Airworthiness Directive · Amendment 39-13414 · 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 7573 inclusive, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 series airplanes (Regional Jet Series 100 & 440), that requires a one-time inspection of the dust covers for the flight data recorder (FDR) and cockpit voice recorder (CVR) equipment for the presence of markings that indicate the presence of a chemical-resistant coating, and corrective actions if necessary. The actions specified by this AD are intended to prevent peeling of the paint and markings from the dust covers for FDR and CVR equipment due to hydraulic mist from the actuators, which could result in the inability to identify FDR and CVR equipment in the event of an accident-recovery mission. The lack of data from FDR and CVR equipment could hamper discovery of the unsafe condition that caused an accident or an incident and prevent the FAA from developing and mandating actions to prevent additional accidents or incidents caused by that same unsafe condition. 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.
