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. 

List of Subjects in 14 CFR Part 39

(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

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.
