Airworthiness Directives; Bombardier Model CL-215-6B11 (CL-415 Variant) Series Airplanes

This action withdraws a direct final rule with request for comments that adopted a new airworthiness directive (AD), applicable to all Bombardier Model CL-215-6B11 (CL-415 Variant) series airplanes. That action would have required revising the Airplane Flight Manual (AFM) to provide the flightcrew with procedures to address a temporary loss of battery bus power during engine failure and consequent erroneous indications of hydraulic system pressure, brake pressure, rudder pressure, and rudder and elevator reversion to manual mode. Since the issuance of the direct final rule, the Federal Aviation Administration (FAA) has received a written adverse comment. Accordingly, the direct final rule is withdrawn.
