The cancelled rule previously required operators to retire certain **fatigue-critical components** (parts that wear out from repeated stress, like rotor blades or gearboxes) after specific flight hours or cycles.\n\n**Why it matters**\n\nThe safety requirements haven't disappeared—they've just moved location. The helicopter manufacturer (Bell Helicopter) now includes these retirement schedules directly in the mandatory **Maintenance Manual Airworthiness Limitations Schedule** (a legally binding section of the aircraft's technical manual). This makes the separate government directive redundant.\n\n**Who is affected**\n\nOwners and operators of Bell 222 series helicopters.\n\n**Key takeaway**\n\nInstead of following this separate CASA directive, operators must now comply with the retirement lives specified in the helicopter's official maintenance manual. The safety standards remain identical; only the paperwork source has changed."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-222-1-retirement-lives-fatigue-critical-components-cancelled","history":"/api/acts/ad-bell-222-1-retirement-lives-fatigue-critical-components-cancelled/history","analysis":"/api/acts/ad-bell-222-1-retirement-lives-fatigue-critical-components-cancelled/analysis","conflicts":"/api/acts/ad-bell-222-1-retirement-lives-fatigue-critical-components-cancelled/conflicts","importantCases":"/api/acts/ad-bell-222-1-retirement-lives-fatigue-critical-components-cancelled/important-cases","documents":"/api/acts/ad-bell-222-1-retirement-lives-fatigue-critical-components-cancelled/documents"}}
