SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all The Boeing Company Model
737–100, –200, –200C, –300, –400, and
–500 series airplanes. The NPRM
published in the Federal Register on
June 10, 2019 (84 FR 26778). The NPRM
was prompted by significant changes
made to the AWLs related to fuel tank
ignition prevention and the nitrogen
generation system. The NPRM proposed
to require revising the existing
maintenance or inspection program, as
applicable, to include new or revised
AWLs.
The FAA is issuing this AD to address
the potential of ignition sources inside
fuel tanks, which, in combination with
flammable fuel vapors, could result in
fuel tank explosions and consequent
loss of the airplane.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment.
Support for the NPRM
Air Line Pilots Association,
International (ALPA) agreed with the
intent of the NPRM.

Effect of Winglets on Accomplishment
of the Proposed Actions
Aviation Partners Boeing stated that
the installation of winglets per
Supplemental Type Certificate (STC)
ST01219SE does not affect the
accomplishment of the manufacturer’s
service instructions.
The FAA agrees with the commenter
that STC ST01219SE does not affect the
accomplishment of the manufacturer’s
service instructions. Therefore, the
installation of STC ST01219SE does not
affect the ability to accomplish the
actions required by this AD. The FAA
has not changed this AD in this regard.
VerDate Sep<11>2014

Request for Additional Affected AD
Boeing requested that the FAA
include AD 2018–04–12, Amendment
39–19208 (83 FR 9178, March 5, 2018)
(‘‘AD 2018–04–12’’), as an affected AD
in the proposed AD. Boeing pointed out
that AD 2018–04–12 requires operators
to incorporate certain AWLs included in
certain previous revisions of Boeing
737–100/200/200C/300/400/500
Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs), D6–38278–CMR. Boeing
explained that the specific AWLs
referenced by AD 2018–04–12 are still
present in the latest revision mandated
by this AD, but are at a later revision,
and as such, should be considered
terminating action for the requirements
of paragraph (h) of AD 2018–04–12.
Boeing noted that AD 2013–13–15,
Amendment 39–17503 (78 FR 42415,
July 16, 2013) (‘‘AD 2013–13–15’’), has
similar requirements to those in AD
2018–04–12, and that those similar
requirements in AD 2013–13–15 are
terminated as specified in paragraph
(j)(3) of the proposed AD.
The FAA agrees with the commenter’s
request for the reasons provided. The
FAA has added paragraph (b)(7) to this
AD to specify that AD 2018–04–12 is
affected by this AD, and paragraph (j)(7)
to this AD to specify that the
requirements of paragraph (h) of AD
2018–04–12 are terminated by the
revision required by paragraph (g) of
this AD.
Clarification That Previous Alternative
Methods of Compliance (AMOCs) Are
Not Approved For This AD
The regulatory text of the NPRM did
not include a paragraph specifying that
AMOCs previously approved for the
ADs specified in paragraph (j) of this AD
are approved for the corresponding
requirements of this AD. For clarity, the
FAA has added paragraph (k)(4) to this
AD to specify that AMOCs that were
previously approved for the ADs
specified in paragraph (j) of this AD are
not approved as AMOCs for this AD.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule with the changes described
previously and minor editorial changes.
The FAA has determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

The FAA also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this final rule.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing 737–100/
200/200C/300/400/500 Airworthiness
Limitations (AWLs) and Certification
Maintenance Requirements (CMRs), D6–
38278–CMR, dated March 2019. This
service information describes AWLs that
include airworthiness limitation
instructions (ALI) and critical design
configuration control limitations
(CDCCL) tasks related to fuel tank
ignition prevention and the nitrogen
generation system. 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 381 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this AD:
The FAA has determined that revising
the existing maintenance or inspection
program takes an average of 90 workhours per operator, although the FAA
recognizes that this number may vary
from operator to operator. In the past,
the FAA has estimated that this action
takes 1 work-hour per airplane. Since
operators incorporate maintenance or
inspection program changes for their
affected fleet(s), the FAA has
determined that a per-operator estimate
is more accurate than a per-airplane
estimate. Therefore, the FAA estimates
the total cost per operator to be $7,650
(90 work-hours × $85 per work-hour).
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

16DER1
68328
Federal Register / Vol. 84, No. 241 / Monday, December 16, 2019 / Rules and Regulations
develop on products identified in this
rulemaking action.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to transport category
airplanes and associated appliances to
the Director of the System Oversight
Division.
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.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all The Boeing Company
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The
NPRM published in the Federal Register on June 10, 2019 (84 FR 26778).
The NPRM was prompted by significant changes made to the AWLs related
to fuel tank ignition prevention and the nitrogen generation system.
The NPRM proposed to require revising the existing maintenance or
inspection program, as applicable, to include new or revised AWLs.
The FAA is issuing this AD to address the potential of ignition
sources inside fuel tanks, which, in combination with flammable fuel
vapors, could result in fuel tank explosions and consequent loss of the
airplane.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Support for the NPRM
Air Line Pilots Association, International (ALPA) agreed with the
intent of the NPRM.
Effect of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that the installation of winglets
per Supplemental Type Certificate (STC) ST01219SE does not affect the
accomplishment of the manufacturer's service instructions.
The FAA agrees with the commenter that STC ST01219SE does not
affect the accomplishment of the manufacturer's service instructions.
Therefore, the installation of STC ST01219SE does not affect the
ability to accomplish the actions required by this AD. The FAA has not
changed this AD in this regard.
Request for Additional Affected AD
Boeing requested that the FAA include AD 2018-04-12, Amendment 39-
19208 (83 FR 9178, March 5, 2018) (``AD 2018-04-12''), as an affected
AD in the proposed AD. Boeing pointed out that AD 2018-04-12 requires
operators to incorporate certain AWLs included in certain previous
revisions of Boeing 737-100/200/200C/300/400/500 Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),
D6-38278-CMR. Boeing explained that the specific AWLs referenced by AD
2018-04-12 are still present in the latest revision mandated by this
AD, but are at a later revision, and as such, should be considered
terminating action for the requirements of paragraph (h) of AD 2018-04-
12. Boeing noted that AD 2013-13-15, Amendment 39-17503 (78 FR 42415,
July 16, 2013) (``AD 2013-13-15''), has similar requirements to those
in AD 2018-04-12, and that those similar requirements in AD 2013-13-15
are terminated as specified in paragraph (j)(3) of the proposed AD.
The FAA agrees with the commenter's request for the reasons
provided. The FAA has added paragraph (b)(7) to this AD to specify that
AD 2018-04-12 is affected by this AD, and paragraph (j)(7) to this AD
to specify that the requirements of paragraph (h) of AD 2018-04-12 are
terminated by the revision required by paragraph (g) of this AD.
Clarification That Previous Alternative Methods of Compliance (AMOCs)
Are Not Approved For This AD
The regulatory text of the NPRM did not include a paragraph
specifying that AMOCs previously approved for the ADs specified in
paragraph (j) of this AD are approved for the corresponding
requirements of this AD. For clarity, the FAA has added paragraph
(k)(4) to this AD to specify that AMOCs that were previously approved
for the ADs specified in paragraph (j) of this AD are not approved as
AMOCs for this AD.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule with the changes described previously
and minor editorial changes. The FAA has determined that these minor
changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
The FAA also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing 737-100/200/200C/300/400/500 Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),
D6-38278-CMR, dated March 2019. This service information describes AWLs
that include airworthiness limitation instructions (ALI) and critical
design configuration control limitations (CDCCL) tasks related to fuel
tank ignition prevention and the nitrogen generation system. 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 381 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the FAA recognizes that this number may vary from operator to
operator. In the past, the FAA has estimated that this action takes 1
work-hour per airplane. Since operators incorporate maintenance or
inspection program changes for their affected fleet(s), the FAA has
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the FAA estimates the total cost per
operator to be $7,650 (90 work-hours x $85 per work-hour).
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
[[Page 68328]]
develop on products identified in this rulemaking action.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.
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.
