Airworthiness Directives; Textron Aviation, Inc. (Type Certificate Previously Held by Cessna Aircraft Company) Airplanes

Federal Aviation Administration (FAA), DOT.

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.

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.
