Compliance was originally required before February 1969.\n\n**What this document does:**\nIt officially **cancels** that old requirement effective **20 November 2008**.\n\n**Why it matters:**\nThe safety modification is no longer considered necessary, so this removes an obsolete compliance burden from aircraft owners and operators. If you operate a Piper PA-25 Pawnee, you no longer need to meet this specific seatbelt requirement."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-25-28-inertia-reel-installation-cancelled","history":"/api/acts/ad-pa-25-28-inertia-reel-installation-cancelled/history","analysis":"/api/acts/ad-pa-25-28-inertia-reel-installation-cancelled/analysis","conflicts":"/api/acts/ad-pa-25-28-inertia-reel-installation-cancelled/conflicts","importantCases":"/api/acts/ad-pa-25-28-inertia-reel-installation-cancelled/important-cases","documents":"/api/acts/ad-pa-25-28-inertia-reel-installation-cancelled/documents"}}
