Abstract
The FAA is superseding Airworthiness Directive (AD) 2017-18- 05, which applied to all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. AD 2017-18-05 required repetitive replacement or inspection of certain fuse pins, and applicable on-condition actions. This AD was prompted by a report of damage found at the lower trailing edge panels of the left wing and a broken fuse pin of the landing gear beam end fitting. This AD was further prompted by the need for new inspections for cracking of the fuse pin, and the determination that additional airplanes are subject to the unsafe condition. This AD continues to require the actions in AD 2017-18-05 and also requires repetitive replacement of certain fuse pins, repetitive inspections for cracking of the fuse pin, and applicable on-condition actions. This AD also revises the applicability by adding airplanes. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2017-18-05, Amendment 39-19014 (82 FR
41331, August 31, 2017) (AD 2017-18-05). AD 2017-18-05 applied to all
Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-
200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP airplanes.
The NPRM published in the Federal Register on September 19, 2022 (87 FR
57155). The NPRM was prompted by a report of damage at the lower
trailing edge panels of the left wing and a broken fuse pin of the
landing gear beam end fitting. The NPRM was further prompted by the
need for new ultrasonic testing (UT) inspections for cracking of the
fuse pin, and the determination that additional airplanes are subject
to the unsafe condition. In the NPRM, the FAA proposed to continue to
require repetitive replacement, or repetitive magnetic particle or
surface high frequency eddy current (HFEC) inspections, of certain fuse
pins, and applicable on-condition actions. The NPRM also proposed the
option for repetitive replacement of certain corrosion-resistant
(stainless) steel (CRES) and steel alloy fuse pins at the wing landing
gear beam end fitting; and repetitive magnetic particle inspections, or
repetitive HFEC and UT inspections, for cracking of the fuse pin, and
applicable on-condition actions. The NPRM also proposed to revise the
applicability by adding Model 747-8F and 747-8 series airplanes.
The FAA is issuing this AD to address cracking in the fuse pin of
the wing landing gear beam end fitting. A broken fuse pin will not
support the wing landing gear beam, causing damage to the surrounding
structure, including flight control cables and hydraulic systems, which
could result in loss of controllability of the airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Air Line Pilots Association,
International, 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. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. 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 Alert Service Bulletin 747-57A2360,
Revision 1, dated February 9, 2022. This service information specifies
procedures for, depending on airplane configuration, the optional
repetitive replacement of certain steel alloy fuse pins or CRES fuse
pins with new or serviceable fuse pins at the wing landing gear beam
end fitting; and repetitive magnetic particle inspections, or
repetitive surface HFEC and UT inspections, for cracking and corrosion
of the fuse pin of the wing landing gear beam end fitting, and
applicable on-condition actions. On-condition actions include
replacement with steel alloy or CRES fuse pins; and magnetic particle,
surface HFEC, and UT testing inspections for cracks; and replacement of
cracked fuse pins. 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 207 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.
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.
