Abstract
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD requires a detailed inspection of the circuit breakers, replacement of damaged circuit breakers, and installation of a circuit breaker bushing assembly. This AD was prompted by a report of cracks found in the plastic casing of cockpit circuit breaker panels. We are issuing this AD to address the unsafe condition on these products.
