## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This proposed AD was prompted by a report indicating that the lanyard length of the passenger drop down oxygen masks is too long. This proposed AD would require replacing the existing oxygen mask lanyards with lanyards of the correct length. We are proposing this AD to address the unsafe condition on these products.
