SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 737–8 and 737–9 airplanes. The NPRM published in the Federal Register on April 2, 2021 (86 FR 17324). The NPRM 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. In the NPRM, the FAA proposed to require installing a new FQPU and doing an FQPU software check. 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. Discussion of Final Airworthiness Directive Comments The FAA received comments from Boeing and United Airlines who supported the NPRM without change. 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, 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 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 an FQPU with part number 30128–06 or 30128–58, as applicable, or an FQPU with a later-approved part number, and doing an 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 ADDRESSES. Costs of Compliance The FAA estimates that this AD affects 66 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Installation and software check ...................... 3 work-hour × $85 per 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 AD may be covered under warranty, thereby reducing the cost impact on affected operators. khammond on DSKJM1Z7X2PROD with RULES 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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain The Boeing 
Company Model 737-8 and 737-9 airplanes. The NPRM published in the 
Federal Register on April 2, 2021 (86 FR 17324). The NPRM 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. 
In the NPRM, the FAA proposed to require installing a new FQPU and 
doing an FQPU software check. 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.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from Boeing and United Airlines who 
supported the NPRM without change.

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, 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 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 an FQPU with part number 30128-06 or 30128-58, as 
applicable, or an FQPU with a later-approved part number, and doing an 
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 ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 66 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                         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 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

    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.

Sec.  39.13  [Amended]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2021-12-13 The Boeing Company: Amendment 39-21600; Docket No. FAA-
2021-0017; Project Identifier AD-2020-01186-T.

(a) Effective Date

    This airworthiness directive (AD) is effective July 29, 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.

[[Page 33112]]

(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 
Special Attention Requirements Bulletin 737-28-1363 RB, dated June 
2, 2020, do all applicable actions identified in, and in accordance 
with, the Accomplishment Instructions of Boeing Special Attention 
Requirements Bulletin 737-28-1363 RB, dated June 2, 2020.
    Note 1 to paragraph (g): Guidance for accomplishing the actions 
required by this AD can be found in Boeing Special Attention Service 
Bulletin 737-28-1363, dated June 2, 2020, which is referred to in 
Boeing Special Attention Requirements Bulletin 737-28-1363 RB, dated 
June 2, 2020.

(h) Exception to Service Information Specifications

    Where Boeing Special Attention Requirements Bulletin 737-28-1363 
RB, dated June 2, 2020, uses the phrase ``the Original Issue date of 
Requirements Bulletin 737-28-1363 RB,'' this AD requires using ``the 
effective date of this AD.''

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle ACO Branch, FAA, has the authority to 
approve AMOCs for this AD, if requested using the procedures found

if it is approved by The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Seattle 
ACO Branch, FAA, to make those findings. To be approved, the repair
