Airworthiness Directive · Amendment 39-12716 · Bombardier Model CL-600-2B16 (CL-601-3R and CL-604) Series Airplanes
Bombardier Model CL-600-2B16 (CL-601-3R and CL-604) Series Airplanes
Model CL-600-2B16 (CL-601-3R) series airplanes, serial numbers 5135 through 5194 inclusive; and Model CL-600-2B16 (CL-604) series airplanes, serial numbers 5301 through 5481 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier Model CL-600-2B16 (CL-601-3R and CL-604) series airplanes. This action requires a one-time inspection to detect chafing and other damage of the integrated drive generator (IDG) cables on both left and right engines between the service pylon connections to the IDG, corrective action if necessary, and installation of protective Teflon tubing and additional clamps on the IDG cable harnesses. This action is necessary to prevent electrical arcing between the IDG cable and the engine cowling, which could result in in-flight fire and/or loss of electrical power. 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.
