Airworthiness Directive · Amendment 39-13979 · Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes and Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) Series Airplanes
Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes and Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) Series Airplanes
Superseded. A later AD replaced this one: AD 2008-08-06. Comply with the one in force.
This AD applies to all Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes and Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, & CL-604) series airplanes; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes and Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) series airplanes. This AD requires revising the airplane flight manuals to include a new cold weather operations limitation. This AD is prompted by a report that even small amounts of frost, ice, snow, or slush on the wing leading edges or forward upper wing surfaces can cause an adverse change in the stall speeds, stall characteristics, and the protection provided by the stall protection system. 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 5 days after the effective date of this AD, revise the applicable Bombardier AFMs, Chapter 2 Limitations—Operating Limitations section, by inserting a copy of the new cold weather operations limitation specified in the Canadair (Bombardier) temporary revisions (TRs) listed in Table 1 of this AD. Thereafter, operate the airplanes per the limitation specified in the applicable TR, except as provided by paragraph (g) of this AD.

Note 1: 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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
