## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440); 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 reports of incorrect deployment of forward and aft flight attendant oxygen masks. This proposed AD would require repacking the flight attendant and lavatory oxygen box assemblies as applicable, replacing the placards, and re- identifying the assemblies. We are proposing this AD to address the unsafe condition on these products.
