The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767–200 and –300 series airplanes. This proposed AD was prompted by a report of two cracks at a certain frame inner chord. This proposed AD would require a detailed inspection for any material review board (MRB) filler installed in the area from the frame web to the stubbeam fitting at certain stations to determine if the filler extends above the frame-to-stub-beam joint, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by January 22, 2018. 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. Follow the instructions for submitting comments. • Fax: 202–493–2251. • Mail: U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590. • Hand Delivery: Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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– 2017–1099; Product Identifier 2017– NM–093–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this NPRM. We will consider all comments received by the closing date and may amend this NPRM 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 PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 substantive verbal contact we receive about this proposed AD. Discussion We have received a report of a crack on the transition radius of the station (STA) 883.5 frame inner chord and an additional crack indication at a fastener hole in the frame inner chord common to a MRB filler that extended above the frame-to-stub-beam joint. Extending the MRB filler above the frame-to-stub-beam joint changes the critical fastener location. For this configuration of the overwing frame-to-stub-beam joint, the upper-lobe-interior-structural and internal zonal (general visual) inspections in the existing baseline maintenance program together with supplemental structural inspections of the overwing stub frames are not adequate to reliably detect a crack in the frame inner chord before the crack grows to a critical length. This condition, if not corrected, could result in the inability of one or more overwing stub frames between STA 808 and STA 933, each a principal structural element, to sustain limit load, which could adversely affect the structural integrity of the airplane. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Requirements Bulletin 767–53A0278 RB, dated June 30, 2017. The service information describes procedures for a detailed inspection for any MRB filler installed in the area from the frame web to the stub-beam fitting on the left and right side at STA 859.5, 883.5, and 903.5 to determine if the filler extends above the frame-to-stub-beam joint, and applicable on-condition actions. The applicable on-condition actions include repetitive surface high frequency eddy current inspections and repair for cracking in the frame inner chord around the end fastener common to each affected MRB filler. 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 E:\FR\FM\06DEP1.SGM 06DEP1 57553 Federal Register / Vol. 82, No. 233 / Wednesday, December 6, 2017 / Proposed Rules enhancement is a process for annotating which steps in the service information are ‘‘required for compliance’’ (RC) with an AD. Boeing has implemented this RC concept into Boeing service bulletins. In an effort to further improve the quality of ADs and AD-related Boeing service information, a joint process improvement initiative was worked between the FAA and Boeing. The initiative resulted in the development of a new process in which the service information more clearly identifies the actions needed to address the unsafe condition in the ‘‘Accomplishment Instructions.’’ The new process results in a Boeing Requirements Bulletin, which contains only the actions needed to address the unsafe condition (i.e., only the RC actions). Proposed AD Requirements This proposed AD would require accomplishment of the actions identified in the Boeing Alert Requirements Bulletin 767–53A0278 RB, dated June 30, 2017, described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 1099. Explanation of Requirements Bulletin The FAA worked in conjunction with industry, under the Airworthiness Directive Implementation Aviation Rulemaking Committee (AD ARC), to enhance the AD system. One identified in Boeing Alert Requirements Bulletin 767–53A0278 RB, dated June 30, 2017, may be modified to a freighter configuration per certain supplemental type certificates. For the modified airplanes, in lieu of accomplishing the actions specified in Boeing Alert Requirements Bulletin 767–53A0278 RB, dated June 30, 2017, for Group 1, Configuration 1, and Group 2, Configuration 1, the actions specified in Boeing Alert Requirements Bulletin 767–53A0278 RB, dated June 30, 2017, for Group 1, Configuration 2, and Group 2, Configuration 2, as applicable, must be done. We have coordinated this difference with Boeing. Differences Between This Proposed AD and the Service Information Airplanes in Group 1, Configuration 1, and Group 2, Configuration 1, as develop in other products of the same type design. We estimate that this proposed AD affects 51 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Costs of Compliance ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Detailed Inspection ................. 20 work-hours × $85 per hour = $1,700 ................................ We estimate the following costs to do any necessary on-condition actions that would be required. We have no way of Cost per product Parts cost $0 Cost on U.S. operators $1,700 $86,700 determining the number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION INSPECTIONS Labor cost Parts cost 3 work-hours × $85 per hour = $255 per inspection cycle .......................................... We have received no definitive data that would enable us to provide cost estimates for the on-condition repairs specified in this proposed AD. jstallworth on DSKBBY8HB2PROD 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 VerDate Sep<11>2014 14:39 Dec 05, 2017 Jkt 244001 $0 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 Cost per product $255 per inspection cycle. 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.

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 
certain The Boeing Company Model 767-200 and -300 series airplanes. 
This proposed AD was prompted by a report of two cracks at a certain 
frame inner chord. This proposed AD would require a detailed inspection 
for any material review board (MRB) filler installed in the area from 
the frame web to the stub-beam fitting at certain stations to determine 
if the filler extends above the frame-to-stub-beam joint, and 
applicable on-condition actions. We are proposing this AD to address 
the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by January 22, 
2018.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

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-2017-1099; 
Product Identifier 2017-NM-093-AD'' at the beginning of your comments. 
We specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this NPRM. We will consider all 
comments received by the closing date and may amend this NPRM because 
of those comments.

Discussion

    We have received a report of a crack on the transition radius of 
the station (STA) 883.5 frame inner chord and an additional crack 
indication at a fastener hole in the frame inner chord common to a MRB 
filler that extended above the frame-to-stub-beam joint. Extending the 
MRB filler above the frame-to-stub-beam joint changes the critical 
fastener location. For this configuration of the overwing frame-to-
stub-beam joint, the upper-lobe-interior-structural and internal zonal 
(general visual) inspections in the existing baseline maintenance 
program together with supplemental structural inspections of the 
overwing stub frames are not adequate to reliably detect a crack in the 
frame inner chord before the crack grows to a critical length. This 
condition, if not corrected, could result in the inability of one or 
more overwing stub frames between STA 808 and STA 933, each a principal 
structural element, to sustain limit load, which could adversely affect 
the structural integrity of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Requirements Bulletin 767-53A0278 RB, 
dated June 30, 2017. The service information describes procedures for a 
detailed inspection for any MRB filler installed in the area from the 
frame web to the stub-beam fitting on the left and right side at STA 
859.5, 883.5, and 903.5 to determine if the filler extends above the 
frame-to-stub-beam joint, and applicable on-condition actions. The 
applicable on-condition actions include repetitive surface high 
frequency eddy current inspections and repair for cracking in the frame 
inner chord around the end fastener common to each affected MRB filler. 
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

[[Page 57553]]

develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishment of the actions 
identified in the Boeing Alert Requirements Bulletin 767-53A0278 RB, 
dated June 30, 2017, described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD.
    For information on the procedures and compliance times, see this 
service information at http://www.regulations.gov by searching for and 
locating Docket No. FAA-2017-1099.

Explanation of Requirements Bulletin

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive Implementation Aviation Rulemaking Committee 
(AD ARC), to enhance the AD system. One enhancement is a process for 
annotating which steps in the service information are ``required for 
compliance'' (RC) with an AD. Boeing has implemented this RC concept 
into Boeing service bulletins.
    In an effort to further improve the quality of ADs and AD-related 
Boeing service information, a joint process improvement initiative was 
worked between the FAA and Boeing. The initiative resulted in the 
development of a new process in which the service information more 
clearly identifies the actions needed to address the unsafe condition 
in the ``Accomplishment Instructions.'' The new process results in a 
Boeing Requirements Bulletin, which contains only the actions needed to 
address the unsafe condition (i.e., only the RC actions).

Differences Between This Proposed AD and the Service Information

    Airplanes in Group 1, Configuration 1, and Group 2, Configuration 
1, as identified in Boeing Alert Requirements Bulletin 767-53A0278 RB, 
dated June 30, 2017, may be modified to a freighter configuration per 
certain supplemental type certificates. For the modified airplanes, in 
lieu of accomplishing the actions specified in Boeing Alert 
Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, for Group 1, 
Configuration 1, and Group 2, Configuration 1, the actions specified in 
Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, 
for Group 1, Configuration 2, and Group 2, Configuration 2, as 
applicable, must be done. We have coordinated this difference with 
Boeing.

Costs of Compliance

    We estimate that this proposed AD affects 51 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                      Estimated Costs for Required Actions

                                      hour = $1,700.
----------------------------------------------------------------------------------------------------------------

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

               Estimated Costs of On-Condition Inspections
------------------------------------------------------------------------
            Labor cost                Parts cost      Cost per product
------------------------------------------------------------------------
3 work-hours x $85 per hour = $255              $0  $255 per inspection
 per inspection cycle.                               cycle.
------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition repairs 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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

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.

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

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-2017-1099; Product Identifier 
2017-NM-093-AD.

(a) Comments Due Date

    We must receive comments by January 22, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 767-200 and -300 
series airplanes, as identified in Boeing Alert Requirements 
Bulletin 767-53A0278 RB, dated June 30, 2017, certificated in any 
category.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by a report of a crack on the transition 
radius of the station (STA) 883.5 frame inner chord and an 
additional crack indication at a fastener hole in the frame inner 
chord common to a material review board (MRB) filler that extended 
above the frame-to-stub-beam joint. We are issuing this AD to detect 
and correct cracking of the frame inner chord, which could result in 
the inability of one or more overwing stub frames between STA 808 
and STA 933, each a principal structural element, to sustain limit 
load; this condition could adversely affect the structural integrity 
of the airplane.

(f) Compliance

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

(g) Required Actions

    Except as required by paragraph (h) of this AD: At the 
applicable times specified in the ``Compliance'' paragraph of Boeing 
Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, do 
all applicable actions identified in, and in accordance with, the 
Accomplishment Instructions of Boeing Alert Requirements Bulletin 
767-53A0278 RB, dated June 30, 2017.
    Note 1 to paragraph (g) of this AD: Guidance for accomplishing 
the actions required by this AD can be found in Boeing Alert Service 
Bulletin 767-53A0278, dated June 30, 2017, which is referred to in 
Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 
2017.

(h) Exceptions to Service Information Specifications

    (1) For purposes of determining compliance with the requirements 
of this AD, the phrase ``the effective date of this AD'' may be 
substituted for ``the original issue date of Requirements Bulletin 
767-53A0278 RB'' as specified in Boeing Alert Requirements Bulletin 
767-53A0278 RB, dated June 30, 2017.
    (2) Where Boeing Alert Requirements Bulletin 767-53A0278 RB, 
dated June 30, 2017, specifies contacting Boeing, this AD requires 
repair using a method approved in accordance with the procedures 
specified in paragraph (i) of this AD.
    (3) For airplanes identified as Group 1, Configuration 1, in 
Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 
2017, that have been modified to a freighter configuration: The 
actions specified in Boeing Alert Requirements Bulletin 767-53A0278 
RB, dated June 30, 2017, for Group 1, Configuration 2, must be done 
instead of the actions for Group 1, Configuration 1, except as 
required by paragraph (h)(2) of this AD.
    (4) For airplanes identified as Group 2, Configuration 1, in 
Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30,
