Operators needed to complete this work within 100 hours of flying time after May 1971.\n\n**Why it is being cancelled:** Since this requirement is decades old, every affected helicopter would have completed the fix long ago. This document officially removes the obsolete rule from the aviation safety register.\n\n**Who it affects:** Primarily a housekeeping matter for the Civil Aviation Safety Authority. For helicopter operators, it confirms they no longer need to track this specific directive, though the required safety work remains embedded in the aircraft's maintenance history."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-205-9-servo-cylinder-upper-control-tube-fittings-cancelled","history":"/api/acts/ad-bell-205-9-servo-cylinder-upper-control-tube-fittings-cancelled/history","analysis":"/api/acts/ad-bell-205-9-servo-cylinder-upper-control-tube-fittings-cancelled/analysis","conflicts":"/api/acts/ad-bell-205-9-servo-cylinder-upper-control-tube-fittings-cancelled/conflicts","importantCases":"/api/acts/ad-bell-205-9-servo-cylinder-upper-control-tube-fittings-cancelled/important-cases","documents":"/api/acts/ad-bell-205-9-servo-cylinder-upper-control-tube-fittings-cancelled/documents"}}
