## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100) airplanes that requires a one-time inspection of the direct current (DC) power distribution system for reliability, and correction or repair, of any fuse holders and associated electrical wiring, if necessary. This amendment is prompted by a report indicating that a loose fuse holder caused the DC power distribution system to short circuit on one of the affected airplanes, which resulted in a burnt wire between circuit breaker panel CBP-2 and junction box JB7. The actions specified by this AD are intended to prevent such short circuiting, which could result in a burnt wire, smoke entering the cockpit area, and consequent passenger injury due to smoke inhalation.
