By November 2008, aviation safety officials determined that every aircraft requiring the modification had already been fixed, making the rule obsolete. This cancellation cleans up the rulebook by formally removing a requirement that no longer needs to be followed."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dha-3-14-fairey-reed-propellers-spinner-removal-cancelled","history":"/api/acts/ad-dha-3-14-fairey-reed-propellers-spinner-removal-cancelled/history","analysis":"/api/acts/ad-dha-3-14-fairey-reed-propellers-spinner-removal-cancelled/analysis","conflicts":"/api/acts/ad-dha-3-14-fairey-reed-propellers-spinner-removal-cancelled/conflicts","importantCases":"/api/acts/ad-dha-3-14-fairey-reed-propellers-spinner-removal-cancelled/important-cases","documents":"/api/acts/ad-dha-3-14-fairey-reed-propellers-spinner-removal-cancelled/documents"}}
