AD/B747/43 - Door Mounted Escape Slide/Raft Girt Bar Attachment Assembly - Inspection and Replacement

This directive requires operators of Boeing 747s fitted with specified B.F. Goodrich lightweight slide/raft girt bar assemblies to inspect—and replace where required—the door‑mounted escape slide/raft girt bar attachment assembly. Compliance follows Boeing SB 25A2665 R1 and B.F. Goodrich SB 25‑093.

It addresses reported separation of sewn quick‑disconnect loops that allowed slide detachment during evacuation, so it affects aircraft operators, maintenance organisations and parts suppliers and imposes inspection, replacement and associated costs on operators.
