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 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 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.

Airworthiness Directives; The Boeing 
Company Airplanes 
AGENCY : Federal Aviation 
Administration (FAA), DOT. ACTION : Final rule. 
SUMMARY : The FAA is superseding 
Airworthiness Directive (AD) 2016–25– 29, which applied to certain The Boeing Company Model 767–200 and –300 series airplanes. AD 2016–25–29 required replacing the cargo compartment insulation blankets on the left and right sides with new insulation blankets that incorporate fire stops. This AD was prompted by a report of a fire in the bilge area of the cargo compartment that burned through the insulation blankets that were intended to prevent smoke from migrating behind the cargo compartment sidewall liners and upward into the main cabin. This AD continues to require the actions in AD 2016–25–29 for certain airplanes. This AD also adds airplanes to the applicability and requires a general visual inspection of the replacement insulation blankets to determine if the blankets are in serviceable condition and correctly installed, and applicable on-condition actions. For certain airplanes, this AD also requires an inspection to determine the insulation blanket part number installed; replacement of additional insulation blankets; and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products. 
DATES : This AD is effective July 29, 
2021. 
The Director of the Federal Register 
approved the incorporation by reference of a certain publications listed in this AD as of July 29, 2021.
