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.
