Bombardier Model CL-600-2B19 (Regional Jet Series 100) and CL-600-2B16 (CL-601-3R and CL-604) Series Airplanes
Model CL-600-2B19 (Regional Jet Series 100) series airplanes, serial numbers 7003 through 7067 inclusive, and 7069 through 7303 inclusive; and Model CL-600-2B16 (CL-601-3R and CL-604) series airplanes, serial numbers 5135 through 5194 inclusive, and 5301 through 5408 inclusive; certificated in any category.
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 99-09-52 that was sent previously to all known U.S. owners and operators of Bombardier Model CL-600-2B19 (Regional Jet Series 100) and CL-600-2B16 (CL-601-3R and CL-604) series airplanes by individual notices. This AD requires a one-time inspection of the cable harness of the integrated drive generator (IDG) in the right engine nacelle and the adjacent structure to verify clearances and detect chafing; a one-time inspection of both the left and right engine nacelles to detect chafing and verify clearances of the adjacent 10th stage bleed air check valve and fuel manifold pigtails; and repair or replacement of discrepant parts, if necessary. This action is prompted by reports of chafing of the insulation covering on the IDG cable harness and the main engine right fuel manifold. The actions specified by this AD are intended to detect and correct concurrent chafing of both the fuel manifold and the IDG wire and subsequent leakage of fuel, which could come in contact with live wiring and result in fire or explosion.
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.
