SUPPLEMENTARY INFORMATION:
The FAA is adopting a new
airworthiness directive (AD) for all The
Boeing Company Model 747–100, 747–
100B, 747–100B SUD, 747–200B, 747–
200C, 747–200F, 747–300, 747SR, and
747SP series airplanes. This AD was
prompted by significant changes,
including new or more restrictive
requirements, made to the airworthiness
limitations (AWLs) related to fuel tank
ignition prevention. This AD requires
revising the existing maintenance or
inspection program, as applicable, to
incorporate the latest revision of the
AWLs. The FAA is issuing this AD to
address the unsafe condition on these
products.
SUMMARY:
DATES:
56573
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all The Boeing Company Model
747–100, 747–100B, 747–100B SUD,
747–200B, 747–200C, 747–200F, 747–
300, 747SR, and 747SP series airplanes.
The NPRM published in the Federal
Register on June 2, 2022 (87 FR 33451).
The NPRM was prompted by significant
changes, including new or more
restrictive requirements, made to the
AWLs related to fuel tank ignition
prevention. In the NPRM, the FAA
proposed to require revising the existing
maintenance or inspection program, as
applicable, to incorporate the latest
revision of the AWLs. The FAA is
issuing this AD to address the potential
for ignition sources inside fuel tanks
caused by latent failures, alterations,
repairs, or maintenance actions, which,
in combination with flammable fuel
vapors, could result in a fuel tank
explosion and consequent loss of the
airplane.

Discussion of Final Airworthiness
Directive
Comments
The FAA received comments from the
Air Line Pilots Association,
International (ALPA) and Boeing who
supported the NPRM without change.
Conclusion
The FAA reviewed the relevant data,
considered the 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.

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.

(81 FR 65872, September 26, 2016) (AD
2016–19–03).
(c) Applicability
This AD applies to all The Boeing
Company Model 747–100, 747–100B, 747–
100B SUD, 747–200B, 747–200C, 747–200F,
747–300, 747SR, and 747SP series airplanes,
certificated in any category.
(d) Subject
Air Transport Association (ATA) of
America Code 28, Fuel.
The Amendment
(e) Unsafe Condition
This AD was prompted by significant
changes, including new or more restrictive
requirements, made to the airworthiness
limitations (AWLs) related to fuel tank
ignition prevention. The FAA is issuing this
AD to address the potential for ignition
sources inside fuel tanks caused by latent
failures, alterations, repairs, or maintenance
actions, which, in combination with
flammable fuel vapors, could result in a fuel
tank explosion and consequent loss of the
airplane.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
List of Subjects in 14 CFR Part 39
The FAA estimates that this AD
affects 39 airplanes of U.S. registry. The
FAA estimates the following costs to
comply with this AD:
The FAA has determined that revising
the existing maintenance or inspection
program takes an average of 90 workhours per operator, although the agency
recognizes that this number may vary
from operator to operator. Since
operators incorporate maintenance or
inspection program changes for their
affected fleet(s), the FAA has
determined that a per-operator estimate
is more accurate than a per-airplane
estimate. Therefore, the FAA estimates
the average total cost per operator to be
$7,650 (90 work-hours × $85 per workhour).
VerDate Sep<11>2014
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 all The Boeing Company
Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F,
747-300, 747SR, and 747SP series airplanes. The NPRM published in the
Federal Register on June 2, 2022 (87 FR 33451). The NPRM was prompted
by significant changes, including new or more restrictive requirements,
made to the AWLs related to fuel tank ignition prevention. In the NPRM,
the FAA proposed to require revising the existing maintenance or
inspection program, as applicable, to incorporate the latest revision
of the AWLs. The FAA is issuing this AD to address the potential for
ignition sources inside fuel tanks caused by latent failures,
alterations, repairs, or maintenance actions, which, in combination
with flammable fuel vapors, could result in a fuel tank explosion and
consequent loss of the airplane.
[[Page 56574]]
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from the Air Line Pilots Association,
International (ALPA) and Boeing who supported the NPRM without change.
Conclusion
The FAA reviewed the relevant data, considered the 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 747-100/200/300/SP/SR Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),
D6-13747-CMR, dated September 2020. This service information describes
AWLs that include airworthiness limitation instructions (ALIs) and
critical design configuration control limitations (CDCCLs) tasks
related to fuel tank ignition prevention. 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 39 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the agency recognizes that this number may vary from operator
to operator. Since operators incorporate maintenance or inspection
program changes for their affected fleet(s), the FAA has determined
that a per-operator estimate is more accurate than a per-airplane
estimate. Therefore, the FAA estimates the average total cost per
operator to be $7,650 (90 work-hours x $85 per work-hour).
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.
