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.
Within 2,400 flight hours or 60 months, whichever occurs first after the effective date of this AD, replace the existing lanyards in the passenger oxygen box assemblies with lanyards of the correct length, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 605-35-003, Revision 02, dated April 18, 2016.
