Summary
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), Model CL-600- 2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by a report of a smoke-in-cabin event due to a non-sustaining electrical fire. This proposed AD would require installation of protective sleeves on the bonding jumper wires of affected galleys and lavatories. We are proposing this AD to address the unsafe condition on these products.
