It applies to any safety belt or harness that relies on a **wedging mechanism**—where the fabric webbing is held in place by spring pressure squeezing it between two metal pieces, with at least one of those pieces having a serrated (rough, jagged) or knurled (cross-hatched) surface.\n\n**What must happen:**\n- These specific belts must be removed from all aircraft service\n- The compliance deadline was set for before 1 January 1977\n\n**Why it matters:**\nThis addresses a safety defect in the locking design. The wedging mechanism could potentially slip or fail during turbulence or impact, failing to restrain passengers and crew when needed most."}},"importantCases":[],"_links":{"self":"/api/acts/ad-res-9-unapproved-safety-belts-and-harnesses-removal-from-service","history":"/api/acts/ad-res-9-unapproved-safety-belts-and-harnesses-removal-from-service/history","analysis":"/api/acts/ad-res-9-unapproved-safety-belts-and-harnesses-removal-from-service/analysis","conflicts":"/api/acts/ad-res-9-unapproved-safety-belts-and-harnesses-removal-from-service/conflicts","importantCases":"/api/acts/ad-res-9-unapproved-safety-belts-and-harnesses-removal-from-service/important-cases","documents":"/api/acts/ad-res-9-unapproved-safety-belts-and-harnesses-removal-from-service/documents"}}
