## Abstract

We are adopting 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 AD was prompted by a report indicating that the lanyard length of the passenger drop down oxygen masks is too long. This AD requires replacing the existing oxygen mask lanyards with lanyards of the correct length. We are issuing this AD to address the unsafe condition on these products.
