Airworthiness Directive · Amendment 39-13633 · Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes; serial numbers 7003 through 7067 inclusive, and 7069 through 7782 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, that requires repetitive inspections for cracking of the upper and lower web of the engine support beam between fuselage station (FS) 625 and FS 640, and repair if necessary. This AD also provides an optional terminating action for the repetitive inspections. This action is necessary to prevent failure of the engine support beam, a principal structural element, which could result in reduced structural integrity 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.
