However, this cancellation matters mostly as a paperwork exercise—everyone who needed to comply has already done so.\n\n**Why it matters:** The original rule was a one-time safety check required back in 1978. Because all affected aircraft have now been modified, the authority is formally removing the requirement to reduce unnecessary regulatory burden. The cancellation takes effect on 12 February 2009."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-23-78-amdt-1-hose-assembly-inspection-and-replacement-cancelled","history":"/api/acts/ad-pa-23-78-amdt-1-hose-assembly-inspection-and-replacement-cancelled/history","analysis":"/api/acts/ad-pa-23-78-amdt-1-hose-assembly-inspection-and-replacement-cancelled/analysis","conflicts":"/api/acts/ad-pa-23-78-amdt-1-hose-assembly-inspection-and-replacement-cancelled/conflicts","importantCases":"/api/acts/ad-pa-23-78-amdt-1-hose-assembly-inspection-and-replacement-cancelled/important-cases","documents":"/api/acts/ad-pa-23-78-amdt-1-hose-assembly-inspection-and-replacement-cancelled/documents"}}
