The original rule required a one-time inspection of hose assemblies following a manufacturer's service bulletin (SB No. 611), with compliance due within 10 hours of flying time after December 1978.\n\n**Why it matters:** Since all affected aircraft have now completed the required inspection (the deadline was 30 years prior), the rule is obsolete. This cancellation removes an unnecessary regulatory burden while confirming the safety issue has been addressed across the fleet."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification-cancelled","history":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification-cancelled/history","analysis":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification-cancelled/documents"}}
