Think of it as a \"recall notice\" for aircraft, but legally binding.\n\n**What it does:** It requires airlines and aircraft operators to inspect and potentially replace a specific part on Boeing 747 aeroplanes — the attachment assembly that connects emergency escape slides to the aircraft door.\n\n**Who it affects:** Anyone operating Boeing 747 aircraft fitted with specific BF Goodrich emergency slide/raft models (part numbers listed: 7A1340, 7A1342, 7A1373, 7A1437, 7A1439, 7A1447, or 7A1448).\n\n**Why it matters:** The directive was issued after a dangerous incident during an emergency evacuation where the quick-release loops that hold the escape slide to the plane **ripped away from their fittings**. This meant the inflatable escape slide detached from the aircraft entirely — potentially trapping passengers inside during an emergency. The directive prevents this catastrophic failure by mandating inspections and replacements according to manufacturer service bulletins.\n\n**What operators must do:** Follow the inspection and replacement procedures detailed in two technical documents: Boeing Service Bulletin 25A2665 Revision 1, and BF Goodrich Service Bulletin 25-093. The directive also references a corresponding US Federal Aviation Administration (FAA) directive (AD 84-24-04) for additional guidance."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b747-43-door-mounted-escape-slide-raft-girt-bar-attachment-assembly-inspection-and-replacement","history":"/api/acts/ad-b747-43-door-mounted-escape-slide-raft-girt-bar-attachment-assembly-inspection-and-replacement/history","analysis":"/api/acts/ad-b747-43-door-mounted-escape-slide-raft-girt-bar-attachment-assembly-inspection-and-replacement/analysis","conflicts":"/api/acts/ad-b747-43-door-mounted-escape-slide-raft-girt-bar-attachment-assembly-inspection-and-replacement/conflicts","importantCases":"/api/acts/ad-b747-43-door-mounted-escape-slide-raft-girt-bar-attachment-assembly-inspection-and-replacement/important-cases","documents":"/api/acts/ad-b747-43-door-mounted-escape-slide-raft-girt-bar-attachment-assembly-inspection-and-replacement/documents"}}
