AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain The Boeing Company Model 777 

airplanes. This proposed AD was 

prompted by reports of discrepancies 

between the center wing tank (CWT) 

fuel quantity, as indicated by the fuel 

quantity indicating system (FQIS), and 

the refueling truck uploaded fuel 

amount, followed by certain engineindicating and crew-alerting system 

(EICAS) messages. This proposed AD 

would require installing new software 

in the fuel quantity processor unit 

(FQPU), or replacing the FQPU with one 

that includes new software, depending 

on airplane configuration; and doing a 

software version check and FQPU 

operational check. This proposed AD 

would also prohibit the installation of 

certain FQPUs on certain airplanes. 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 5, 2022.

Background 

The FAA has received reports of 

discrepancies between the airplane 

FQIS, specifically the CWT fuel quantity 

and the refueling truck uploaded fuel 

amount, followed by an engineindicating and crew-alerting system 

(EICAS) FUEL DISAGREE message at an 

early stage of flight (for example, within 

3 hours after takeoff), and/or an EICAS 

INSUFFICIENT FUEL message. At least 

25 in-service events have been reported 

by operators. In at least 17 of these 

events, the airplanes continued with the 

mission; of those, six landed at the 

destination airport, and 11 had to land 

at a diversion airport. 

As a result of those reports, the FAA 

issued AD 2020–11–11, Amendment 

39–19915 (85 FR 34090, June 3, 2020) 

(AD 2020–11–11) for certain The Boeing 

Company Model 777 airplanes. AD 

2020–11–11 requires a repetitive check 

of the FQIS fuel quantity calculation for 

the CWT, developing a process to 

provide documentation to the flight 

crew that this check was done, and 

revising the existing airplane flight 

manual (AFM) to incorporate 

verification procedures and flight crew 

awareness. The preamble to AD 2020– 

11–11 explains that the FAA considered 

the requirements ‘‘interim action’’ and 

was considering further rulemaking. 

The FAA has now determined that 

further rulemaking is indeed necessary, 

and this proposed AD follows from that 

determination. 

Insufficient fuel in the CWT as a 

result of this discrepancy is due to a 

design flaw in the FQIS in which the 

FQIS ultrasonic tank units calibrate 

incorrect velocity of sound (VOS) in the 

jet fuel during center tank fueling, 

which leads to an improper fuel density 

calculation, and results in the FQIS 

showing a different fuel amount from 

the actual fuel quantity in the CWT. 

Current FQPU gauging software is 

subjected to this stale VOS value under 

certain conditions due to insufficient 

VOS reset functions. 

In almost all of the events, the FQIS 

showed more fuel than the actual fuel 

quantity in the CWT, resulting in less 

fuel on the airplane than the required 

fuel load for the mission. Alternatively, 

the FQIS could show less fuel than the 

actual fuel quantity in the CWT, 

resulting in more fuel on the airplane 

than the required fuel load for the 

mission. This issue affects only the 

CWT and not the main tanks. This 

incorrect fuel quantity information is 

also provided to the flight deck Fuel 

Quantity Display and the flight 

management function (FMF) of the 

Airplane Information Management 

System (AIMS). 

The existing airplane maintenance 

manual and operator fueling procedures 

require verification that the correct fuel 

amount required for the current mission 

has been loaded onto the airplane. The 

FAA has received reports that 

verification tasks are either not 

accomplished or done incorrectly. As a 

result, the flight crew may be unaware 

of insufficient fuel loaded in the CWT 

and the airplane is dispatched for the 

mission. The airplane onboard fuel 

management system typically reports 

fuel quantity anomalies within the first 

three hours of flight resulting in a FUEL 

DISAGREE EICAS message and/or an 

INSUFFICIENT FUEL EICAS message 

that necessitates fuel check (e.g., leak 

check) and fuel quantity monitoring. 

These messages may require the flight 

crew to take action, such as performing 

an air turn back or a diversion. 

This AD was prompted by reports of 

discrepancies between the CWT fuel 

quantity, as indicated by the FQIS, and 

the actual amount uploaded from the 

refueling truck. The FAA is issuing this 

AD to address discrepancies in the CWT 

FQIS, which can result in an airplane 

being dispatched with insufficient fuel 

in the CWT and with the flight crew 

unaware of the insufficient fuel prior to 

departure. This condition, coupled with 

continued flight to the destination 

airport after receiving EICAS messages 

while en route to the destination, could 

result in fuel exhaustion and subsequent 

power loss to all engines, thereby 

resulting in the inability to land at the 

destination airport or at a diversion 

airport, possibly leading to flight into 

terrain. 

Other Relevant Rulemaking 

AD 2020–11–11 addresses the same 

unsafe condition addressed by this 

proposed AD. While an operator is 

incorporating the requirements in this 

proposed AD on their fleet, they will 

have a mixed fleet with different 

requirements, depending on whether or 

not the actions in this proposed AD 

have been accomplished on a given 

airplane. This could make it challenging 

for fuel vendors or other personnel to 

determine whether a particular airplane 

needed to undergo the procedures 

required by AD 2020–11–11 when 

fueling that airplane. The FAA has 

therefore determined that the actions 

required by this proposed AD must be 

accomplished on all affected airplanes 

in an operator’s fleet before the 

requirements of AD 2020–11–11 are 

terminated for that fleet. However, once 

the actions required by this proposed 

AD are accomplished on all affected 

airplanes in an operator’s fleet, the 

requirements of AD 2020–11–11 are 

terminated for that fleet. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 777–28A0090 

RB, dated March 30, 2021. This service 

information specifies procedures for a 

check of maintenance or delivery 

records or an inspection to determine 

the part number of the FQPU for Group 

1 airplanes. For Group 1 airplanes with 

a FQIS–1 FQPU, this service 

information specifies procedures for 

removing the existing FQPU and 

installing certain FQIS–2 FQPU with 

upgraded software, and doing a software 

version check and FQPU operational 

check. For Group 1 airplanes with a 

FQIS–2 FQPU and Group 2 airplanes, 

this service information specifies 

procedures for upgrading the FQPU

software and doing a software version 

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. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information already 

described. 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–2022– 

0103. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 257 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Records review or inspection of FQPU part number for Group 1 airplanes 

(143 airplanes).

1 work-hour × $85 per hour = $85 ...... $0 $85 $12,155 

Group 1 with FQIS–1 FQPU (125 airplanes): Replace FQPU with FQIS–2 

FQPU, and do software and FQPU checks.

1 work-hour × $85 per hour = $85 ...... 48,300 48,385 6,048,125 

Group 1 with FQIS–2 FQPU and Group 2 (132 airplanes): Upgrade software 

and do software check.

1 work-hour × $85 per hour = $85 ...... 0 85 11,220 

The FAA has included all known 

costs in its cost estimate. According to 

the software 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.

discrepancies in the CWT FQIS, which can 

result in an airplane being dispatched with 

insufficient fuel in the CWT and with the 

flight crew unaware of the insufficient fuel 

prior to departure. This condition, coupled 

with continued flight to the destination 

airport after receiving engine-indicating and 

crew-alerting system (EICAS) messages while 

in route to the destination, could result in 

fuel exhaustion and subsequent power loss to 

all engines, thereby resulting in the inability 

to land at the destination airport or at a 

diversion airport, possibly leading to flight 

into terrain. 

(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

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of the airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it would 

expand the availability of RNAV in 

Alaska and improve the efficient flow of 

air traffic within the National Airspace 

System (NAS) by lessoning the 

dependency on ground based 

navigation.
