Airworthiness Directive · Amendment 39-11355 · Bombardier Model CL-600-2B19 (Regional Jet Series 100) Series Airplanes
Bombardier Model CL-600-2B19 (Regional Jet Series 100) Series Airplanes
Model CL-600-2B19 (Regional Jet Series 100) series airplanes, serial numbers 7003 through 7067 inclusive and 7069 through 7250 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) series airplanes, that requires a one-time inspection to detect damage of the input connectors and wiring of the main and auxiliary power unit (APU) battery chargers, and corrective action, if necessary. This amendment also requires installation of secure connectors for the battery charger input connections. In addition, this amendment requires, for certain airplanes, either the installation of a resistor in the battery charger wiring, or the installation of new batteries with internal resistors. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent increased risk of a short circuit and consequent electrical smoke or fire in the aft fuselage.
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.
