Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category; serial numbers 7003 through 7067 inclusive, 7069 through 7990 inclusive, and 8000 through 8112 inclusive.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by reports of jamming/malfunctioning of the left-hand engine thrust control mechanism. This AD requires modifying the left-hand engine upper core-cowl. We are issuing this AD to prevent jamming/malfunctioning of the left-hand engine thrust control mechanism, which could lead to loss of control of the airplane.
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 36 months or 6,000 flight hours after the effective date of this AD, whichever occurs first: Modify the left-hand engine upper core-cowl, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-71-033, dated August 24, 2011.
