AIRWORTHINESS DIRECTIVE

The following airworthiness directive (AD) may be applicable to an aircraft which our records indicate is registered in your name.  ADs are issued pursuant to Canadian Aviation Regulation (CAR) 593.  Pursuant to CAR 605.84 and the further details of CAR Standard 625, Appendix H, the continuing airworthiness of a Canadian registered aircraft is contingent upon compliance with all applicable ADs.  Failure to comply with the requirements of an AD may invalidate the flight authorization of the aircraft.  Alternative means of compliance shall be applied for in accordance with CAR 605.84 and the above-referenced Standard.

This AD has been issued by the Continuing Airworthiness Division (AARDG), Aircraft Certification Branch, Transport Canada, Ottawa, telephone
613-952-4357.

Number: CF-2008-15R1
Subject: Enhancement to Takeoff Operational Safety Margins
Effective: 3 September 2008
Revision: Supersedes Airworthiness Directive CF-2008-15 issued on 7 March 2008
Applicability: All Bombardier Inc. Model CL-600-2B19 aircraft.
Compliance: When indicated, unless already accomplished.
Background: Following three recent accidents/incidents where Bombardier CL-600-2B19/CL-600-2B16 aircraft experienced un-commanded roll during take–off, Transport Canada Civil Aviation (TCCA) has determined that it is necessary to further enhance the airplane flight manual (AFM) limitations and procedures to ensure safe operation, particularly in cold weather or icing conditions.
The original issue of this directive mandated the introduction of additional limitations and procedures to the AFM and required that any operator’s Pilot’s Checklist fully reflects these procedures. In order not to compromise the takeoff operational safety margin, strict adherence to all the AFM procedures and limitations was required.
Revision 1 of this directive mandates the amendment of the AFM by inserting Temporary revision (TR) RJ/155-5 which, in addition to retaining the limitations and procedures introduced to the AFM Limitations Section through AFM TR RJ/155-2, now also requires specific pilot training on or before 1 November 2008 with regard to enhanced take-off procedures and winter operations.
Corrective
Action:
Part I – AFM Changes.

• Insert a copy of this directive in the AFM.
• Advise all flight crews on the changes introduced through the AFM TR.
Part II – Operator’s Pilot’s Checklist.
Within 14 days after 10 March 2008 (the effective date of the original issue of this    directive), 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.
