Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation, Inc., Model 560 and 560XL airplanes. This AD was prompted by reports of mis-wired fire extinguishing bottles. This AD requires an engine fire extinguisher system functional test, an inspection of the fire extinguisher bottle cartridge wire numbers and yellow ID sleeves for proper identification and legibility, and applicable corrective actions. This AD also requires revising the existing inspection program to incorporate new airworthiness limitations for repetitive inspections of the engine fire extinguisher wiring and, as applicable, auxiliary power unit (APU) fire extinguisher wiring. The FAA is issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Textron Aviation, Inc., Model 560 and 560XL airplanes. This AD
was prompted by reports of mis-wired fire extinguishing bottles. This
AD requires an engine fire extinguisher system functional test, an
inspection of the fire extinguisher bottle cartridge wire numbers and
yellow ID sleeves for proper identification and legibility, and
applicable corrective actions. This AD also requires revising the
existing inspection program to incorporate new airworthiness
limitations for repetitive inspections of the engine fire extinguisher
wiring and, as applicable, auxiliary power unit (APU) fire extinguisher
wiring. The FAA is issuing this AD to address the unsafe condition on
these products.
DATES: This AD is effective July 11, 2025.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 11,
2025.

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 Textron
Aviation, Inc., Model 560 and 560XL airplanes. The NPRM was published
in the Federal Register on March 7, 2025 (90 FR 11495). The NPRM was
prompted by reports of mis-wired fire extinguishing bottles. In the
NPRM, the FAA proposed to require an engine fire extinguisher system
functional test, an inspection of the fire extinguisher bottle
cartridge wire numbers and yellow ID sleeves for proper identification
and legibility, and applicable corrective actions. In the NPRM, the FAA
also proposed to require revising the existing inspection program to
incorporate new airworthiness limitations for repetitive inspections of
the engine fire extinguisher wiring and, as applicable, APU fire
extinguisher wiring. The FAA is issuing this AD to address mis-wired
fire extinguisher bottles that might not activate in the event of an
engine or APU fire and consequently, an unextinguished fire in the
engine nacelle or APU.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from an individual that did not contain
a specific suggestion or request that the FAA can act on.
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.

Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed Textron Aviation Citation Service Letter SL560-26-
02, Revision 1, dated July 31, 2024; and Textron Aviation Citation
Service Letter SL560XL-26-02, Revision 1, dated July 31, 2024. This
material specifies procedures for an engine fire extinguisher system
functional test, inspection of the fire extinguisher bottle cartridge
wire numbers and yellow ID sleeves for proper identification and
legibility and applicable corrective actions. Corrective actions
include installing new yellow ID sleeves and new ring terminals. These
documents are distinct since they apply to different airplane models.
This material 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.
Costs of Compliance
The FAA estimates that this AD affects 1,245 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection..................... Up to 2 work-hours x $0 Up to $170........ Up to $211,650.
$85 per hour = $170.
Test........................... Up to 2 work-hours x 0 Up to $170........ Up to $211,650.
$85 per hour = $170.
Revise existing inspection 1 work-hours x $85 per 0 $85............... $105,825.
program. hour = $85.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
corrective actions that would be required based on the results of the
inspection. The agency has no way of determining the number of aircraft
that might need these corrective actions:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Corrective actions......................... 1 work-hour x $85 per hour = $85... $40 $125
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its 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.
