Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2019-02932

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, -400, and -500 series airplanes. This AD was prompted by a report indicating the passenger service units (PSUs) became separated from their attachments during several survivable accident sequences. This AD requires installing lanyard assemblies on the PSU and, for certain airplanes, on the life vest panel. We are issuing this AD to address the unsafe condition on these products.
