Airworthiness Directive · Amendment 39-12841 · Bombardier Model CL-600-2B19 Series Airplanes
Bombardier Model CL-600-2B19 Series Airplanes
All Model CL-600-2B19 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Bombardier Model CL-600-2B19 series airplanes. This action requires revising the Airworthiness Limitations section of the maintenance requirements manual to incorporate life limits for certain horizontal stabilizer trim actuators (HSTAs), and replacing the HSTAs with new or serviceable HSTAs. This action is necessary to prevent failure of key components of the HSTAs, which could result in loss of horizontal trim control and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
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.
