747–200C, 747–300, 747–400, 747–
400D, and 747SP series airplanes. This
AD was prompted by reports of worn or
incorrectly assembled latches on main
deck escape slides installed on airplane
doors. This AD requires determining if
the latches are correctly assembled; and
doing corrective actions if necessary.
This AD also requires, for certain
airplanes, modifications to the escape
slide/rafts and escape slides. We are
issuing this AD to prevent a latch hook
moving from closed to open in an
escape slide/raft or escape slide, which
could result in the escape slide/raft or
escape slide not deploying correctly in
an emergency, or releasing/inflating into
the passenger cabin and causing injury
to passengers and crew.
DATES: This AD is effective November 6,
2013.
The Director of the Federal Register

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to the specified products. The
NPRM published in the Federal
Register on February 8, 2013 (78 FR
9346). The NPRM proposed to require
determining if the latches on main deck
escape slides installed on airplane doors
are correctly assembled; and doing
corrective actions if necessary. The
NPRM also proposed to require, for
certain airplanes, modifications to the
escape slide/rafts and escape slides.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the proposal (78 FR 9346,
February 8, 2013) and the FAA’s
response to each comment.
Request To Extend Compliance Time
Delta Air Lines (DAL) requested that
the compliance time in the NPRM (78
FR 9346, February 8, 2013) be extended
to 60 months. DAL stated that this will
E:\FR\FM\02OCR1.SGM
02OCR1
Federal Register / Vol. 78, No. 191 / Wednesday, October 2, 2013 / Rules and Regulations
allow for the modification to be
accomplished at the next scheduled
overhaul for DAL’s affected slides.
We disagree with DAL’s request to
extend the compliance time. In
developing an appropriate compliance
time for this action, we considered the
safety implications, parts availability,
and normal maintenance schedules for
the timely accomplishment of the
inspections and modification. However,
under the provisions of paragraph (j) of
this final rule, we will consider requests
for approval of an extension of the
compliance time if sufficient data are
submitted to substantiate that the new
compliance time would provide an
acceptable level of safety. We have not
changed this final rule in this regard.
Requests To Refer to Revised Service
Information
United Airlines and Boeing stated that
Boeing has issued revised service
information. The commenters requested
that the service information in the
NPRM (78 FR 9346, February 8, 2013)
be updated to refer to Boeing Special
Attention Service Bulletin 747–25–
3428, Revision 4, dated February 25,
2013.
DAL requested that the NPRM (78 FR
9346, February 8, 2013) be revised to
allow the replacement of affected slides
with slides on which the inspection and
modification have been done in
accordance with the Accomplishment
Instructions of Boeing Special Attention
Service Bulletin 747–25–3428, Revision
3, dated June 14, 2012.
We agree with United Airlines’ and
Boeing’s requests and have revised
paragraphs (c), (g), and (h) in this final
rule to refer to Boeing Special Attention
60677
replaced with slides that have
completed the inspection and
modification in accordance with the
Accomplishment Instructions of Boeing
Special Attention Service Bulletin 747–
25–3428, Revision 3, dated June 14,
2012. However, once this final rule is
issued, any person may request
approval of an AMOC under the
provisions of paragraph (j) of this final
rule. We have not changed this final
rule in this regard.
Service Bulletin 747–25–3428, Revision
4, dated February 25, 2013.
We also agree with DAL’s request and
have revised paragraph (i) of this final
rule by redesignating paragraph (i) of
the NPRM (78 FR 9346, February 8,
2013) as paragraph (i)(2), and adding
new paragraph (i)(1), which provides
credit for the applicable actions
required by paragraph (g) of this final
rule, if those actions were performed
before the effective date of this final rule
using Boeing Special Attention Service
Bulletin 747–25–3428, Revision 3, dated
June 14, 2012.
Additional Change to This Final Rule
We added Note 1 to paragraph (g) of
this final rule to reference additional
guidance material.
Request To Allow Replacement of
Slides Using a Means Other Than the
Service Information
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 (78 FR 9346,
February 8, 2013) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (78 FR 9346,
February 8, 2013).
We also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this AD.
DAL requested that, alternatively, the
proposed AD (78 FR 9346, February 8,
2013) be revised to include a statement
that accomplishment of the inspection
and modification by means of an
approved routine maintenance item
would be acceptable.
As previously stated, we deem it
acceptable to replace an affected part
with a part that has been inspected and
modified in accordance with the
Accomplishment Instructions of Boeing
Special Attention Service Bulletin 747–
25–3428, Revision 3, dated June 14,
2012.
Regarding the use of an approved
maintenance item instead of the
Accomplishment Instructions of Boeing
Special Attention Service Bulletin 747–
25–3428, Revision 3, dated June 14,
2012, DAL included this as a
conditional statement if the slide
replacement discussed above was
deemed unacceptable. As stated above,
we agree that affected slides can be

Federal Register / Vol. 78, No. 191 / Wednesday, October 2, 2013 / Rules and Regulations
According to the manufacturer, all of
the costs of this AD may be covered
under warranty, thereby reducing the
cost impact on affected individuals. We
do not control warranty coverage for
affected individuals. As a result, we
have included all costs in our cost
estimate.
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
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.

multiple reports of cracks of overwing
frames. This AD requires repetitive
inspections for cracking of the overwing
frames, and corrective actions if
necessary. We are issuing this AD to
detect and correct such cracking that
could sever a frame, which may increase
the loading of adjacent frames, and
result in damage to the adjacent
structure and consequent loss of
structural integrity of the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
We issued an SNPRM (supplemental
notice of proposed rulemaking) to
amend 14 CFR part 39 by adding an
airworthiness directive (AD) that would
apply to the specified products. The
SNPRM published in the Federal
Register on May 6, 2013 (78 FR 26286).
We preceded the SNPRM with a notice
of proposed rulemaking (NPRM) that
published in the Federal Register on
May 9, 2012 (77 FR 27142). The NPRM
(77 FR 27142, May 9, 2012) proposed to
require repetitive inspections for
cracking of the overwing frames, and
corrective actions if necessary. The
SNPRM proposed to revise the initial
compliance time and provide an
optional modification that would extend
the compliance time for the next
repetitive inspection.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the SNPRM (78 FR 26286,
May 6, 2013) and the FAA’s response to
each comment.
Request To Correct Service Bulletin
Title
Boeing noted an error in the title of a
service bulletin referenced in
paragraphs (h) and (h)(2) of the SNPRM
(78 FR 26286, May 6, 2013). Boeing
requested the word ‘‘Alert’’ be removed
with reference to ‘‘Boeing ‘Alert’ Service
Bulletin 717–53–0035, dated June 8,
2012.’’
We agree with Boeing’s request. We
have revised paragraphs (h) and (h)(2) of
this final rule to correct the service
bulletin title accordingly, since the
referenced service bulletin is not an
‘‘Alert’’ service bulletin.
Request To Provide Credit for Previous
Actions
Boeing stated that cracked overwing
frames had been found during
scheduled inspections done in
accordance with 717 Maintenance Task
53–129–01, and that the frames were
replaced as a consequence. Boeing
requested that we revise the SNPRM (78

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B,
747-200C, 747-300, 747-400, 747-400D, and 747SP series airplanes. This
AD was prompted by reports of worn or incorrectly assembled latches on
main deck escape slides installed on airplane doors. This AD requires
determining if the latches are correctly assembled; and doing
corrective actions if necessary. This AD also requires, for certain
airplanes, modifications to the escape slide/rafts and escape slides.
We are issuing this AD to prevent a latch hook moving from closed to
open in an escape slide/raft or escape slide, which could result in the
escape slide/raft or escape slide not deploying correctly in an
emergency, or releasing/inflating into the passenger cabin and causing
injury to passengers and crew.
DATES: This AD is effective November 6, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of November 6,
2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to the specified products. The
NPRM published in the Federal Register on February 8, 2013 (78 FR
9346). The NPRM proposed to require determining if the latches on main
deck escape slides installed on airplane doors are correctly assembled;
and doing corrective actions if necessary. The NPRM also proposed to
require, for certain airplanes, modifications to the escape slide/rafts
and escape slides.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
(78 FR 9346, February 8, 2013) and the FAA's response to each comment.
Request To Extend Compliance Time
Delta Air Lines (DAL) requested that the compliance time in the
NPRM (78 FR 9346, February 8, 2013) be extended to 60 months. DAL
stated that this will
[[Page 60677]]
allow for the modification to be accomplished at the next scheduled
overhaul for DAL's affected slides.
We disagree with DAL's request to extend the compliance time. In
developing an appropriate compliance time for this action, we
considered the safety implications, parts availability, and normal
maintenance schedules for the timely accomplishment of the inspections
and modification. However, under the provisions of paragraph (j) of
this final rule, we will consider requests for approval of an extension
of the compliance time if sufficient data are submitted to substantiate
that the new compliance time would provide an acceptable level of
safety. We have not changed this final rule in this regard.
Requests To Refer to Revised Service Information
United Airlines and Boeing stated that Boeing has issued revised
service information. The commenters requested that the service
information in the NPRM (78 FR 9346, February 8, 2013) be updated to
refer to Boeing Special Attention Service Bulletin 747-25-3428,
Revision 4, dated February 25, 2013.
DAL requested that the NPRM (78 FR 9346, February 8, 2013) be
revised to allow the replacement of affected slides with slides on
which the inspection and modification have been done in accordance with
the Accomplishment Instructions of Boeing Special Attention Service
Bulletin 747-25-3428, Revision 3, dated June 14, 2012.
We agree with United Airlines' and Boeing's requests and have
revised paragraphs (c), (g), and (h) in this final rule to refer to
Boeing Special Attention Service Bulletin 747-25-3428, Revision 4,
dated February 25, 2013.
We also agree with DAL's request and have revised paragraph (i) of
this final rule by redesignating paragraph (i) of the NPRM (78 FR 9346,
February 8, 2013) as paragraph (i)(2), and adding new paragraph (i)(1),
which provides credit for the applicable actions required by paragraph
(g) of this final rule, if those actions were performed before the
effective date of this final rule using Boeing Special Attention
Service Bulletin 747-25-3428, Revision 3, dated June 14, 2012.
Request To Allow Replacement of Slides Using a Means Other Than the
Service Information
DAL requested that, alternatively, the proposed AD (78 FR 9346,
February 8, 2013) be revised to include a statement that accomplishment
of the inspection and modification by means of an approved routine
maintenance item would be acceptable.
As previously stated, we deem it acceptable to replace an affected
part with a part that has been inspected and modified in accordance
with the Accomplishment Instructions of Boeing Special Attention
Service Bulletin 747-25-3428, Revision 3, dated June 14, 2012.
Regarding the use of an approved maintenance item instead of the
Accomplishment Instructions of Boeing Special Attention Service
Bulletin 747-25-3428, Revision 3, dated June 14, 2012, DAL included
this as a conditional statement if the slide replacement discussed
above was deemed unacceptable. As stated above, we agree that affected
slides can be replaced with slides that have completed the inspection
and modification in accordance with the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 747-25-3428, Revision 3,
dated June 14, 2012. However, once this final rule is issued, any
person may request approval of an AMOC under the provisions of
paragraph (j) of this final rule. We have not changed this final rule
in this regard.
Additional Change to This Final Rule
We added Note 1 to paragraph (g) of this final rule to reference
additional guidance material.
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 (78 FR 9346, February 8, 2013) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 9346, February 8, 2013).
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 121 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Determine if latches are 1 work-hour x $85 per $0............... $85.............. $10,285.
correctly assembled. hour = $85.
Option to rework/replace Between 3 and 24 work- $286 per latch... Between $541 and Between $65,461
latches instead of determining hours x $85 per hour $2,326. and $281,446.
if latches are correctly = Between $255 and
assembled. $2,040.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that would be required based on the results of the latch assembly
determination. We have no way of determining the number of aircraft
that might need this replacement:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Corrective action.................. Between 3 and 24 work-hours $286 per latch........ Between $541 and
x $85 per hour = Between $2,326.
$255 and $2,040.
----------------------------------------------------------------------------------------------------------------
[[Page 60678]]
According to the manufacturer, all of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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
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.
