ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain The Boeing Company Model
737–8 and 737–9 airplanes. This
proposed AD was prompted by a report
that during refueling of the right main
tank, if there is a failure of the automatic
shutoff system, the refueling panel does
not provide the required indication that
the automatic shutoff has failed. This
proposed AD would require installing a
new fuel quantity processor unit (FQPU)
and doing a FQPU software check. The
FAA is proposing this AD to address the
unsafe condition on these products.
DATES: The FAA must receive comments
on this proposed AD by May 17, 2021.

Under the Freedom of Information Act
(FOIA) (5 U.S.C. 552), CBI is exempt
from public disclosure. If your
comments responsive to this NPRM
contain commercial or financial
information that is customarily treated
as private, that you actually treat as
private, and that is relevant or
responsive to this NPRM, it is important
that you clearly designate the submitted
comments as CBI. Please mark each
page of your submission containing CBI
as ‘‘PROPIN.’’ The FAA will treat such
marked submissions as confidential
under the FOIA, and they will not be
placed in the public docket of this
NPRM. Submissions containing CBI
should be sent to Chris Baker,
Aerospace Engineer, Propulsion
Section, FAA, Seattle ACO Branch, 2200
South 216th St., Des Moines, WA 98198;
Background
During refueling, the automatic
shutoff system is supposed to close the
refuel valve when the fuel tank is full.
If the automatic shutoff system fails, the
refuel indicator on the refuel panel
should flash to indicate the failure and
alert the person refueling the airplane.
The FAA has received a report
indicating that on The Boeing Company
Model 737–8 and 737–9 airplanes,
during refueling of the right main tank,
if there is a failure of the automatic
shutoff system, the refueling panel does
not provide the required flashing
indication to the person fueling the
airplane that the automatic shutoff has
failed to shut off the fuel. This is a result
of the flashing threshold in the FQPU
not being set at the correct fuel level.
This condition, if not addressed, could
result in overfill of the right main fuel
tank, spilled fuel, and pooling on the
ground that could come in contact with
an ignition source, resulting in a ground
fire.
Related Service Information Under 1
CFR part 51
The FAA reviewed Boeing Special
Attention Requirements Bulletin 737–
28–1363 RB, dated June 2, 2020. The
service information specifies procedures
for replacing the FQPU having an
17325
incorrect indication threshold with a
FQPU with part number 30128–06 or
30128–58, as applicable, or a FQPU
with a later-approved part number, and
doing a FQPU software check.
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.
FAA’s Determination
The FAA is issuing this NPRM after
determining the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would require
accomplishing the actions identified in
Boeing Special Attention Requirements
Bulletin 737–28–1363 RB, dated June 2,
2020, described previously, except for
any differences identified as exceptions
in the regulatory text of this proposed
AD.
For information on the procedures
and compliance times, see this service
information at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2021–
0017.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affects 66
airplanes of U.S. registry. The FAA
estimates the following costs to comply
with this proposed AD:
ESTIMATED COSTS FOR REQUIRED ACTIONS
Action
Labor cost
Parts cost
Cost per
product
Cost on U.S.
operators
Installation and software check ......................
3 work-hour × $85 per hour = $255 ...............
$0
$255
$16,830
The FAA has included all known
costs in this cost estimate. According to
the manufacturer, however, some or all
of the costs of this proposed AD may be
covered under warranty, thereby
reducing the cost impact on affected
operators.

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
VerDate Sep<11>2014
17:07 Apr 01, 2021
Jkt 253001
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
The FAA determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would not
PO 00000
Frm 00004

Sfmt 4702
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) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

does not provide the required flashing indication to the person fueling
the airplane that the automatic shutoff has failed to shut off the
fuel. This is a result of the flashing threshold in the FQPU not being
set at the correct fuel level. This condition, if not addressed, could
result in overfill of the right main fuel tank, spilled fuel, and
pooling on the ground that could come in contact with an ignition
source, resulting in a ground fire.
Related Service Information Under 1 CFR part 51
The FAA reviewed Boeing Special Attention Requirements Bulletin
737-28-1363 RB, dated June 2, 2020. The service information specifies
procedures for replacing the FQPU having an incorrect indication
threshold with a FQPU with part number 30128-06 or 30128-58, as
applicable, or a FQPU with a later-approved part number, and doing a
FQPU software check.
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.
FAA's Determination
The FAA is issuing this NPRM after determining the unsafe condition
described previously is likely to exist or develop in other products of
the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions identified
in Boeing Special Attention Requirements Bulletin 737-28-1363 RB, dated
June 2, 2020, described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
For information on the procedures and compliance times, see this
service information at https://www.regulations.gov by searching for and
locating Docket No. FAA-2021-0017.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affects 66 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Installation and software check..... 3 work-hour x $85 per $0 $255 $16,830
hour = $255.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in this cost estimate.
According to the manufacturer, however, some or all of the costs of
this proposed AD may be covered under warranty, thereby reducing the
cost impact on affected operators.
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
The FAA 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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

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 adding the following new airworthiness
directive:
The Boeing Company: Docket No. FAA-2021-0017; Project Identifier AD-
2020-01186-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by May 17, 2021.
(b) Affected ADs
None.
(c) Applicability
This AD applies to The Boeing Company Model 737-8 and 737-9
airplanes, certificated in any category, as identified in Boeing
Special Attention Requirements Bulletin 737-28-1363 RB, dated June
2, 2020.
(d) Subject
Air Transport Association (ATA) of America Code 28, Fuel.
(e) Unsafe Condition
This AD was prompted by a report that during refueling of the
right main tank, if there is a failure of the automatic shutoff
system, the refueling panel does not provide the required flashing
indication that the automatic shutoff has failed to shut off the
fuel. The FAA is issuing this AD to address this indication failure
to warn the person fueling the airplane, which could cause overfill
of the right main tank, spilled fuel, and pooling on the ground that
could come in contact with an ignition source, resulting in a ground
fire.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
Except as specified by paragraph (h) of this AD, at the
applicable times specified in the ``Compliance'' paragraph of Boeing
