## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to all Boeing Model 747SP, 747SR, 747-100, - 100B, -100B SUD, -200B, -200C, -200F, and -300 series airplanes, that would have required modification of the escape slide/raft pack assembly and cable release sliders. This new action revises the proposed rule by incorporating new service information, which clarifies the airplanes on which certain actions must be done, and by adding a new requirement for certain airplanes. The actions specified by this new proposed AD are intended to prevent improper deployment of the escape slide/raft or blockage of the passenger/crew doors in the event of an emergency evacuation, which could result in injury to passengers or crewmembers. This action is intended to address the identified unsafe condition.
