Background
The electrical bonding of the engine
fuel feed tube penetrating the fuel tanks
of Boeing Model 747–8 series airplanes
and other models is the primary design
feature to prevent the development of an
ignition source inside the fuel tank
during a lightning strike to the engine
nacelle. The fuel feed lightning
protection features include the spar
fitting that redirects the majority of
current during a lightning event. A
separate bonding jumper outside the
fuel tank provides a second electrical
path for current from lightning strikes.
The encapsulation sealant over the fuel
tank wall fitting inside the fuel tank
provides additional protection.
However, Boeing has recently
discovered that the bonding jumper
outside the fuel tank is failing at an
excessive rate in addition to the known
degradation of the primary electrical
bonding path through the spar fitting.
Furthermore, Boeing has reported
finding a complete crack around the
circumference of the fuel feed fitting
encapsulation inside a fuel tank of a
Model 747–8 series airplane. This
encapsulation is designed to isolate any
VerDate Sep<11>2014
15:59 Nov 29, 2023
Jkt 262001
sparks/arcing generated during a
lightning strike because of failed
electrical bonds from flammable fuel
vapors in the tank. This is an urgent
safety issue, as all fuel feed lightning
protection features now have evidence
of compromise. The FAA has
determined that all Model 747 airplanes
are affected by the unsafe condition.
A lightning strike to an engine nacelle
combined with a latent failure of the
lightning protection features for the
engine fuel feed system, if not
addressed, could result in the potential
for ignition sources inside fuel tanks,
which, in combination with flammable
fuel vapors, could result in a fuel tank
explosion and consequent loss of the
airplane. The FAA is issuing this AD to
address the unsafe condition on these
products.
FAA’s Determination
The FAA is issuing this AD because
the agency has determined the unsafe
condition described previously is likely
to exist or develop in other products of
the same type design.
Related Service Information Under 1
CFR Part 51
The FAA reviewed the following
service information. These documents
are distinct since they apply to different
airplane models.

airplanes: Boeing Multi Operator
Message MOM–MOM–23–0885–01B–
R1, dated November 13, 2023.
• For Model 747–400, 747–400D, and
747–400F series airplanes: Boeing Multi
Operator Message MOM–MOM–23–
0899–01B–R1, dated November 13,
2023. (For the 747–400D, see the
Differences Between this AD and the
Service Information section below.)
• For Model 747–100, 747–100B,
747–100B SUD, 747–200B, 747–200C,
747–200F, 747–300, 747SR, and 747SP
series airplanes: Boeing Multi Operator
Message MOM–MOM–23–0907–01B,
dated November 13, 2023.
This service information specifies
procedures for a detailed inspection for
damage and a measurement of the
electrical bonding resistance of the outtank fuel feed tube bonding jumper in
the strut for each of the four engines,
and a measurement of the electrical
bonding resistance of the forward side
of the front spar bulkhead fitting adapter
for each of the four engines. The
detailed inspection for damage includes
making sure the bonding jumper
installation is secure.
This service information also specifies
related investigative actions, which
include, depending on the airplane
configuration, a general visual

inspection of the aft side of the front
spar to identify the configuration of the
fuel feed tube and bulkhead fitting
adapter, a detailed inspection for
damage and measurements of the
electrical bonding resistance of the intank bonding jumper, a general visual
inspection of the wet-side front spar
bulkhead fitting adapter for missing and
damaged sealant or for missing sealant
and damage to the encapsulation seal,
and a general visual inspection of the
seal for the welded tube fitting
configuration for missing and damaged
sealant.
This service information also specifies
corrective actions, which include,
depending on the airplane
configuration, adjusting the installation
and reworking the bonding jumper
bonding path, replacement of the
bonding jumper; and re-installing the
front spar bulkhead fitting and applying
sealant.
This service information also specifies
reporting findings of the inspections
and measurements to Boeing.
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.
AD Requirements
This AD requires an inspection for
damage and a measurement of the
electrical bonding resistance of the outtank fuel feed tube bonding jumper in
the strut for each of the four engines, a
measurement of the electrical bonding
resistance of the forward side of the
front spar bulkhead fitting adapter for
each of the four engines, applicable
related investigative and corrective
actions, and reporting inspection and
measurement findings to Boeing.
Differences Between This AD and the
Service Information
For Boeing Multi Operator Message
MOM–MOM–23–0899–01B–R1, dated
November 13, 2023, which applies to
Model 747–400 and 747–400F series
airplanes, the FAA has determined that
Model 747–400D airplanes can also
accomplish the required actions using
that service information. Model 747–
400D airplanes are similar in design to
Model 747–400 and 747–400F series
airplanes.
Interim Action
This AD is considered to be interim
action. The inspection reports that are
required by this AD will enable the
manufacturer to obtain better insight
into the nature, cause, and extent of the
bonding degradation and failures, and
eventually to develop final action to
E:\FR\FM\30NOR1.SGM
30NOR1
83496
Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Rules and Regulations
address the unsafe condition. Once final
action has been identified, the FAA
might consider further rulemaking.
Justification for Immediate Adoption
and Determination of the Effective Date
Section 553(b)(3)(B) of the
Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies
to dispense with notice and comment
procedures for rules when the agency,
for ‘‘good cause,’’ finds that those
procedures are ‘‘impracticable,
unnecessary, or contrary to the public
interest.’’ Under this section, an agency,
upon finding good cause, may issue a
final rule without providing notice and
seeking comment prior to issuance.
Further, section 553(d) of the APA
authorizes agencies to make rules
effective in less than thirty days, upon
a finding of good cause.
An unsafe condition exists that
requires the immediate adoption of this
AD without providing an opportunity
for public comments prior to adoption.
The FAA has found that the risk to the
flying public justifies forgoing notice
and comment prior to adoption of this
rule because the lightning protection
features for the engine fuel feed system
could fail without being detected. This
could result in no lightning protection
features remaining due to the latent
failure. A lightning strike to an engine
nacelle, in combination with flammable
fuel vapors, could result in a fuel tank
explosion and consequent loss of the
airplane. Accordingly, notice and
opportunity for prior public comment
are impracticable and contrary to the
public interest pursuant to 5 U.S.C.
553(b)(3)(B).
In addition, the FAA finds that good
cause exists pursuant to 5 U.S.C. 553(d)
for making this amendment effective in
less than 30 days, for the same reasons
the FAA found good cause to forgo
notice and comment.
Regulatory Flexibility Act
The requirements of the Regulatory
Flexibility Act (RFA) do not apply when
an agency finds good cause pursuant to
5 U.S.C. 553 to adopt a rule without
prior notice and comment. Because the
FAA has determined that it has good
cause to adopt this rule without notice
and comment, RFA analysis is not
required.
Costs of Compliance
The FAA estimates that this AD
affects 211 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this AD:

Dorsey, Aviation Safety Engineer, FAA, 2200 South 216th St., Des
Moines, WA 98198; phone: 206-231-3415; email: [email protected].
Any commentary that the FAA receives that is not specifically
designated as CBI will be placed in the public docket for this
rulemaking.
Background
The electrical bonding of the engine fuel feed tube penetrating the
fuel tanks of Boeing Model 747-8 series airplanes and other models is
the primary design feature to prevent the development of an ignition
source inside the fuel tank during a lightning strike to the engine
nacelle. The fuel feed lightning protection features include the spar
fitting that redirects the majority of current during a lightning
event. A separate bonding jumper outside the fuel tank provides a
second electrical path for current from lightning strikes. The
encapsulation sealant over the fuel tank wall fitting inside the fuel
tank provides additional protection.
However, Boeing has recently discovered that the bonding jumper
outside the fuel tank is failing at an excessive rate in addition to
the known degradation of the primary electrical bonding path through
the spar fitting. Furthermore, Boeing has reported finding a complete
crack around the circumference of the fuel feed fitting encapsulation
inside a fuel tank of a Model 747-8 series airplane. This encapsulation
is designed to isolate any sparks/arcing generated during a lightning
strike because of failed electrical bonds from flammable fuel vapors in
the tank. This is an urgent safety issue, as all fuel feed lightning
protection features now have evidence of compromise. The FAA has
determined that all Model 747 airplanes are affected by the unsafe
condition.
A lightning strike to an engine nacelle combined with a latent
failure of the lightning protection features for the engine fuel feed
system, if not addressed, could result in the potential for ignition
sources inside fuel tanks, which, in combination with flammable fuel
vapors, could result in a fuel tank explosion and consequent loss of
the airplane. The FAA is issuing this AD to address the unsafe
condition on these products.
FAA's Determination
The FAA is issuing this AD because the agency has determined the
unsafe condition described previously is likely to exist or develop in
other products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following service information. These documents
are distinct since they apply to different airplane models.
For Model 747-8 and 747-8F series airplanes: Boeing Multi
Operator Message MOM-MOM-23-0885-01B-R1, dated November 13, 2023.
For Model 747-400, 747-400D, and 747-400F series
airplanes: Boeing Multi Operator Message MOM-MOM-23-0899-01B-R1, dated
November 13, 2023. (For the 747-400D, see the Differences Between this
AD and the Service Information section below.)
For Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-
200C, 747-200F, 747-300, 747SR, and 747SP series airplanes: Boeing
Multi Operator Message MOM-MOM-23-0907-01B, dated November 13, 2023.
This service information specifies procedures for a detailed
inspection for damage and a measurement of the electrical bonding
resistance of the out-tank fuel feed tube bonding jumper in the strut
for each of the four engines, and a measurement of the electrical
bonding resistance of the forward side of the front spar bulkhead
fitting adapter for each of the four engines. The detailed inspection
for damage includes making sure the bonding jumper installation is
secure.
This service information also specifies related investigative
actions, which include, depending on the airplane configuration, a
general visual inspection of the aft side of the front spar to identify
the configuration of the fuel feed tube and bulkhead fitting adapter, a
detailed inspection for damage and measurements of the electrical
bonding resistance of the in-tank bonding jumper, a general visual
inspection of the wet-side front spar bulkhead fitting adapter for
missing and damaged sealant or for missing sealant and damage to the
encapsulation seal, and a general visual inspection of the seal for the
welded tube fitting configuration for missing and damaged sealant.
This service information also specifies corrective actions, which
include, depending on the airplane configuration, adjusting the
installation and reworking the bonding jumper bonding path, replacement
of the bonding jumper; and re-installing the front spar bulkhead
fitting and applying sealant.
This service information also specifies reporting findings of the
inspections and measurements to Boeing.
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.
AD Requirements
This AD requires an inspection for damage and a measurement of the
electrical bonding resistance of the out-tank fuel feed tube bonding
jumper in the strut for each of the four engines, a measurement of the
electrical bonding resistance of the forward side of the front spar
bulkhead fitting adapter for each of the four engines, applicable
related investigative and corrective actions, and reporting inspection
and measurement findings to Boeing.
Differences Between This AD and the Service Information
For Boeing Multi Operator Message MOM-MOM-23-0899-01B-R1, dated
November 13, 2023, which applies to Model 747-400 and 747-400F series
airplanes, the FAA has determined that Model 747-400D airplanes can
also accomplish the required actions using that service information.
Model 747-400D airplanes are similar in design to Model 747-400 and
747-400F series airplanes.
Interim Action
This AD is considered to be interim action. The inspection reports
that are required by this AD will enable the manufacturer to obtain
better insight into the nature, cause, and extent of the bonding
degradation and failures, and eventually to develop final action to
[[Page 83496]]
address the unsafe condition. Once final action has been identified,
the FAA might consider further rulemaking.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because the lightning protection features for the engine fuel feed
system could fail without being detected. This could result in no
lightning protection features remaining due to the latent failure. A
lightning strike to an engine nacelle, in combination with flammable
fuel vapors, could result in a fuel tank explosion and consequent loss
of the airplane. Accordingly, notice and opportunity for prior public
comment are impracticable and contrary to the public interest pursuant
to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forgo notice and
comment.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 211 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

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.
[[Page 83497]]

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, and
(2) Will not affect intrastate aviation in Alaska.
