Airworthiness Directive · Amendment 39-11914 · Bombardier Model CL-600-2B19 Series Airplanes
Bombardier Model CL-600-2B19 Series Airplanes
Model CL-600-2B19 series airplanes, serial numbers 7003 through 7323 inclusive, certificated in any category.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier Model CL-600-2B19 series airplanes. This action requires installation of shields for the aileron quadrants in the wheel bay of the main landing gear (MLG). This action is necessary to prevent the accumulation of water, ice, or slush on the aileron quadrants and control cable pulleys in the wheel bay of the MLG, which could freeze and result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
To prevent reduced controllability of the airplane due to an accumulation of water, ice, and slush on the aileron quadrants and control cable pulleys in the wheel bay of the main landing gear (MLG); accomplish the following:
(a) Within 30 days after the effective date of this AD, install splash shields in the wheel bin of the MLG in accordance with Bombardier Service Bulletin 601R-27-104, dated October 15, 1999.
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.
