Previously, operators had to perform these inspections repeatedly (following Alert SB205-79-7 Part I) until the helicopter was modified according to Part II of that service bulletin.\n\n**Why it matters**\nThe cancellation reduces maintenance costs and downtime for operators. It indicates that the safety issue originally requiring frequent inspection—likely wear or failure modes in the piston rods—has been adequately addressed through design modifications, fleet changes, or revised risk assessments, making the repetitive inspection unnecessary."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-205-44-cyclic-control-cylinder-assembly-inspection-of-piston-rods-cancelled","history":"/api/acts/ad-bell-205-44-cyclic-control-cylinder-assembly-inspection-of-piston-rods-cancelled/history","analysis":"/api/acts/ad-bell-205-44-cyclic-control-cylinder-assembly-inspection-of-piston-rods-cancelled/analysis","conflicts":"/api/acts/ad-bell-205-44-cyclic-control-cylinder-assembly-inspection-of-piston-rods-cancelled/conflicts","importantCases":"/api/acts/ad-bell-205-44-cyclic-control-cylinder-assembly-inspection-of-piston-rods-cancelled/important-cases","documents":"/api/acts/ad-bell-205-44-cyclic-control-cylinder-assembly-inspection-of-piston-rods-cancelled/documents"}}
