Airworthiness Directives; Bombardier, Inc., Airplanes

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by a report indicating that certain lanyards for the passenger oxygen masks located in the airplane's entry area are too long. This proposed AD would require replacement of certain oxygen mask lanyards with shorter lanyards. We are proposing this AD to address the unsafe condition on these products.
