SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2005–05–18,
Amendment 39–14007 (70 FR 12410,
March 14, 2005) (AD 2005–05–18). AD
2005–05–18 applied to certain The
Boeing Company Model 737–600, –700,
–700C, –800, and –900 series airplanes.
The NPRM published in the Federal
E:\FR\FM\08NOR1.SGM
08NOR1
61680
Federal Register / Vol. 86, No. 213 / Monday, November 8, 2021 / Rules and Regulations
Register on June 30, 2021 (86 FR 34660).
The NPRM was prompted by cracking
found in an inspection area on airplanes
not identified in the applicability of AD
2005–05–18. In the NPRM, the FAA
proposed to continue to require
repetitive inspections for cracking of the
webs of the aft pressure bulkhead at a
certain body station, and corrective
action if necessary. The NPRM also
proposed to require revising the
applicability to include additional
airplanes, and adding an inspection for
existing repairs on the newly added
airplanes. The FAA is issuing this AD
to address fatigue cracks in the webs of
the aft pressure bulkhead, which could
result in rapid decompression of the
airplane.
Discussion of Final Airworthiness
Directive
Comments
The FAA received comments from
United Airlines and Jack Kendrick, who
supported the NPRM without change.
The FAA received additional
comments from two commenters,
including Boeing and Aviation Partners
Boeing. The following presents the
comments received on the NPRM and
the FAA’s response to each comment.
Effects of Winglets on Accomplishment
of the Proposed Actions
Aviation Partners Boeing stated that
the installation of blended or split
scimitar winglets per Supplemental
Type Certificate (STC) ST00830SE does
not affect compliance with the proposed
actions.
The FAA agrees with the commenter
that the installation of winglets per STC
ST00830SE does not affect the
accomplishment of the manufacturer’s
service instructions. Therefore, the
installation of STC ST00830SE does not
affect the ability to accomplish the
actions required by this AD. Operators
of airplanes with these winglets do not
need to request a ‘‘change in product’’
alternative method of compliance
(AMOC) approval as specified in 14 CFR
39.17. The FAA has redesignated
paragraph (c) of the proposed AD as
paragraph (c)(1) of this AD, and added
paragraph (c)(2) to this AD accordingly.
Request To Clarify Service Information
Description
Boeing asked that the FAA clarify the
language describing the inspection
location and reporting requirements in
the ‘‘Related Service Information Under
1 CFR 51’’ paragraph in the preamble of
the proposed AD. Boeing stated that the
language should identify the center
dome apex location, and also specify
reporting of any cracks found.
The FAA agrees with the commenter’s
request to clarify the inspection location
in the ‘‘Related Service Information’’
section, due to the vast number of web
fasteners located around the bulkhead.
The FAA has clarified that language
accordingly.
The FAA does not agree with the
commenter’s request to add reporting
language to that section, because the
manufacturer did not include a
reporting requirement for this particular
cracking condition in the service
information. Therefore, the FAA has not
changed this AD in this regard.
Request To Clarify Language in Actions
Since AD 2005–05–18 Was Issued
Section
Boeing requested that the FAA clarify
the language in the Actions Since AD
2005–05–18 Was Issued section of the
proposed AD. Boeing suggested
changing the sentence that begins
‘‘During the assembly process on line
numbers 1167 through 1755, the
fasteners,’’ as follows: ‘‘Fasteners on
line numbers 1167 through 1755 in the
apex dome region are subjected to
clamp-up stresses from the assembly
process and fatigue cycles during
fuselage pressurization.’’ Boeing stated
that this change is to clarify the meaning
of the language used in the proposed
AD.
The FAA acknowledges the
commenter’s request and agrees the
proposed wording provides clarity.
However, that section is not carried over
into this final rule. Therefore, the FAA
has not changed this AD in this regard.
Conclusion
The FAA reviewed the relevant data,
considered any comments received, and
determined that air safety requires
adopting this AD as proposed. Except
for minor editorial changes, and any
other changes described previously, this
AD is adopted as proposed in the
NPRM. None of the changes will
increase the economic burden on any
operator.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing Alert
Service Bulletin 737–53A1251, Revision
2, dated January 20, 2021. This service
information specifies procedures for a
general visual inspection for existing
repairs, repetitive detailed and high
frequency eddy current (HFEC)
inspections for cracks around the web
center dome apex fasteners, repetitive
low frequency eddy current (LFEC)
inspection for cracks around the hidden
web lap splice fastener locations, and
repair of cracks. 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.
Costs of Compliance
The FAA estimates that this AD
affects 744 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this 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
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.

Amendment 39–21769; Docket No.
FAA–2021–0503; Project Identifier AD–
2021–00163–T.
(a) Effective Date
This airworthiness directive (AD) is
effective December 13, 2021.
(b) Affected ADs
This AD replaces AD 2005–05–18,
Amendment 39–14007 (70 FR 12410, March
14, 2005) (AD 2005–05–18).
(c) Applicability
(1) This AD applies to The Boeing
Company Model 737–600, –700, –700C,
–800, and –900 series airplanes, certificated
in any category, as identified in Boeing Alert
Service Bulletin 737–53A1251, Revision 2,
dated January 20, 2021.
(2) Installation of Supplemental Type
Certificate (STC) ST00830SE does not affect
the ability to accomplish the actions required
by this AD. Therefore, for airplanes on which
STC ST00830SE 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.
The Amendment
(e) Unsafe Condition
This AD was prompted by a report of
cracks found at several of the fastener rows
in the web lap splices at the dome apex of
the aft pressure bulkhead, and the
determination that airplanes not affected by
AD 2005–05–18 are subject to this unsafe
condition. The FAA is issuing this AD to
address fatigue cracks in the webs of the aft
pressure bulkhead, which could result in
rapid decompression of the airplane.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2005-05-
18, which applied to certain The Boeing Company Model 737-600, -700, -
700C, -800, and -900 series airplanes. AD 2005-05-18 required
repetitive inspections for cracking of the webs of the aft pressure
bulkhead at a certain body station, and corrective action if necessary.
This AD was prompted by cracking found in that inspection area on
airplanes not identified in the applicability of AD 2005-05-18. This AD
retains the requirements of AD 2005-05-18, revises the applicability to
include additional airplanes, and adds an inspection for existing
repairs on the newly added airplanes. The FAA is issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective December 13, 2021.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of December 13,
2021.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2005-05-18, Amendment 39-14007 (70 FR
12410, March 14, 2005) (AD 2005-05-18). AD 2005-05-18 applied to
certain The Boeing Company Model 737-600, -700, -700C, -800, and -900
series airplanes. The NPRM published in the Federal
[[Page 61680]]
Register on June 30, 2021 (86 FR 34660). The NPRM was prompted by
cracking found in an inspection area on airplanes not identified in the
applicability of AD 2005-05-18. In the NPRM, the FAA proposed to
continue to require repetitive inspections for cracking of the webs of
the aft pressure bulkhead at a certain body station, and corrective
action if necessary. The NPRM also proposed to require revising the
applicability to include additional airplanes, and adding an inspection
for existing repairs on the newly added airplanes. The FAA is issuing
this AD to address fatigue cracks in the webs of the aft pressure
bulkhead, which could result in rapid decompression of the airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from United Airlines and Jack Kendrick,
who supported the NPRM without change.
The FAA received additional comments from two commenters, including
Boeing and Aviation Partners Boeing. The following presents the
comments received on the NPRM and the FAA's response to each comment.
Effects of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that the installation of blended or
split scimitar winglets per Supplemental Type Certificate (STC)
ST00830SE does not affect compliance with the proposed actions.
The FAA agrees with the commenter that the installation of winglets
per STC ST00830SE does not affect the accomplishment of the
manufacturer's service instructions. Therefore, the installation of STC
ST00830SE does not affect the ability to accomplish the actions
required by this AD. Operators of airplanes with these winglets do not
need to request a ``change in product'' alternative method of
compliance (AMOC) approval as specified in 14 CFR 39.17. The FAA has
redesignated paragraph (c) of the proposed AD as paragraph (c)(1) of
this AD, and added paragraph (c)(2) to this AD accordingly.
Request To Clarify Service Information Description
Boeing asked that the FAA clarify the language describing the
inspection location and reporting requirements in the ``Related Service
Information Under 1 CFR 51'' paragraph in the preamble of the proposed
AD. Boeing stated that the language should identify the center dome
apex location, and also specify reporting of any cracks found.
The FAA agrees with the commenter's request to clarify the
inspection location in the ``Related Service Information'' section, due
to the vast number of web fasteners located around the bulkhead. The
FAA has clarified that language accordingly.
The FAA does not agree with the commenter's request to add
reporting language to that section, because the manufacturer did not
include a reporting requirement for this particular cracking condition
in the service information. Therefore, the FAA has not changed this AD
in this regard.
Request To Clarify Language in Actions Since AD 2005-05-18 Was Issued
Section
Boeing requested that the FAA clarify the language in the Actions
Since AD 2005-05-18 Was Issued section of the proposed AD. Boeing
suggested changing the sentence that begins ``During the assembly
process on line numbers 1167 through 1755, the fasteners,'' as follows:
``Fasteners on line numbers 1167 through 1755 in the apex dome region
are subjected to clamp-up stresses from the assembly process and
fatigue cycles during fuselage pressurization.'' Boeing stated that
this change is to clarify the meaning of the language used in the
proposed AD.
The FAA acknowledges the commenter's request and agrees the
proposed wording provides clarity. However, that section is not carried
over into this final rule. Therefore, the FAA has not changed this AD
in this regard.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Except for minor editorial changes, and any other changes
described previously, this AD is adopted as proposed in the NPRM. None
of the changes will increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Service Bulletin 737-53A1251,
Revision 2, dated January 20, 2021. This service information specifies
procedures for a general visual inspection for existing repairs,
repetitive detailed and high frequency eddy current (HFEC) inspections
for cracks around the web center dome apex fasteners, repetitive low
frequency eddy current (LFEC) inspection for cracks around the hidden
web lap splice fastener locations, and repair of cracks. 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.
Costs of Compliance
The FAA estimates that this AD affects 744 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

The FAA estimates the following costs to do any necessary repairs
that are required based on the results of the inspections. The FAA has
no way of determining the number of aircraft that might need these
repairs:

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
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.
