At the 
applicable time specified in paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin DC6-57A001, dated April 28, 2016 
(``ASB DC6-57A001, Revision 0''), do radiographic, electromagnetic 
testing high frequency (ETHF), and electromagnetic testing low 
frequency (ETLF) inspections for cracking of the wing lower skin at 
station 175, in accordance with the Accomplishment Instructions of 
ASB DC6-57A001, Revision 0. Repeat the radiographic, ETHF, and ETLF 
inspections of any unrepaired areas thereafter at the applicable 
intervals specified in paragraph 1.E., ``Compliance,'' of ASB DC6-
57A001, Revision 0.

(h) Repairs

    If any cracking is found during any inspection required by this 
AD: Before further flight, repair the cracking using a method 
approved in accordance with the procedures specified in paragraph 
(j) of this AD.

(i) Service information Exception

    Where paragraph 1.E., ``Compliance,'' of ASB DC6-57A001, 
Revision 0, 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.

(j) 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 (k)(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, 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) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(j)(4)(i) and (j)(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. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
