AD 2008-21-09 Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), CL-600-2B16 (CL-601-3A, CL-601-3R, & CL-604 (Including CL-605 Marketing Variant)) Airplanes, and Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

This AD applies to all Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), CL-600-2B16 (CL-601-3A, CL-601-3R, & CL-604) airplanes, and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category. Note 1: Some Model CL-600-2B16 (CL-604) airplanes might be referred to by a marketing designation as CL-605. Note 2: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Restatement of AD 2008-08-06 Revision to Airplane Flight Manual (AFM) (f) Within 7 days after April 21, 2008 (the effective date of AD 2008-08-06), revise the applicable sections of the applicable AFM by inserting a copy of the applicable temporary revision (TR) listed in Table 1 of this AD. Thereafter, operate the airplanes per the limitation specified in the applicable TR, except as provided by paragraphs (h) and (j) of this AD. Doing the revision required by paragraph (h) of this AD terminates the requirements of this paragraph. (g) When information identical to that in a TR specified in paragraph (f) of this AD has been included in the general revisions of the applicable AFM, the general revisions may be inserted into the AFM, and the TR may be removed from that AFM.

This AD results from reports of uncommanded roll during take-off. We are issuing this AD to prevent possible loss of control on take-off resulting from even small amounts of frost, ice, snow, or slush on the wing leading edges or forward upper wing surfaces.
