SUPPLEMENTARY INFORMATION: Comments Invited The FAA invites 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–2019–0871; Product Identifier 2019–NM–139–AD’’ at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this NPRM. The FAA will consider all comments received by the closing date and may amend this NPRM because of those comments. The FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact received about this proposed AD. Discussion The FAA has received a report indicating fatigue cracks were found at 3 of 8 frame tie rod locations in Section 11 of the wing during full-scale fatigue testing. The cracks were located at the frame tie rod end lugs or in the typical frame tie rod section. At 77,640 fatigue test cycles, the right-side station (STA) 1089 corrosion resistant steel (CRES) frame tie rod lug had failed and was replaced. At 132,000 fatigue test cycles, PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 63825 the left-side STA 1041 aluminum frame tie rod had failed in the typical section, and was replaced. At 152,879 fatigue test cycles, the left-side STA 1089 CRES frame tie rod lug had failed and was replaced. This condition, if not addressed, could result in failure of a principal structural element to sustain limit load, which could adversely affect the structural integrity of the airplane and result in possible decompression of the airplane. Related Service Information Under 1 CFR Part 51 The FAA reviewed Boeing Alert Requirements Bulletin B787–81205– SB570041–00 RB, Issue 001, dated March 7, 2019. The service information describes procedures for repetitive high frequency eddy current (HFEC) inspections for cracking of the left- and right-side frame tie rod assemblies, and repetitive ultrasonic (UT) inspections for cracking of the left- and right-side stub beam upper chords, and applicable on-condition actions. On-condition actions include repair. 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 The FAA is proposing this AD because the agency 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 require accomplishment of the actions identified in Boeing Alert Requirements Bulletin B787–81205–SB570041–00 RB, Issue 001, dated March 7, 2019, described previously. 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–2019– 0871. 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. E:\FR\FM\19NOP1.SGM 19NOP1 63826 Federal Register / Vol. 84, No. 223 / Tuesday, November 19, 2019 / Proposed Rules 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). Costs of Compliance The FAA estimates that this proposed AD affects 55 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Inspections ...... 19 work-hours × $85 per hour = $1,615 per inspection cycle. The FAA has received no definitive data that would enable the agency to provide cost estimates for the oncondition actions specified in this proposed AD. khammond on DSKJM1Z7X2PROD 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. The FAA is 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 and associated appliances to the Director of the System Oversight Division. Regulatory Findings The FAA 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 VerDate Sep<11>2014 16:09 Nov 18, 2019 Jkt 250001 Parts cost Cost per product $0 $1,615 per inspection cycle.

Discussion

    The FAA has received a report indicating fatigue cracks were found 
at 3 of 8 frame tie rod locations in Section 11 of the wing during 
full-scale fatigue testing. The cracks were located at the frame tie 
rod end lugs or in the typical frame tie rod section. At 77,640 fatigue 
test cycles, the right-side station (STA) 1089 corrosion resistant 
steel (CRES) frame tie rod lug had failed and was replaced. At 132,000 
fatigue test cycles, the left-side STA 1041 aluminum frame tie rod had 
failed in the typical section, and was replaced. At 152,879 fatigue 
test cycles, the left-side STA 1089 CRES frame tie rod lug had failed 
and was replaced. This condition, if not addressed, could result in 
failure of a principal structural element to sustain limit load, which 
could adversely affect the structural integrity of the airplane and 
result in possible decompression of the airplane.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin B787-81205-
SB570041-00 RB, Issue 001, dated March 7, 2019. The service information 
describes procedures for repetitive high frequency eddy current (HFEC) 
inspections for cracking of the left- and right-side frame tie rod 
assemblies, and repetitive ultrasonic (UT) inspections for cracking of 
the left- and right-side stub beam upper chords, and applicable on-
condition actions. On-condition actions include repair. 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

    The FAA is proposing this AD because the agency 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 require accomplishment of the actions 
identified in Boeing Alert Requirements Bulletin B787-81205-SB570041-00 
RB, Issue 001, dated March 7, 2019, described previously.
    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-2019-0871.

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.

[[Page 63826]]

    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).

Costs of Compliance

    The FAA estimates that this proposed AD affects 55 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

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

    The FAA has received no definitive data that would enable the 
agency 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.
    The FAA is 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 and associated appliances to the 
Director of the System Oversight Division.

Regulatory Findings

    The FAA 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) Will not affect intrastate aviation in Alaska, and
    (3) 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

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-2019-0871; Product Identifier 
2019-NM-139-AD.

(a) Comments Due Date

    The FAA must receive comments by January 3, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 787-8 airplanes, 
certificated in any category, as identified in Boeing Alert

March 7, 2019.

(d) Subject

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

(e) Unsafe Condition

    This AD was prompted by a report of fatigue cracking at certain 
frame tie rod locations of the wing. The FAA is issuing this AD to 
address cracking in the frame tie rod assemblies and consequent 
failure of a principal structural element to sustain limit load, 
which could adversely affect the structural integrity of the 
airplane and result in possible decompression of the airplane.

(f) Compliance

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

(g) Required Actions

    Except as specified by paragraph (h) of this AD: At the 
applicable times specified in the ``Compliance'' paragraph of Boeing 
Alert Requirements Bulletin B787-81205-SB570041-00 RB, Issue 001, 
dated March 7, 2019, do all applicable actions identified in, and in 
accordance with, the Accomplishment Instructions of Boeing Alert 
Requirements Bulletin B787-81205-SB570041-00 RB, Issue 001, dated 
March 7, 2019.

    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 B787-81205-SB570041-00, Issue 001, dated March 7, 2019, 
which is referred to in Boeing Alert Requirements Bulletin B787-
81205-SB570041-00 RB, Issue 001, dated March 7, 2019.

(h) Exceptions to Service Information Specifications

    (1) For purposes of determining compliance with the requirements 
of this AD: Where Boeing Alert Requirements Bulletin B787-81205-
SB570041-00 RB, Issue 001, dated March 7, 2019, uses the phrase 
``the issue 001 date of Requirements Bulletin B787-81205-SB570041-00 
RB,'' this AD requires using the effective date of this AD.
    (2) Where Boeing Alert Requirements Bulletin B787-81205-
SB570041-00 RB, Issue 001, dated March 7, 2019, specifies contacting 
Boeing for repair instructions:

[[Page 63827]]

This AD requires doing the repair and applicable on-condition 
actions before further flight 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, Seattle ACO Branch, 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

    (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 Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Seattle 
ACO Branch, FAA, 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.
