              Aeroplane Model

              CL-600-1A11 (CL-600) CL-600-2A12 (CL-601)
              CL-600-2B16 (CL-601-3A/-3R) CL-600-2B16 (CL-604)

            Note 3: Transport Canada AD CF-2002-05R1 refers.

Compliance: For Requirement 1:

                Aeroplanes with 300 or more hours time in service (TIS) since new - Within seven days of the effective date of this Directive, unless Requirement 4 of this Directive has been complied with.

                Aeroplanes with less than 300 hours TIS at the effective date of this Directive - Before reaching 300 hours TIS unless Requirement 4 of this Directive has been complied with.

For Requirement 2:

                Aeroplanes with more than 100 hours TIS since new - At or before accumulating 200 hours TIS from the effective date of this Amendment.

                Aeroplanes with 100 hours TIS or less since new - At or before accumulating 300 hours TIS since new.

            For Requirement 3 - Before further flight after the Requirement 2 check.

            For Requirement 4 - Except as authorised under Requirement 2.c.(ii) above, before returning the aircraft to service following completion of the checks specified under Requirement 2.

            For Requirement 5 - Following compliance with Requirement 4.

            For Requirement 6 - Within 30 days after the effective date of this Amendment. This Amendment becomes effective on 22 December 2004.
            Background: Bombardier Aerospace has determined that the potentiometers of the angle of attack transducers can develop flat spots which can cause a delay in the commands for stall warning, stick shaker and stick pusher operation. The problem is dormant and an out- of-tolerance AOA transducer can only be identified on an in service aircraft through introduction of a special check.

            The original issue of this Directive required the amendment of the AFM and special checks of AOA transducers.

            This Amendment amends the applicability for CL-604 aeroplanes, corrects the reference for the CL-604 AFM TR, deletes the repetitive AOA checks required by the original issue of this Directive and introduces an AOA check in the TLMC of the applicable AMM.

            The original issue of this Airworthiness Directive became effective on 6 March 2002.
