Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767 series airplanes. This proposal would require removing the two existing escape ropes in the flight compartment; installing new escape ropes, bags, and placards; and replacing the nylon straps with new straps; as applicable. This action is necessary to ensure that flight crew members safely reach the ground from a flight compartment window in the event of an emergency evacuation. This action is intended to address the identified unsafe condition.
