Airworthiness Directives; Learjet Model 45 Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Learjet Model 45 airplanes. This AD requires modifying the electrical wire bundle for the alternator on the left-hand engine, inspecting for clearance between wire harnesses and engine tubing for each engine, and corrective actions if necessary. For certain airplanes, this AD also requires replacing the fuses for the hydraulic shutoff valves with fuses having higher amperage. This AD results from a report of a fire in the left-hand engine nacelle. We are issuing this AD to prevent chafing between the wire bundle for the alternator on each engine and the hydraulic lines, which could result in a fire in the engine nacelle.
