Airworthiness Directives; The Boeing Company Model 767-200, -300, and -400ER Series Airplanes

Краткое содержание

We propose to supersede an existing airworthiness directive (AD) that applies to the products listed above. The existing AD currently requires replacing the separation link assembly on the applicable entry and service doors with an improved separation link assembly, and doing related investigative and corrective actions if necessary. Since we issued that AD, we have received a report that an additional airplane is subject to the unsafe condition. This proposed AD would add that airplane to the applicability and also remove certain other airplanes from the applicability. We are proposing this AD to prevent failure of an entry or service door to open fully in the event of an emergency evacuation, which could impede exit from the airplane. This condition could result in injury to passengers or crewmembers.
