SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2000–06–13 R1,
Amendment 39–12317 (66 FR 36146,
July 11, 2001), which revised AD 2000–
06–13, Amendment 39–11654 (65 FR
17583, April 4, 2000). AD 2000–06–13
superseded AD 98–25–06, Amendment
39–10931 (63 FR 67769, December 9,
1998). AD 2000–06–13 R1 applied to the
specified products. The NPRM
published in the Federal Register on
December 4, 2012 (77 FR 71723). The
NPRM proposed to continue to require
repetitively inspecting for cracking of
the corners of the door frame and the
cross beams of the aft cargo door; doing
corrective actions if necessary; and
modifying the aft cargo door, which
terminates the repetitive inspections.
The NPRM also proposed to add
airplanes to the applicability, add
inspections and related investigative
and corrective actions, revise certain
inspection types, and reduce a certain
compliance time for modifying the
doors.
tkelley on DSK3SPTVN1PROD with RULES
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the proposal (77 FR 71723,
December 4, 2012) and the FAA’s
response to each comment.
Request To Revise Compliance Time
Boeing requested that we revise
paragraph (o) of the NPRM (77 FR
71723, December 4, 2012), which
specified the compliance time by
referring to paragraph 1.E. of Boeing
Alert Service Bulletin 737–52A1153,
dated July 13, 2011. Boeing requested
that we change this compliance time to
‘‘4,500 door flight cycles after the
effective date of this AD’’ to avoid a
potential conflict with other compliance
times in the NPRM. Boeing explained a
scenario in which an operator could
comply with paragraph (o) of the NPRM
within the required compliance time,
but then be immediately out of
compliance with the proposed
inspection in paragraphs (p) and (q) of
the NPRM.
We partially agree with the request.
As written, the compliance time in
paragraph (o) of the NPRM (77 FR
71723, December 4, 2012) could result
in a compliance conflict with other
requirements of this AD for doors
subject to Boeing Alert Service Bulletin
VerDate Mar<15>2010
17:14 Aug 05, 2013
Jkt 229001
737–52A1079, Revision 7, dated
December 17, 2010. We disagree,
however, with Boeing’s requested
compliance time, which would be
unnecessarily more restrictive on
operators. Also, the referenced doors
that have accumulated fewer than
27,000 total flight cycles should be
provided the same compliance time as
doors subject to Boeing Alert Service
Bulletin 737–52A1153, dated July 13,
2011. We have therefore revised
paragraphs (p) and (q) in this final rule
to change the compliance time to a
threshold of 27,000 total flight cycles on
the door, with a grace period of 4,500
flight cycles. Since paragraph (u)(4) of
the NPRM is therefore no longer
necessary, we have removed that
paragraph from this final rule.
Request To Revise Requirement To
Determine Door Configuration
Southwest Airlines (SWA) requested
that we revise paragraph (o) of the
NPRM (77 FR 71723, December 4, 2012),
which specified to ‘‘Inspect the door to
determine the configuration, in
accordance with the Accomplishment
Instructions of Boeing Alert Service
Bulletin 737–52A1153, dated July 13,
2011.’’ SWA considered that the intent
of this proposed requirement could be
accomplished by records research
instead of a physical inspection. The
commenter noted that the
Accomplishment Instructions of this
service bulletin specify only identifying
the part number of the aft cargo door
assembly, and does not specify a
method of accomplishment.
We agree with the commenter that a
records review is acceptable in lieu of
accomplishing an inspection to
determine the configuration of the door.
We have changed paragraph (o)
accordingly in this final rule.
Request To Refer To Revised Service
Information
All Nippon Airways (ANA) and
Boeing requested that we revise the
NPRM (77 FR 71723, December 4, 2012)
to also refer to Boeing Special Attention
Service Bulletin 737–52–1154, Revision
1, dated August 3, 2011, in all locations
where Boeing Service Bulletin 737–52–
1154, dated December 17, 2010, is cited.
The commenters noted that some
locations of the NPRM referred to only
the original version, but other
paragraphs referred to the original
version ‘‘as revised by Boeing Special
Attention Service Bulletin 737–52–
1154, Revision 1, dated August 3,
2011.’’
We agree with the commenter and
have revised paragraphs (r)(2) and (u)(2)
in this final rule to also add ‘‘as revised

by Boeing Special Attention Service
Bulletin 737–52–1154, Revision 1, dated
August 3, 2011,’’ after the original
service bulletin citation.
Request To Clarify Access Procedures
ANA noted that paragraph (s) of the
NPRM (77 FR 71723, December 4, 2012)
identified certain Parts in the
Accomplishment Instructions of Boeing
Alert Service Bulletin 737–52A1153,
dated July 13, 2011, for compliance with
the proposed requirements. ANA stated
that Part 2, which was not identified in
paragraph (s) of the NPRM, provides
access procedures. ANA questioned
whether the AD required specific
procedures for access.
We agree, and have added new
paragraph (u)(4) in this final rule to
clarify that the access and restoration
procedures specified in the referenced
service information are not required by
this AD.
Request To Clarify Required Part
References for Compliance
ANA noted that paragraph (t) of the
NPRM (77 FR 71723, December 4, 2012)
referred to Parts 1, 3, 4, 7, and 8 of the
Accomplishment Instructions of Boeing
Alert Service Bulletin 737–52A1153,
dated July 13, 2011. Table 3 and Table
4 of that service bulletin also refer to
Parts 5 and 6 of that service bulletin.
ANA questioned whether operators
might do Part 5 and Part 6, which
describe the preventive modification
procedures, if no cracks are found. To
avoid the need for requests for
alternative methods of compliance
(AMOCs) regarding this proposed
requirement, ANA requested that we
revise paragraph (t) of the NPRM to
clarify that compliance is ‘‘in
accordance with Parts 1, 2, 3, 4, 5, 6, 7,
and 8’’ of that service bulletin.
We disagree with the commenter.
Paragraph (s) requires actions in
accordance with Parts 5 and 6 of the
Accomplishment Instructions of Boeing
Alert Service Bulletin 737–52A1153,
dated July 13, 2011. Paragraph (t) of this
AD requires other actions, done in
accordance with Parts 1, 3, 4, 7, and 8
of that service bulletin. We find it
unnecessary to change this AD
regarding this issue.
Request To Exclude Certain
Supplemental Structural Inspections
Paragraph (v) of the NPRM (77 FR
71723, December 4, 2012) would
provide relief from certain supplemental
structural inspections specified in
Boeing Alert Service Bulletin 737–
52A1153, dated July 13, 2011, and
Boeing Alert Service Bulletin 737–
52A1079, Revision 7, dated December

06AUR1
Federal Register / Vol. 78, No. 151 / Tuesday, August 6, 2013 / Rules and Regulations
17, 2010. Boeing requested that we
revise paragraph (v) of the NPRM to also
provide relief from the supplemental
structural inspections specified in Table
5 of paragraph 1.E., ‘‘Compliance,’’ of
Boeing Service Bulletin 737–52–1154,
dated December 17, 2010. Boeing noted
that the NPRM would require inspection
of the adjacent cross beam if cracks are
found in the lower cross beam, and
repair of any cracked adjacent cross
beam, in accordance with Boeing
Service Bulletin 737–52–1154, dated
December 17, 2010, but the damagetolerance inspections associated with
that repair are not mentioned.
We agree with the request. We have
revised paragraph (v) in this final rule
to also include reference to Table 5 of
Boeing Service Bulletin 737–52–1154,
dated December 17, 2010.
service information, if it is available
before the final rule is issued, to reduce
additional burden for Boeing and the
operators. Boeing reported that Boeing
Service Bulletin 737–52–1154 was being
revised to add extra material to the
repair parts to address issues regarding
repair kits found during the validation
of the bulletin.
We disagree to delay issuance of the
final rule pending issuance of revised
service information. Accomplishing the
service information specified in this AD
addresses the identified unsafe
condition. When the revised service
bulletins are presented to us for review,
however, we might consider approving
them as AMOCs for this AD. We have
not changed this final rule regarding
this issue.
Request To Delay Final Rule Pending
Revised Service Information
ANA stated that Boeing was in the
process of revising Boeing Service
Bulletins 737–52–1153 and 737–52–
1154 based on ANA’s validation. ANA
requested that we cite the revised
Additional Changes Made to This AD
We have revised paragraph (v) and
Note 2 to paragraph (v) of this final rule.
We have designated paragraph (v) as
paragraph (v)(1) of this final rule, and
have reidentified Note 2 to paragraph (v)
as paragraph (v)(2) of this final rule.

Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this AD
with the changes described previously—
and minor editorial changes. We have
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM (77 FR
71723, December 4, 2012) for correcting
the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (77 FR 71723,
December 4, 2012).
We also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this AD.

Federal Register / Vol. 78, No. 151 / Tuesday, August 6, 2013 / Rules and Regulations
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.
(b) Affected ADs
This AD supersedes AD 2000–06–13 R1,
Amendment 39–12317 (66 FR 36146, July 11,
2001).
Regulatory Findings
We have determined that 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) Is not a ‘‘significant rule’’ under
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.
(e) Unsafe Condition
This AD was prompted by reports of
cracking in the forward and aft corner frame
of the aft cargo door and in the lower cross
beam. We are issuing this AD to prevent
fatigue cracking of the corners of the door
frame and the cross beams of the aft cargo
door, which could result in rapid
depressurization of the airplane.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding airworthiness directive (AD) 2000-06-13 R1,
which applied to certain The Boeing Company Model 737-200, -200C, -300,
and -400 series airplanes. AD 2000-06-13 R1 required repetitively
inspecting for cracking of the corners of the door frame and the cross
beams of the aft cargo door, and corrective actions if necessary. AD
2000-06-13 R1 also required modifying the aft cargo door, which
terminates the repetitive inspections. This new AD adds airplanes to
the applicability, adds inspections and related investigative and
corrective actions, revises certain inspection types, and reduces a
certain compliance time for modifying the doors. This AD was prompted
by reports of cracking in the forward and aft corner frames of the aft
cargo door and in the lower cross beam. We are issuing this AD to
prevent fatigue cracking of the corners of the door frame and the cross
beams of the aft cargo door, which could result in rapid
depressurization of the airplane.
DATES: This AD is effective September 10, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of September 10,
2013.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of May 9,

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2000-06-13 R1, Amendment 39-12317 (66 FR 36146,
July 11, 2001), which revised AD 2000-06-13, Amendment 39-11654 (65 FR
17583, April 4, 2000). AD 2000-06-13 superseded AD 98-25-06, Amendment
39-10931 (63 FR 67769, December 9, 1998). AD 2000-06-13 R1 applied to
the specified products. The NPRM published in the Federal Register on
December 4, 2012 (77 FR 71723). The NPRM proposed to continue to
require repetitively inspecting for cracking of the corners of the door
frame and the cross beams of the aft cargo door; doing corrective
actions if necessary; and modifying the aft cargo door, which
terminates the repetitive inspections. The NPRM also proposed to add
airplanes to the applicability, add inspections and related
investigative and corrective actions, revise certain inspection types,
and reduce a certain compliance time for modifying the doors.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
(77 FR 71723, December 4, 2012) and the FAA's response to each comment.
Request To Revise Compliance Time
Boeing requested that we revise paragraph (o) of the NPRM (77 FR
71723, December 4, 2012), which specified the compliance time by
referring to paragraph 1.E. of Boeing Alert Service Bulletin 737-
52A1153, dated July 13, 2011. Boeing requested that we change this
compliance time to ``4,500 door flight cycles after the effective date
of this AD'' to avoid a potential conflict with other compliance times
in the NPRM. Boeing explained a scenario in which an operator could
comply with paragraph (o) of the NPRM within the required compliance
time, but then be immediately out of compliance with the proposed
inspection in paragraphs (p) and (q) of the NPRM.
We partially agree with the request. As written, the compliance
time in paragraph (o) of the NPRM (77 FR 71723, December 4, 2012) could
result in a compliance conflict with other requirements of this AD for
doors subject to Boeing Alert Service Bulletin 737-52A1079, Revision 7,
dated December 17, 2010. We disagree, however, with Boeing's requested
compliance time, which would be unnecessarily more restrictive on
operators. Also, the referenced doors that have accumulated fewer than
27,000 total flight cycles should be provided the same compliance time
as doors subject to Boeing Alert Service Bulletin 737-52A1153, dated
July 13, 2011. We have therefore revised paragraphs (p) and (q) in this
final rule to change the compliance time to a threshold of 27,000 total
flight cycles on the door, with a grace period of 4,500 flight cycles.
Since paragraph (u)(4) of the NPRM is therefore no longer necessary, we
have removed that paragraph from this final rule.
Request To Revise Requirement To Determine Door Configuration
Southwest Airlines (SWA) requested that we revise paragraph (o) of
the NPRM (77 FR 71723, December 4, 2012), which specified to ``Inspect
the door to determine the configuration, in accordance with the
Accomplishment Instructions of Boeing Alert Service Bulletin 737-
52A1153, dated July 13, 2011.'' SWA considered that the intent of this
proposed requirement could be accomplished by records research instead
of a physical inspection. The commenter noted that the Accomplishment
Instructions of this service bulletin specify only identifying the part
number of the aft cargo door assembly, and does not specify a method of
accomplishment.
We agree with the commenter that a records review is acceptable in
lieu of accomplishing an inspection to determine the configuration of
the door. We have changed paragraph (o) accordingly in this final rule.
Request To Refer To Revised Service Information
All Nippon Airways (ANA) and Boeing requested that we revise the
NPRM (77 FR 71723, December 4, 2012) to also refer to Boeing Special
Attention Service Bulletin 737-52-1154, Revision 1, dated August 3,
2011, in all locations where Boeing Service Bulletin 737-52-1154, dated
December 17, 2010, is cited. The commenters noted that some locations
of the NPRM referred to only the original version, but other paragraphs
referred to the original version ``as revised by Boeing Special
Attention Service Bulletin 737-52-1154, Revision 1, dated August 3,
2011.''
We agree with the commenter and have revised paragraphs (r)(2) and
(u)(2) in this final rule to also add ``as revised by Boeing Special
Attention Service Bulletin 737-52-1154, Revision 1, dated August 3,
2011,'' after the original service bulletin citation.
Request To Clarify Access Procedures
ANA noted that paragraph (s) of the NPRM (77 FR 71723, December 4,
2012) identified certain Parts in the Accomplishment Instructions of
Boeing Alert Service Bulletin 737-52A1153, dated July 13, 2011, for
compliance with the proposed requirements. ANA stated that Part 2,
which was not identified in paragraph (s) of the NPRM, provides access
procedures. ANA questioned whether the AD required specific procedures
for access.
We agree, and have added new paragraph (u)(4) in this final rule to
clarify that the access and restoration procedures specified in the
referenced service information are not required by this AD.
Request To Clarify Required Part References for Compliance
ANA noted that paragraph (t) of the NPRM (77 FR 71723, December 4,
2012) referred to Parts 1, 3, 4, 7, and 8 of the Accomplishment
Instructions of Boeing Alert Service Bulletin 737-52A1153, dated July
13, 2011. Table 3 and Table 4 of that service bulletin also refer to
Parts 5 and 6 of that service bulletin. ANA questioned whether
operators might do Part 5 and Part 6, which describe the preventive
modification procedures, if no cracks are found. To avoid the need for
requests for alternative methods of compliance (AMOCs) regarding this
proposed requirement, ANA requested that we revise paragraph (t) of the
NPRM to clarify that compliance is ``in accordance with Parts 1, 2, 3,
4, 5, 6, 7, and 8'' of that service bulletin.
We disagree with the commenter. Paragraph (s) requires actions in
accordance with Parts 5 and 6 of the Accomplishment Instructions of
Boeing Alert Service Bulletin 737-52A1153, dated July 13, 2011.
Paragraph (t) of this AD requires other actions, done in accordance
with Parts 1, 3, 4, 7, and 8 of that service bulletin. We find it
unnecessary to change this AD regarding this issue.
Request To Exclude Certain Supplemental Structural Inspections
Paragraph (v) of the NPRM (77 FR 71723, December 4, 2012) would
provide relief from certain supplemental structural inspections
specified in Boeing Alert Service Bulletin 737-52A1153, dated July 13,
2011, and Boeing Alert Service Bulletin 737-52A1079, Revision 7, dated
December
[[Page 47551]]
17, 2010. Boeing requested that we revise paragraph (v) of the NPRM to
also provide relief from the supplemental structural inspections
specified in Table 5 of paragraph 1.E., ``Compliance,'' of Boeing
Service Bulletin 737-52-1154, dated December 17, 2010. Boeing noted
that the NPRM would require inspection of the adjacent cross beam if
cracks are found in the lower cross beam, and repair of any cracked
adjacent cross beam, in accordance with Boeing Service Bulletin 737-52-
1154, dated December 17, 2010, but the damage-tolerance inspections
associated with that repair are not mentioned.
We agree with the request. We have revised paragraph (v) in this
final rule to also include reference to Table 5 of Boeing Service
Bulletin 737-52-1154, dated December 17, 2010.
Request To Delay Final Rule Pending Revised Service Information
ANA stated that Boeing was in the process of revising Boeing
Service Bulletins 737-52-1153 and 737-52-1154 based on ANA's
validation. ANA requested that we cite the revised service information,
if it is available before the final rule is issued, to reduce
additional burden for Boeing and the operators. Boeing reported that
Boeing Service Bulletin 737-52-1154 was being revised to add extra
material to the repair parts to address issues regarding repair kits
found during the validation of the bulletin.
We disagree to delay issuance of the final rule pending issuance of
revised service information. Accomplishing the service information
specified in this AD addresses the identified unsafe condition. When
the revised service bulletins are presented to us for review, however,
we might consider approving them as AMOCs for this AD. We have not
changed this final rule regarding this issue.
Additional Changes Made to This AD
We have revised paragraph (v) and Note 2 to paragraph (v) of this
final rule. We have designated paragraph (v) as paragraph (v)(1) of
this final rule, and have reidentified Note 2 to paragraph (v) as
paragraph (v)(2) of this final rule.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously--and minor editorial
changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR 71723, December 4, 2012) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 71723, December 4, 2012).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Costs of Compliance
We estimate that this AD affects 581 airplanes of U.S. registry. We
estimate 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.
We are issuing this rulemaking under the authority described in
Subtitle VII,
[[Page 47552]]
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 have determined that 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) Is not a ``significant rule'' under 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.
