Airworthiness Directives; The Boeing
Company Airplanes
Federal Aviation
Administration (FAA), DOT.
ACTION: Supplemental notice of
proposed rulemaking (SNPRM);
reopening of comment period.
AGENCY:
We are revising an earlier
proposal to supersede Airworthiness
Directive (AD) 2008–13–12 R1, for
certain The Boeing Company Model
737–100, –200, –200C, –300, –400, and
–500 series airplanes. AD 2008–13–12
R1 requires various repetitive
inspections for cracking of the upperframe-to-side-frame splice of the
fuselage, and other specified and
corrective actions if necessary; and also
provides for an optional preventive
modification, which would terminate
the repetitive inspections. This action
revises the notice of proposed
rulemaking (NPRM) by adding postrepair/post-modification inspections.
We are proposing this SNPRM to detect
and correct fatigue cracking of the
upper-frame-to-side-frame splice of the
fuselage, which could result in reduced
structural integrity of the frame and
adjacent lap joint, causing increased
loading in the fuselage skin, which will
accelerate skin crack growth and result
in decompression of the airplane. Since
these actions impose an additional
burden over that proposed in the NPRM,
we are reopening the comment period to
allow the public the chance to comment
on these proposed changes.
DATES: We must receive comments on
this SNPRM by December 29, 2016.
ADDRESSES: You may send comments,

Discussion
We issued an NPRM to amend 14 CFR
part 39 to supersede AD 2008–13–12 R1,
Amendment 39–15719 (73 FR 67383,
November 14, 2008) (‘‘AD 2008–13–12
R1’’). AD 2008–13–12 R1 applied to
certain The Boeing Company Model
737–100, –200, –200C, –300, –400, and
–500 series airplanes. AD 2008–13–12
R1 requires various repetitive
inspections for cracking of the upperframe-to-side-frame splice of the
fuselage, and other specified and
corrective actions if necessary. AD
2008–13–12 R1 also provides for an
optional preventive modification, which
terminates the repetitive inspections.
AD 2008–13–12 R1 resulted from a
report that the upper frame of the
fuselage was severed between stringers
(S) S–13L and S–14L at station (STA)
747, and the adjacent frame at STA 767
had a 1.3-inch-long crack at the same
stringer location. The NPRM published
in the Federal Register on October 9,
2015 (80 FR 61133) (‘‘The NPRM’’). The
NPRM was prompted by reports of
additional fatigue cracking of the upperframe-to-side-frame splice of the
fuselage, and one report of a severed
frame. The NPRM proposed to add, for
certain airplanes, an inspection to
determine if the existing frame repair
meets all specified requirements, and
for certain other airplanes, a new
modification of the upper-frame-to-sideframe splice, which would terminate the
repetitive inspections. The NPRM also
proposed to reduce certain inspection
thresholds and repetitive intervals.
Actions Since Previous NPRM Was
Issued
Since we issued the NPRM, we have
determined that it is necessary to
require post-repair/post-modification
inspections that were not included in
the NPRM.
Related Service Information Under 1
CFR Part 51
We reviewed Boeing Alert Service
Bulletin 737–53A1261, Revision 1,
dated January 30, 2015. The service
information describes procedures for
various repetitive inspections for
cracking of the upper-frame-to-sideframe splice of the fuselage, a
preventive modification to prevent
WFD, an inspection to determine if the
existing frame repair meets all specified
requirements, and corrective actions.
This service information is reasonably
available because the interested parties

Comments
We gave the public the opportunity to
comment on the NPRM. The following
presents the comments received on the
NPRM and the FAA’s response to each
comment. One commenter supported
the actions specified in the NPRM.
Request To Require Post-Repair/PostModification Inspections
Boeing asked that we change
paragraph (j) of the proposed AD (in the
NPRM) to require the post-repair/postmodification inspections that are not
required in that paragraph. Boeing
stated that the WFD evaluation of the
frame repair/modification specified in
Boeing Alert Service Bulletin 737–
53A1261, Revision 1, dated January 30,
2015, indicated the need for reduced
repetitive inspection intervals from
those provided in Boeing Damage
Tolerance Inspection Data Service
Bulletin 737–00–1006, dated March 12,
2010. Boeing added that since the
inspections specified in Boeing Service
Bulletin 737–00–1006, dated March 12,
2010, are not to be used for the postrepair/post-modification inspections
required by 14 CFR 121.1109(c)(2) or
129.109(c)(2), they should be required
by paragraph (j) of the proposed AD.
We agree with the commenter for the
reasons provided. We have changed
paragraph (j) of this SNPRM to require
that post-repair/post-modification
inspections be done in accordance with
the Accomplishment Instructions of
Boeing Alert Service Bulletin 737–
53A1261, Revision 1, dated January 30,
2015.
Lhorne on DSK30JT082PROD with PROPOSALS
Effect of Winglets on Accomplishment
of the Proposed Actions
Aviation Partners Boeing stated that
accomplishing the Supplemental Type
Certificate (STC) ST01219SE does not
affect the actions specified in the
NPRM.
We agree with the commenter. We
have changed paragraph (c) of this
proposed AD to state that installation of
STC ST01219SE does not affect the
ability to accomplish the actions
required by this final rule. Therefore, for
airplanes on which STC ST01219SE is
installed, a ‘‘change in product’’
alternative methods of compliance
(AMOC) approval request is not
necessary to comply with the
requirements of 14 CFR 39.17.

Request To Clarify That the NPRM
Addresses WFD
Boeing asked that we update the
language in ‘‘Actions Since AD 2008–
13–12 R1, Amendment 39–15719 (73 FR
67383, November 14, 2008) Was Issued’’
section of the NPRM to clarify that this
action is intended to address WFD by
supporting the airplane’s limit of
validity (LOV). Boeing noted that a
recently issued WFD-related AD action
used different language regarding WFD.
Boeing stated that Boeing Alert Service
Bulletin 737–53A1261, Revision 1,
dated January 30, 2015, was released in
support of the requirements of 14 CFR
26.21(b) and (c) and provides additional
service action required to support LOV.
We agree to provide clarification. The
NPRM addressed WFD in several
locations in the preamble. To clarify,
this action is intended to address WFD
by supporting the airplane’s LOV, as
stated by Boeing. However, we have not
updated the language in that section of
the NPRM because that section of the
NPRM is not carried over to this
SNPRM. Therefore, no change to this
SNPRM is necessary in this regard.
Request To Clarify Certain Procedures
in the Related Service Information
Section
Boeing asked that we change the
‘‘Related Service Information under 1
CFR part 51’’ section in the NPRM to
clarify the description of the
modification procedures in the service
information. Boeing asked that the
proposed language ‘‘. . . a new
preventive modification, which would
eliminate the need for the repetitive
inspections’’ be changed to ‘‘. . . a
preventive modification to prevent the
WFD.’’ Boeing stated that Boeing Alert
Service Bulletin 737–53A1261, Revision
1, dated January 30, 2015, retains all
inspections specified in Boeing Alert
Service Bulletin 737–53A1261, dated
January 19, 2006, and mandates the
previously optional preventive
modification to mitigate the WFD
concern.
We agree with the commenter for the
reasons provided. We have clarified the
‘‘Related Service Information under 1
CFR part 51’’ section of this SNPRM
accordingly.
Request To Clarify Reason for
Supersedure
Boeing asked that we clarify in the
SUMMARY section of the NPRM the
events that prompted the proposed
supersedure of AD 2008–13–12 R1.
Boeing stated that instead of two reports
of severed frames, as specified in the
NPRM, there was just one report of a
severed frame.

Sfmt 4702
We agree to provide clarification. We
agree that the commenter’s statement is
accurate. However, we have removed
details relating to the NPRM from the
SUMMARY section of this SNPRM;
therefore, no change is necessary to this
SNPRM in this regard.
Request To Clarify Provisions Related
to Repetitive Actions
Boeing asked that we clarify
paragraph (g)(1)(ii) of the proposed AD
(in the NPRM) to state that the actions
are to be repeated until the preventive
modification in paragraph (k) or the
terminating action in paragraph (l) of
the proposed AD has been
accomplished. Boeing added that this
change is consistent with the provisions
of Boeing Alert Service Bulletin 737–
53A1261, Revision 1, dated January 30,
2015, and the requirements of AD 2008–
13–12 R1.
We agree with the commenter for the
reasons provided. We have clarified
paragraph (g)(1)(ii) of this proposed AD
accordingly.
Request To Clarify Inspection Locations
Boeing asked that we change
paragraph (g)(2)(i) of the proposed AD
(in the NPRM) to clarify that the
inspections are for ‘‘existing frame
repairs,’’ instead of ‘‘frames.’’ Boeing
requested that we change ‘‘frame’’ to
‘‘frame repairs,’’ and ‘‘tied frames’’ to
‘‘existing frame repairs.’’
We agree with the commenter. We
have revised paragraph (g)(2)(i) of this
proposed AD accordingly.
Request To Revise Inspection Type
Boeing asked that we revise
paragraphs (k) and (l) of the proposed
AD (in the NPRM) by changing
‘‘detailed and HFEC inspections’’ to just
‘‘HFEC inspections.’’ Boeing stated that
detailed inspections are not specified
during accomplishment of the
preventive modification in Boeing Alert
Service Bulletin 737–53A1261, Revision
1, dated January 30, 2015.
We agree with the commenter for the
reason provided. We have removed
‘‘detailed’’ inspections from paragraphs
(k) and (l) of this proposed AD.
Request To Change Certain Language in
Paragraph (l)(2) of the Proposed AD
Boeing asked that we change
paragraph (l)(2) of the proposed AD (in
the NPRM), which stated that the repair
would terminate the repetitive
inspections required by paragraph (g)(1)
of this AD. Boeing requested that the
proposed AD instead state that the
repair would terminate not only the
repetitive inspections, but also the
preventive modification required by

14NOP1
Federal Register / Vol. 81, No. 219 / Monday, November 14, 2016 / Proposed Rules
Lhorne on DSK30JT082PROD with PROPOSALS
paragraph (k) of the proposed AD.
Boeing added that Boeing Alert Service
Bulletin 737–53A1261, Revision 1,
dated January 30, 2015, provides a
terminating action provision for the
repetitive inspections and the
preventive modification under the
repair. Boeing stated that
accomplishment of the repair removes
the WFD, and therefore the preventive
modification is not required for repaired
frames.
We agree with the commenter for the
reasons provided. We have clarified the
language in paragraph (l)(2) of this
proposed AD accordingly.
Request To Move Terminating Action in
Paragraph (l)(3) of the Proposed AD to
the Credit Paragraph
Boeing asked that we move the
terminating action specified in
paragraph (l)(3) of the proposed AD (in
the NPRM) into the credit for previous
actions specified in paragraph (m) of the
proposed AD (in the NPRM) for
clarification. Boeing stated that
accomplishment of the repair or
preventive modification, as specified in
Boeing Message M–7200–02–1294,
dated August 20, 2002, is a ‘‘previous
action’’ similar to accomplishment of
the repair or preventive modification
specified in Boeing Alert Service
Bulletin 737–53A1261, dated January
19, 2006. Boeing added that paragraph
(l)(3) of the proposed AD (in the NPRM)
stated that the repair or preventive
modification done before the effective
date of the AD terminates the repetitive
inspection requirements of paragraph
(g)(1) of the proposed AD (in the
NPRM). Boeing also asked that we
revise the proposed AD (in the NPRM)
to state that accomplishment of the
repair or preventive modification in
accordance with Boeing Message M–
7200–02–1294, dated August 20, 2002,
if performed before the effective date of
the AD, would also terminate the
preventive modification required by
paragraph (k) of the proposed AD (in the
NPRM).
We agree to revise paragraph (l)(3) of
this proposed AD to state that a repair
or preventive modification done in
accordance with Boeing Message M–
7200–02–1294, dated August 20, 2002,
is acceptable for terminating both the
inspections and the preventive
modification requirements in
paragraphs (g)(1) and (k) of this
proposed AD respectively. We have
changed paragraph (l)(3) of this
proposed AD accordingly.
We do not agree to move paragraph
(l)(3) of the proposed AD (in the NPRM)
into the credit for previous actions
VerDate Sep<11>2014
15:04 Nov 10, 2016
Jkt 241001
specified in paragraph (m) of this
proposed AD. Paragraph (m) of this
proposed AD is intended to give credit
for actions accomplished using previous
revisions of service information for
accomplishing corresponding actions
prior to the effective date of the AD; it
does not terminate any actions and does
not address future actions.
Request To Provide Credit for Certain
Repairs
Boeing asked that we change
paragraph (m) of the proposed AD (in
the NPRM) to provide credit for repairs
that were accomplished before the
effective date of the AD, in accordance
with Boeing Alert Service Bulletin 737–
53A1261, dated January 19, 2006.
Boeing stated that the repair procedures
are the same as those in Boeing Alert
Service Bulletin 737–53A1261, Revision
1, dated January 30, 2015 (as specified
in paragraph (l)(2) of the proposed AD
(in the NPRM)).
We agree with the commenter for the
reason provided. We have added a new
paragraph (m)(3) to this proposed AD to
give credit for repairs specified in
paragraph (l)(2) of the this proposed AD
that are accomplished before the
effective date of this proposed AD.
Request To Remove Repairs as
Terminating Action Under Certain
Conditions
Boeing asked that we change
paragraph (l)(4) of the proposed AD (in
the NPRM) to remove repairs as
acceptable terminating action. Boeing
stated that paragraph (l)(4) of the
proposed AD (in the NPRM) would
provide a terminating action provision
for the repetitive inspections required
by paragraph (g)(2) of the proposed AD
(in the NPRM) if a repair or preventive
modification is accomplished that is
different from the one provided in
Boeing Alert Service Bulletin 737–
53A1261, Revision 1, dated January 30,
2015, provided it has been approved by
the Manager, Los Angeles Aircraft
Certification Office. Boeing added that
there have been repairs performed in the
past that involve trimming the
production upper frame web near S–11
and replacing it with an identical
replacement frame web without
additional reinforcement similar to the
preventive modification or repair.
Boeing noted that the repair is
structurally acceptable; however, it does
not sufficiently reinforce the frame to
provide terminating action for the
inspections, and would require further
service actions, including inspections
and a preventive modification. Boeing
added that the additional inspection
PO 00000
Frm 00004
Fmt 4702

79397
requirements should be specified in the
AMOC approval, and noted that a
preventive modification would not
necessarily be required since prior
approvals would not have taken the
WFD requirements into account.
We agree with the commenter for the
reasons provided. All previously
installed repairs or modifications
installed in accordance with Boeing
Alert Service Bulletin 737–53A1261,
dated January 19, 2006, must be
reevaluated or replaced to ensure that
all WFD requirements are met.
Therefore, we have removed paragraph
(l)(4) of the proposed AD (in the NPRM)
from this proposed AD.
FAA’s Determination
We are proposing this SNPRM
because we 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. Certain changes
described above expand the scope of the
NPRM. As a result, we have determined
that it is necessary to reopen the
comment period to provide additional
opportunity for the public to comment
on this SNPRM.
Proposed Requirements of This SNPRM
This SNPRM would require
accomplishing the actions specified in
the service information described
previously, except as discussed under
‘‘Difference Between this AD and the
Service Information.’’ Refer to this
service information for information on
the procedures and compliance times.
Difference Between This SNPRM and
the Service Information
Boeing Alert Service Bulletin 737–
53A1261, Revision 1, dated January 30,
2015, specifies to contact the
manufacturer for certain repair
instructions, but this proposed AD
would require 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 391 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

susceptibility to widespread fatigue damage
(WFD). We are issuing this AD to detect and
correct fatigue cracking of the upper-frameto-side-frame splice of the fuselage, which
could result in reduced structural integrity of
the frame and adjacent lap joint, causing
increased loading in the fuselage skin, which
will accelerate skin crack growth and result
in decompression of the airplane.

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

SUPPLEMENTARY INFORMATION:
[Docket No. FDA–2008–N–0622]
I. Background
Withdrawal of Two Proposed Rules
In 1990, FDA began a process of
periodically conducting comprehensive
reviews of its regulation process,
including reviewing the backlog of
notices of proposed rulemakings that
were never finalized. As FDA removed
many proposed rules that had not been
finalized, the Agency was able to clean
out the backlog and implement a
process of reviewing these proposed
rules every 5 years. In the Federal
Register of December 12, 2008 (73 FR
75625), FDA withdrew four proposed
rules that were more than 5 years old
that it did not intend to finalize.
Recently, FDA has conducted a
review of proposed rules that are more
than 5 years old, and is announcing the
withdrawal the following two proposed
rules:
DEPARTMENT OF HEALTH AND
HUMAN SERVICES
Food and Drug Administration
AGENCY:
Food and Drug Administration,
HHS.
ACTION:
Notice of withdrawal.
The Food and Drug
Administration (FDA) is announcing the
withdrawal of two proposed rules that
published in the Federal Register more
than 5 years ago. These proposed rules
are no longer considered viable
candidates for final action. FDA is
taking this action because these
proposed rules are out of date.
DATES: The proposed rules are
withdrawn on November 14, 2016.

FDA has reconsidered our position on this issue
and deemed our concerns from 2001 outdated.
We will continue to assess whether rulemaking
in this area is necessary, and if so, we will proceed with a new proposed rule.
This proposed rule is obsolete because FDA has
created a new process that allows for routine
updates to the seafood names without going
through notice and comment rulemaking. See
FDA’s Guide to Acceptable Market Names for
Seafood Sold in Interstate Commerce.
The withdrawal of these proposals
identified in this document does not
preclude the Agency from reinstituting
rulemaking concerning the issues
addressed in the proposals listed in the
chart. Should we decide to undertake
such rulemakings in the future, we will
re-propose the actions and provide new
opportunities for comment.
Furthermore, this notice is only
intended to address the specific actions
identified in this document, and not any
other pending proposals that the Agency
has issued or is considering. The
Agency notes that withdrawal of a
proposal does not necessarily mean that
the preamble statement of the proposal
no longer reflects the current position of
FDA on the matter addressed. You may
wish to review the Agency’s Web site

guidance on the matter.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening
of comment period.
-----------------------------------------------------------------------
SUMMARY: We are revising an earlier proposal to supersede Airworthiness
Directive (AD) 2008-13-12 R1, for certain The Boeing Company Model 737-
100, -200, -200C, -300, -400, and -500 series airplanes. AD 2008-13-12
R1 requires various repetitive inspections for cracking of the upper-
frame-to-side-frame splice of the fuselage, and other specified and
corrective actions if necessary; and also provides for an optional
preventive modification, which would terminate the repetitive
inspections. This action revises the notice of proposed rulemaking
(NPRM) by adding post-repair/post-modification inspections. We are
proposing this SNPRM to detect and correct fatigue cracking of the
upper-frame-to-side-frame splice of the fuselage, which could result in
reduced structural integrity of the frame and adjacent lap joint,
causing increased loading in the fuselage skin, which will accelerate
skin crack growth and result in decompression of the airplane. Since
these actions impose an additional burden over that proposed in the
NPRM, we are reopening the comment period to allow the public the
chance to comment on these proposed changes.
DATES: We must receive comments on this SNPRM by December 29, 2016.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
We issued an NPRM to amend 14 CFR part 39 to supersede AD 2008-13-
12 R1, Amendment 39-15719 (73 FR 67383, November 14, 2008) (``AD 2008-
13-12 R1''). AD 2008-13-12 R1 applied to certain The Boeing Company
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD
2008-13-12 R1 requires various repetitive inspections for cracking of
the upper-frame-to-side-frame splice of the fuselage, and other
specified and corrective actions if necessary. AD 2008-13-12 R1 also
provides for an optional preventive modification, which terminates the
repetitive inspections. AD 2008-13-12 R1 resulted from a report that
the upper frame of the fuselage was severed between stringers (S) S-13L
and S-14L at station (STA) 747, and the adjacent frame at STA 767 had a
1.3-inch-long crack at the same stringer location. The NPRM published
in the Federal Register on October 9, 2015 (80 FR 61133) (``The
NPRM''). The NPRM was prompted by reports of additional fatigue
cracking of the upper-frame-to-side-frame splice of the fuselage, and
one report of a severed frame. The NPRM proposed to add, for certain
airplanes, an inspection to determine if the existing frame repair
meets all specified requirements, and for certain other airplanes, a
new modification of the upper-frame-to-side-frame splice, which would
terminate the repetitive inspections. The NPRM also proposed to reduce
certain inspection thresholds and repetitive intervals.
Actions Since Previous NPRM Was Issued
Since we issued the NPRM, we have determined that it is necessary
to require post-repair/post-modification inspections that were not
included in the NPRM.
Related Service Information Under 1 CFR Part 51
We reviewed Boeing Alert Service Bulletin 737-53A1261, Revision 1,
dated January 30, 2015. The service information describes procedures
for various repetitive inspections for cracking of the upper-frame-to-
side-frame splice of the fuselage, a preventive modification to prevent
WFD, an inspection to determine if the existing frame repair meets all
specified requirements, and corrective actions. This service
information is reasonably available because the interested parties
[[Page 79396]]
have access to it through their normal course of business or by the
means identified in the ADDRESSES section.
Comments
We gave the public the opportunity to comment on the NPRM. The
following presents the comments received on the NPRM and the FAA's
response to each comment. One commenter supported the actions specified
in the NPRM.
Request To Require Post-Repair/Post-Modification Inspections
Boeing asked that we change paragraph (j) of the proposed AD (in
the NPRM) to require the post-repair/post-modification inspections that
are not required in that paragraph. Boeing stated that the WFD
evaluation of the frame repair/modification specified in Boeing Alert
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015,
indicated the need for reduced repetitive inspection intervals from
those provided in Boeing Damage Tolerance Inspection Data Service
Bulletin 737-00-1006, dated March 12, 2010. Boeing added that since the
inspections specified in Boeing Service Bulletin 737-00-1006, dated
March 12, 2010, are not to be used for the post-repair/post-
modification inspections required by 14 CFR 121.1109(c)(2) or
129.109(c)(2), they should be required by paragraph (j) of the proposed
AD.
We agree with the commenter for the reasons provided. We have
changed paragraph (j) of this SNPRM to require that post-repair/post-
modification inspections be done in accordance with the Accomplishment
Instructions of Boeing Alert Service Bulletin 737-53A1261, Revision 1,
dated January 30, 2015.
Effect of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that accomplishing the Supplemental
Type Certificate (STC) ST01219SE does not affect the actions specified
in the NPRM.
We agree with the commenter. We have changed paragraph (c) of this
proposed AD to state that installation of STC ST01219SE does not affect
the ability to accomplish the actions required by this final rule.
Therefore, for airplanes on which STC ST01219SE is installed, a
``change in product'' alternative methods of compliance (AMOC) approval
request is not necessary to comply with the requirements of 14 CFR
39.17.
Request To Clarify That the NPRM Addresses WFD
Boeing asked that we update the language in ``Actions Since AD
2008-13-12 R1, Amendment 39-15719 (73 FR 67383, November 14, 2008) Was
Issued'' section of the NPRM to clarify that this action is intended to
address WFD by supporting the airplane's limit of validity (LOV).
Boeing noted that a recently issued WFD-related AD action used
different language regarding WFD. Boeing stated that Boeing Alert
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015, was
released in support of the requirements of 14 CFR 26.21(b) and (c) and
provides additional service action required to support LOV.
We agree to provide clarification. The NPRM addressed WFD in
several locations in the preamble. To clarify, this action is intended
to address WFD by supporting the airplane's LOV, as stated by Boeing.
However, we have not updated the language in that section of the NPRM
because that section of the NPRM is not carried over to this SNPRM.
Therefore, no change to this SNPRM is necessary in this regard.
Request To Clarify Certain Procedures in the Related Service
Information Section
Boeing asked that we change the ``Related Service Information under
1 CFR part 51'' section in the NPRM to clarify the description of the
modification procedures in the service information. Boeing asked that
the proposed language ``. . . a new preventive modification, which
would eliminate the need for the repetitive inspections'' be changed to
``. . . a preventive modification to prevent the WFD.'' Boeing stated
that Boeing Alert Service Bulletin 737-53A1261, Revision 1, dated
January 30, 2015, retains all inspections specified in Boeing Alert
Service Bulletin 737-53A1261, dated January 19, 2006, and mandates the
previously optional preventive modification to mitigate the WFD
concern.
We agree with the commenter for the reasons provided. We have
clarified the ``Related Service Information under 1 CFR part 51''
section of this SNPRM accordingly.
Request To Clarify Reason for Supersedure
Boeing asked that we clarify in the SUMMARY section of the NPRM the
events that prompted the proposed supersedure of AD 2008-13-12 R1.
Boeing stated that instead of two reports of severed frames, as
specified in the NPRM, there was just one report of a severed frame.
We agree to provide clarification. We agree that the commenter's
statement is accurate. However, we have removed details relating to the
NPRM from the SUMMARY section of this SNPRM; therefore, no change is
necessary to this SNPRM in this regard.
Request To Clarify Provisions Related to Repetitive Actions
Boeing asked that we clarify paragraph (g)(1)(ii) of the proposed
AD (in the NPRM) to state that the actions are to be repeated until the
preventive modification in paragraph (k) or the terminating action in
paragraph (l) of the proposed AD has been accomplished. Boeing added
that this change is consistent with the provisions of Boeing Alert
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015, and
the requirements of AD 2008-13-12 R1.
We agree with the commenter for the reasons provided. We have
clarified paragraph (g)(1)(ii) of this proposed AD accordingly.
Request To Clarify Inspection Locations
Boeing asked that we change paragraph (g)(2)(i) of the proposed AD
(in the NPRM) to clarify that the inspections are for ``existing frame
repairs,'' instead of ``frames.'' Boeing requested that we change
``frame'' to ``frame repairs,'' and ``tied frames'' to ``existing frame
repairs.''
We agree with the commenter. We have revised paragraph (g)(2)(i) of
this proposed AD accordingly.
Request To Revise Inspection Type
Boeing asked that we revise paragraphs (k) and (l) of the proposed
AD (in the NPRM) by changing ``detailed and HFEC inspections'' to just
``HFEC inspections.'' Boeing stated that detailed inspections are not
specified during accomplishment of the preventive modification in
Boeing Alert Service Bulletin 737-53A1261, Revision 1, dated January
30, 2015.
We agree with the commenter for the reason provided. We have
removed ``detailed'' inspections from paragraphs (k) and (l) of this
proposed AD.
Request To Change Certain Language in Paragraph (l)(2) of the Proposed
AD
Boeing asked that we change paragraph (l)(2) of the proposed AD (in
the NPRM), which stated that the repair would terminate the repetitive
inspections required by paragraph (g)(1) of this AD. Boeing requested
that the proposed AD instead state that the repair would terminate not
only the repetitive inspections, but also the preventive modification
required by
[[Page 79397]]
paragraph (k) of the proposed AD. Boeing added that Boeing Alert
Service Bulletin 737-53A1261, Revision 1, dated January 30, 2015,
provides a terminating action provision for the repetitive inspections
and the preventive modification under the repair. Boeing stated that
accomplishment of the repair removes the WFD, and therefore the
preventive modification is not required for repaired frames.
We agree with the commenter for the reasons provided. We have
clarified the language in paragraph (l)(2) of this proposed AD
accordingly.
Request To Move Terminating Action in Paragraph (l)(3) of the Proposed
AD to the Credit Paragraph
Boeing asked that we move the terminating action specified in
paragraph (l)(3) of the proposed AD (in the NPRM) into the credit for
previous actions specified in paragraph (m) of the proposed AD (in the
NPRM) for clarification. Boeing stated that accomplishment of the
repair or preventive modification, as specified in Boeing Message M-
7200-02-1294, dated August 20, 2002, is a ``previous action'' similar
to accomplishment of the repair or preventive modification specified in
Boeing Alert Service Bulletin 737-53A1261, dated January 19, 2006.
Boeing added that paragraph (l)(3) of the proposed AD (in the NPRM)
stated that the repair or preventive modification done before the
effective date of the AD terminates the repetitive inspection
requirements of paragraph (g)(1) of the proposed AD (in the NPRM).
Boeing also asked that we revise the proposed AD (in the NPRM) to state
that accomplishment of the repair or preventive modification in
accordance with Boeing Message M-7200-02-1294, dated August 20, 2002,
if performed before the effective date of the AD, would also terminate
the preventive modification required by paragraph (k) of the proposed
AD (in the NPRM).
We agree to revise paragraph (l)(3) of this proposed AD to state
that a repair or preventive modification done in accordance with Boeing
Message M-7200-02-1294, dated August 20, 2002, is acceptable for
terminating both the inspections and the preventive modification
requirements in paragraphs (g)(1) and (k) of this proposed AD
respectively. We have changed paragraph (l)(3) of this proposed AD
accordingly.
We do not agree to move paragraph (l)(3) of the proposed AD (in the
NPRM) into the credit for previous actions specified in paragraph (m)
of this proposed AD. Paragraph (m) of this proposed AD is intended to
give credit for actions accomplished using previous revisions of
service information for accomplishing corresponding actions prior to
the effective date of the AD; it does not terminate any actions and
does not address future actions.
Request To Provide Credit for Certain Repairs
Boeing asked that we change paragraph (m) of the proposed AD (in
the NPRM) to provide credit for repairs that were accomplished before
the effective date of the AD, in accordance with Boeing Alert Service
Bulletin 737-53A1261, dated January 19, 2006. Boeing stated that the
repair procedures are the same as those in Boeing Alert Service
Bulletin 737-53A1261, Revision 1, dated January 30, 2015 (as specified
in paragraph (l)(2) of the proposed AD (in the NPRM)).
We agree with the commenter for the reason provided. We have added
a new paragraph (m)(3) to this proposed AD to give credit for repairs
specified in paragraph (l)(2) of the this proposed AD that are
accomplished before the effective date of this proposed AD.
Request To Remove Repairs as Terminating Action Under Certain
Conditions
Boeing asked that we change paragraph (l)(4) of the proposed AD (in
the NPRM) to remove repairs as acceptable terminating action. Boeing
stated that paragraph (l)(4) of the proposed AD (in the NPRM) would
provide a terminating action provision for the repetitive inspections
required by paragraph (g)(2) of the proposed AD (in the NPRM) if a
repair or preventive modification is accomplished that is different
from the one provided in Boeing Alert Service Bulletin 737-53A1261,
Revision 1, dated January 30, 2015, provided it has been approved by
the Manager, Los Angeles Aircraft Certification Office. Boeing added
that there have been repairs performed in the past that involve
trimming the production upper frame web near S-11 and replacing it with
an identical replacement frame web without additional reinforcement
similar to the preventive modification or repair. Boeing noted that the
repair is structurally acceptable; however, it does not sufficiently
reinforce the frame to provide terminating action for the inspections,
and would require further service actions, including inspections and a
preventive modification. Boeing added that the additional inspection
requirements should be specified in the AMOC approval, and noted that a
preventive modification would not necessarily be required since prior
approvals would not have taken the WFD requirements into account.
We agree with the commenter for the reasons provided. All
previously installed repairs or modifications installed in accordance
with Boeing Alert Service Bulletin 737-53A1261, dated January 19, 2006,
must be reevaluated or replaced to ensure that all WFD requirements are
met. Therefore, we have removed paragraph (l)(4) of the proposed AD (in
the NPRM) from this proposed AD.
FAA's Determination
We are proposing this SNPRM because we 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.
Certain changes described above expand the scope of the NPRM. As a
result, we have determined that it is necessary to reopen the comment
period to provide additional opportunity for the public to comment on
this SNPRM.
Proposed Requirements of This SNPRM
This SNPRM would require accomplishing the actions specified in the
service information described previously, except as discussed under
``Difference Between this AD and the Service Information.'' Refer to
this service information for information on the procedures and
compliance times.
Difference Between This SNPRM and the Service Information
Boeing Alert Service Bulletin 737-53A1261, Revision 1, dated
January 30, 2015, specifies to contact the manufacturer for certain
repair instructions, but this proposed AD would require 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 391 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

\1\ We currently have no specific cost estimates associated with the parts necessary for the proposed
modification.
We have received no definitive data that would enable us to provide
a cost estimate 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.
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.
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 removing Airworthiness Directive (AD)
2008-13-12 R1, Amendment 39-15719 (73 FR 67383, November 14, 2008), and
adding the following new AD.
The Boeing Company: Docket No. FAA-2015-3984; Directorate Identifier
2015-NM-033-AD.
(a) Comments Due Date
We must receive comments by December 29, 2016.
(b) Affected ADs
This AD replaces AD 2008-13-12 R1, Amendment 39-15719 (73 FR
67383, November 14, 2008) (``AD 2008-13-12 R1'').
(c) Applicability
(1) This AD applies to The Boeing Company Model 737-100, -200, -
200C, -300, -400, and -500 series airplanes, certificated in any
category, as identified in Boeing Alert Service Bulletin 737-
53A1261, Revision 1, dated January 30, 2015.
(2) Installation of Supplemental Type Certificate (STC)
ST01219SE (https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/BE866B732F6CF31086257B9700692796?OpenDocument&Highlight=st01219se)
does not affect the ability to accomplish the actions required by
this AD. Therefore, for airplanes on which STC ST01219SE is
installed, a ''change in product'' alternative method of compliance
(AMOC) approval request is not necessary to comply with the
requirements of 14 CFR 39.17.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by reports of additional fatigue cracking
of the upper-frame-to-side-frame splice of the fuselage, and one
report of a severed frame due to susceptibility to widespread
fatigue damage (WFD). We are issuing this AD to detect and correct
fatigue cracking of the upper-frame-to-side-frame splice of the
fuselage, which could result in reduced structural integrity of the
frame and adjacent lap joint, causing increased loading in the
fuselage skin, which will accelerate skin crack growth and result in
decompression of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
