| Requirement: | 1. a. Amend the Aircraft Flight Manual (AFM) by inserting the following Temporary Revisions, as applicable:CL-600-1A11 (CL-600):PSP 600 (DOT) TR 600/26-2, dated 07 August 08PSP 600-1 (DOT) TR 600-1/22-2, dated 07 August 08CL-600-2A12 (CL-601):PSP 601-1A TR 601/30-2, dated 07 August 08PSP 601-1A-1 TR 601/18-2, dated 07 August 08PSP 601-1B TR 601/22-2, dated 07 August 08PSP 601-1B-1 TR 601/17-2, dated 07 August 08CL-600-2B16 (CL-601-3A/3R):PSP 601A-1 TR 601/29-2, dated 07 August 08PSP 601A-1-1 TR 601/30-2, dated 07 August 08CL-600-2B16 (CL-604):PSP 604-1 TR 604/24-2, dated 07 August 08CL-600-2B16 (CL-605):PSP 605-1 TR 605/1-2, dated 07 August 08b. Insert a copy of this Airworthiness Directive in the AFM.Note 1: This AD is applicable to all Challenger CL-600, 601, 601-3A/3R, 604 and 605 models. If the operator has an AFM that is not listed above, consult Bombardier Aerospace.c. Advise all flight crews on the changes introduced through the AFM TR; and,2. Review the “Pilot’s Checklist” to ensure that the instructions regarding selection of the wing anti-ice system to “ON”, as specified in the AFM Limitations Section, are incorporated. |
| Note 2: Canadian Airworthiness Directive No. CF-2008-16R1 dated 20 August 2008 refers. | |
|---|---|
| Compliance: | Within 14 days after the effective date of this directive. |
| This Amendment becomes effective on 6 October 2008. | |
| Background: | Following three recent events where Bombardier CL-600-2B19/CL-600-2B16 aircraft experienced un-commanded roll during take-off, it has been determined that it is necessary to further enhance the AFM limitations and procedures to ensure safe operation, particularly in cold weather or icing conditions.This AD mandates the introduction of additional limitations and procedures to the current AFM and requires that any Operators’ Pilot’s checklists fully reflect these procedures. In order not to compromise the takeoff operational safety margin, strict adherence to all the AFM procedures and limitations is required.This amendment introduces the latest revision to the AFM. The latest AFM revision requires specific pilot training with regard to enhanced take-off procedures and winter operations.The original issue of this AD became effective 13 March 2008. |
