This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SP, and 747SR series airplanes, that requires a one-time inspection of each emergency evacuation slide or slide/raft to determine if a certain discrepant hose assembly is installed, and replacement of the hose assembly with a new or serviceable assembly if necessary. This action is necessary to prevent the failure of an emergency evacuation slide or slide/raft to fully inflate during an emergency situation, which could impede an evacuation and result in injury to passengers or airplane crewmembers. This action is intended to address the identified unsafe condition.
