ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to
supersede Airworthiness Directive (AD)
2018–06–07, which applies to all The
Boeing Company Model 757–200,
–200CB, and –300 series airplanes. AD
2018–06–07 requires inspecting the
fuselage frame at a certain station for
existing repairs, repetitive inspections,
and applicable repairs. Since the FAA
issued AD 2018–06–07, the agency has
received reports of new crack findings
outside of the AD 2018–06–07
inspection area, which the current
inspections will not detect. This
proposed AD would continue to require
the actions in AD 2018–06–07, with an
expanded inspection area, additional
inspections, a modified inspection type,
and applicable repairs. The FAA is
proposing this AD to address the unsafe
condition on these products.
DATES: The FAA must receive comments
on this proposed AD by April 3, 2020.

crack was not in the area inspected as
required by AD 2018–06–07. There have
also been reports of cracks found
growing out of the fastener holes in the
inner chord in the aft direction, towards
the web away from the original
inspection areas. The FAA has therefore
determined that the inspection area
must be expanded and new inspections
must be added.
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–2020–0094; Product
Identifier 2019–NM–188–AD’’ at the
beginning of your comments. The FAA

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 issued AD 2018–06–07,
Amendment 39–19227 (83 FR 13398,
March 29, 2018) (‘‘AD 2018–06–07’’), for
all The Boeing Company Model 757–
200, –200CB, and –300 series airplanes.
AD 2018–06–07 requires inspecting the
fuselage frame at station (STA) 1640 for
existing repairs, repetitive inspections,
and applicable repairs. AD 2018–06–07
resulted from a report of fatigue
cracking found in a certain fuselage
frame, which severed the inner chord
and web. The FAA issued AD 2018–06–
07 to address cracking of the fuselage
frame at STA 1640, which could result
in reduced structural integrity of the
airplane.
Actions Since AD 2018–06–07 Was
Issued
Since the FAA issued AD 2018–06–
07, the FAA has received reports of new
crack findings outside of the AD 2018–
06–07 inspection area. During the
inspections required by AD 2018–06–
07, an operator found the STA 1640
frame with a crack starting from the
third fastener below the stringer S–14
intercostal on the right side. The crack
was approximately 3 inches long and
had grown into an insulation stud hole
in the web near the outer chord. The
Related Service Information Under 1
CFR Part 51
The FAA has reviewed Boeing Alert
Service Bulletin 757–53A0108, Revision
1, dated July 17, 2019. This service
information describes procedures for an
inspection of the fuselage frame for
existing frame repairs or replacements,
a detailed inspection for any crack, nick,
or gouge in the STA 1640 fuselage
frame, repetitive high frequency eddy
current and low frequency eddy current
inspections for cracking in the STA
1640 fuselage frame between stringers
S–11 and S–16, and repair.
The FAA has also reviewed Aviation
Partners Boeing (APB) Alert Service
Bulletin AP757–53–001, Revision 2,
dated October 22, 2019. This service
information provides compliance times
for accomplishing the procedures
identified in Boeing Alert Service
Bulletin 757–53A0108, Revision 1,
dated July 17, 2019, for airplanes on
which APB blended or scimitar blended
winglets are installed.
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 FAA has 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
Although this proposed AD does not
explicitly restate the requirements of AD
2018–06–07, this proposed AD would
retain certain requirements of AD 2018–
06–07. Those requirements are
referenced in the service information
identified previously, which, in turn, is
referenced in paragraph (g) of this
proposed AD. This proposed AD would
expand the inspection area, add
inspections, and modify a certain
inspection type.
This proposed AD would also require
accomplishment of the actions
identified as ‘‘RC’’ (required for
compliance) in the Accomplishment
Instructions of Boeing Alert Service
Bulletin 757–53A0108, Revision 1,
dated July 17, 2019; and Aviation
Partners Boeing (APB) Alert Service
Bulletin AP757–53–001, Revision 2,
dated October 22, 2019, described
previously, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.
The initial compliance times for the
airplanes identified in Boeing Alert
Service Bulletin 757–53A0108, Revision
1, dated July 17, 2019, range from
within 500 flight cycles after the
effective date of this AD, to within
16,000 flight cycles after the installation
of the local frame replacement,
depending on the configuration. The
repetitive intervals range from 1,800
flight cycles to 10,400 flight cycles,
depending on the configuration.
The initial compliance times for the
airplanes identified in Aviation Partners
Boeing (APB) Alert Service Bulletin
AP757–53–001, Revision 2, dated
October 22, 2019, range from within 500
flight cycles after the effective date of
this AD, to within 16,000 flight cycles
after the installation of the local frame
replacement, depending on the
configuration. The repetitive intervals
range from 1,900 flight cycles to 8,600
flight cycles, depending on the
configuration.
For information on the procedures
and compliance times, see Boeing Alert
Service Bulletin 757–53A0108, Revision
1, dated July 17, 2019, at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2020–
0094.
Costs of Compliance
The FAA estimates that this proposed
AD affects 606 airplanes of U.S. registry.
The FAA estimates 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.
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.

The FAA has received no definitive
data that would enable us to provide
cost estimates for the on-condition
repair specified in this proposed AD.
Regulatory Findings
The FAA has 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 that the 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.

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.

Notice of proposed rulemaking
(NPRM).
ACTION:
The FAA proposes to adopt a
new airworthiness directive (AD) for all
The Boeing Company Model 737–300,
–400, and –500 series airplanes. This
proposed AD was prompted by a report
that a crack indication consistent with
fatigue cracking was found on the left
nacelle support overwing fitting flange
fastener hole during teardown of a
Model 737–300 series airplane. This
proposed AD would require a general
visual inspection of the strut to wing
diagonal brace at a certain location for
cracking. For certain airplanes, this
proposed AD would also require an
ultrasonic inspection of certain fasteners
of the nacelle support overwing fitting
at a certain location for cracking. For
certain other airplanes, this proposed
AD would also require a magnetic check
of the nacelle support overwing fitting
at a certain location to determine the
material composition. This proposed
AD would also require applicable oncondition actions. The FAA is
proposing this AD to address the unsafe
condition on these products.
SUMMARY:
The FAA must receive comments
on this proposed AD by April 3, 2020.
DATES:
You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2018-06-07, which applies to all The Boeing Company Model 757-200, -
200CB, and -300 series airplanes. AD 2018-06-07 requires inspecting the
fuselage frame at a certain station for existing repairs, repetitive
inspections, and applicable repairs. Since the FAA issued AD 2018-06-
07, the agency has received reports of new crack findings outside of
the AD 2018-06-07 inspection area, which the current inspections will
not detect. This proposed AD would continue to require the actions in
AD 2018-06-07, with an expanded inspection area, additional
inspections, a modified inspection type, and applicable repairs. The
FAA is proposing this AD to address the unsafe condition on these
products.
DATES: The FAA must receive comments on this proposed AD by April 3,
2020.
ADDRESSES: You may send comments, using the procedures found in 14 CFR

Discussion
The FAA issued AD 2018-06-07, Amendment 39-19227 (83 FR 13398,
March 29, 2018) (``AD 2018-06-07''), for all The Boeing Company Model
757-200, -200CB, and -300 series airplanes. AD 2018-06-07 requires
inspecting the fuselage frame at station (STA) 1640 for existing
repairs, repetitive inspections, and applicable repairs. AD 2018-06-07
resulted from a report of fatigue cracking found in a certain fuselage
frame, which severed the inner chord and web. The FAA issued AD 2018-
06-07 to address cracking of the fuselage frame at STA 1640, which
could result in reduced structural integrity of the airplane.
Actions Since AD 2018-06-07 Was Issued
Since the FAA issued AD 2018-06-07, the FAA has received reports of
new crack findings outside of the AD 2018-06-07 inspection area. During
the inspections required by AD 2018-06-07, an operator found the STA
1640 frame with a crack starting from the third fastener below the
stringer S-14 intercostal on the right side. The crack was
approximately 3 inches long and had grown into an insulation stud hole
in the web near the outer chord. The crack was not in the area
inspected as required by AD 2018-06-07. There have also been reports of
cracks found growing out of the fastener holes in the inner chord in
the aft direction, towards the web away from the original inspection
areas. The FAA has therefore determined that the inspection area must
be expanded and new inspections must be added.
Related Service Information Under 1 CFR Part 51
The FAA has reviewed Boeing Alert Service Bulletin 757-53A0108,
Revision 1, dated July 17, 2019. This service information describes
procedures for an inspection of the fuselage frame for existing frame
repairs or replacements, a detailed inspection for any crack, nick, or
gouge in the STA 1640 fuselage frame, repetitive high frequency eddy
current and low frequency eddy current inspections for cracking in the
STA 1640 fuselage frame between stringers S-11 and S-16, and repair.
The FAA has also reviewed Aviation Partners Boeing (APB) Alert
Service Bulletin AP757-53-001, Revision 2, dated October 22, 2019. This
service information provides compliance times for accomplishing the
procedures identified in Boeing Alert Service Bulletin 757-53A0108,
Revision 1, dated July 17, 2019, for airplanes on which APB blended or
scimitar blended winglets are installed.
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 FAA has 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
Although this proposed AD does not explicitly restate the
requirements of AD 2018-06-07, this proposed AD would retain certain
requirements of AD 2018-06-07. Those requirements are referenced in the
service information identified previously, which, in turn, is
referenced in paragraph (g) of this proposed AD. This proposed AD would
expand the inspection area, add inspections, and modify a certain
inspection type.
This proposed AD would also require accomplishment of the actions
identified as ``RC'' (required for compliance) in the Accomplishment
Instructions of Boeing Alert Service Bulletin 757-53A0108, Revision 1,
dated July 17, 2019; and Aviation Partners Boeing (APB) Alert Service
Bulletin AP757-53-001, Revision 2, dated October 22, 2019, described
previously, except for any differences identified as exceptions in the
regulatory text of this proposed AD.
The initial compliance times for the airplanes identified in Boeing
Alert Service Bulletin 757-53A0108, Revision 1, dated July 17, 2019,
range from within 500 flight cycles after the effective date of this
AD, to within 16,000 flight cycles after the installation of the local
frame replacement, depending on the configuration. The repetitive
intervals range from 1,800 flight cycles to 10,400 flight cycles,
depending on the configuration.
The initial compliance times for the airplanes identified in
Aviation Partners Boeing (APB) Alert Service Bulletin AP757-53-001,
Revision 2, dated October 22, 2019, range from within 500 flight cycles
after the effective date of this AD, to within 16,000 flight cycles
after the installation of the local frame replacement, depending on the
configuration. The repetitive intervals range from 1,900 flight cycles
to 8,600 flight cycles, depending on the configuration.
For information on the procedures and compliance times, see Boeing
Alert Service Bulletin 757-53A0108, Revision 1, dated July 17, 2019, at
https://www.regulations.gov by searching for and locating Docket No.
FAA-2020-0094.
Costs of Compliance
The FAA estimates that this proposed AD affects 606 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.

----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable us to
provide cost estimates for the on-condition repair 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.
Regulatory Findings
The FAA has 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 that the 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.
