Résumé
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) series airplanes. This AD requires revising the airplane flight manual to provide the flightcrew with procedures and limitations for operating an airplane with out-of-tolerance angle of attack (AOA) transducers. This AD also requires repetitive linearity tests of the AOA transducers, and corrective action if necessary. This AD is prompted by a report of premature wear of the potentiometers in AOA transducers having a certain part number. We are issuing this AD to prevent a delay in the stall computer commands for stall warning, stick shaker, and stick pusher operation, due to premature wear of the potentiometers of the AOA transducers, which may cause the airplane to enter a stall condition, and result in loss of control of the airplane.
