ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain The Boeing Company Model 757-200, -200CB, and -300 series
airplanes. This AD was prompted by reports of cracks initiating in the
fuselage frame web at body station (STA) 1640. This AD requires,
depending on configuration, a general visual inspection for any
previous repair, such as any reinforcing repair or local frame
replacement repair, repetitive open hole high frequency eddy current
(HFEC) inspections for any crack of the fuselage frame web fastener
holes, on the left and right side of the airplane, and applicable on-
condition actions. The FAA is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective January 13, 2020.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of January 13,
2020.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain The Boeing
Company Model 757-200, -200CB, and -300 series airplanes. The NPRM
published in the Federal Register on June 21, 2019 (84 FR 29102). The
NPRM was prompted by reports of cracks initiating in the fuselage frame
web at STA 1640. The NPRM proposed to require, depending on
configuration, a general visual inspection for any previous repair,
such as any reinforcing repair or local frame replacement repair,
repetitive open hole HFEC inspections for any crack of the fuselage
frame web fastener holes, on the left and right side of the airplane,
and applicable on-condition actions.
The FAA is issuing this AD to address cracks initiating in the
fuselage frame web at STA 1640, which could result in reduced
structural integrity of the airplane.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Support for the NPRM
United Airlines and Aviation Partners Boeing (APB) provided their
concurrence with the NPRM.
Request To Clarify Costs of Required Actions
Boeing requested that the FAA clarify the costs of the actions
required by the NPRM by separating the access and close-out hours as
separate actions, and specifying that the on-condition costs are
providing the costs of oversizing fastener holes, if necessary. Boeing
pointed out that the costs listed also include the access and close-out
hours, which comprise the majority of the hours for each action,
causing the required actions to appear overly expensive. Boeing
mentioned that operators are expected to do either a one-time general
visual inspection, followed by an open hole HFEC inspection, or do an
open hole HFEC inspection, depending on the condition and utilization
rate of the airplane. Boeing also pointed out that the on-condition
costs are not defined in the service information and that the NPRM is
unclear if the on-condition costs refer to fastener replacement
installations or fastener hole oversizing. Additionally, Boeing
mentioned that the costs of fastener re-installation are already
included in the costs for an open hole HFEC inspection. However, Boeing
stated that the FAA estimate of one work-hour per airplane for on-
condition costs of oversizing fastener holes seems reasonable.
The FAA agrees with the request to clarify the costs of the actions
required by this AD for the reasons provided. The FAA has revised the
cost estimates provided in this AD to clarify the costs of the required
actions to include access and close-out hours only as part of the costs
for the HFEC inspections, and to revise the work-hours for the general
visual inspection to specify only 1 work-hour. We have also revised the
cost estimates in this AD to specify that the on-condition costs are
the costs of oversizing fastener holes.
Request To Clarify the Unsafe Condition
Boeing requested that the FAA clarify the unsafe condition. Boeing
pointed out that the unsafe condition mitigated by the proposed AD is
for cracks initiating in the fuselage frame web at STA 1640 in hidden
areas that may not be sufficiently detectable by doing the
[[Page 67180]]
actions specified in Boeing Alert Service Bulletin 757-53A0108.
The FAA agrees that clarification is necessary and that the actions
specified in Boeing Alert Service Bulletin 757-53A0108 are not adequate
for reliable detection of cracks that initiate in the fuselage frame
web at STA 1640. AD 2018-06-07, Amendment 39-19227 (83 FR 13398, March
29, 2018) (``AD 2018-06-07'') requires inspections in accordance with
Boeing Alert Service Bulletin 757-53A0108, dated November 14, 2016.
However, the FAA does not agree that referring to hidden areas is
clarifying, because the term ``hidden areas'' is vague. The FAA has
revised the unsafe condition specified in paragraph (e) of this AD to
specify that this AD is addressing cracks initiating in the fuselage
frame web at STA 1640, which, if not detected and corrected, could
result in reduced structural integrity of the airplane.
Request To Clarify the Types of Winglets Specified in the Proposed AD
Boeing requested that the FAA revise paragraph (g)(2) of the
proposed AD to clarify the types of winglets that may be installed on
The Boeing Company Model 757 airplanes. Boeing pointed out that the
types of winglets described in Supplemental Type Certificate (STC)
ST01518SE and in APB's service bulletin AP757-53-002 are specified as
``blended and scimitar blended winglets,'' not ``scimitar winglets.''
Boeing also pointed out that paragraph (g)(2) of the proposed AD
referred to ``blended or scimitar winglets.''
The FAA agrees for the reasons provided and has revised paragraph
(g)(2) of this AD accordingly.
Request To Specify That Certain Freighter Conversion Airplanes Perform
the Actions Specified for Groups 2 and 5
FedEx and VT Mobile Aerospace Engineering (MAE) Inc., requested
that the FAA revise the NPRM to specify that Group 1 and 4 airplanes
that have been modified to freighter configuration using VT MAE Inc.
STC ST03562AT, perform the actions specified for Groups 2 and 5, as
specified in Boeing Alert Requirements Bulletin 757-53A0112 RB, dated
November 16, 2018. VT MAE Inc. pointed out that at the STA 1640 frame,
in the stringer 14 left hand side and right hand side area, the
modification to freighter configuration using VT MAE Inc. STC
ST03562AT, is identical to that of The Boeing Company Model 757-200
special freighter airplanes identified as Groups 2 and 5 in Boeing
Alert Requirements Bulletin 757-53A0112 RB, dated November 16, 2018.
FedEx noted that its fleet of The Boeing Company Model 757-200
airplanes were converted to a configuration similar to The Boeing
Company Model 757-200 special freighter airplanes, and are no longer
configured as passenger airplanes. FedEx pointed out that as written,
Boeing Alert Requirements Bulletin 757-53A0112 RB, dated November 16,
2018, Groups the FedEx fleet into Groups 1 and 4, and that the
inspection areas for those Groups are no longer applicable. FedEx
requested that the FAA incorporate its suggested changes into the final
rule to avoid the need for an alternative method of compliance (AMOC)
after issuance of the final rule.
The FAA agrees with the request for the reasons provided. The FAA
has added paragraphs (g)(3) and (g)(4) of this AD to require, for
airplanes that have been converted from passenger to freighter
configuration using VT MAE Inc. STC ST03562AT, the actions required for
Groups 2 and 5, as applicable, as specified in Boeing Alert
Requirements Bulletin 757-53A0112 RB, dated November 16, 2018.
Request To Terminate the Inspection Requirements if a Repair Is
Installed for a Crack Finding
FedEx requested that the FAA allow termination of the inspection
requirements if a repair is installed for a crack finding. FedEx
pointed out that if a repair is installed for a crack finding, the
repair instructions obtained from The Boeing Company Organization
Designation Authorization (ODA), the STC holder, or the FAA would have
repetitive inspection requirements separate from those specified in the
NPRM. The FAA infers that FedEx is requesting termination of the
inspection requirements to help avoid overlapping inspections in a
repaired area.
The FAA disagrees with the request to allow termination of the
inspection requirements if a repair is installed for a crack finding.
At this time, the service information does not include an approved
repair that resolves the unsafe condition addressed by this AD.
Inspections for repairs required by FAA regulations address structural
failure due to fatigue, corrosion, manufacturing defects, or accidental
damage, and do not resolve unsafe conditions that are addressed by an
AD. If a repair is required for cracks found during inspections
required by this AD, the FAA will consider requests for approval of an
AMOC.
Request To Specify That an AMOC for a Certain Other AD Is Necessary
FedEx requested that the FAA include a statement in paragraph (i)
of the proposed AD specifying that if a repair is required for a crack
found during inspections required by the NPRM, that an AMOC for AD
2018-06-07 is required. FedEx mentioned that it has already experienced
a situation that when repairing a crack found using Boeing Alert
Requirements Bulletin 757-53A0112 RB, dated November 16, 2018, an AMOC
to AD 2018-06-07 was required to complete the repair.
The FAA disagrees with the request to include a statement in
paragraph (j) of this AD (which was referred to as paragraph (i) of the
proposed AD) specifying that if a repair is required for a crack found
during inspections required by this AD, that an AMOC for AD 2018-06-07
is required. However, any repair in this area that affects compliance
with this AD, with AD 2018-06-07, or with both ADs, will require an
AMOC to comply with the requirements of the affected ADs. The FAA has
included note 2 to paragraphs (g)(1) through (4) of this AD to denote
that certain repairs might affect AD 2018-06-07.
Request To Allow Later Revisions to the Service Information
John Straiton requested that the FAA revise the proposed AD to
allow the use of later revisions to the service information. The
commenter pointed out that allowing the use of later revisions would
make it easier for the operator to ensure compliance and that all
maintenance is certified to the latest maintenance data. The commenter
also mentioned that allowing the use of later revisions would make it
unnecessary for operators to wait for new ADs that include the latest
revisions to the service information, or for operators to request an
AMOC that allows the use of the latest revisions to the service
information. The commenter stated that this would reduce the delay in
implementation of the latest revisions to the service information and
also reduce the maintenance costs associated with the issuance of
AMOCs. The commenter also pointed out that the European Union Aviation
Safety Agency (EASA) incorporates similar language in its ADs.
The FAA disagrees with the request to allow later revisions to the
service information. The FAA may not refer to any document that does
not yet exist in an AD. In general terms, the FAA is required by Office
of the Federal Register (OFR) regulations for approval of materials
incorporated by reference,
[[Page 67181]]
as specified in 1 CFR 51.1(f), to either publish the service document
contents as part of the actual AD language; or submit the service
document to the OFR for approval as referenced material, in which case
the FAA may only refer to such material in the text of an AD. The AD
may refer to the service document only if the OFR approved it for
incorporation by reference. See 1 CFR part 51.
To allow operators to use later revisions of the referenced
document (issued after publication of the AD), either the FAA must
revise the AD to reference specific later revisions, or the affected
party must request approval to use later revisions as an AMOC with this
AD under the provisions of paragraph (j) of this AD.
Request for an Exception to Certain Service Information
American Airlines (AAL) and APB requested that the FAA revise the
proposed AD to include a new exception. AAL requested that the FAA
include an exception that specifies ``Where APB Alert Service Bulletin
AP757-53-002, Revision 2, dated April 11, 2019, uses the phrase the
original issue of Service Bulletin AP757-53-001, this AD requires using
the original issue, or Revision 1, of Service Bulletin AP757-53-001.''
APB pointed out that the original issue of APB Service Bulletin AP757-
53-001, was withdrawn. APB also stated their support for AAL's request.
AAL also pointed out that while APB Alert Service Bulletin AP757-
53-002, Revision 2, dated April 11, 2019, specifies the original issue
of APB Service Bulletin AP757-53-001, AD 2018-06-07 requires operators
to use Revision 1 of APB Service Bulletin AP757-53-001. AAL noted that
this creates conflicting verbiage between the NPRM and AD 2018-06-07.
The FAA agrees to clarify. The FAA notes that APB Alert Service
Bulletin AP757-53-002, Revision 3, dated August 14, 2019, has been
issued to correct the reference from the original issue of APB Service
Bulletin AP757-53-001 to Revision 1 of APB Service Bulletin AP757-53-
001, as it relates to whether inspections have previously been done. No
additional work is required for airplanes on which the actions
specified in this AD were done using APB Alert Service Bulletin AP757-
53-002, Revision 2, dated April 11, 2019. The FAA has revised this
final rule to refer to APB Alert Service Bulletin AP757-53-002,
Revision 3, dated August 14, 2019, as the appropriate source of service
information for compliance with this AD, and to provide credit for
actions done before the effective date of this AD using APB Alert
Service Bulletin AP757-53-002, Revision 2, dated April 11, 2019.
Conclusion
The FAA has reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule with the changes described previously
and minor editorial changes. The FAA has determined that these minor
changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
The FAA also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

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 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
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) 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.

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